# saslprep
_Note: This is a fork of the original [`saslprep`](https://www.npmjs.com/package/saslprep) npm package
and provides equivalent functionality._
Stringprep Profile for User Names and Passwords, [rfc4013](https://tools.ietf.org/html/rfc4013)
### Usage
```js
const saslprep = require('@mongodb-js/saslprep');
saslprep('password\u00AD'); // password
saslprep('password\u0007'); // Error: prohibited character
```
### API
##### `saslprep(input: String, opts: Options): String`
Normalize user name or password.
##### `Options.allowUnassigned: bool`
A special behavior for unassigned code points, see https://tools.ietf.org/html/rfc4013#section-2.5. Disabled by default.

Higher level content negotiation based on [negotiator](https://www.npmjs.com/package/negotiator).
Extracted from [koa](https://www.npmjs.com/package/koa) for general use.
In addition to negotiator, it allows:
- Allows types as an array or arguments list, ie `(['text/html', 'application/json'])`
as well as `('text/html', 'application/json')`.
- Allows type shorthands such as `json`.
- Returns `false` when no types match
- Treats non-existent headers as `*`
## Installation
This is a [Node.js](https://nodejs.org/en/) module available through the
[npm registry](https://www.npmjs.com/). Installation is done using the
[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
```sh
$ npm install accepts
```
## API
```js
var accepts = require('accepts')
```
### accepts(req)
Create a new `Accepts` object for the given `req`.
#### .charset(charsets)
Return the first accepted charset. If nothing in `charsets` is accepted,
then `false` is returned.
#### .charsets()
Return the charsets that the request accepts, in the order of the client's
preference (most preferred first).
#### .encoding(encodings)
Return the first accepted encoding. If nothing in `encodings` is accepted,
then `false` is returned.
#### .encodings()
Return the encodings that the request accepts, in the order of the client's
preference (most preferred first).
#### .language(languages)
Return the first accepted language. If nothing in `languages` is accepted,
then `false` is returned.
#### .languages()
Return the languages that the request accepts, in the order of the client's
preference (most preferred first).
#### .type(types)
Return the first accepted type (and it is returned as the same text as what
appears in the `types` array). If nothing in `types` is accepted, then `false`
is returned.
The `types` array can contain full MIME types or file extensions. Any value
that is not a full MIME type is passed to `require('mime-types').lookup`.
#### .types()
Return the types that the request accepts, in the order of the client's
preference (most preferred first).
## Examples
### Simple type negotiation
This simple example shows how to use `accepts` to return a different typed
respond body based on what the client wants to accept. The server lists it's
preferences in order and will get back the best match between the client and
server.
```js
var accepts = require('accepts')
var http = require('http')
function app (req, res) {
var accept = accepts(req)
// the order of this list is significant; should be server preferred order
switch (accept.type(['json', 'html'])) {
case 'json':
res.setHeader('Content-Type', 'application/json')
res.write('{"hello":"world!"}')
break
case 'html':
res.setHeader('Content-Type', 'text/html')
res.write('<b>hello, world!</b>')
break
default:
// the fallback is text/plain, so no need to specify it above
res.setHeader('Content-Type', 'text/plain')
res.write('hello, world!')
break
}
res.end()
}
http.createServer(app).listen(3000)
```
You can test this out with the cURL program:
```sh
curl -I -H'Accept: text/html' http://localhost:3000/
```

Node.js body parsing middleware.
Parse incoming request bodies in a middleware before your handlers, available
under the `req.body` property.
**Note** As `req.body`'s shape is based on user-controlled input, all
properties and values in this object are untrusted and should be validated
before trusting. For example, `req.body.foo.toString()` may fail in multiple
ways, for example the `foo` property may not be there or may not be a string,
and `toString` may not be a function and instead a string or other user input.
[Learn about the anatomy of an HTTP transaction in Node.js](https://nodejs.org/en/learn/http/anatomy-of-an-http-transaction).
_This does not handle multipart bodies_, due to their complex and typically
large nature. For multipart bodies, you may be interested in the following
modules:
* [busboy](https://www.npmjs.com/package/busboy#readme) and
[connect-busboy](https://www.npmjs.com/package/connect-busboy#readme)
* [multiparty](https://www.npmjs.com/package/multiparty#readme) and
[connect-multiparty](https://www.npmjs.com/package/connect-multiparty#readme)
* [formidable](https://www.npmjs.com/package/formidable#readme)
* [multer](https://www.npmjs.com/package/multer#readme)
This module provides the following parsers:
* [JSON body parser](#bodyparserjsonoptions)
* [Raw body parser](#bodyparserrawoptions)
* [Text body parser](#bodyparsertextoptions)
* [URL-encoded form body parser](#bodyparserurlencodedoptions)
Other body parsers you might be interested in:
- [body](https://www.npmjs.com/package/body#readme)
- [co-body](https://www.npmjs.com/package/co-body#readme)
## Installation
```sh
$ npm install body-parser
```
## API
```js
const bodyParser = require('body-parser')
```
The `bodyParser` object exposes various factories to create middlewares. All
middlewares will populate the `req.body` property with the parsed body when
the `Content-Type` request header matches the `type` option.
The various errors returned by this module are described in the
[errors section](#errors).
### bodyParser.json([options])
Returns middleware that only parses `json` and only looks at requests where
the `Content-Type` header matches the `type` option. This parser accepts any
Unicode encoding of the body and supports automatic inflation of `gzip`,
`br` (brotli) and `deflate` encodings.
A new `body` object containing the parsed data is populated on the `request`
object after the middleware (i.e. `req.body`).
#### Options
The `json` function takes an optional `options` object that may contain any of
the following keys:
##### defaultCharset
Specify the default character set for the json content if the charset is not
specified in the `Content-Type` header of the request. Defaults to `utf-8`.
##### inflate
When set to `true`, then deflated (compressed) bodies will be inflated; when
`false`, deflated bodies are rejected. Defaults to `true`.
##### limit
Controls the maximum request body size. If this is a number, then the value
specifies the number of bytes; if it is a string, the value is passed to the
[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults
to `'100kb'`.
##### reviver
The `reviver` option is passed directly to `JSON.parse` as the second
argument. You can find more information on this argument
[in the MDN documentation about JSON.parse](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse#Example.3A_Using_the_reviver_parameter).
##### strict
When set to `true`, will only accept arrays and objects; when `false` will
accept anything `JSON.parse` accepts. Defaults to `true`.
##### type
The `type` option is used to determine what media type the middleware will
parse. This option can be a string, array of strings, or a function. If not a
function, `type` option is passed directly to the
[type-is](https://www.npmjs.com/package/type-is#readme) library and this can
be an extension name (like `json`), a mime type (like `application/json`), or
a mime type with a wildcard (like `*/*` or `*/json`). If a function, the `type`
option is called as `fn(req)` and the request is parsed if it returns a truthy
value. Defaults to `application/json`.
##### verify
The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,
where `buf` is a `Buffer` of the raw request body and `encoding` is the
encoding of the request. The parsing can be aborted by throwing an error.
### bodyParser.raw([options])
Returns middleware that parses all bodies as a `Buffer` and only looks at
requests where the `Content-Type` header matches the `type` option. This
parser supports automatic inflation of `gzip`, `br` (brotli) and `deflate`
encodings.
A new `body` object containing the parsed data is populated on the `request`
object after the middleware (i.e. `req.body`). This will be a `Buffer` object
of the body.
#### Options
The `raw` function takes an optional `options` object that may contain any of
the following keys:
##### inflate
When set to `true`, then deflated (compressed) bodies will be inflated; when
`false`, deflated bodies are rejected. Defaults to `true`.
##### limit
Controls the maximum request body size. If this is a number, then the value
specifies the number of bytes; if it is a string, the value is passed to the
[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults
to `'100kb'`.
##### type
The `type` option is used to determine what media type the middleware will
parse. This option can be a string, array of strings, or a function.
If not a function, `type` option is passed directly to the
[type-is](https://www.npmjs.com/package/type-is#readme) library and this
can be an extension name (like `bin`), a mime type (like
`application/octet-stream`), or a mime type with a wildcard (like `*/*` or
`application/*`). If a function, the `type` option is called as `fn(req)`
and the request is parsed if it returns a truthy value. Defaults to
`application/octet-stream`.
##### verify
The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,
where `buf` is a `Buffer` of the raw request body and `encoding` is the
encoding of the request. The parsing can be aborted by throwing an error.
### bodyParser.text([options])
Returns middleware that parses all bodies as a string and only looks at
requests where the `Content-Type` header matches the `type` option. This
parser supports automatic inflation of `gzip`, `br` (brotli) and `deflate`
encodings.
A new `body` string containing the parsed data is populated on the `request`
object after the middleware (i.e. `req.body`). This will be a string of the
body.
#### Options
The `text` function takes an optional `options` object that may contain any of
the following keys:
##### defaultCharset
Specify the default character set for the text content if the charset is not
specified in the `Content-Type` header of the request. Defaults to `utf-8`.
##### inflate
When set to `true`, then deflated (compressed) bodies will be inflated; when
`false`, deflated bodies are rejected. Defaults to `true`.
##### limit
Controls the maximum request body size. If this is a number, then the value
specifies the number of bytes; if it is a string, the value is passed to the
[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults
to `'100kb'`.
##### type
The `type` option is used to determine what media type the middleware will
parse. This option can be a string, array of strings, or a function. If not
a function, `type` option is passed directly to the
[type-is](https://www.npmjs.com/package/type-is#readme) library and this can
be an extension name (like `txt`), a mime type (like `text/plain`), or a mime
type with a wildcard (like `*/*` or `text/*`). If a function, the `type`
option is called as `fn(req)` and the request is parsed if it returns a
truthy value. Defaults to `text/plain`.
##### verify
The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,
where `buf` is a `Buffer` of the raw request body and `encoding` is the
encoding of the request. The parsing can be aborted by throwing an error.
### bodyParser.urlencoded([options])
Returns middleware that only parses `urlencoded` bodies and only looks at
requests where the `Content-Type` header matches the `type` option. This
parser accepts only UTF-8 and ISO-8859-1 encodings of the body and supports
automatic inflation of `gzip`, `br` (brotli) and `deflate` encodings.
A new `body` object containing the parsed data is populated on the `request`
object after the middleware (i.e. `req.body`). This object will contain
key-value pairs, where the value can be a string or array (when `extended` is
`false`), or any type (when `extended` is `true`).
#### Options
The `urlencoded` function takes an optional `options` object that may contain
any of the following keys:
##### extended
The "extended" syntax allows for rich objects and arrays to be encoded into the
URL-encoded format, allowing for a JSON-like experience with URL-encoded. For
more information, please [see the qs
library](https://www.npmjs.com/package/qs#readme).
Defaults to `false`.
##### inflate
When set to `true`, then deflated (compressed) bodies will be inflated; when
`false`, deflated bodies are rejected. Defaults to `true`.
##### limit
Controls the maximum request body size. If this is a number, then the value
specifies the number of bytes; if it is a string, the value is passed to the
[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults
to `'100kb'`.
##### parameterLimit
The `parameterLimit` option controls the maximum number of parameters that
are allowed in the URL-encoded data. If a request contains more parameters
than this value, a 413 will be returned to the client. Defaults to `1000`.
##### type
The `type` option is used to determine what media type the middleware will
parse. This option can be a string, array of strings, or a function. If not
a function, `type` option is passed directly to the
[type-is](https://www.npmjs.com/package/type-is#readme) library and this can
be an extension name (like `urlencoded`), a mime type (like
`application/x-www-form-urlencoded`), or a mime type with a wildcard (like
`*/x-www-form-urlencoded`). If a function, the `type` option is called as
`fn(req)` and the request is parsed if it returns a truthy value. Defaults
to `application/x-www-form-urlencoded`.
##### verify
The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,
where `buf` is a `Buffer` of the raw request body and `encoding` is the
encoding of the request. The parsing can be aborted by throwing an error.
##### defaultCharset
The default charset to parse as, if not specified in content-type. Must be
either `utf-8` or `iso-8859-1`. Defaults to `utf-8`.
##### charsetSentinel
Whether to let the value of the `utf8` parameter take precedence as the charset
selector. It requires the form to contain a parameter named `utf8` with a value
of `✓`. Defaults to `false`.
##### interpretNumericEntities
Whether to decode numeric entities such as `&#9786;` when parsing an iso-8859-1
form. Defaults to `false`.
##### depth
The `depth` option is used to configure the maximum depth of the `qs` library when `extended` is `true`. This allows you to limit the amount of keys that are parsed and can be useful to prevent certain types of abuse. Defaults to `32`. It is recommended to keep this value as low as possible.
## Errors
The middlewares provided by this module create errors using the
[`http-errors` module](https://www.npmjs.com/package/http-errors). The errors
will typically have a `status`/`statusCode` property that contains the suggested
HTTP response code, an `expose` property to determine if the `message` property
should be displayed to the client, a `type` property to determine the type of
error without matching against the `message`, and a `body` property containing
the read body, if available.
The following are the common errors created, though any error can come through
for various reasons.
### content encoding unsupported
This error will occur when the request had a `Content-Encoding` header that
contained an encoding but the "inflation" option was set to `false`. The
`status` property is set to `415`, the `type` property is set to
`'encoding.unsupported'`, and the `charset` property will be set to the
encoding that is unsupported.
### entity parse failed
This error will occur when the request contained an entity that could not be
parsed by the middleware. The `status` property is set to `400`, the `type`
property is set to `'entity.parse.failed'`, and the `body` property is set to
the entity value that failed parsing.
### entity verify failed
This error will occur when the request contained an entity that could not be
failed verification by the defined `verify` option. The `status` property is
set to `403`, the `type` property is set to `'entity.verify.failed'`, and the
`body` property is set to the entity value that failed verification.
### request aborted
This error will occur when the request is aborted by the client before reading
the body has finished. The `received` property will be set to the number of
bytes received before the request was aborted and the `expected` property is
set to the number of expected bytes. The `status` property is set to `400`
and `type` property is set to `'request.aborted'`.
### request entity too large
This error will occur when the request body's size is larger than the "limit"
option. The `limit` property will be set to the byte limit and the `length`
property will be set to the request body's length. The `status` property is
set to `413` and the `type` property is set to `'entity.too.large'`.
### request size did not match content length
This error will occur when the request's length did not match the length from
the `Content-Length` header. This typically occurs when the request is malformed,
typically when the `Content-Length` header was calculated based on characters
instead of bytes. The `status` property is set to `400` and the `type` property
is set to `'request.size.invalid'`.
### stream encoding should not be set
This error will occur when something called the `req.setEncoding` method prior
to this middleware. This module operates directly on bytes only and you cannot
call `req.setEncoding` when using this module. The `status` property is set to
`500` and the `type` property is set to `'stream.encoding.set'`.
### stream is not readable
This error will occur when the request is no longer readable when this middleware
attempts to read it. This typically means something other than a middleware from
this module read the request body already and the middleware was also configured to
read the same request. The `status` property is set to `500` and the `type`
property is set to `'stream.not.readable'`.
### too many parameters
This error will occur when the content of the request exceeds the configured
`parameterLimit` for the `urlencoded` parser. The `status` property is set to
`413` and the `type` property is set to `'parameters.too.many'`.
### unsupported charset "BOGUS"
This error will occur when the request had a charset parameter in the
`Content-Type` header, but the `iconv-lite` module does not support it OR the
parser does not support it. The charset is contained in the message as well
as in the `charset` property. The `status` property is set to `415`, the
`type` property is set to `'charset.unsupported'`, and the `charset` property
is set to the charset that is unsupported.
### unsupported content encoding "bogus"
This error will occur when the request had a `Content-Encoding` header that
contained an unsupported encoding. The encoding is contained in the message
as well as in the `encoding` property. The `status` property is set to `415`,
the `type` property is set to `'encoding.unsupported'`, and the `encoding`
property is set to the encoding that is unsupported.
### The input exceeded the depth
This error occurs when using `bodyParser.urlencoded` with the `extended` property set to `true` and the input exceeds the configured `depth` option. The `status` property is set to `400`. It is recommended to review the `depth` option and evaluate if it requires a higher value. When the `depth` option is set to `32` (default value), the error will not be thrown.
## Examples
### Express/Connect top-level generic
This example demonstrates adding a generic JSON and URL-encoded parser as a
top-level middleware, which will parse the bodies of all incoming requests.
This is the simplest setup.
```js
const express = require('express')
const bodyParser = require('body-parser')
const app = express()
// parse application/x-www-form-urlencoded
app.use(bodyParser.urlencoded())
// parse application/json
app.use(bodyParser.json())
app.use(function (req, res) {
res.setHeader('Content-Type', 'text/plain')
res.write('you posted:\n')
res.end(String(JSON.stringify(req.body, null, 2)))
})
```
### Express route-specific
This example demonstrates adding body parsers specifically to the routes that
need them. In general, this is the most recommended way to use body-parser with
Express.
```js
const express = require('express')
const bodyParser = require('body-parser')
const app = express()
// create application/json parser
const jsonParser = bodyParser.json()
// create application/x-www-form-urlencoded parser
const urlencodedParser = bodyParser.urlencoded()
// POST /login gets urlencoded bodies
app.post('/login', urlencodedParser, function (req, res) {
if (!req.body || !req.body.username) res.sendStatus(400)
res.send('welcome, ' + req.body.username)
})
// POST /api/users gets JSON bodies
app.post('/api/users', jsonParser, function (req, res) {
if (!req.body) res.sendStatus(400)
// create user in req.body
})
```
### Change accepted type for parsers
All the parsers accept a `type` option which allows you to change the
`Content-Type` that the middleware will parse.
```js
const express = require('express')
const bodyParser = require('body-parser')
const app = express()
// parse various different custom JSON types as JSON
app.use(bodyParser.json({ type: 'application/*+json' }))
// parse some custom thing into a Buffer
app.use(bodyParser.raw({ type: 'application/vnd.custom-type' }))
// parse an HTML body into a string
app.use(bodyParser.text({ type: 'text/html' }))
```

# BSON parser
BSON is short for "Binary JSON," and is the binary-encoded serialization of JSON-like documents.
You can learn more about it in [the specification](http://bsonspec.org).
### Table of Contents
- [Usage](#usage)
- [Bugs/Feature Requests](#bugs--feature-requests)
- [Installation](#installation)
- [Documentation](#documentation)
- [FAQ](#faq)
### Release Integrity
Releases are created automatically and signed using the [Node team's GPG key](https://pgp.mongodb.com/node-driver.asc). This applies to the git tag as well as all release packages provided as part of a GitHub release. To verify the provided packages, download the key and import it using gpg:
```shell
gpg --import node-driver.asc
```
The GitHub release contains a detached signature file for the NPM package (named
`bson-X.Y.Z.tgz.sig`).
The following command returns the link npm package.
```shell
npm view bson@vX.Y.Z dist.tarball
```
Using the result of the above command, a `curl` command can return the official npm package for the release.
To verify the integrity of the downloaded package, run the following command:
```shell
gpg --verify bson-X.Y.Z.tgz.sig bson-X.Y.Z.tgz
```
>[!Note]
No verification is done when using npm to install the package. The contents of the Github tarball and npm's tarball are identical.
## Bugs / Feature Requests
Think you've found a bug? Want to see a new feature in `bson`? Please open a case in our issue management tool, JIRA:
1. Create an account and login: [jira.mongodb.org](https://jira.mongodb.org)
2. Navigate to the NODE project: [jira.mongodb.org/browse/NODE](https://jira.mongodb.org/browse/NODE)
3. Click **Create Issue** - Please provide as much information as possible about the issue and how to reproduce it.
Bug reports in JIRA for the NODE driver project are **public**.
## Usage
To build a new version perform the following operations:
```
npm install
npm run build
```
### Node.js or Bundling Usage
When using a bundler or Node.js you can import bson using the package name:
```js
import { BSON, EJSON, ObjectId } from 'bson';
// or:
// const { BSON, EJSON, ObjectId } = require('bson');
const bytes = BSON.serialize({ _id: new ObjectId() });
console.log(bytes);
const doc = BSON.deserialize(bytes);
console.log(EJSON.stringify(doc));
// {"_id":{"$oid":"..."}}
```
### Browser Usage
If you are working directly in the browser without a bundler please use the `.mjs` bundle like so:
```html
<script type="module">
import { BSON, EJSON, ObjectId } from './lib/bson.mjs';
const bytes = BSON.serialize({ _id: new ObjectId() });
console.log(bytes);
const doc = BSON.deserialize(bytes);
console.log(EJSON.stringify(doc));
// {"_id":{"$oid":"..."}}
</script>
```
## Installation
```sh
npm install bson
```
### MongoDB Node.js Driver Version Compatibility
Only the following version combinations with the [MongoDB Node.js Driver](https://github.com/mongodb/node-mongodb-native) are considered stable.
| | `bson@1.x` | `bson@4.x` | `bson@5.x` | `bson@6.x` | `bson@7.x` |

#### _EJSON_.parse(text, [options])
| Param | Type | Default | Description |
| ----------------- | -------------------- | ----------------- | ---------------------------------------------------------------------------------- |
| text | <code>string</code> | | |
| [options] | <code>object</code> | | Optional settings |
| [options.relaxed] | <code>boolean</code> | <code>true</code> | Attempt to return native JS types where possible, rather than BSON types (if true) |
Parse an Extended JSON string, constructing the JavaScript value or object described by that
string.
**Example**
```js
const { EJSON } = require('bson');
const text = '{ "int32": { "$numberInt": "10" } }';
// prints { int32: { [String: '10'] _bsontype: 'Int32', value: '10' } }
console.log(EJSON.parse(text, { relaxed: false }));
// prints { int32: 10 }
console.log(EJSON.parse(text));
```
<a name="EJSON.stringify"></a>
#### _EJSON_.stringify(value, [replacer], [space], [options])
| Param | Type | Default | Description |
| ----------------- | ------------------------------------------- | ----------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| value | <code>object</code> | | The value to convert to extended JSON |
| [replacer] | <code>function</code> \| <code>array</code> | | A function that alters the behavior of the stringification process, or an array of String and Number objects that serve as a whitelist for selecting/filtering the properties of the value object to be included in the JSON string. If this value is null or not provided, all properties of the object are included in the resulting JSON string |
| [space] | <code>string</code> \| <code>number</code> | | A String or Number object that's used to insert white space into the output JSON string for readability purposes. |
| [options] | <code>object</code> | | Optional settings |
| [options.relaxed] | <code>boolean</code> | <code>true</code> | Enabled Extended JSON's `relaxed` mode |
| [options.legacy] | <code>boolean</code> | <code>true</code> | Output in Extended JSON v1 |
Converts a BSON document to an Extended JSON string, optionally replacing values if a replacer
function is specified or optionally including only the specified properties if a replacer array
is specified.
**Example**
```js
const { EJSON } = require('bson');
const Int32 = require('mongodb').Int32;
const doc = { int32: new Int32(10) };
// prints '{"int32":{"$numberInt":"10"}}'
console.log(EJSON.stringify(doc, { relaxed: false }));
// prints '{"int32":10}'
console.log(EJSON.stringify(doc));
```
<a name="EJSON.serialize"></a>
#### _EJSON_.serialize(bson, [options])
| Param | Type | Description |
| --------- | ------------------- | ---------------------------------------------------- |
| bson | <code>object</code> | The object to serialize |
| [options] | <code>object</code> | Optional settings passed to the `stringify` function |
Serializes an object to an Extended JSON string, and reparse it as a JavaScript object.
<a name="EJSON.deserialize"></a>
#### _EJSON_.deserialize(ejson, [options])
| Param | Type | Description |
| --------- | ------------------- | -------------------------------------------- |
| ejson | <code>object</code> | The Extended JSON object to deserialize |
| [options] | <code>object</code> | Optional settings passed to the parse method |
Deserializes an Extended JSON object into a plain JavaScript object with native/BSON types
## Error Handling
It is our recommendation to use `BSONError.isBSONError()` checks on errors and to avoid relying on parsing `error.message` and `error.name` strings in your code. We guarantee `BSONError.isBSONError()` checks will pass according to semver guidelines, but errors may be sub-classed or their messages may change at any time, even patch releases, as we see fit to increase the helpfulness of the errors.
Any new errors we add to the driver will directly extend an existing error class and no existing error will be moved to a different parent class outside of a major release.
This means `BSONError.isBSONError()` will always be able to accurately capture the errors that our BSON library throws.
Hypothetical example: A collection in our Db has an issue with UTF-8 data:
```ts
let documentCount = 0;
const cursor = collection.find({}, { utf8Validation: true });
try {
for await (const doc of cursor) documentCount += 1;
} catch (error) {
if (BSONError.isBSONError(error)) {
console.log(`Found the troublemaker UTF-8!: ${documentCount} ${error.message}`);
return documentCount;
}
throw error;
}
```
## React Native
js-bson requires the `atob`, `btoa` and `TextEncoder` globals. Older versions of React Native did not support these global objects, and so
[js-bson v5.4.0](https://github.com/mongodb/js-bson/releases/tag/v5.4.0) added support for bundled polyfills for these globals. Newer versions
of Hermes includes these globals, and so the polyfills for are no longer needed in the js-bson package.
If you find yourself on a version of React Native that does not have these globals, either:
1. polyfill them yourself
2. upgrade to a later version of hermes
3. use a version of js-bson `>=5.4.0` and `<7.0.0`
One additional polyfill, `crypto.getRandomValues` is recommended and can be installed with the following command:
```sh
npm install --save react-native-get-random-values
```
The following snippet should be placed at the top of the entrypoint (by default this is the root `index.js` file) for React Native projects using the BSON library. These lines must be placed for any code that imports `BSON`.
```typescript
// Required Polyfills For ReactNative
import 'react-native-get-random-values';
```
Finally, import the `BSON` library like so:
```typescript
import { BSON, EJSON } from 'bson';
```
This will cause React Native to import the `node_modules/bson/lib/bson.rn.cjs` bundle (see the `"react-native"` setting we have in the `"exports"` section of our [package.json](./package.json).)
### Technical Note about React Native module import
The `"exports"` definition in our `package.json` will result in BSON's CommonJS bundle being imported in a React Native project instead of the ES module bundle. Importing the CommonJS bundle is necessary because BSON's ES module bundle of BSON uses top-level await, which is not supported syntax in [React Native's runtime hermes](https://hermesengine.dev/).
## FAQ
#### Why does `undefined` get converted to `null`?
The `undefined` BSON type has been [deprecated for many years](http://bsonspec.org/spec.html), so this library has dropped support for it. Use the `ignoreUndefined` option (for example, from the [driver](http://mongodb.github.io/node-mongodb-native/2.2/api/MongoClient.html#connect) ) to instead remove `undefined` keys.
#### How do I add custom serialization logic?
This library looks for `toBSON()` functions on every path, and calls the `toBSON()` function to get the value to serialize.
```javascript
const BSON = require('bson');
class CustomSerialize {
toBSON() {
return 42;
}
}
const obj = { answer: new CustomSerialize() };
// "{ answer: 42 }"
console.log(BSON.deserialize(BSON.serialize(obj)));
```
