The [`Buffer`](https://nodejs.org/api/buffer.html#buffer_buffer) class in Node.js is used to represent binary data. JSON does not specify a way to encode binary data, so the Node.js implementation of `JSON.stringify` represents buffers as an object of shape `{ type: "Buffer", data: [<bytes as numbers>] }`. Unfortunately, `JSON.parse` does not turn this structure back into a `Buffer` object:
```
$ node
> JSON.parse(JSON.stringify({ buf: Buffer.from('hello world') }))
{ buf:
{ type: 'Buffer',
data: [ 104, 101, 108, 108, 111, 32, 119, 111, 114, 108, 100 ] } }
```
`JSON.stringify` and `JSON.parse` accept arguments called [`replacer`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify#The_replacer_parameter) and [`reviver`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse#Using_the_reviver_parameter) respectively which allow customizing the parsing/encoding behavior. This module provides a replacer which encodes Buffer data as a base64-encoded string, and a reviver which turns JSON objects which contain buffer-like data (either as arrays of numbers or strings) into `Buffer` instances. All other types of values are parsed/encoded as normal.
## API
### `stringify(value[, space])`
Convenience wrapper for [`JSON.stringify`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify) with the `replacer` described below.
### `parse(text)`
Convenience wrapper for [`JSON.parse`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse) with the `reviver` described below.
### `replacer(key, value)`
A [`replacer`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify#The_replacer_parameter) implementation which turns every value that is a `Buffer` instance into an object of shape `{ type: 'Buffer', data: 'base64:<base64-encoded buffer content>' }`. Empty buffers are encoded as `{ type: 'Buffer', data: '' }`.
### `reviver(key, value)`
A [`reviver`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse#Using_the_reviver_parameter) implementation which turns every object of shape `{ type: 'Buffer', data: <array of numbers or string> }` into a `Buffer` instance.
