codecs

codecs

Create an binary encoder/decoder for Node's build in types like, json, utf-8, hex.

npm install codecs

Useful to support value encodings similar to leveldb's.

Usage

const codecs = require('codecs')
const json = codecs('json')

console.log(json.encode({ hello: 'world' })) // Buffer.from('{"hello":"world"}')
console.log(json.decode(new Buffer('{"hello":"world"}'))) // { hello: 'world' }

API

const codec = codecs(type, [fallback])

Create a new codec.

Supported types are

• utf8
• json
• ndjson
• binary
• hex
• ascii
• base64
• ucs2
• ucs-2
• utf16le
• utf-16le
• binary

If an unknown type is passed-in, the fallback is used if given, else binary. If you want to use a custom codec you can pass in an object containing a an encode and decode method and that will be returned. If you pass a compact encoder, then it will be converted into a codec for you and returned.

const buf = codec.encode(value)

Encode a value to a buffer.

const value = codec.decode(buf)

Decode a buffer to a value.
