JSR Working Group Kicks Off with Ambitious Roadmap and Plans for Open Governance
At its inaugural meeting, the JSR Working Group outlined plans for an open governance model and a roadmap to enhance JavaScript package management.
Encode and parse data in the Concise Binary Object Representation (CBOR) data format (RFC7049).
Assimilate all your JavaScript objects into the Concise Binary Object Representation (CBOR) data format (RFC7049) as fast as possible.
This library is a fork of the awesome node-cbor. It borrows a lot of the interface, but drops all streaming and async processing in favor of a minimal syn api and being as fast as possible.
$ npm install --save borc
TODO
const cbor = require('borc')
const assert = require('assert')
const encoded = cbor.encode(true) // returns <Buffer f5>
const decoded = cbor.decodeFirst(encoded)
// decoded is the unpacked object
assert.ok(decoded === true)
// Use integers as keys
var m = new Map()
m.set(1, 2)
encoded = cbor.encode(m) // <Buffer a1 01 02>
See https://dignifiedquire.github.io/borc for details
The sync encoding and decoding are exported as a
leveldb encoding, as
cbor.leveldb
.
The following types are supported for encoding:
Decoding supports the above types, including the following CBOR tag numbers:
Tag | Generated Type |
---|---|
0 | Date |
1 | Date |
2 | bignumber |
3 | bignumber |
4 | bignumber |
5 | bignumber |
32 | url.URL |
35 | RegExp |
Borc supports custom tags as well as custom input types.
class MyType {
constructor (val) {
this.val = val
}
// Gets called when encoding this object
// gen - instance of the encoder
// obj - the object being encoded
//
// should return true on success and false otherwise
encodeCBOR (gen) {
return gen.pushAny('mytype:' + this.val)
}
}
cbor.encode([new MyType('hello')])
cbor.encode([new cbor.Tagged(42, 'hello')])
const decoder = new cbor.Decoder({
tags: {
42: (val) => val + ' world'
}
})
