Codec Interface

This is the primary interface for implementing new codecs.

The interface is quite simple:

{
  encode: Function,
  decode: Function,
  codec: String,
  reader: Function
}

encode & decode

These are the primary methods you need to implement in order to implement a new codec.

While you can implement the entire Reader interface yourself, you can actually leverage our codec-interface.create utility to get a full implementation with these methods alone.

• encode takes a native JavaScript object and returns a binary encoding.
• decode takes a binary encoding and returns a nativfe JavaScript object.

Methods can be either synchronous or asynchronous (returns a promise).

reader(block)

The reader function accepts a Block instance and returns a full Reader interface.

This method can be either synchronous or asynchronous (returns a promise).

codec-interface.create(encode, decode, codecName)

Returns a full Codec Interface based on your encode and decode implementations.

Reader()

Reader.get(path)

Reader.links()

Reader.tree()
