Encoder

A highly extensible encoding library built on top of the @basd/codex package. It provides a convenient way to define models and their associated fields allowing users to easily encode and decode data structures using different encoding schemes such as Base58 and foreign fields.

Features

• Custom Field Types: Supports different field types including base58 and foreign.
• Flexible Models: Define and use models easily to work with complex data structures.
• Encoding and Decoding: Provides simple and efficient encoding and decoding capabilities.
• Foreign Field Encoding: Seamlessly encode and decode foreign fields linked to other models.
• Bs58 Encoding: Out-of-the-box support for Base58 encoding and decoding.

Installation

Install the package with:

npm install @basd/encoder

Usage

First, import the Encoder library.

import Encoder from '@basd/encoder'

or

const Encoder = require('@basd/encoder')

Use the Encoder:

// Define models in the constructor
const encoder = new Encoder({ someType: { someField: 'string' }})

// Define a model by adding it
encoder.addModel('myModelType', { someField: 'string' })
// or
encoder.addModel('myModelType', { fields: { someField: 'string' }})

// Encode the data
const encodedData = encoder.encode('myModelType', data)

// Decode the data
const decodedData = encoder.decode('myModelType', encodedData)

Advanced Usage

Here's an example of using a foreign field to reference another model:

const models = {
  user: { name: 'string', age: 'number' },
  post: { title: 'string', body: 'string', author: 'user' },
}
const encoder = new Encoder(models, opts)
let data = { name: 'Alice', age: 33 }
let user = encoder.create('user', data)
let content = { title: 'Hello', body: 'World', author: user }
let post = encoder.create('post', content)

let encoded = encoder.encode('post', post)
let decoded = encoder.decode('post', encoded)

Classes

Base58Field

This class extends the string field type and provides encoding and decoding capabilities specific to the Base58 format.

EncoderForeignField

The EncoderForeignField class extends the Codex's foreign field type to provide specific encoding and decoding functionality for foreign types.

EncoderModel

The EncoderModel class provides methods for encoding and decoding a complete model by iterating through the defined fields.

Encoder

The Encoder class is the main interface for working with models, defining encoding, and decoding methods based on the schema and options provided.

Tests

In order to run the test suite, simply clone the repository and install its dependencies:

git clone https://gitlab.com/frenware/utils/encoder.git
cd encoder
npm install

To run the tests:
