Data Transformer

The Data Transformer library converts your payload to its minified/magnified form by converting the keys

Installation

Use the package manager npm.

npm i @cubic-wing/data-transformer

Usage

Generate a dictionary

const transformer = require("@cubic-wing/data-transformer")

const data = {
  very_long_word: 'very_long_word',
  longer_word: 'very_long_word',
  object_foo: { foo: 'foo', bar: 'bar' },
  array_foo: [ 'foo', 'bar' ],
  object_array_foo: [ { foo: 'foo', bar: 'bar' }, { foo: 'foo', bar: 'bar' } ]
}

const dictionary = transformer.generateDictionary(data);

// This will return the following
{
  very_long_word: 'vlw',
  longer_word: 'lw',
  foo: 'f',
  bar: 'b',
  object_foo: 'of',
  array_foo: 'af',
  object_array_foo: 'oaf'
}

Minify Data

const transformer = require("@cubic-wing/data-transformer")

const data = {
  very_long_word: 'very_long_word',
  longer_word: 'very_long_word',
  object_foo: { foo: 'foo', bar: 'bar' },
  array_foo: [ 'foo', 'bar' ],
  object_array_foo: [ { foo: 'foo', bar: 'bar' }, { foo: 'foo', bar: 'bar' } ]
}

const dictionary = {
  very_long_word: 'vlw',
  longer_word: 'lw',
  foo: 'f',
  bar: 'b',
  object_foo: 'of',
  array_foo: 'af',
  object_array_foo: 'oaf'
}

const minified = transformer.minify(data, dictionary)

// This will return the following
{
  vlw: 'very_long_word',
  lw: 'very_long_word',
  of: { f: 'foo', b: 'bar' },
  af: [ 'foo', 'bar' ],
  oaf: [ { f: 'foo', b: 'bar' }, { f: 'foo', b: 'bar' } ]
}

Magnify Data

const transformer = require("@cubic-wing/data-transformer")

const data = {
  vlw: 'very_long_word',
  lw: 'very_long_word',
  of: { f: 'foo', b: 'bar' },
  af: [ 'foo', 'bar' ],
  oaf: [ { f: 'foo', b: 'bar' }, { f: 'foo', b: 'bar' } ]
}

const dictionary = {
  very_long_word: 'vlw',
  longer_word: 'lw',
  foo: 'f',
  bar: 'b',
  object_foo: 'of',
  array_foo: 'af',
  object_array_foo: 'oaf'
}

const magnified= transformer.minify(data, dictionary)

// This will return the following
{
  very_long_word: 'very_long_word',
  longer_word: 'very_long_word',
  object_foo: { foo: 'foo', bar: 'bar' },
  array_foo: [ 'foo', 'bar' ],
  object_array_foo: [ { foo: 'foo', bar: 'bar' }, { foo: 'foo', bar: 'bar' } ]
}
