transform-data

Set of functions to build algorithmic transformations for data structures.

Small attempt of mine to make transformations of data structures simplier.

Installation

I assume that you use node.js or any bundling system with commonJs module support. To install it simply run the command below:

npm install transform-data

Usage

Current module exports function to apply transformations to the complex data structures and also contains helpers to build transformations easier.

All the helpers are provided with the lib/tool module.

transform(xf, f, col)

Arguments:

• xf(val, keypath, isCollection) — function which is used to apply transformation.
• f(val, keypath, isCollection) - function which is used to reduce the resulting collection.
• col (array|object) - the collection itself.

Example:

const { constant, identity } = require('lodash/fp');
const transform = require('transform-data');

// returns a deep copy of provided data structure
transform(identity, constant(true), {a: {b: 5}}); // {a: {b: 5}}

const { split } = require('transform-data/lib/tool');
const inc = a => a + 1;
const isOdd = a => a % 2 !== 0;

transform(split(inc), isOdd, [0, 1, 2, 3]); // [2, 4]

lib/tool module

Helpers:

• constant (funciton)
• curry (funciton)
• identity (funciton)
• isArray (funciton)
• isCollection (funciton)
• isFunction (funciton)
• isNumber (funciton)
• isObjectLike (funciton)
• isPlainObject (funciton)
• isString (funciton)
• isUndefined (funciton)
• split(primitive, collection = identity)
• toString (funciton)
