ramda-adjunct

What is ramda-adjunct?

Ramda-adjunct is a community-maintained extension of the Ramda library, providing additional utility functions that complement Ramda's core functionality. It offers a wide range of functions for data manipulation, validation, and functional programming.

What are ramda-adjunct's main functionalities?

Data Manipulation

The `partitionIndexed` function splits a list into two lists based on a predicate function that takes both the value and the index. This is useful for more complex partitioning logic.

const RA = require('ramda-adjunct');
const R = require('ramda');

const data = [1, 2, 3, 4, 5];
const result = RA.partitionIndexed((val, idx) => idx % 2 === 0, data);
console.log(result); // [[1, 3, 5], [2, 4]]

Validation

The `isNotNilOrEmpty` function checks if a value is neither null nor an empty string, array, or object. This is useful for validation checks in your application.

const RA = require('ramda-adjunct');

const isValid = RA.isNotNilOrEmpty('Hello');
console.log(isValid); // true

Functional Programming

The `curryN` function allows you to curry a function with a specified arity. This is useful for creating more flexible and reusable functions.

const RA = require('ramda-adjunct');
const R = require('ramda');

const add = (a, b, c) => a + b + c;
const curriedAdd = RA.curryN(3, add);
console.log(curriedAdd(1)(2)(3)); // 6

Other packages similar to ramda-adjunct

lodash

Lodash is a popular utility library that provides a wide range of functions for data manipulation, validation, and functional programming. It is more widely used and has a larger community compared to ramda-adjunct.

underscore

Underscore is another utility library similar to Lodash, offering a variety of functions for data manipulation and functional programming. It is older and less feature-rich compared to Lodash but still widely used.

ramda

Ramda is the core library that ramda-adjunct extends. It focuses on functional programming and immutability, providing a set of utility functions for working with data in a functional style.

README

Ramda Adjunct

This library is a community maintained extension of Ramda.

Support us

Although we love working on ramda-adjunct, we must invest our free time to make this library great. Support this project's evolution via Open Collective.

Motivation

It seems to be very common for people to create their own utils and recipes composing the Ramda functions and creating yet more complex aggregate functions. Ramda Adjunct tries to eliminate this repetitive wheel of reinvention and centralize most aggregate utils in its codebase.

Benefits

As a maintainers, we see three main benefits in Ramda Adjunct.

Centralization

All Ramda recipes and aggregate utils not present in Ramda are centralized here. There is no more need for everybody to create their own utils in their own codebases.

Tests

Creating custom aggregate utils or implementing recipes from Ramda wiki creates the defectiveness problem. The problem is caused by the absence of any tests. Ramda Adjunct keeps 100% code coverage and mimics the Ramda test patterns.

Impeccable documentation

You cannot call a library great without a great documentation. Ramda Adjnuct generates its documentation directly from its codebase and uses patterns both found in Ramda and Lodash to document its API.

Requirements

• ramda >= 0.19.0
• node >= 0.10.48

Ramda Adjunct is being automatically tested against node version >=6 <=9.

Legacy builds

We are building our npm distributions by Webpack to support also legacy versions of node starting from 0.10.48. Although all tests are run only against node version >=4 <=8, we rely on Webpack to transpile ramda-adjunct into legacy ES5. It is also possible that our ES5 distributions run on node versions older than 0.10.48 as long as they support ES5.

Installation

 $ npm i ramda-adjunct

Development

If you want to contribute to this project, please consult the CONTRIBUTING.md guideline.

Obtaining project copy

 $ git clone https://github.com/char0n/ramda-adjunct
 $ npm i

Running tests

 $ npm run test

Running linter

 $ npm run lint

Builds

 $ npm run build:es

If you use bundler that supports tree shaking and ES2015 imports. package.json is automatically pre-configured to tell ES2015 import to import from this directory.

es/* - ES5 code containing ES2015 imports

 $ npm run build:commonjs

If you use node to import ramda-adjunct. package.json is automatically pre-configured to tell require to import from this directory.

lib/* - ES5 code containing commonjs imports

 $ npm run build:umd

The command will create three types of bundles.

dist/RA.node.js - ES5 compliant bundle, running on all node versions

dist/RA.web.js - ES5 compliant bundle, running in browsers. Requires ramda.js to be required before

dist/RA.web.standalone.js - ES5 compliant bundle, running in browsers. It has ramda.js pre-bundled

You can always find fresh build files in circle-ci artifacts.

Usage

Web browser

<script src="ramda.js"></script>
<script src="RA.web.js"></script>

or

<script src="RA.web.standalone.js"></script>

Including Ramda Adjunct into HTML document exposes global variable RA on window object.

RA.isArray([]);

Node

const RA = require('ramda-adjunct');

RA.isArray([]);

or

const { isArray } = require('ramda-adjunct');

isArray([]);

Tree shaking support

Tree shaking is a term commonly used in the JavaScript context for dead-code elimination. It relies on the static structure of ES2015 module syntax, i.e. import and export. Ramda Adjunct natively supports tree shaking thanks to the way the code is organized and the fact that it is using ES2015 imports.

  import * as RA from 'ramda-adjunct';

  RA.isArray([]); //=> true

  import { isArray } from 'ramda-adjunct';

  isArray([]); //=> true

These two statements are equivalent and only isArray util should be incorporated into your bundle, not entire Ramda Adjunct.

Assimilated libraries

Typescript support

Although Ramda Adjunct is written in ES2016, we support Typescript. When Ramda Adjunct gets imported into Typescript project, typings are automatically imported and used.
