JS Utilities Library

Library that contains all sharable utilities and configuration files, written in Javascript


yarn add @2600hz/js-utilities


import { capitalize, humanize } from '@2600hz/js-utilities';

// ...

<Button title={humanize(buttonName)} onPress={}.... />

You can also import or require directly from folder

const {
} = require('@2600hz/js-utilities/lib/prettier-config');

prettierBaseConfig.jsxBracketSameLine = false;

module.exports = prettierBaseConfig;

Configuration files You can extend any of the following configs:

  • eslint (.eslintrc.js)
  • prettier (..prettierrc.js)
  • release-it (.release-it.js)
  • commitlint (commitlint.config.js)
  • svgrrc (.svgrrc.js)
  • jest (jest.config.js)
  • lint-staged (lint-staged.config.js)
  • tsconfig (tsconfig.json)

All configuration files are imported and used same way, there are just two files that need different treatment

eslint Eslint file exports a function that receives the root folder

const {
} = require('@2600hz/js-utilities/lib/eslint-config');

module.exports = eslintBaseConfig(__dirname);

tsconfig This file must extends from any of the ts config files available

  "extends": "@2600hz/js-utilities/tsconfig.base",
  "compilerOptions": {
    "baseUrl": "./",
  "exclude": [...],
  "include": [...],

Commits Commits must follow conventional commit format Make sure your messages look like the following examples

feat: Adding new badge component
fix: Touchable component not being exported correctly
fix!: Drop support for Typescript

Note that the last one will generate a Major commit. It has the same result as adding a breaking change footer

Follow Semantic Versioning 2.0.0 to update project version.

Release-It will take care of versioning, you just have to give the correct type to commit:

  • fix - to indicate a bug fix (PATCH) ex . v0.0.1
  • feat - to indicate a new feature (MINOR) ex. v0.1.0
  • chore - for updates that do not require a version bump (.gitignore, comments, etc.)
  • docs - for updates to the documentation
  • BREAKING CHANGE - regardless of type, indicates a Major release (MAJOR) ex. v1.0.0
