1) https://nodejs.org NodeJS >= 8, NPM >= 5 (check with command line node --version and npm --version)
2) OPTIONAL: https://yarnpkg.com Yarn >= 1.0 (check with command line yarn --version)

There is no github.io site for this project (no gh-pages branch).
https://www.npmjs.com/package/r2-utils-js
Command line install:
npm install r2-utils-js
ORyarn add r2-utils-js
...or manually add in your package.json:
``json`
"dependencies": {
"r2-utils-js": "latest"
}
The JavaScript code distributed in the NPM package is usable as-is (no transpilation required), as it is automatically-generated from the TypeScript source.
Several ECMAScript flavours are provided out-of-the-box: ES5, ES6-2015, ES7-2016, ES8-2017:
https://unpkg.com/r2-utils-js/dist/
(alternatively, GitHub mirror with semantic-versioning release tags: https://github.com/edrlab/r2-utils-js-dist/tree/develop/dist/ )
The JavaScript code is not bundled, and it uses require() statement for imports (NodeJS style).
More information about NodeJS compatibility:
http://node.green
Note that web-browser Javascript is currently not supported (only NodeJS runtimes).
The type definitions (aka "typings") are included as .d.ts files in ./node_modules/r2-utils-js/dist/*, so this package can be used directly in a TypeScript project.
Example usage:
`javascript
// currently no index file
// import { * } from "r2-utils-js";
// ES5 import (assuming node_modules/r2-utils-js/):
import { sortObject } from "r2-utils-js/dist/es5/src/_utils/JsonUtils";
// ... or alternatively using a convenient path alias in the TypeScript config (+ WebPack etc.):
import { sortObject } from "@r2-utils-js/JsonUtils";

A package-lock.json is provided (modern NPM replacement for npm-shrinkwrap.json).
A yarn.lock file is currently not provided at the root of the source tree.

NPM package (latest published):

Alternatively, GitHub mirror with semantic-versioning release tags:

Command line steps (NPM, but similar with YARN):
1) cd r2-utils-jsgit status
2) (please ensure there are no local changes, especially in package-lock.json and the dependency versions in package.json)rm -rf node_modules
3) (to start from a clean slate)npm install
4) , or alternatively npm ci (both commands initialize the node_modules tree of package dependencies, based on the strict package-lock.json definition)npm run build:all
5) (invoke the main build script: clean, lint, compile)ls dist` (that's the build output which gets published as NPM package)
6)
