Build status

 

Changelog

Prerequisites

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)

GitHub repository

https://github.com/readium/r2-lcp-js

There is no github.io site for this project (no gh-pages branch).

NPM package

https://www.npmjs.com/package/r2-lcp-js

Command line install:

npm install r2-lcp-js
OR
yarn add r2-lcp-js

...or manually add in your package.json:
``json
"dependencies": {
"r2-lcp-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-lcp-js/dist/

(alternatively, GitHub mirror with semantic-versioning release tags: https://github.com/edrlab/r2-lcp-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-lcp-js/dist/*, so this package can be used directly in a TypeScript project.

Example usage:

`javascript
// currently no index file
// import { * } from "r2-lcp-js";

// ES5 import (assuming node_modules/r2-lcp-js/):
import { downloadEPUBFromLCPL } from "r2-lcp-js/dist/es5/src/publication-download";

// ... or alternatively using a convenient path alias in the TypeScript config (+ WebPack etc.):
import { downloadEPUBFromLCPL } from "@r2-lcp-js/publication-download";
`

Dependencies

https://david-dm.org/readium/r2-lcp-js

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.

Version(s), Git revision(s)

NPM package (latest published):

https://unpkg.com/r2-lcp-js/dist/gitrev.json

Alternatively, GitHub mirror with semantic-versioning release tags:

https://raw.githack.com/edrlab/r2-lcp-js-dist/develop/dist/gitrev.json

Developer quick start

Command line steps (NPM, but similar with YARN):

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