Andrew e3b049cefd Chore(scripts): Remove jake dependency and use NPM scripts instead (#5828 )

* run `docs` via npm

* add shebang line to integrity.js, so npm will resolve node binary automatically

* remove unnecessary build-jake npm script

* add test.js script as replacement of Jakefile.js

* remove Jakefile, remove jake from devDependencies

* update docs

* move scripts to separate directory

* change shebang line from nodejs to js

* change shebang line from js to node

* update docs

* use Karma cli instead of custom test script

* add pretest and test-nolint scripts, remove lint scripts from travis.ci

Run linting scripts in pretest script, this way test script will automatically trigger code linting.

Add test-nolint script to have possibility to run tests without triggering pretest script with linting. This is useful when running tests in different browsers and tere's no sense to lint code more than one time

* replace shebang lines with node executable in npm scripts

* remove note about nodejs symlink in CONTRIBUTING.md

Using a Hosted Version of Leaflet

The latest stable Leaflet release is available on several CDN's — to start using it straight away, place this in the head of your HTML code:

<link rel="stylesheet" href="https://unpkg.com/leaflet@{{ site.latest_leaflet_version}}/dist/leaflet.css" />
<script src="https://unpkg.com/leaflet@{{ site.latest_leaflet_version}}/dist/leaflet.js"></script>

To avoid potential security problems, we recommend and encourage enabling subresource integrity when using Leaflet from a CDN:

<link rel="stylesheet" href="https://unpkg.com/leaflet@{{ site.latest_leaflet_version}}/dist/leaflet.css"
  integrity="{{site.integrity_hash_css}}"
  crossorigin=""/>
<script src="https://unpkg.com/leaflet@{{ site.latest_leaflet_version}}/dist/leaflet.js"
  integrity="{{site.integrity_hash_uglified}}"
  crossorigin=""></script>

Leaflet is available on the following free CDN's: unpkg, cdnjs, jsDelivr

Disclaimer: these services are external to Leaflet; for questions or support, please contact them directly.

Using a Downloaded Version of Leaflet

Inside the archives downloaded from the above links, you will see four things:

leaflet.js - This is the minified Leaflet JavaScript code.
leaflet-src.js - This is the readable, unminified Leaflet JavaScript, which is sometimes helpful for debugging. (The integrity hash for this file is {{site.integrity_hash_source}})
leaflet.css - This is the stylesheet for Leaflet.
images - This is a folder that contains images referenced by leaflet.css. It must be in the same directory as leaflet.css.

Unzip the downloaded archive to your website's directory and add this to the head of your HTML code:

<link rel="stylesheet" href="/path/to/leaflet.css" />
<script src="/path/to/leaflet.js"></script>

Using a JavaScript package manager

If you use the npm package manager, you can fetch a local copy of Leaflet by running:

npm install leaflet

You will find a copy of the Leaflet release files in node_modules/leaflet/dist.

Leaflet Source Code

These download packages above only contain the library itself. If you want to download the full source code, including unit tests, files for debugging, build scripts, etc., you can download it from the GitHub repository.

Building Leaflet from the Source

Leaflet build system is powered by the Node.js platform, which installs easily and works well across all major platforms. Here are the steps to set it up:

Download and install Node
Run the following command in the command line:

npm install

Now that you have everything installed, run npm run build inside the Leaflet directory. This will combine and compress the Leaflet source files, saving the build to the dist folder.
