Training material for developers of the Metal.js library.
These documents were originally created as written material closely following the contents of a live training. They should be helpful as a source where people can go to for information they've missed or forgotten, or even for new developers to familiarize themselves with the codebase without watching the training.
Just keep in mind that this can easily become outdated, as it references parts of the code that may change with time.
The material presented here should help developers get more familiar with how Metal.js works internally. It will cover the main repositories in the metal github org.
The most important of all these is metal/metal.js, as it contains the library's core modules around which all the others were built.
These are just some suggestions that can be helpful when following this training, but they're all optional.
Before starting, follow these instructions to setup a local playground you can use to run and debug the code as you learn how it works:
- Clone this repo on your machine.
- Install npm dependencies:
npm install. - Run the watch script:
npm run watch. - Use the file at playground/main.js to play with the Metal.js modules in ES6. The watch script will automatically rebuild it for you whenever it changes. All main modules are already included in this repo's package.json, but feel free to install any others you also want to use.
- Open playground/index.html in your browser to run your code.
Every now and then you'll find some links to debug examples. These will point
you to files inside the playground folder with some examples you can use to
run the code we're explaining with a debugger. If you want to use them you can
either copy the code to playground/main.js or change
webpack.config.js to point to it instead, and then rebuild
with npm run build.
This material will constantly reference links to jsfiddle that you can open to see some helpful examples working. You can alter these as you like on your side to test other use cases, or even copy them to your playground if you wish to have more control. You can see a list of all available fiddles here.
