About Mason

Mason is a modular command line toolkit written in ES6 with promises.

Installation

For command line usage, install Mason globally: npm i -g mason.cli

Configuration

You can load additional plugins with Mason by creating a mason.config.js file in your project directory.

Example Configuration:

mason.config.js

module.exports = function(Mason) {
	Mason.registerCommand('test', function(input, config, Mason, resolve, reject) {
        Mason.spawn(`${__dirname}/node_modules/.bin/jest`);
	});

	return {
  		plugins: ['mason.plugin.scaffold', './path/to/LocalPlugin']
	};
};

Now with support for Babel!

mason.babel.js

export default (Mason) => {
    Mason.registerCommand('test', (input, config, Mason, resolve, reject) => {
        Mason.spawn(`${__dirname}/node_modules/.bin/jest`);
    });
};

In this example, mason.plugin.scaffold is a package installed from NPM and './path/to/LocalPlugin' is the path of a local js module.

Usage

By default, Mason currently comes with only two commands: version and help. As we learned above, Mason does support plugins. Plugins can extend Mason and introduce additional commands.

Authoring a Plugin

An example of plugin support can be found in the mason-scaffold repository
