core-stack

Create an object implementing:

• An event emitter (Evemit, only 1 kb).
• A plugin system that handles the asynchronous loading.
• A stack handler.
• And some useful methods for handling a core and config object.

core-stack was implemented with performance and lightness in mind.

Install

npm install core-stack

or with Yarn:

yarn add core-stack

Usage

See the source code for the JS doc.

Create a core

import CoreStack from 'core-stack';

// or const CoreStack = require('core-stack');
const core = new CoreStack();

// adds what do you need in the `core`...
core.foo = {};
core.bar = 'bar';

export default core;
// or module.exports = core;

Plugins

Create a plugin

/**
 * My plugin
 *
 * @param  {CoreStack}   core
 * @param  {*}           [args]
 * @param  {function}    done
 */
export default function myPlugin(core, args, done) {
  // add some feature to the core
  // ...

  // `done` function indicate that the plugin is loaded
  done(args);
};

Use a plugin

On the fly:

core.use(plugin, pluginArgs, function(done /*, doneArgs */) {
  console.log('plugin loaded!');
  done(/* doneArgs */);
});

or a reusable plugin:

import myPlugin from './plug/myPlugin';

core.use(myPlugin);
// or core.use(require('./plug/myPlugin'));

Example, create a simple logger plugin (reusable):

export default function loggerPlugin(core, args, done) {
  core.log = function() {
    console.log(...arguments);
  };

  core.logWarn = function() {
    console.warn(...arguments);
  };

  core.logError = function() {
    console.error(...arguments);
  };

  done();
};

Load and use the logger plugin:

import logger from './plug/logger';

// load the logger plugin
core.use(logger);

// use the logger plugin when the core was booted
core.boot(function() {
  core.log('Hello');
  core.logWarn('Warning!');
  core.logError('Ooops! An error occurred.');
})

Full example

import CoreStack from 'core-stack';

// Plugins
import logger from './plug/logger/';
import config from './plug/config/';
import router from './plug/router/';
import react from './plug/react/'; // or another lib / framework to initialize

const app = new CoreStack();

app
  .use(logger)
  .use(config)
  .use(router)
  .use(react)
  .boot(function() {
    app.log('all plugins are loaded');

    // you can emit any events with the builtin event emitter
    // see evemit package
    app.emit('app.booted');

    // init the routes and a router (e.g: routux package)
    router.init();
  })
;
