hapi-modularize

Helper for modular plugin based Hapi servers.

If your plugin is executed then it automatically starts a new server with the defined connections and server settings (with a generated glue manifest). If the plugin is required then it just exports the plugin (to be used in another server/connection).

Common use case

You create one repository/module/plugin with your browser-client application. Another one with your api. You can execute them independently or use them as plugins for a upper-level application.

Installation

npm install hapi-modularize

Usage

modularize(options, plugin);

Creates a new Plugin where:

• options - the configuration where:

  • attributes - a plugin properties object. See http://hapijs.com/api#plugins

  • pkg - alternatively, the attributes.name and attributes.version can be included via the pkg attribute containing the 'package.json' file for the module which already has the name and version included.

  • server - an object containing the options passed to new Server([options])

  • connections - an array of connection options, passed individually in calls to server.connection([options])

  • register - a plugin configuration object can have: * any option from server.register options * options - an object to use as the plugin options which get passed to the plugin's registration function when called.

  • relativeTo - a file-system path string that is used to resolve relative loading modules.

  • preConnections - a callback function that is called prior to adding connections to the server. The function signature is function (server, next) where:

  • server - is the server object returned from new Server(options).

  • next- the callback function the method must call to return control over to glue

  • prePlugins - a callback function that is called prior to registering plugins with the server. The function signature is function (server, next) where:

    • server - is the server object with all connections selected.
    • next- the callback function the method must call to return control over to glue

• plugin : a plugin is a function with the signature function(server, options, next) where:

  • server - the server object the plugin is being registered to.
  • options - an options object passed to the plugin during registration.
  • next - a callback method the function must call to return control back to the framework to complete the registration process with signature function(error) where:
    • error - any plugin registration error.

Examples

In this example, myApp will listen on port 80 and will have clientand api registered as plugins. But you can also execute client or api independently, and they will respectively listen on port 3000 and 3001.

/client/index.js

// ES6 syntax

/**
 * Import dependencies
 */
import pkg from './package.json';
import modularize from 'hapi-modularize';


/**
 * Connections configuration
 */
const connections = [
  {
    port: 3000, labels: [pkg.name]
  }
];


/**
 * Export plugin
 */
export default modularize({pkg, connections}, (server, options, next) => {

  // ... do something with your client plugin

  next();
});

/api/index.js

// ES6 syntax

/**
 * Import dependencies
 */
import modularize from 'hapi-modularize';


/**
 * Plugin attributes
 */
const attributes = {
  name: 'api',
  version: '1.0.0'
}


/**
 * Connections configuration
 */
const connections = [
  {
    port: 3001, labels: [attributes.name]
  }
];


/**
 * Export plugin
 */
export default modularize({attributes, connections}, (server, options, next) => {

  // ... do something with your api plugin

  next();
});

/production/myApp.js

var Glue = require('glue');

var manifest = {
  connections: [
    {
      port: 80,
      labels: [
        'myApp'
      ]
    }
  ],
  server: {
    // ... some server options
  },
  plugins: {
    '../../api/index.js': [{
     // ... some plugin configuration
    }],
    '../../client/index.js': [{}],

    // ... some production specific plugins
  }
}

Glue.compose(manifest, function (error, server) {
  if (error) {
    return console.error(error);
  }

  console.log('Server running at:', server.info.uri);
});
