rddx-express v0.0.1

rddx-express

Express.js base project for REPL drive development

Installation

For Node v4.0.0 or above:

$ npm install rddx-express express@4.x --save

Notes: rddx-express doesn't include express module, so you need to install it by youself.

Usage

Example files

launch file app.js:

'use strict';

const path = require('path');
const project = require('rddx-express');

// required options
project.set('path', __dirname);
project.set('port', 3000);

// development mode options
project.set('mod reload', true);         // enable hot reload
project.set('uncaught exception', true); // catch uncaughtException
project.set('repl', true);               // start a REPL

// register module
project.register('init', './init.js');
project.register('router.default', './routes/index.js');
project.register('router.admin', './routes/admin.js');

// events
project.on('reload', file => {
  console.log(`reload file: ${file}`);
});
project.on('init', app => {
  console.log(`inited`);
});

// start listening
project.listen(err => {
  console.log(`start failed: ${err}`);
});

init express file init.js (support hot reload):

'use strict';
const path = require('path');
const express = require('express');
const serveStatic = require('serve-static');
const ejs = require('ejs');

module.exports = function (project) {

  let app = express();

  app.set('views', path.resolve(__dirname, 'views'));
  app.set('view engine', 'html');
  app.engine('html', ejs.__express);
  app.use('/assets', serveStatic(path.resolve(__dirname, 'assets')));
  app.use('/admin', project.router('admin'));
  app.use('/', project.router('default'));

  // return an express instance
  return app;

};

register routes file routes/index.js (support hot reload):

'use strict';

module.exports = function (project, mod, router) {

  // register hot reload module
  mod.register('home', './home.js');
  mod.register('user', './user.js');

  router.get('/', mod('home').index);
  router.get('/list', mod('home').list);

  router.get('/user', mod('user').index);
  router.get('/signup', mod('user').signup);
  router.get('/login', mod('user').login);

};

routes handle file routes/home.js (support hot reload):

'use strict';

const project = require('rddx-express');

exports.index = function (req, res, next) {
  res.render('index');
};

exports.list = function (req, res, next) {
  res.render('list');
};

Start development

run app.js to start:

$ node app.js

Notes: when the (support hot reload) file has been changed, and option mod reload is set to true, will automatically reload it.

For file init.js, generally does not support hot reload. If you want to make some change, for example, register a new router:

first step, create a new file routes/admin.js (like above file routes/index.js);

the next, just type you register code in REPL:

[rddx-express]> project.register('router.admin', './routes/admin.js');

Notes: in REPL, you can use variable name $project to access the project instance.

Production deploy

delete the below lines in file app.js:

// development mod
project.set('mod reload', true);         // enable hot reload
project.set('uncaught exception', true); // catch uncaughtException
project.set('repl', true);               // start a REPL
