express-play

Express based MVC Framework for Node.js

This project is under construction. Don't use it yet.

File Structure Based

The default file structure and the entry file of an express-play application:

/app
  /controllers     - controllers root directory
    /contents      - controllers sub directory
      articles.js  - articles controller (/contents/articles/... auto-loaded)
    accounts.js    - account controller (/accounts/... auto-loaded)
    home.js        - home controller (/home/... auto-loaded)
  /lib             - modules root directory
    logger.js      - logger module (auto-loaded and auto-injected)
    repository.js  - repository module (auto-loaded and auto-injected)
server.js

// server.js
// Super simple, isn't it?
require('express-play').play(3000);

The HTTP Request Handler Routing

The framework maps resource handler routings automatically using the object graph, function names and 'id' parameter that is special in express-play.

// /app/controllers/contents/articles.js
function ArticlesController() {
  // GET /contents/articles
  // GET /contents/articles/:id
  this.get = function (id) {
  };

  // POST /contents/articles
  this.post = function () {
  };

  this.comments = {
    // GET /contents/articles/comments
    // GET /contents/articles/comments/:id
    get: function (id) {
    },
    
    // POST /contents/articles/comments
    post: function () {
    }
  };

  // GET /contents/articles/top
  this.top = function () {
  };
}

module.exports = ArticlesController;

Query as Parameters

Query values are injected to the handler function as parameters automatically. The order of parameters is not important.

// /app/controllers/contents/articles.js
function ArticlesController() {
  // GET /contents/articles/top?by=[by]&count=[count]
  this.top = function (by, count) {
    by = by || 'likes';
    count = count || 10;
  };
}

module.exports = ArticlesController;

Dependency Injection

An object module:

// /app/lib/logger.js
function Logger() {
}

// The module name is 'logger' that is inferred from the file name.
module.exports = new Logger();

A constructor module:

// app/lib/repository.js
function Repository() {
}

// The module name is 'Repository' that is the constructor function name.
module.exports = Repository;

Injection to Controllers

// /app/controllers/contents/articles.js
function ArticlesController(logger) {
  // 'logger' is injected to this controller once.
  this.logger = logger;
}

module.exports = ArticlesController;

Injection to Handler Functions

// /app/controllers/contents/articles.js
function ArticlesController() {
  // GET /contents/articles/top
  this.top = function (Repository) {
    // A new instance of 'Repository' is injected to this function everytime the handler is called.
    var repo = Repository;
  };
}

module.exports = ArticlesController;
