Express Resource Plus is a fork of express-resource new providing a few more routes, refactors and an extra feature or two.
**** ONLY compatible with Express 4 ****
npm: $ npm install express-resource-plus
In your main application file (i.e. app.js or server.js) just add the following:
var express = require('express'),
Resource = require('express-resource-plus'), // <- Add this (Resource really isn't needed)
app = express.createServer();
app.configure(function(){
// it is important to note that /app directory layout must follow a specific pattern to work properly see [App Layout](#app-layout)
app.set('app_dir', __dirname + '/app');
/* ... */
});
/app/:version/controllers/:controller_name/index.js routes.js
"What if I want to create a resource on the root path or change the id variable name or define middleware on specific actions?" express-resource-plus handles that by allowing you to set an options property on the controller object like so:
var before = {
auth : function(req, res, next) {
// some auth logic
next();
},
owner : function(req, res, next) {
// resource owner logic
next();
}
}
module.exports = {
options: {
root: true, // Creates resource on the root path (overrides name)
name: 'posts', // Overrides module name (folder name)
id: 'id', // Overrides the default id from singular form of `name`
before: { // Middleware support
show: before.auth,
update: [before.auth, before.owner],
destroy: [before.auth, before.owner]
}
},
index: function(request, response) {
response.send('articles index');
},
/* ... */
};
Lastly just call app.resource() with your controller name. Nesting is done by passing a function that can call app.resource() for each nested resource. Options can also be passed as the second parameter which override the options set in the controller itself.
app.resource('articles', { controller : articles }, function() {
app.resource('comments', { controller : comments });
});
You can also create non-standard RESTful routes.
./controllers/comments/index.js:
module.exports = {
index: function(request, response) {
response.send('comments index');
},
/* ... */
search: function(request, response) {
response.send("Search all comments on this article.");
},
reply: function(request, response) {
response.send("Reply to comment: " + request.params.comment);
}
};
./app.js:
/* ... */
app.resource('articles', { controller : articles }, function() {
this.resource('comments', { controller : comments }, function() {
this.collection.get('search');
this.member.get('reply');
});
});
Actions are, by default, mapped as shown below. These routs provide req.params.article for the substring where ":article" is and, in the case of the nested routes, req.params.comment for the substring where ":comment" is as shown below:
articles:
index GET /articles.:format?
new GET /articles/new.:format?
create POST /articles.:format?
show GET /articles/:articleId.:format?
edit GET /articles/:articleId/edit.:format?
update PUT /articles/:articleId.:format?
update PUT /articles.:format? ( { where : { username : 'Steve' } })
destroy DELETE /articles/:articleId.:format?
destroy DELETE /articles.:format? ( { where : { username : 'Steve' } })
query POST /articles/query.:format? ( { where : { username : 'Steve' } })
describe HEAD /articles
article_comments:
index GET /articles/:articleId/comments.:format?
new GET /articles/:articleId/comments/new.:format?
create POST /articles/:articleId/comments.:format?
show GET /articles/:articleId/comments/:commentId.:format?
edit GET /articles/:articleId/comments/:commentId/edit.:format?
update PUT /articles/:articleId/comments/:commentId.:format?
update PUT /articles/:articleId/comments.:format? ( { where : { username : 'Steve' } })
destroy DELETE /articles/:articleId/comments/:commentId.:format?
destroy DELETE /articles/:articleId/comments.:format? ( { where : { username : 'Steve' } })
query POST /articles/:articleId/comments/query.:format? ( { where : { username : 'Steve' } })
Content negotiation is currently only provided through the req.params.format property, allowing you to respond accordingly.
