Working with jQuery and Silex as RestFull Resource provider

The previous post was about how to use AngularJS resources with Silex. AngularJS is great and when I need to switch back to jQuery it looks like I go back 10 years in web development, but business is business and I need to live with jQuery too. Because of that this post is about how to use the Silex RestFull resources from the previous post, now with jQuery. Let’s start:

We’re going to write a simple javascript object to handle the RestFull resource using jQuery:

var Resource = (function (jQuery) {
    function Resource(url) {
        this.url = url;
    }

    Resource.prototype.query = function (parameters) {
        return jQuery.getJSON(this.url, parameters || {});
    };

    Resource.prototype.get = function (id, parameters) {
        return jQuery.getJSON(this.url + '/' + id, parameters || {});
    };

    Resource.prototype.remove = function (id, parameters) {
        return jQuery.ajax({
            url:this.url + '/' + id,
            xhrFields:JSON.stringify(parameters || {}),
            type:'DELETE',
            dataType:'json'
        });
    };

    Resource.prototype.update = function (id, parameters) {
        return jQuery.post(this.url + '/' + id, JSON.stringify(parameters || {}), 'json');
    };

    Resource.prototype.create = function (parameters) {
        return jQuery.post(this.url, JSON.stringify(parameters || {}), 'json');
    };

    return Resource;
})(jQuery);

As you can see the library returns jQuery ajax promises, so we can use done() and error() callbacks to work with the server’s data.

Here our application example:

var host = document.location.protocol + '//' + document.location.host;
var resource = new Resource(host + '/api/message/resource');

resource.create({ id: 10, author: 'myname', message: 'hola'}).done(function (data) {
    console.log("create element", data);
});

resource.query().done(function (data) {
   console.log("query all", data);
});

resource.update(10, {message: 'hi'}).done(function (data) {
    console.log("update element 1", data);
});

resource.get(10).done(function (data) {
    console.log("get element 1", data);
});

resource.remove(10).done(function (data) {
    console.log("remove element 1", data);
});

resource.query().done(function (data) {
    console.log("query all", data);
});

And that’s all. You can get the full code of the example from my github account
