FnashJsParamBundle

Simple way to expose some symfony2 container parameters to javascript

Installation

Install

$ php composer require fnash/js-param-bundle

Register bundle

<?php
// AppKernel.php

$bundles = [
    // ...
    new Fnash\JsParamBundle\FnashJsParamBundle(),
    // ...
];

Step 3: Import routing

# app/routing.yml

fnash_js_param_routing:
    resource: "@FnashJsParamBundle/Resources/config/routing.yml"

Step 4: Configure

Given your parameters file

# app/parameters.yml

parameters:
    param1:   value1
    param2:   value2
    param3:   value3
    param4:   value4

Add some parameters you want to expose in your javascript

# app/config.yml

fnash_js_param: 
    expose: [param1, param2]

Be careful! Do not expose critical infos such as passwords etc..

Step 5: Add javascript file to base template

    {% block javascripts %}
    .............
    <script src="{{ path('fnash_js_param_js') }}"></script>
    .............
    {% endblock %}
    </body>
</html>

Get your parameters from javascript

alert(window.FnashJsParam.param1); // value1
alert(window.FnashJsParam.param2); // value2
