fluxible-plugin-fetchr

Fetchr Plugin for Fluxible

Provides isomorphic RESTful service access to your Fluxible application using fetchr.

Usage

var Fluxible = require('fluxible');
var fetchrPlugin = require('fluxible-plugin-fetchr');
var app = new Fluxible();

app.plug(fetchrPlugin({
    xhrPath: '/api' // Path for XHR to be served from
}));

Now, when calling the createContext method on the server, make sure to send in the request object and optionally pass an xhrContext which will be used as parameters for all XHR calls:

app.createContext({
    req: req,
    xhrContext: { // Used as query params for all XHR calls
        lang: 'en-US', // make sure XHR calls receive the same lang as the initial request
        _csrf: 'a3fc2d' // CSRF token to validate on the server using your favorite library
    }
});

Dynamic XHR Paths

The fetchrPlugin method can also be passed a getXhrPath function that returns the string for the xhrPath. This allows you to dynamically set the xhrPath based on the current context. For instance, if you're hosting multiple sites and want to serve XHR via a pattern route like /:site/api, you can do the following:

app.plug(fetchrPlugin({
    getXhrPath: function (contextOptions) {
        // `contextOptions` is the object passed to `createContext` above
        return contextOptions.req.params.site + '/api';
    }
}));

Fluxible Methods Added

actionContext

• actionContext.service.read(resource, params, [config,] callback): Call the read method of a service. See fetchr docs for more information.
• actionContext.service.create(resource, params, body, [config,] callback): Call the create method of a service. See fetchr docs for more information.
• actionContext.service.update(resource, params, body, [config,] callback): Call the update method of a service. See fetchr docs for more information.
• actionContext.service.delete(resource, params, [config,] callback): Call the delete method of a service. See fetchr docs for more information.
• actionContext.getServiceMeta(): The plugin will collect metadata for service responses and provide access to it via this method. This will return an array of metadata objects.

Other Methods

The plugin also provides access to some internals and the options that were passed in.

var pluginInstance = fetchrPlugin({
    xhrPath: '/api'
});

pluginInstance.getXhrPath(); // returns '/api'
pluginInstance.getServiceClass(); // returns the fetchr instance used by the plugin

Registering Your Services

Since the fetchr plugin is in control the fetchr class, we expose this through the registerService method.

pluginInstance.registerService(yourService);

Or if you need to do this from your application without direct access to the plugin

app.getPlugin('FetchrPlugin').registerService(yourService);

Exposing Your Services

Fetchr also contains an express/connect middleware that can be used as your access point from the client.

var server = express();
server.use(pluginInstance.getXhrPath(), pluginInstance.getMiddleware());
