Forge and the Web

In addition to creating native mobile and browser apps, Forge apps can be deployed to the open web for access by mobile and desktop browsers. This means you don't need to decide between focusing on native apps or mobile websites. Both can be created from the same HTML5 code base using the Forge framework.

Forge web apps are built upon Node.js for optimum portability. The Forge build tools handle everything required to build and deploy your code.

To hear why we created this, see Introducing 'Build to Web' - simple deployment of your mobile codebase as a web app

Note: Even if you don't plan to deploy to the web, this is a great place to inspect the DOM and debug your JavaScript using the Chrome Developer Tools or the Firebug plugin for Firefox

Testing your web app

First off you'll need a Forge application. If you're not yet set up in Forge, try our Getting Started Guide then our Mobile tutorial to learn the basics.

To run the web app locally you'll need to install node.js on your machine.

Then you can test your web app using either the toolkit or command-line tools:

Toolkit

Click on the app name that you want to run from the project page. And then just click the 'Web' button in the Run section.

Toolkit run web

Once the build is complete, the app will be opened up in a new tab in your default browser. It's that simple!

Command-line

Running forge build web from your app's root directory creates the code for your web application alongside your mobile apps in just a few seconds.

Then type forge run web. This will open a new tab in your browser displaying your app.

Deploying your web app on Heroku

Your generated web app can be deployed to any node.js platform. To make deployment really easy, we've added an option to deploy the app directly to Heroku with a single command.

To set this you, you first need to set up a Heroku account if you haven't already. You can do this by following the steps in [their tutorial]http://www.heroku.com. No need to deploy an application at this stage.

Toolkit

Click on the app name that you want to run from the main Your Apps page. And then just click the 'Web' button in the Package section. If it is the first time you've done this for an application, you will be prompted to either create a new Heroku app or deploy to an existing Heroku app in your account.

Deploy app to Heroku

Once the build is complete, the app will be opened up in a new tab in your default browser.

That's it! Your app will be live on Heroku (the web address will be given in the console output). You can link this to your domain name by following instructions on the Heroku site.

Command-line

  • Return to your app directory and run forge build web to ensure your latest changes are included in the generated web app.
  • Run forge package web. If it is the first time you've done this for an application, the command line tool will ask if you want to create a new Heroku app or deploy to an existing Heroku app in your account.

Repeat steps 2 and 3 each time you want to update the deployed app.

Deploying your web app to any node.js platform

The web application lives in <your-app-folder>/release/web/heroku after you've packaged it. You can take the code from here and deploy to your favorite node.js platform like any other node.js web app.

Best practices

  • Use forge.is.web() in the Forge JavaScript framework to detect whether your app is running in a mobile browser and make any functionality or layout changes required. For example, a photo sharing app may hide native camera functionality in a web browser but show it in a mobile app.
  • If you intend your output to be viewed in a desktop browser, be mindful of how it will look at this much larger screen size and design your CSS accordingly.

  • If your Node installation is in a non-standard location (e.g. homebrew installs it to /usr/local/bin/ on OS X), you can use the node_path parameter to point us at the right place. Either use the Tools config section in the Toolkit, or edit local_config.json directly to add something like:

    "web": {
    "node_path": "/usr/local/bin/
}
