Getting Started

These steps will get this sample application running for you using DigitalOcean.

Note: Following these steps will result in charges for the use of DigitalOcean services

Requirements

Forking the Sample App Source Code

To use all the features of App Platform, you need to be running against your own copy of this application. To make a copy, click the Fork button above and follow the on-screen instructions. In this case, you'll be forking this repo as a starting point for your own app (see Github documentation to learn more about forking repos.

After forking the repo, you should now be viewing this README in your own github org (e.g. https://github.com/<your-org>/sample-nodejs)

Deploying the App

  1. Visit https://cloud.digitalocean.com/apps (if you're not logged in, you may see an error message. Visit https://cloud.digitalocean.com/login directly and authenticate, then try again)
  2. Click "Launch App" or "Create App"
  3. Choose GitHub and authenticate with your GitHub credentials.
  4. Under Repository, choose this repository (e.g. <your-org>/sample-nodejs)
  5. On the next two screens, leave all the defaults unchanged.
  6. Click "Launch App"
  7. You should see a "Building..." progress indicator. And you can click "Deployments"→"Details" to see more details of the build.
  8. It can currently take 5-6 minutes to build this app, so please be patient. Live build logs are coming soon to provide much more feedback during deployments.
  9. Once the build completes successfully, click the "Live App" link in the header and you should see your running application in a new tab

Making Changes to Your App

As long as you left the default Autodeploy option enabled when you first launched this app, you can now make code changes and see them automatically reflected in your live application. During these automatic deployments, your application will never pause or stop serving request because the App Platform offers zero-downtime deployments.

Here's an example code change you can make for this app:

  1. Edit style.css
  2. Add color: #ff0000; into the body section of your css.
  3. Commit the change to master. Normally it's a better practice to create a new branch for your change and then merge that branch to master after review, but for this demo you can commit to master directly.
  4. Visit https://cloud.digitalocean.com/apps and navigate to your sample-nodejs app.
  5. You should see a "Building..." progress indicator, just like above.
  6. Once the build completes successfully, click the "Live App" link in the header and you should see your updated application running. You may need to force refresh the page in your browser (e.g. using Shift+Reload).

Learn More

Deleting the App

When you no longer need this sample application running live, you can delete it by following these steps:

  1. Visit the Apps control panel at https://cloud.digitalocean.com/apps
  2. Navigate to the sample-nodejs app
  3. Choose "Settings"->"Destroy"

This will delete the app and destroy any underlying DigitalOcean resources

Note: If you don't delete your app, charges for the use of DigitalOcean services will continue to accrue.
