Deploy Ember on Cloudflare

  1. Step 1: Set up Appflare in your Cloudflare account

    Once

    Appflare installs itself into your own Cloudflare account from your browser, and runs on the free Workers plan, as Ember does. See what Ember needs on your account.

    Set up AppflareAlready have Appflare? Install Ember

  2. Step 2: Install Ember

    Ember needs no keys or settings from you.

    Appflare generates three values for you: Setup password, Session secret and Push private key.

    It also has nine optional settings you can leave for later.

    One switch on the form puts Ember behind Cloudflare Access, so only the people who use your Appflare can open it.

  3. Step 3: Finish setting it up

    After the install, Appflare shows three short steps for Ember, on its page.

With Appflare instead of by hand

  • Nothing to build on your computerAppflare sets itself up from your browser, with no API token to create and nothing to install.
  • Updates in one clickAppflare tells you when the catalog has a new version, and Update installs it.
  • Health checksAfter every install and update, Appflare checks that the app answers.
  • It stays in your own accountEverything runs on your Cloudflare account and your plan, and Appflare records what it creates, so an uninstall removes it.

Questions

Does Ember run on Cloudflare's free plan?

Yes. Ember runs on Cloudflare's free Workers plan, and so does Appflare.

What does Ember create in my Cloudflare account?

Appflare creates a Worker for Ember and the resources it uses: D1 databases, R2 buckets and Durable Object classes. It also uses Email Routing. Appflare records each resource it creates; an uninstall deletes them, keeping any data you choose to keep.

How do I update Ember?

When the catalog has a new version, Ember's page in Appflare says Update available. Select Update: Appflare takes a snapshot first, so you can roll back to the version before. You can also let Appflare update it automatically.

Is Ember open source?

Yes, under MIT. An open-source license: you may use, change and share the app on its terms. Its source code is at github.com/NYLLON-SOFTWARE/ember-cloudflare.
