Configure and deploy

Settings and secrets, then a native build or a Cloudflare Workers build. Read them in this order. Each page links to the pages around it.

1. Settings: config.jadpo

   A setting is a value that can differ between deployments, such as the database's address or the address emails are sent from.

2. Secrets

   A secret is a setting that must never leave the server, such as a password or an API key.

3. Database and other connection URLs

   A database or a cache takes its address from a setting.

4. Values on your machine and in production

   In production, values come from the platform's environment, or from its secret manager, which sets the same variables.

5. Checking values before the app starts

   Your app reads only the variables its settings declare.

6. A native deployable

   A deployable is one program your app is built into.

7. Declared deployables

   An app can be built into several programs, for example a Worker that serves its public API and a server that runs its back office.

8. A Workers deployable

   A deployable with target: Target.wasm runs on Cloudflare Workers.
