Deploy Wasp Apps to CapRover

Github Action to deploy Wasp Apps to CapRover

Usage

Setting up CapRover

You'll need a Caprover server setup.

Then create three apps for your Wasp app:

1. server
2. client
3. Postgres DB
   • go to one-click apps/dbs and create a vanilla PostgreSQL

Set the container ports:

• server app -> 3001
• client app -> 8043

Enable HTTPS and force redirects to HTTPS.

The env variables you will need to set:

• server app
  • DATABASE_URL (the DB you created on Caprover)
    • postgres://postgres:<pw>@srv-captain--<db-app-name>:5432/postgres
  • WASP_WEB_CLIENT_URL the client url (custom domain or the Caprover assigned subdomain)
  • JWT_SECRET
• client app
  • SERVER_APP_URL the server url

Cloudflare Notes

Set the SSL/TLS to Full (strict).

Change the A recrod to DNS only when you try to verify the domain (Clicking Enable HTTPS tries to verify the domain and it fails if the A record is proxied).

When you get a certificate for the domain, switch the A recrod back to proxied.
