add-custom-domain

name: add-custom-domain description: | Add a custom domain to a Temps project and provision an automatic SSL/TLS certificate via Let's Encrypt, driven entirely from the @temps-sdk/cli CLI. Handles subdomains, apex domains, HTTP-01 and DNS-01 challenges, and wildcard domains. Use when the user wants to: (1) Add a custom domain to their Temps app, (2) Set up HTTPS/SSL for a deployment, (3) Point their own domain at a Temps project, (4) Add a wildcard domain, (5) Configure DNS for Temps. Triggers: "add custom domain", "point my domain at temps", "set up ssl", "https for my app", "wildcard domain", "add domain to project".

Add a Custom Domain

Add a custom domain to a Temps project and get automatic HTTPS. This skill drives the whole flow from the CLI; the human equivalent is Project → Domains → Add Domain in the dashboard.

When to use

The user wants their own domain (e.g. app.example.com) serving a Temps project, with an SSL certificate, instead of the auto-assigned subdomain.

Prerequisites

• The Temps CLI is authenticated. Verify, and log in to the user's instance if needed (login is a top-level command; the instance URL is the positional argument):

  bunx @temps-sdk/cli whoami || bunx @temps-sdk/cli login "<instance_url>"
  

• The user knows the domain to add and which project it belongs to.
• The user can edit DNS for the domain (or has a DNS provider connected in Temps for DNS-01 / wildcard).

Steps

1. Identify the project. If the user gave a name but not an ID, list projects and resolve it:

   bunx @temps-sdk/cli projects list --json
   

   Note the numeric id of the target project. Use it as <project-id> below.

2. Create the DNS record at the user's DNS provider so the domain points at the Temps server. Tell the user exactly what to add (you cannot create this for them unless a DNS provider is connected in Temps):

   • Subdomain (app.example.com): A record, name app, value = the server's public IP. A CNAME to the server hostname also works.
   • Apex (example.com): A record, name @, value = the server's IP. (CNAMEs are not allowed at the zone root.)
   • If the user is on Cloudflare, have them set the record to DNS only (grey cloud) during issuance so Temps' Let's Encrypt challenge isn't proxied.

3. Add the domain to the project. Default is the HTTP-01 challenge, handled automatically:

   bunx @temps-sdk/cli custom-domains create --project-id <project-id> -d app.example.com -y
   

   • Apex + Cloudflare/another provider connected, or port 80 not reachable: use DNS-01 instead (see Wildcard below) — confirm a DNS provider is connected in Settings → DNS Providers first.

4. Wildcard domains (*.example.com) require DNS-01 and a connected DNS provider. Confirm the provider is connected, then add the wildcard the same way:

   bunx @temps-sdk/cli custom-domains create --project-id <project-id> -d "*.example.com" -y
   

   Temps creates the _acme-challenge TXT record automatically via the provider.

Verify

bunx @temps-sdk/cli custom-domains list --project-id <project-id>

The domain should progress to active once DNS propagates and the certificate is issued (usually under a minute for HTTP-01). You can confirm DNS independently:

dig +short app.example.com A

If the domain stays pending: verify the DNS record resolves to the server, that port 80 is reachable (HTTP-01), and — on Cloudflare — that the proxy is off during issuance. Certificates renew automatically ~30 days before expiry.
