Setting up is-a.dev with Railway

Getting the CNAME Record

Navigate to the dashboard > project > service
Switch to the Settings tab and click on + Custom Domain button.
Enter the is-a.dev subdomain you want to use (ex: subdomain.is-a.dev)
Copy the Value field for @ and create subdomain.json

{
  "owner": {
    "username": "your-github-username",
    "email": "[email protected]"
  },
  "records": {
    "CNAME": "the-value-railway-gave-you"
  }
}

Copy the Value field for _railway-verify and create _railway-verify.subdomain.json

{
  "owner": {
    "username": "your-github-username",
    "email": "[email protected]"
  },
  "records": {
    "TXT": "the-value-railway-gave-you"
  }
}

After you have made the two files, you should make a pull request.

Adding the website preview is mandatory, since the CNAME value Railway gives you doesn't actually show you the website you are running.

If the PR has been merged, the DNS records will be updated in a few minutes.
If the PR has been merged but the DNS records haven't updated and you have waited 48 hours, open a GitHub issue or a help thread in the is-a.dev Discord server.
