[SOLVED] Github Codespaces start terminals with command on startup

Github Codespaces start terminals with command on startup

does anyone know a way to configure Github codespaces to run automatic multiple terminals with commands (eg. "npm start") on startup?

I already tried the VS-Code extension "Terminal Manager" with configured terminals.json file, but it works just in normal VS-Code. Not in Codespaces.

Thanks in advance

Solution

You can use postCreateCommand

This command is the last of three that finalizes container setup when a dev container is created.

If you have one script you can run after container created with this syntax:

{
  "postCreateCommand": "npm start"
}

// or

{
  "postCreateCommand": ["npm", "start"]
}

if you have multiply command you can separate commands with &&:

{
  "postCreateCommand": "npm install && npm start"
}
