Auto detect runtime and set correct build steps in deploy.yml

[they-cloned-me]

What problem are you trying to solve?

I recently created a sample project that uses Bun for runtime. The deploy.yml assumed NodeJS to be the runtime, and added this step:

- name: Install Node.js
        uses: actions/setup-node@v4
        with:
          node-version: lts/*

meanwhile I expected it to be

 - name: Install Bun
        uses: oven-sh/setup-bun@v1

Describe the solution you'd like

It would be cool to auto detect the project’s runtime and set the correct build steps—just like the framework is auto detected (cool feature 👌) e.g,

• for Node base projects, check for the presence of package.json and use the Node build step
• For Bun, check for bun.lockb and use the Bun preset
• etc...

Alternatively, on the Deno dashboard, the deploy.yml that Deno will add to the repo could be shown to the user before they create the project, giving them the ability to make these quick adjustments.

Thanks 🦕
