3 use cases

  • Preview a static site on localhost

    Serve a static site folder on a localhost URL with one command and stop it with Ctrl+C.

    View prompt
    In the pixelcrabs repository root, run `node packages/local-runtime/bin/static-preview.mjs <absolute-path-to-site>`. Expected output: a localhost URL printed in the terminal. Verify first that the target folder contains index.html before starting the server.

  • Run the pinned OpenCode engine on a project

    Install the locked OpenCode dependencies with Bun and start its dev command against a chosen project folder.

    View prompt
    In the pixelcrabs repository, change into upstream/opencode, run `bun install --frozen-lockfile`, then run `bun dev <absolute-path-to-project>`. Expected output: the OpenCode dev process starts against that project. Verify with `bun dev --help` that the command runs before pointing it at a project.

  • Run public runtime tests before changing the runtime

    Run the dependency-free public runtime test suite to confirm a clean baseline before editing the local runtime.

    View prompt
    In the pixelcrabs repository root, run the five public runtime test files with `node --test` as listed in the README. Expected output: a pass or fail summary for each test file. Verify that no test requires installed packages before reporting a baseline.

How to use Pixelcrabs

  1. Check you have what it needs: A computer with Node.js 24 or later installed; Bun 1.3.14 installed, for the pinned OpenCode engine; A local copy of the johnzhaors-bit/pixelcrabs repository.
  2. Open johnzhaors-bit/pixelcrabs on GitHub and read the README and license.
  3. Download or clone the Pixelcrabs repository and open a terminal in its root folder.
  4. Confirm Node.js 24 or later is installed.
  5. Run node packages/local-runtime/bin/static-preview.mjs /absolute/path/to/your/site
  6. Open the localhost URL printed in the terminal.

These steps come from our top use case, Preview a static site on localhost, which also has a copy-paste agent prompt.
