additionalFiles Extension

Copy additional files (assets, configs, etc.) to the build directory.

Setup

import { additionalFiles } from "@trigger.dev/build/extensions/core";

export default defineConfig({
  project: "<project ref>",
  legacyDevProcessCwdBehaviour: false, // recommended — CWD = build dir
  build: {
    extensions: [additionalFiles({ files: ["./assets/**", "wrangler/wrangler.toml"] })],
  },
});

Notes

• files array supports glob patterns
• Output paths match source paths relative to project root
• Works for both dev and deploy commands
• With legacyDevProcessCwdBehaviour: false, reference files using process.cwd():

const font = path.join(process.cwd(), "assets/Inter-Regular.ttf");
