Emit Decorator Metadata

If you need support for the emitDecoratorMetadata typescript compiler option, import the emitDecoratorMetadata build extension and use it in your trigger.config.ts file:

import { defineConfig } from "@trigger.dev/sdk";
import { emitDecoratorMetadata } from "@trigger.dev/build/extensions/typescript";

export default defineConfig({
  project: "<project ref>",
  // Your other config settings...
  build: {
    extensions: [emitDecoratorMetadata()],
  },
});

This is usually required if you are using certain ORMs, like TypeORM, that require this option to be enabled. It's not enabled by default because there is a performance cost to enabling it.
