SWC-based TypeScript/JavaScript transform for OpenWorkers.
- Strips TypeScript types
- Transforms
export default { ... }→globalThis.default = { ... }(required for V8 classic script evaluation) - Collects named exports in
globalThis.__exports, where the runtime finds a Durable Object class
use openworkers_transform::{parse_worker_code, CodeLanguage}; let code = b"export default { fetch() { return new Response('hello'); } }"; let result = parse_worker_code(code, CodeLanguage::JavaScript).unwrap(); // => "globalThis.default = { fetch () { return new Response('hello'); } };"
| Pattern | Result |
|---|---|
export default { ... } |
globalThis.default = { ... } |
export default function f() {} |
globalThis.default = function f() {} |
export default class C {} |
globalThis.default = class C {} |
export { x as default } |
globalThis.default = x |
Re-exports (from '...') |
Kept as-is |
Named exports (export class X, export { a as b }) |
Declarations kept, and globalThis.__exports = { "X": X, "b": a } at the end |
