example-typescript-packaging

A minimal TypeScript example that packages a Python app, deploys it to Tower, runs it, and streams the output back to your terminal. Uses tower-package-wasm for packaging and a generated OpenAPI client (openapi-fetch + openapi-typescript) for the API calls.

Generating the client

The Tower OpenAPI spec is checked in at openapi.yaml. After npm install:

npm run generate

This writes src/generated/api.ts. Re-run whenever openapi.yaml changes. To refresh the spec itself, pull it from the live service:

curl -sL https://api.tower.dev/v1/openapi.yaml -o openapi.yaml

Running the example

Copy .env.example to .env and set TOWER_API_KEY (optionally override TOWER_APP_NAME). Then:

npm install
npm run deploy-and-run

Expected output:

Created app "test-typescript-deploys".
Built package: 360 bytes, 1 app file(s).
Deployed app "test-typescript-deploys" version v1.
Started run #1.
  hello from test-typescript-deploys
Run #1 complete.

src/index.ts reads as six numbered steps: load config, ensure the app exists, read the files, build the bundle with tower-package-wasm, and upload them to the deploy endpoint, then run the app and stream its output.

deploy-and-run invokes node --experimental-wasm-modules because the published tower-package-wasm is the bundler build and imports .wasm as an ES module.
