Run npm start to spawn esbuild in watch mode. This serves the public/ folder, every change triggers rebuilding the bundle.js and you'll need refresh the page. The server created is in localhost:8000 by default, an initial message is printed but it probably quickly missed.
This also rebuilds the library section (data-layer) and exposes in dist/ folder.
For faster development experience, we are faking the file-system for the data-layer, if you want to use your actual file-system, you can either:
- Run the extension from VSCode on a scene
- Run
npx sdk-commands start --data-layer --port 8001in a scene & go to localhost:8000/?ws=ws://127.0.0.1:8001/data-layer
The make build in the repo root builds all the necessary for package publishment.
