View our documentation to get started.

Please reference the OneSignal SDK on your webpage via our CDN URL (listed in our setup documentation) instead of copying the source into another file. This is because our SDK updates frequently for new features and bug fixes.

Install the dependencies npm install then you can npm run dev. This will start a dev server on port 4001. The code will use navigator register on OneSignalSDKWorker.js to register the code as service worker.

To preview with the actual bundle you can run the build first e.g. npm run build:dev then cd into the preview folder and follow the instructions in that folder. But generally you can run docker-compose up or npm start.
