Hi @Daniel Pinfold , we are sorry to hear you're facing this issue.
Here are the detailed steps to configure a static web app deployed React app to serve JavaScript content properly
- Ensure your React app is being built correctly and artifacts are generated in the /build folder that gets deployed. Test locally.
- Add a mime-types.json file to the client folder to specify JavaScript mime-type
- Validate the build artifacts contain your JS bundles with the .js extension and not something like .txt.
- Check the App Service logs in Kudu for any errors processing the JavaScript files during deployment.
- Enable diagnostics logging and trace failed requests to see how JavaScript files are handled.
If the issue persists after trying these steps, please let us know.
