SocketProtocolError in Debug Console
You may see the following
SocketProtocolError message in the Debug Console once you have started your SAFE application.
WebSocket connection to 'ws://localhost:8000/socketcluster/' failed: Error during WebSocket handshake: Unexpected response code: 404
Whilst these messages can be safely ignored, you can eliminate them by installing Redux Dev Tools in the launched Chrome instance as described in the debugging prerequisites section.
Node Process does not stop after stopping the VS Code debugger
VS Code does not kill the Fable process when you stop the debugger, leaving it running as a "zombie". In such a case, you will have to explicitly kill the process otherwise it will hold onto
port 8080 and prevent you starting new instances. This should be easily doable by sending Ctrl+C in the Terminal window in VS Code for
Watch Client task. Tracked here.
Chrome opens to a blank window when debugging in VS Code
- Occasionally, VS Code will open Chrome before the Client has started. In this case, you will be presented with a blank screen until the client starts.
- Depending on the order in which compilation occurs, VS Code may launch the web browser before the server has started. If this occurs, you may need to refresh the browser once the server is fully initialised.
WARNING in entrypoint size limit: The following entrypoint(s) combined asset size exceeds the recommended limit (244 KiB). This can impact web performance.
We're striving to optimise the bundle size, however with a number of different options and dependencies it's not that easy to stay below the Webpack recommended limit.
To minimize the bundle size in your project you can try restricting browser compatibility by modifying the Babel Preset targets for Browserslist and thus using less polyfills.
For more info, see this issue.
Server port change
The port that the server runs on changed from 8085 to 5000 (the ASP.NET Core default) in v4 of the SAFE Template. This was to make it compatible with deployment to Azure App Service on Linux.
