IOS not working for me

[rayhooker]

I am having trouble getting react-native-webworker to work for me. I am trying to include it in my react native cli project. I am just trying the most basic example. I have installed as per the instructions and pod install. I created a worker.js in the root identical to your example that simply defines the self.onmessage to take a parameter data and to use self.postMessage to send it back to the application. self.onmessage = (data) => { // Message is a string // const message = e.data; self.postMessage(Message from worker: "${data}"!); }; I used the code in the example folder to launch the webworker.
` useEffect(() => { const worker = new WebWorker('./worker.js', // { // enviromnent: 'light', // } ); worker.onmessage = ({ data }) => { console.log("Got a message from worker ", data) setMessages((m) => [...m, data]); }; workerRef.current = worker; // workerRef.current.postMessage("Testing") console.log("Worker loaded", worker, worker.postMessage ) worker.postMessage("Testing") return () => { worker.terminate(); workerRef.current = undefined; }; }, []);

const postMessage = () => {
  workerRef.current.postMessage(`Message ${messages.length + 1}`);
};

....

Messages:{messages.map((message, i) => ( {message} )) ` I can see the log of the postMessage from my app. I even added code to your Javascript code that launches the thread and to the postMessage method in Javascript. I can see the messages from the app going to the thread but no response. I tried reactotron but it does nothing running in the thread. My app is running react native 0.71.6 and react 18.2.0. I have tried running it from npm run ios or launching from XCode but in neither case does to thread code appear to be responding. Any clues or hints as to possible configuration or code issues? Thanks, Ray

Does the example folder work?

I tried building/ running it: cd example npm install npx pod-install npx react-native start / npm run ios (two different terminal sessions)

I also set the output to iPhone SE 3rd generation using xcode and assigned a team to the project.

I am getting the error: /Users/rayhooker/Downloads/react-native-webworker-master/ios/RNWWWebWorker.mm:145:44 No member named 'NativeWebWorkerSpecJSI' in namespace 'facebook::react'

I did not see that error in my other project. Any clues?

Actually never mind the previous message. I made a change to my app. I had commented out {environment: 'light'} and added it back. It worked but not without the parameter environment: 'light'. Two questions:

• What is the syntax for enabling the regular environment and have you tested it?
• Also I did not plan to using the react eventing structure but did plan to use realm database that is shared by my react-native app. I will update the realm tables that are shared with my app. I can postMessages back also during my processing to hopefully have the onMessage on the client site trigger updates to the app UI to show progress. Thoughts on using environment 'light'?

The non-light environment definitely used to work. Can’t guarantee it still does 🤣 it’ll be something minor that’s broken. I’m away for a bit but can take a look when I’m back

Did you ever take a look when you got back @jacobp100

No lol. Are you also trying to use the non-light environment?
