react-native-threads's Issues

Can't get it to work in newly generated project

I can't make it work in my projects. I tried with the latest RN, tried with older versions and always get the same error. What's interesting is that the sample project works fine.

Steps to reproduce:

react-native init TestApp

npm install

npm install react-native-threads

react-native link react-native-threads

Create new file index.thread.js in the root.

Add

import { Thread } from 'react-native-threads';

and

componentDidMount () {
    const thread = new Thread('./index.thread.js');
}

to App.js

react-native run-ios

And the result is:

Document building for release

You need to manually generate the bundle and add it to your app's assets. Example script for ios:
node node_modules/react-native/local-cli/cli.js bundle --dev false --assets-dest ./ios --entry-file index.thread.js --platform ios --bundle-output ./ios/index.worker.js
and android
node node_modules/react-native/local-cli/cli.js bundle --dev false --assets-dest ./android/app/src/main/res/ --entry-file index.thread.js --platform android --bundle-output ./android/app/src/main/ assets/index.thread.js

Hi,

constructor JSCJavaScriptExecutorFactory in class JSCJavaScriptExecutorFactory cannot be applied to given types

Hello,
Using this lib with the latest stable RN version 0.51.0 I have encoutered the following issue when trying to run an Android project

myproject/node_modules/react-native-threads/android/src/main/java/com/reactlibrary/ReactContextBuilder.java:57: error: constructor JSCJavaScriptExecutorFactory in class JSCJavaScriptExecutorFactory cannot be applied to given types;
        JavaScriptExecutor jsExecutor = new JSCJavaScriptExecutorFactory().create();
                                        ^
  required: String,String
  found: no arguments
  reason: actual and formal argument lists differ in length
1 error
:react-native-threads:compileReleaseJavaWithJavac FAILED

I have scoured the list of breaking changes since 0.49 but haven't managed to pinpoint the culprit.
I also haven't had the chance to try this on an IOS device.
Could I trouble you for a quick fix?

Thank you very much.

Do threads run application-wide or are they component-specific?

Hello,
Not an issue, mostly a question:
What I would like to know is if I start a thread in componentA like so:

const thread = new Thread('worker.thread.js');

Then in componentB run the same file:

const thread = new Thread('worker.thread.js');

Do I now have two threads running or a single one? Meaning do I have to terminate threads when unmouting my components or do all other components use the same thread, and so can I safely leave them?

Thank you.

Live reloading (re-bundling of both app and worker bundles) not working

First of all, thanks for reviving this, as indeed the other two modules do not seem to be maintained anymore!

But I've just tried to use this (on mac and ios), but haven't yet got it working. More annoying, there seems to be something stopping the packager from seeing updates I make.

Have you had any issues with the underlying watchman not picking edits?

Doesn't work with haul

Hi!

I'm trying a project with haul but I get 404s from haul dev server when it tries to fetch thread code.

Apparently in this issue @Traviskn made it work ( halp plz )

Any tips?

Thanks 🙏

Threads stop working no error message.

Platform: Android 8.0.0
Device: Samsung Galaxy S9+
React Native Version: 0.55.4

Thanks for this library. I am using realm with this. Is there anyway to know when a thread stops working? I am experimenting realm database writes through a thread. I Json.stringify(data) to send the thread message with data it should store in realm. They work at first but then the onmessage handler stops working after a while. No error messages. If there is a way to know when it stops working, I could possibly check and recreate the thread before I postMessage. Or at the very least fix whatever is causing the thread to stop working.

Android Studio Gradle Sync fails

The specified project directory '\node_modules\react-native-threads\examples\SimpleExample\android' does not exist. Need to remove stuff in build that wants stuff like /Users/tnuttall/Dev/react-native-threads/examples/SimpleExample/node_modules/react-native-threads/android/src/main/res
I am not sure who tnuttall is or why my build folder has files that need SimpleExample anyway. There are a lot of build files in \node_modules\react-native-threads\android\build\intermediates\blame\res\release\multi , \node_modules\react-native-threads\android\build\intermediates\incremental\mergeReleaseJniLibFolders, and \node_modules\react-native-threads\android\build\intermediates\incremental\packageReleaseResources that reference tnutall and SimpleExample

[Question] which RN version(s) is(are) supported yet?

Hi, this project seems to be what I need.
I'm relying on native events from a native modules coming through the bridge at a high rate. In my application right now, processing those events is slowing down the UI.
So I guess that offloading this to another JS engine instance makes sense.
Is this module working with RN 0.57.4?
Are we limited to strings exchanged in messages both ways? If so I guess I would have to stringify my objects.
Thanks in advance.

`NativeModules` is empty

I'm trying to use this module together with andpor/react-native-sqlite-storage, but something's preventing it from initializing correctly.

The error I could extract from the thread is:

TypeError: undefined is not an object (evaluating 'NativeModules["SQLite"][method]')

Seems to be related to line 84 on lib/sqlite.core.js that depends on the NativeModule bind for that module.

Is there a limitation on this kind of operation? I couldn't find any reference to NativeModules in the documentation.

I also found that NativeModules is an empty object inside a thread.

Module	Version
React Native	0.55.4
react-native-threads	0.0.12
react-native-sqlite-storage	3.3.6

IOS Release: starting Thread (Null)

HI!
Have issue, when build release version on ios ( debug and android works correctly).
I have typescript in my project and thread.js placed in dist/modules folder.
I add dist/module/thread.jsbundle to xcode project and to ios folder, but error still happend.

Android code replaces "/" with "_" in the thread path

The README asks you to re-create the filepath under the android assets folder, so replacing the "/" can cause errors in some cases where you want to keep it

Threads pause when main application goes to background or screen is locked

Hi,

I am testing this library with a simple functionality where this thread would connect to a websocket server and send a message every 6 seconds through a timer, or relay whatever string is sent through worker.postmessage call.

However, the threads stop pinging to websockets if i lock the screen or navigate away from the RN app.

This is my primary requirement - to be able to use a few of these worker threads to do some background work irrespective of RN app being on focus or not

[Android] Release mode is calling for .bundle instead of .jsbundle

Crash java.lang.RuntimeException: java.util.concurrent.ExecutionException: java.lang.RuntimeException: Unable to load script from assets 'threads/pre-load-data-worker.thread.bundle'. Make sure your bundle is packaged correctly or you're running a packager server.

my index.thread.js in the project root i.e same as index.android.js level.

what could be the reason??

Calling JS function after bridge has been destroyed

Hi,
i call a native module in my thread but the callback doesn't response
All works perfectly, also if i call other functions of this module, but with this the callback was never emitted.

net.query('SELECT LinkedEntityId, ContentDocument.LatestPublishedVersion.VersionData FROM ContentDocumentLink WHERE LinkedEntityId IN (SELECT Id FROM SM_News__c WHERE Active__c = true)', (resultQuery: any) => console.log(resultQuery));

In logcat i saw this.

W/unknown:ReactNative: Calling JS function after bridge has been destroyed: RCTDeviceEventEmitter.emit(["websocketFailed",{"message":"connect timed out","id":5}])

"react": "^16.4.1",
"react-native": "^0.55.4",
"react-native-threads": "0.0.13",

In main thread works.

What can it be?
Thanks

iOS Error

Android seems to work, but when I run iOS, I see:

2017-10-06 15:21:28.391 [fatal][tid:com.facebook.react.WebSocketExecutor] Runtime is not ready for debugging. Make sure Packager server is running.

I'm not manually running a second packager, do I need to?

Getting an error using the base example.

My react file:

import { Thread } from 'react-native-threads';

const thread = new Thread('threadfile.js');

thread.postMessage('Hello world');
thread.onmessage = (msg) => {
  console.log(msg);
}

thread.terminate();

export default class Main extends Component {...

My threadfile.js file:

import { self } from 'react-native-threads';

// listen for messages
self.onmessage = (message) => {
}

// send a message, strings only
self.postMessage('hello');

export default self;

I added the export default self; when I got an error about only being able to import js files.
I am now getting the following error:
Error downloading thread script - Response(protocol=http/1.1, code=404, message-Not Found, url=http://localhost:5714/threadfile.bundle?platform=android&dev=true&hot=false&minify=false

The path to the threadfile (./threadfile.js) is accessible from my React file for the building.

Unable to run release in android

Hello

I'm trying to run my build in release mode for Android but the app keeps crashing, my plan is to run native code that I have made in C++ which works fine when I call it in debug mode.
In release mode I get:

 --------- beginning of crash
2018-11-21 14:00:30.768 15410-15451/? E/AndroidRuntime: FATAL EXCEPTION: mqt_native_modules
    Process: com.kulascope, PID: 15410
    java.lang.RuntimeException: java.util.concurrent.ExecutionException: java.lang.RuntimeException: Unable to load script from assets 'threads/..worker.thread.bundle'. Make sure your bundle is packaged correctly or you're running a packager server.

        at com.facebook.react.devsupport.DisabledDevSupportManager.handleException(DisabledDevSupportManager.java:170)

This comes even though if I take out the native call and only do a simple post message inside the worker.thread.js which is the name of my worker.
I followed the simpleExample structure but it seems to be an issue there as well.

I have my worker.thread.bundle inside project/android/app/src/main/assets/threads/ and worker.thread.js in my project folder.
I ran the command
sudo node node_modules/react-native/local-cli/cli.js bundle --dev false --assets-dest ./android/app/src/main/res/ --entry-file worker.thread.js --platform android --bundle-output ./android/app/src/main/assets/threads/worker.thread.bundle

I'm running
react-native: 0.55.2
react-native-threads: 0.0.13 I use this version in relation to this bug

What am I doing wrong ?

Gist

I think this is the last error I should solve before successfully upgrading to react-native 0.57.
Has anybody had this error? Please help me.

Thank you.

[Question] Using a thread worker written in TypeScript

I'm using Typescript and a worker thread using a lot of modules.
I guess I should take the release route even for development to produce a correct javascript file to be used by this library. Am I wrong?

Native module is not installed correctly

Hello,

I'm trying to use react-native-device-info lib with react-native-threads on Android. In iOS works perfectly.

So I put on the MainApplication.java the dependency for RNThreadPackage

new RNThreadPackage(
              mReactNativeHost,
              new RNDeviceInfo() <-- here
)

But throws this error:

When i try to use react-native-device-info on main regular thread of the react-native, works perfectly, so i think that the installation of this native module it's ok and has any issue or conflict with react-native-threads.

Somebody has any workaround or tip to help-me to investigate this issue?

Component fails to render after starting/initialising thread in iOS

Hi, In my app i have a side-menu as well which works perfectly fine for the android app, but in iOS the side-menu fails to render anything as soon as I start the thread by calling
this.thread = new Thread('Thread.js')
Now i cannot even debug from React-native-debugger/remote debugging as using it will cause thread itself to throw error package manager is not running which is already an open issue.
Is there something I am missing to initialise the app properly for iOS app.

Exception downloading Thread script to file.

Its not a RN 0.56 problem, rather actually putting the threads file in any Directory other than app root causes this.

const thread = new Thread('./services/contacts.js');
thread.onmessage = (message) => console.log(message);

iOS Bundle Release

I am experiencing an issue with threads in production/release.

2018-01-31 16:27:03.209993+0000 TestApp[72678:38924584] starting Thread (null)

Make sure you're running a packager server or have included a .jsbundle file in your application bundle.

My Threads don't live in the root of the project, they live in ./App/Workers/*.thread.js. I have also followed the documentation for building .jsbundle files and adding them to ./ios.

In development, everything works as expected:

2018-01-31 17:14:34.192937+0000 TestApp[75866:39010763] starting Thread http://localhost:8081/./App/Workers/Test.Generate.thread.bundle?platform=ios&dev=true&minify=false

Am I experiencing this issue because my thread files don't live in the root of the project?

latest RN Android NativeModuleRegistryBuilder Changed

facebook/react-native@407e033#diff-3b4df9d6f8274463f67e764159059571

react-native-threads/android/src/main/java/com/reactlibrary/ReactContextBuilder.java

Line 72 in 870257f

    
           NativeModuleRegistryBuilder nativeRegistryBuilder = new NativeModuleRegistryBuilder(reactContext, this.instanceManager, false);

Main thread is not receiving the message from thread.postMessage

I can see the the method below from ThreadSElfModule.java being called but the message does not reach the onmessage of main application:
@ReactMethod
public void postMessage(String data) {
if (parentContext == null) { return; }

    parentContext.getJSModule(DeviceEventManagerModule.RCTDeviceEventEmitter.class)
            .emit("Thread" + String.valueOf(threadId), data);
}

Not sure where to go from here!!

Building for Release

@Traviskn Having created the bundle of the worker using your Building for Release instructions, with the default name index.thread.js, I still see it being pulled down from the dev server and not using the offline bundle, whereas index.js is not showing up and it is using the offline bundle main.jsbundle.

Does anything need to modified in AppDelegate.m to make mention of the thread webworker - index.thread.jsbundle?

// jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index" fallbackResource:nil];
jsCodeLocation = [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];

  RCTRootView *rootView = [[RCTRootView alloc] initWithBundleURL:jsCodeLocation
                                                      moduleName:@"..."
                                               initialProperties:nil
                                                   launchOptions:launchOptions];

I see that is what causes the offline bundle to be used for the main index.js, but how does it know to use the offline bundle for the webworker index.thread.js?

"No Bundle URL Present" when making a new Thread class

I tried a few solutions from google but nothing helps. The moment I add const thread = new Thread('./thread.js') I get this error.

Since I'm running an ejected Expo error I tried getting the example running but that failed for completely different reason.

My dependencies:

    "expo": "^30.0.0",
    "expo-graphics": "1.0.0-alpha.1",
    "expo-three": "3.0.0-alpha.1",
    "expokit": "^1.7.1",
    "react": "16.3.1",
    "react-native": "https://github.com/expo/react-native/archive/sdk-30.0.0.tar.gz",
    "react-native-elements": "0.18.5",
    "react-native-threads": "0.0.16",

Update: I made the examples work. I'll see if I can get it running using that.

Cannot find module "NativeModules"

Hi, I am having some trouble getting this plugin up and running with my project. I have basically copied the worker.thread.js and then instantiate the worker much like in the example in the readme:

import { Thread } from 'react-native-threads'

console.log('hello')
export const hintWorker = () => {
  // start a new react native JS process
  const thread = new Thread('worker.thread.js')

  // send a message, strings only
  thread.postMessage('hello')

  // listen for messages
  thread.onmessage = (message: any) => console.log(message)

  // stop the JS process
  thread.terminate()
}

However, when I run hintWorker(), I get an error-message, that it cannot find the NativeModules, which, as far as I know, is from React-Native. I guess it cannot find it inside the worker.thread.js-file.

    "react-native": "^0.51.0",
    "react-native-threads": "^0.0.10",

Downloading files using threads in Background

Hi,

I am creating a react native app, and I want to download some pdf files (Around 10, 2MB each) in the background. Do you think "react-native-threads" is a good solution for my use case?

I know this is not an Issue, but I did not know where to ask. I am sorry about that.

Execution failed for task ':react-native-threads:compileReleaseJavaWithJavac'.

I tried to do react-native link but thing is I am also using react-native-navigation which has bit different implementation of MainApplication.java file and thus its unable to get the context of ReactApplication.

Below is the implementation of my MainApplication.java file
`
public class MainApplication extends NavigationApplication {

@Override
public boolean isDebug() {
    // Make sure you are using BuildConfig from your own application
    return BuildConfig.DEBUG;
}

protected List<ReactPackage> getPackages() {
    // Add additional packages you require here
    // No need to add RnnPackage and MainReactPackage
    return Arrays.<ReactPackage>asList(
        new RNThreadPackage()
    );
}

@Override
public List<ReactPackage> createAdditionalReactPackages() {
    return getPackages();
}

@Override
public String getJSMainModuleName() {
    return "index";
}

}
`

Exception calling object as function: Module RCTDeviceEventEmitter is not a registered callable module

Hi, thank you for making this module. I've encountered an issue after compiling and launching my app. Here are some additional details.

"react": "^16.4.1",
"react-native": "^0.56.0",
"react-native-threads": "0.0.13"

worker.thread.js is in my root folder
I bundle it with the provided commands to assets/threads

The file is found and I am able to get a console log out of it. I have removed all code from the worker file, this is it:

import { self } from 'react-native-threads';
console.log('hello from worker');
console.log(self)

However, after the two console log lines, the app crashes and produces this error:

07-20 14:47:15.090 29399-29494/? I/ReactNativeJS: hello from worker
07-20 14:47:15.098 29399-29494/? I/ReactNativeJS: { onmessage: null, postMessage: [Function] }

I am not using postMessage or onmessage at all in the rest of my code, only registering the worker.

Everything works fine in dev mode, only release gets messed up after launching the app.

Would it be possible to point me in the right direction?

Import dependencies in thread

Hello again,
Is it possible to require a module in the thread? Something like:

import _ from 'lodash'
self.onmessage = message => {
//
}

Thank you.

Module undefined

With the latest version of react native, the module import of Thread returns undefined. Any advise?

Release APK unable to pickup thread js file and hence crashes

Hello again,
I trying to check the release version of my app after using Thread module in one of the pages and I have followed the steps to compile my thread.js and support.js file as per the command give accordingly and it generates the file as well, now when I open the page which is associated with this Thread module my app closes and tried removing it form the page and it works fine.

So probably I there might be some issue while building the bundle file.
PS: I have 2 thread worker files and I have compiled both the files.

Is there anything else I have to do for multiple files ?

And just FYI: in your simpleexample folder in package.json the command for build-thread-android has spacing in folder names hence does not work.

This is the line

Is there a simple way to solve that?

[Question] editing android native code for linking the package

Hello.

My react native app is integrated with a pre-existing android native application.
So, I've followed the steps explained in this link.

http://facebook.github.io/react-native/docs/integration-with-existing-apps

The problem is that
When I try to link react-native-threads package upon this basis, I don't have a certain argument to feed.
The bridging activity starts like this.

public class MyReactActivity extends Activity implements DefaultHardwareBackBtnHandler {
    private ReactRootView mReactRootView;
    private ReactInstanceManager mReactInstanceManager;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        mReactRootView = new ReactRootView(this);
        mReactInstanceManager = ReactInstanceManager.builder()
                .setApplication(getApplication())
                .setBundleAssetName("index.android.bundle")
                .setJSMainModulePath("index")
                .addPackage(new MainReactPackage())
                .setUseDeveloperSupport(BuildConfig.DEBUG)
                .setInitialLifecycleState(LifecycleState.RESUMED)
                .build();
        // The string here (e.g. "MyReactNativeApp") has to match
        // the string in AppRegistry.registerComponent() in index.js
        mReactRootView.startReactApplication(mReactInstanceManager, "MyReactNativeApp", null);

        setContentView(mReactRootView);
    }

    @Override
    public void invokeDefaultOnBackPressed() {
        super.onBackPressed();
    }
}

As explained in the Readme file of this package,

Also note that only the official react native modules are available from your threads (vibration, fetch, etc...). To include additional native modules in your threads, pass them into the RNThreadPackage constructor after the mReactNativeHost like this: new RNThreadPackage(mReactNativeHost, new ExampleNativePackage(), new SQLitePackage())

I tried to feed "mReactNativeHost".

At first, I tried this code

private ReactRootView mReactRootView;
...
mReactNativeHost = ((ReactApplication) getApplication()).getReactNativeHost();
...
new RNThreadPackage(mReactNativeHost, new BlePackage())

However, this gives me the log like this:

android.app.Application cannot be cast to com.facebook.react.ReactApplication

I know this is more about the general knowledge on android.

But I'm trying to run bluetooth communication on another process using this package.

So, please help me if any of you guys had an experience like this.

Thank you.

Doesn't work with realm

Hi!
I'm trying a project with realm but I catch error "com.facebook.react.JavaScript (15): EXC_BAD_ACCESS (code=1, address=0x0)" after (Cmd + R), testing also did on android (real devices), it works without errors, but it does not start another thread.

Thanks!

UIManager is undefined. The native module config is probably incorrect.

If I import native modules in worker.thread.js (from SimpleExample)

import { self } from 'react-native-threads';
import { UIManager } from 'react-native';    // <------ this line
import './config';

let count = 0;

console.tron.log(`MANAGER ${UIManager}`); // <------ and another one

self.onmessage = message => {
  console.tron.log(`THREAD: got message ${message}`);

  count++;

  self.postMessage(`Message #${count} from worker thread!`);
}

thread fails with UIManager is undefined. The native module config is probably incorrect..
I was under impression that UIManagerStubModule (and other modules declarations here) should have fixed this, but error still appears.

undefined is not an object (evaluating ThreadManager.startThread)

i'm trying to install lib with Mostly automatic installation just running react-native link react-native-threads. I've cleaned up my app and rebuild, and:

So i can confirm that the lib has attached on Libraries folder:

But libRNThread.a is missing on Link Binary With Libraries.

So.. the command react-native link react-native-threads is missing to attach libRNThread.a on Link Binary With Libraries?

Threads getting killed on back-button press

Hi, Im using this thread lib on the react facebook example app.
When I press the back button from the main screen of my app the app goes to background (terminates kind-of). Thats the default behavior as far as i know.

The problem is, when this happens, the onHostDestroy method gets called. So the threads are terminated.
When I re-enter the app, nothing gets created, as the app is in a intermediate state, so the threads arent re-created. Instead a onHostResume gets called.

For now i have fixed this by changing the onHostDestroy method just to call onHostPause. But i dont know if this is a good long term solution.

Running on a device

I am having issues getting Threads running on a device either in Development or in Release mode.

I have three files within App/Workers/*.thread.js. I am alerting within the Thread also for debugging purposes and it never appears when I run any three of these threads on a device.

Any ideas to where I am going wrong?

iOS bundle won't load

I have everything working as long as the package manager is running. But as soon as I try to build for production, or indeed even just bundle the thread with --dev true, it fails to load the bundled thread code.

Looking through the logs, I noticed this:
starting Thread file:///var/containers/Bundle/Application/0C3714D5-035B-480F-A9A7-4D2455ECF6BA/MyApp.app/main.jsbundle

My thread entry point is navigator.js (and output as well)... Which would imply that the fallback incorrectly falls back to the name "main" causing it to load the wrong JS bundle?
