React-native Hermes app has an issue with for await

[skurgansky-sugarcrm]

React-native bundler for hermes app doesn't support for await construction. I had to replace it in this file @redux-devtools/remote/lib/cjs/devTools.js at 4 places with this code.

let consumer = this.socket.listener('error').createConsumer();
while (true) {
          const {value: data, done} = await consumer.next();
          if (done) break;
        // for await (const data of this.socket.listener('error')) {

Then i got a connection up and running.

Could you fix that please ?

Hey. I managed to connect with your suggested changes, but my state is still undefined and doesn't really look like connecting. Would you mind sharing some extra info on how you managed to solve the issue? Thanks.

☝️ Also created a PR to fix this so we won't need to patch.

[pmk1c]

Did this PR fix Hermes support for anyone? Unfortunately, it did not for me.

I see, that async iterators are now transpiled by babel, but it is still not working with Hermes. When using @redux-devtools/remote@0.9.1 with React Native on Hermes, I get the following error: "TypeError: Object is not async iterable". This stances from the transpiled async iterator implementation, which seems to have problems here.

[Methuselah96]

Yeah, looks like others are getting that error as well. PRs are welcome, I'm not sure why it's not working if it's getting transpiled.

[pmk1c]

Would a PR where the use of for await is replaced get accepted? Something like this, seems to work for me:

let consumer = this.socket.listener(channelName).createConsumer();
while (true) {
  const {value: data, done} = await consumer.next();
  if (done) break;
  // do stuff
}

Edit: This seems to be a problem with the socketcluster-client implementation: SocketCluster/socketcluster-client#150

[Methuselah96]

I would prefer to get to the root issue of why the current solution is not working, but may accept a workaround if necessary. My schedule's been pretty packed, but it should free up soon to give me time to look into this if someone doesn't beat me to it.

[Methuselah96]

babel/babel#7467 may be related.

[Methuselah96]

I wonder if TypeScript can transpile for await correctly. I've been thinking of moving to straight TypeScript transpilation and cutting out Babel entirely. Based on this test though it looks like it also uses Symbol.asyncIterator which may be the issue. 🤔

[Methuselah96]

This looks related and the TypeScript release notes mention that you need to polyfill Symbol.asyncIterator for it to work. 🤔

[Methuselah96]

#1642 may fix it. I'll release it as a patch since it seems safe enough and you can let me know whether it works or not.

[Methuselah96]

@redux-devtools@remote@0.9.2 has been published with the above fix. Let me know if it fixes the issue for you.

[pmk1c]

Unfortunately I'm still getting the same error, although now it seems as if it only happens for the this.socket.subscribe(…) and not all for await-Blocks. Since I am getting the connected to remotedev-server log.

When I add the Symbol.asyncIterator-Polyfill to the top of my App-Entrypoint, it seems to work. I guess it has something to do with require("socketcluster-client") happening before Symbol.asyncIterator = Symbol.asyncIterator || Symbol.for('Symbol.asyncIterator');, so the definition of the iterator does not work for some cases.

Nevertheless, when I add the Symbol.asyncIterator-Polyfill to the top of my App-Entrypoint, I get rid of the error, but connecting to Redux Devtools still doesn't seem to work. I can see my App sending the "START"-Message, but I cannot see any response coming from the Devtools-server. So the Remote Devtools don't start tracking anything. This should be some different error though, not related to the for await-Problem, I guess...

[pmk1c]

I tried moving the Symbol.asyncIterator-Polyfill into the index.ts of @redux-devtools/remote, but it still didn't work.

I guess for now the easiest way, is to document, that users need to put: Symbol.asyncIterator = Symbol.asyncIterator || Symbol.for('Symbol.asyncIterator'); into their App-Entrypoint for this library to work on Hermes. 🤷

[Methuselah96]

Thanks for the feedback, I'll try to take a closer look at this when my free time opens up.

[timhaak]

Hi

I just want to mention that the fix in @redux-devtools/remote@0.9.2.

causes:

Cannot assign to read only property 'asyncIterator' of function 'function Symbol() { [native code] }'

In electron.

Rolling back to 0.9.1 fixes the error.

[evgenyshenets91]

Last version doesn't work for me. But if install 0.8.0 and apply patch it works perfectly.

[YoshiYo]

Hi guys!

I've followed and tracked the issue from these tickets into endojs/endo#2220 or facebook/hermes#1389.

Do you have an idea @leotm of the configuration we need on this babel.config.json to have a proper way to have a functional Symbol.asyncInterator working?

[skurgansky-sugarcrm]

you can't configure babel when bundling for Hermes. It's hardcoded somewhere in bundler. That's why i created a ticket requesting changes in source code long ago

[pmk1c]

I was able to fix this issue by adding this index.js in my Expo project. I needed to use require instead of import to make sure bundling doesn't move the asyncIterator-fix after the require-statements.

Quite a weird work-around, but it helps in my case. This should work in a bare React Native project as well.

// index.js
Symbol.asyncIterator ??= Symbol.for("Symbol.asyncIterator");

require("expo").registerRootComponent(require("./App").default);
