'Reload' did not change when I modified a js file

[hyvenzhu]

0.28.0 does not work while 0.27.0 works well.
When I init a React-Native project, after change a js file, reload does not work well

[Chanasit]

same as me

[satya164]

Can you provide more information on what exactly not working? Live reload? HMR?

[hyvenzhu]

@satya164
'Reload JS', there is no error happened on the terminal

[shtefanntz]

I confirm this as well. I've tried previous fixes before (restarting the server, resetting the cache), but it still doesn't react to file changes.

Another thing noticed is the rather long time for the sever to start:
[6:09:42 AM] Building Dependency Graph
.
.
.
[6:15:41 AM] find dependencies (31143ms)

Besides that, the node js process hogs all the processor while starting the server. I noticed that because my computer started simulating coffee grinding :) while the packager was crawling the file system.

@hiphonezhu: Are you definitely enabling "Live Reload" in the simulator? The "Live Reload" setting is set and persisted for each app. If you build a new app it will default to not having it enabled. Can you verify that setting? You didn't mention if you were performing this step or not.

[hyvenzhu]

@dsibiski I am sure that I do not enabling "Live Reload", just 'reload js'

[jude-liu]

I have the same problem whether enable "Live Reload" or "Hot Reloading", or both of them.

I reloaded not changing. same!!

@satya164, I believe this is the same as #8635

[shtefanntz]

Still reproducing in RN 0.29 :(

[shtefanntz]

Apparently, the fix isn't related to RN.
I followed the instructions from @InnerPeace080 in #7257 and everything works as before

anyone solution? i have the same issue on 0.30 to 0.32

[guilhermebruzzi]

Same issue on 0.32 on iOS device. On Android device is working.

Reload js is not refreshing the js code and also the hot reload and live reload options are not appearing.

[togayther]

same issue on android device with react-native 0.32.

finally, i found method to solve this problem.

in file "react-native\packager\react-packager\src\node-haste\FileWatcher\index.js"
you can increase "MAX_WAIT_TIME" variable. such: 360000.

and change function "_createWatcher"

to

_createWatcher(rootConfig) {
    const watcher = new WatcherClass(rootConfig.dir, {
      glob: rootConfig.globs,
      dot: false,
    });

    return new Promise((resolve, reject) => {
      const rejectTimeout = setTimeout(
        () => reject(new Error([
            'Watcher took too long to load',
            'Try running `watchman version` from your terminal',
            'https://facebook.github.io/watchman/docs/troubleshooting.html',
          ].join('\n'))),
        MAX_WAIT_TIME
      );

      watcher.once('ready', () => {
        clearTimeout(rejectTimeout);
        resolve(watcher);
      });
    });
  }

that's all and work for me.

[afilp]

I also have exactly the same problem on v0.32: "the hot reload and live reload options are not appearing."

@togayther Does your solution solve this problem too?

[togayther]
