Allow user to set WebpackDevServer watchOptions.poll option for react-scripts start #1049
Description
This could potentially be done by modifying the instantiation of the WebpackDevServer in start.js to look like:
...
watchOptions: {
ignored: /node_modules/,
poll: process.env.REACT_APP_POLL || undefined,
}
...
This use case is important to me (and others) because I'm developing in a Docker container, which has issues with inotify (due to mounting volumes with aufs), which precludes the automatic rebuild without the watchOptions poll setting.

We try to avoid config flags like this as much as possible. I wonder if it would be possible to somehow detect that we're in an environment like that and fall back to polling automatically.

Same for me, I cannot count on inotify since I am using shared folders, vagrant and Virtualbox but I'd like to use polling as a workaround.

Chokidar, which Webpack uses for watching changes has an environment to force the use of polling:
CHOKIDAR_USEPOLLING. Does this fix the issue with Docker?YAmikep commentedon Nov 19, 2016
Using the env variable works for me.
There does not seem to be an env variable to set the interval though, correct?
fson commentedon Nov 19, 2016
It seems that an env variable for polling interval has been requested (paulmillr/chokidar#518) and the author has approved the idea, someone just needs to implement it 😃

Going to close as there is a path forward (described above) that is out of our control.

Thanks @fson updating script to use
CHOKIDAR_USEPOLLING=true react-scripts starthelped. Maybe would be nice to put this to react-create-app docs - or just add there reference to webpack docs... what do you guys think? As for many it might be quite an issue to solve watchmode...Enable hot reloading on Mac OS X (see react/create-react-app#1049)

Hey, I might be being docker-stupid, but where is this supposed to code? I assumed that you would replace the
commandbut that seems not to be the case?Add some development-mode configs for `client`

you know, if all these nodejs people writing cli apps used
nconf.env().argv()we'd be able to set configuration through environment variables or command line arguments.
