React Native Error: ENOSPC: System limit for number of file watchers reached

Full error message

I have setup a new blank react native app.

After installing few node modules  I got this error.

Running application on PGN518.
internal/fs/watchers.js:173
   throw error;
   ^

Error: ENOSPC: System limit for number of file watchers reached, watch '/home/badis/Desktop/react-native/albums/node_modules/.staging'

I know it's related to no enough space for watchman to watch for all file changes.

I want to know what's the best course of action to take here ?

Should I ignore node_modules folder by adding it to .watchmanconfig ?

Linux uses the inotify package to observe filesystem events, individual files or directories. Since React / Angular hot-reloads and recompiles files on save it needs to keep track of all project's files. Increasing the inotify watch limit should hide the warning messages. You could try editing # insert the new value into the system config echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p # check that the new value was applied cat /proc/sys/fs/inotify/max_user_watches # config variable name (not runnable) fs.inotify.max_user_watches=524288 Real problem However, adding more watches is putting the cart in front of the horse.
