This error message indicates that the limit for file watchers has been reached. File watchers are mechanisms that monitor changes in the file system and notify programs when necessary.
A File Watcher is software or a feature that monitors changes to files and directories within a computer system’s file system.
Since npm or a process controlled by it is watching too many files, launching Quasar project in Typescript, the below error might occur.
$ yarn quasar dev
Error: ENOSPC: System limit for number of file watchers reached, watch '/home/<user-name>/<your-app>/quasar.conf.js'
Solution
Updating max_user_watches on the build node can fix it forever. For Debian put the following on the terminal:
$ echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p$ sudo sysctl --system
