Global Packages

sudo npm i -g nodemon

Internal watch failed: ENOSPC

During development and using nodemon or any other such package, you may encounter an error:

Internal watch failed: ENOSPC: System limit for number of file watchers reached

To solve this issue just increase inotify watchers by:

echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p

App package version in shell

To get the NodeJS app version from package.json in the Linux shell you can use the following command:

APP_VERSION=$(npm pkg get version --workspaces=false | tr -d \")
