Sends native desktop notifications if CLI apps fail

Technically: if a command exits with an exit code other than 0

To use it in your project:

$ npm install --save-dev cli-error-notifier 

To use it globally:

$ npm install --global cli-error-notifier 

It requires Node.js (v4 or greater).

$ onerror --help Sends native desktop notifications if CLI apps fail	Usage $ onerror <command> [options]	Options --title, -t Sets the title of the notification. Default: "An error has occured" --message, -m Sets the message body of the notification. Default: "Check the terminal for more information" --icon, -i Sets an icon. Can be any absolute path. --sound, -s Defines which sound to use. Use "mute" to disable default sound notification. Options: Mute, Basso, Blow, Bottle, Frog, Funk, Glass, Hero, Morse, Ping, Pop, Purr, Sosumi, Submarine, Tink Default: Bottle --version -v Displays the version number. --help -h Displays the help.	Examples $ onerror "wget unknown-host.xyz" $ onerror "wget unknown-host.xyz" -s mute $ onerror "wget unknown-host.xyz" -t Error -m "My error message" $ onerror "wget unknown-host.xyz" -s Glass -i https://cdn.rawgit.com/npm/logos/31945b5c/npm%20square/n-64.png 

This little CLI comes in handy when writing build scripts.

Let’s imagine you have setup the following npm script for linting your JavaScript files:

{ "scripts": { "eslint": "eslint src", } }

With using cli-error-notifier a desktop notification can be generated at the moment the linting fails:

{ "scripts": { "eslint": "onerror \"eslint src\"", } }

This is especially useful for watching files while developing. You could use it in conjunction with onchange like in the following example:

{ "scripts": { "eslint": "eslint src", "eslint:fix": "npm run eslint --silent -- --fix", "eslint:watch": "onchange \"src/**/*.js\" -- onerror \"npm run eslint --silent\"" } }

It also works flawlessly together with npm-run-all.

cli-error-notifier uses the brilliant node-notifier and therefore should work with Notification Center for macOS, notify-osd/libnotify-bin for Linux, Toasters for Windows 8/10, or taskbar Balloons for earlier Windows versions. Growl is used if none of these requirements are met.

• onchange - Watch files and folders and run a command when anything is changed.
• npm-run-all - CLI tool to run multiple npm-scripts in parallel or serial.
