hubmon

Run a command and restart it when file changes.

Install

You can install this command line tool with npm like this:

npm install -g hubmon

Usage

Basic usage

If you want to run a command and rerun it each time a file changes, prefix your command with hubmon.

Here’s an example if you want to execute ls -la src:

hubmon ls -la src

Using the --watch option

By default, all files (except dotfiles) are watched (with the **/* glob pattern). If you want to only watch some files, you can use a different glob pattern with the --watch option (or its short -w alias) like this:

hubmon --watch '*.txt' ls -la src

WARNING: the quote around the glob pattern is important.

Defining aliases for script runners

If you often use hubmon with commands like node, python or ruby, it can be nice to set some aliases like these:

alias wnode='hubmon node'
alias wpython='hubmon python'
alias wruby='hubmon ruby'

This way, in a few keystrokes, you can add the letter w (like watch) at the beginning of your command to trigger hubmon’s watching mechanism:

wnode my-script.js

A note about Volta

If you’re using Node.js with volta, we have a special trick for you. By default, the way volta handles automatic version switch would break. We added some special code so the versions you defined for npm, yarn and node are the right one.
