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.
