Writing a git post-commit file in node.js

Question

I'm trying to write a git post-commit file in node.js and I'm having trouble.

The file seems to have to be named post-commit in the .git/hooks directory. Since that file can't have an extension, my vim editor won't persistently give it javascript syntax highlighting, and thus none of my snippets work, and a variety of other challenges present themselves.

What can I do? Tell git to run post-commit.js or tell vim to consider this file javascript, but that doesn't persist.

Thoughts?

You can have the post-commit file run a separate JavaScript file.

post-commit:

#!/bin/bash/
node yourJavascriptFile.js

A bit much for a single command, but useful once there's more than one build step.

That doesn't work. It can't seem to find that file. I think it executes the post-commit bash file from the top level directory, rather than from within .git/hooks

Adding the absolute path to both node and the script is best practice.

@ppovoski, absolute paths is the worst practice. It's an antipattern almost always and everywhere. Especially for user script files. In this particular case, it is better to use node $(dirname ${BASH_SOURCE[0]})/yourJavascriptFile.js to look for the script in the hooks directory. The node binary must be in the PATH.

It is also worth noting that the shebang string has a typo. There should be no trailing slash after #!/bin/bash

Use :set filetype=javascript command in vim to set file type. You may also want to enable modeline in vim and include the aforementioned command in a comment at the top of your file like this:

/* vim: set filetype=javascript : */
your_Javascript_code_goes_here()

To enable modeline in vim, add this to your ~/.vimrc file:

set modelines=2
set modeline

That will enable searching for vim modelines in the first two lines of the file.
