Can we use node script instead? (argv is empty)

[mk0y]

Hi all,

I'm working on a commit-msg hook, but I'm writing it in Node.

Problem is that then process.argv is empty in such scripts.

My file begins with:

#!/usr/bin/env node

And it only contains console.log(process.argv).

Husky hook in package.json is "commit-msg": "scripts/commit-msg.js -E HUSKY_GIT_PARAMS". (file has been chmod +x)

Console.log only has array of:

[ '/usr/local/Cellar/node/11.12.0/bin/node', '/path/to/scripts/commit-msg.js', '-E', 'HUSKY_GIT_PARAMS']

So my question is how to pass git params (a commit message) to node scripts?

I'm reading commit message from

const msg = fs.readFileSync(path.join(__dirname, '../.git/COMMIT_EDITMSG'), { encoding: 'utf8' })

If anyone finds this issue, here's how I got it to work in a node script:
"commit-msg": "scripts/commit-msg.js -E HUSKY_GIT_PARAMS"

scripts/commit-msg.js:

#!/usr/bin/env node
const fs = require('fs');
const {
  HUSKY_GIT_PARAMS: gitMessagePath,
} = process.env;

const message = fs.readFileSync(gitMessagePath, { encoding: 'utf8' });
