automatically create a tag for package version bump

config.sh

# file: .git/config

# this pushes every branch that's already there, plus tags. It does not force push, and it does not push branch that we didn't push manually.

[remote "origin"] # or whatever it is named
    url = ...
    push = :
    push = +refs/tags/*:refs/tags/*
    

post-commit.sh

#! /bin/bash

# file: .git/hooks/post-commit
version=`git diff HEAD^..HEAD -- "$(git rev-parse --show-toplevel)"/package.json | grep '^\+.*version' | sed 's/[^0-9\.]//g'`

if [ "$version" != "" ]; then
    git tag -a "v$version" -m "`git log -1 --format=%s`"
    echo "Created a new tag, v$version"
fi

• post-commit - each time there's a version update in package.json it creates a tag with the new version number
• config - automatically pushes the tag along the commit to gh
