Use Husky without node installed (use in Docker)

Question

We have multiple teams. Frontend and Backend. All Frontend devs have node on the computer, but not the Backend devs.

Husky (https://typicode.github.io/husky/#/) installs commit-Hooks. For the Backend devs we get the error message Can't find Husky, skipping pre-commit hook . (Because the have no nodeon their computer).

I don't want them to be forced install node, because we do all that stuff inside of a Docker-Container.

The .git/hooks look like that:

if [ -f "$scriptPath" ]; then
  # if [ -t 1 ]; then
  #   exec < /dev/tty
  # fi
  if [ -f ~/.huskyrc ]; then
    debug "source ~/.huskyrc"
    source ~/.huskyrc
  fi
  node_modules/run-node/run-node "$scriptPath" $hookName "$gitParams"

Or in later versions:

#!/bin/sh
if [ -z "$husky_skip_init" ]; then
  debug () {
    [ "$HUSKY_DEBUG" = "1" ] && echo "husky (debug) - $1"
  }

  readonly hook_name="$(basename "$0")"
  debug "starting $hook_name..."

  if [ "$HUSKY" = "0" ]; then
    debug "HUSKY env variable is set to 0, skipping hook"
    exit 0
  fi

  if [ -f ~/.huskyrc ]; then
    debug "sourcing ~/.huskyrc"
    . ~/.huskyrc
  fi

  export readonly husky_skip_init=1
  sh -e "$0" "$@"
  exitCode="$?"

  if [ $exitCode != 0 ]; then
    echo "husky - $hook_name hook exited with code $exitCode (error)"
    exit $exitCode
  fi

  exit 0
fi

Can i somehow configure husky to that the startup script executes docker-compose run app ....? I want do run the actual script inside of the container, but I don't get husky itself to execute in the container.

If I understand you right, I've solved the issue in two steps:

1. by sharing git from the host with the guest

# at docker-compose.yaml
version: '3'
services:
    app:
        build:
        ...
        volumes:
            - /usr/bin/git:/usr/bin/git
            # installing dependencies missing at guest (in my case, guest debian, host ubuntu)
            - /lib/x86_64-linux-gnu/libpcre2-8.so.0:/lib/x86_64-linux-gnu/libpcre2-8.so.0

and 2. by running the hook command inside the container, for example:

# at .husky/pre-commit

#!/bin/sh
. "$(dirname "$0")/_/husky.sh"

# instead of only npx lint-staged
docker exec great-app npx lint-staged
