Can this be used to sync JSON files by creating commits?

[zefir-git]

I am new to GitHub actions. I am looking to create a workflow that would allow me the following:

1. The workflow is triggered by a commit on a file e.g. /folder/a.json (all properties are strings and all index:property pairs are on a new line)
2. If a line:
   a. is added: workflow inserts the same line in all other .json files in /folder
   b. is removed: workflow removes that line in all order .json files in /folder

I would really appreciate your help on this.

This should be possible. But git-auto-commit will only play a small role in that workflow.
git-auto-commit will only detect changes in files, commit them and push them pack to GitHub.

The logic that detects if a line has been added or removed and then updates a JSON file is up to you.

Here is a very basic example of how such a workflow could look like:

name: Demo

on:
  push:
    paths:
      - 'folder/**.json'

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout Repo
        uses: actions/checkout@v2

      - name: Update JSON Files
        run: ./path/to/binary/to/run/your/logic

      - uses: stefanzweifel/git-auto-commit-action@v4
        with:
          commit_message: Changed JSON Files

Thanks a lot! Do you know if there any workflows that can detect added/removed lines? I haven't used GitHub workflows or Docker before and I couldn't really understand how it works from the docs.
Is it possible to run a node.js app that would make the changes to the rest of the commits?

The problem you're trying to solve sounds very specific. Highly unlikely that a Action for this exists.

Is it possible to run a node.js app that would make the changes to the rest of the commits?

Yes. In my example you could replace ./path/to/binary/to/run/your/logic with node index.js or node path/to/your/app.

A step using run has direct access to the CLI. If you want to a bit more complex stuff you can also write multiple lines like this:

      - name: Update JSON Files
        run: |
            echo "Hello World";
            npm install;
            node detect-changes.js;
            echo "Done";

Thanks a lot. Just a couple of final questions, where would I create the JS file so that it's accessible to the workflow and how could I access the files in the repository? Would I need to clone the repo, commit and then push?

I figure it out, thanks for your help.
