Apply Linting Only to Files Updated in git

[palisadoes]

We need the ability to selectively adjust our linting rules so that they are eventually applied to our entire code base.

1. Linting rules are managed by the .eslintrc.json file.
2. They are applied to the entire code base at once.
3. If we change a rule from warn to error then every file in the code base will be checked and we have frequently seen our tests fail for dozens of files in hundreds of lines of code.

This is not acceptable.

We have been trying to more strictly lint the entire code base manually, but it has been very slow.

At the user CLI

We need a way to edit .eslintrc.json with increasingly stricter linting rules in such a way that the tests are only applied to the changed files with every git commit and git push command.

These git commands must fail if the linting fails.

With Every Pull Request

We recently merged a Talawa-API pull request that checks each submitted file for linting compliance. This can be used as an example of how to run the test against individual files.

• Update PR_WORKFLOW for delta errors/warning checks #1242

You must make sure that this functionality applied for all PRs for this repository whenever the .eslintrc.json file is updated

Other

1. There may be ways to achieve the CLI goals by updating our existing Git Hooks
2. Your solution should preferably work within coding environments such as VScode

Screenshots

When complete, you should be able to convert all these .eslintrc.json file lines containing warn to error and the tests will only be applied to the changed files in git

1. You didn't update the .eslintrc.json file with all the options above. The image below is what you have implemented in the PR
2. Please open another PR to finish the job

I'm going to open another issue to finish the job so that someone else can get a chance
