Contribution Guide

I'm really excited that you are interested in contributing to JSON For You. Before submitting your contribution, please make sure to take a moment and read through the following guide:

1. Search for the TODO keyword in the code first. If it's found, then you can work base on it directly.

2. Otherwise:

   • If you want to add a new feature, provide a convincing reason to add this feature. Ideally, you should open a suggestion issue first and have it approved before working on it.
   • If fixing bug, provide a description of the bug in the PR.
   • Other minor changes that don't affect the logic of the code, such as fixing typos, translating comments into English, and adding comments, are all welcome. Just submit a PR.

3. I wish to keep JSON For You lightweight and fast. Please being aware of the number of npm dependencies and their size and don't add unnecessary dependencies.

4. Run pnpm test to make sure your code pass the core tests.
