The JavaScript Oxidation Compiler (oxc)

Why this project?

The goal of this project is to:

  • Create a blazingly fast JavaScript Compiler written in Rust.
  • Provide good documentation on learning Rust and compiler techniques.

And mostly importantly, an invitation for you to come and learn Rust with me. We will learn a lot from each other!

You can watch this project and also follow me on twitter if you don't have the time to Rust but would like to learn things.

Contributing

Contributions are welcome and highly appreciated. To get started, check out CONTRIBUTING.md.

Call for action

We now have a fully working parser as a baseline, it is not polished yet, so it would be much appreciated if I can invite you and review any of the code and point out for improvements. I welcome all nitpickings and bikesheddings.

I have also created some discussions for documenting my thought processes.

Milestone

The current objective is to improve the parser for real usage. Areas include:

  • API
  • Diagnostics reporting
  • Performance
  • Pass more conformance tests

You may start with https://github.com/Boshen/oxc/issues/36

Conformance

The cargo coverage command currently reports the following summary

Test262 Summary:
AST Parsed     : 43934/43934 (100.00%)

Babel Summary:
AST Parsed     : 2045/2057 (99.42%)

TypeScript Summary:
AST Parsed     : 4291/4861 (88.27%)

(The parser is failing some of the TypeScript recoverable parser tests.)
