Top 3 Rust ECMAScript Projects

ECMAScript

  1. swc

    Rust-based platform for the Web

    Project mention: Rust Dependencies Scare Me | news.ycombinator.com | 2025-05-09

    I once wanted to contribute to the popular swc project (https://github.com/swc-project/swc). I cloned the repo, ran build, and a whooping 20GB was gone from my disk. The parser itself (https://github.com/swc-project/swc/blob/main/crates/swc_ecma...) has over a dozen dependencies, including serde.

    Meanwhile, the heaviest JavaScript parser implemented in JavaScript is more lightweight.

    I decided that I should leave this project alone and spend my time elsewhere.

  2. InfluxDB

    InfluxDB – Built for High-Performance Time Series Workloads. InfluxDB 3 OSS is now GA. Transform, enrich, and act on time series data directly in the database. Automate critical tasks and eliminate the need to move data externally. Download now.

  3. boa

    Boa is an embeddable and experimental Javascript engine written in Rust. Currently, it has support for some of the language.

    Project mention: Show HN: Nova JavaScript Engine | news.ycombinator.com | 2024-11-17

    Is this an experimental only JS engine or do you aim to implement the entire ECMAscript specification?

    I have been following the Rust Boa project, but I think that it isn't production ready, yet. https://github.com/boa-dev/boa

  4. binjs-ref

    Reference implementation for the JavaScript Binary AST format
