Tsrs: A Port of TypeScript to Rust

You can now run your TypeScript code on Cloudflare Workers with Rust performance and safety.

Cloudflare, in collaboration with VoidZero and Max Schwenk from Owner.com, has developed and open-sourced Tsrs, a new tool that ports TypeScript code to Rust. This project aims to enable developers to run TypeScript code efficiently and securely within the Rust ecosystem, particularly for use with Cloudflare Workers. Tsrs translates a significant subset of TypeScript, including features like async/await and classes, into idiomatic Rust code. The goal is to leverage Rust's performance and memory safety benefits while retaining the developer experience of TypeScript. This release is available on GitHub, allowing the broader developer community to utilize and contribute to the project.

Tsrs represents a significant effort to bridge the gap between the ease of TypeScript development and the robust performance of Rust. By compiling TypeScript to Rust, developers can potentially achieve faster execution speeds and enhanced memory safety compared to traditional JavaScript environments. This is particularly relevant for edge computing platforms like Cloudflare Workers, where performance and security are paramount for delivering dynamic web experiences and APIs.

The project's open-source nature invites community contributions, suggesting a future where the capabilities of Tsrs could expand to cover more complex TypeScript features and integrate more deeply with the Rust ecosystem. This could lead to broader adoption for performance-sensitive applications previously constrained by JavaScript's limitations, potentially impacting how serverless and edge functions are built and deployed across the industry.
