We compiled our TypeScript parser to WASM

13 days ago

Encore determines application infrastructure by reading TypeScript code and provisions corresponding resources like APIs, databases, and Pub/Sub topics.
The parser, written in Rust and compiled to WASM, now runs in browsers, enabling bug reproduction via code snippets and shared links without needing local projects.
To function in browsers, filesystem dependencies were removed via Cargo features, and in-memory resolution replaces disk operations, with SDK files baked into the WASM binary.
A playground at tsparser.encore.dev allows testing and sharing parser outputs, ensuring consistency across CLI, CI, and browser environments.
