bolt-ts

bolt-ts is a TypeScript compiler implemented in Rust. The current implementation heavily leverages code ported from the original TypeScript compiler(tsc).

Performance

When testing a subset of type-fest functionality, bolt-ts demonstrates:

• 2.5× faster than ts-go
• 5× faster than tsc (Benchmarked on Apple M3 Max with 36GB RAM. See typescript-compiler-bench for details)

Current Status

Core functionalities are operational but require refinement. Key pending improvements include:

• Module Resolution: cache, exports/imports field support, node_modules/@types type definition resolution.
• Type Checking: various edge-case bugs.
• Output Generation: sourcemap generation, different module systems.
• And others: language service..
