ts-blank-space
A small, fast, pure JavaScript type-stripper
ts-blank-space is a fast type-stripping compiler that converts TypeScript to JavaScript. It supports a modern subset of TypeScript by erasing the types and replacing them with whitespace. That's it. It is not a type checker and does not perform any other code transformations. The underlying technique can improve build performance and simplify development. The implementation is pure TypeScript. It is simple enough to read and understand in a few minutes because it is only 700 lines of code and reuses the original TypeScript parser. The core idea is to use spaces as a substitute for type annotations. You can think of ts-blank-space as a reference implementation of this type-stripping technique. Much like other compiler techniques seen in the JavaScript ecosystem, such as tree-shaking, it is a reusable idea that any TypeScript compiler could implement. -
