A TypeScript to C++ transpiler

tscpp

tscpp is an alternative TypeScript compiler.

It currently transpiles to C++.

Build instructions

This project is only tested to compile with the clang version 16 on macOS. You will need to install it along with meson and ninja. For faster rebuilds you may install ccache as well.

Setup:

meson setup build

Build:

ninja -C build

After building, the tscpp executable will be found in ./build/src.

Usage:

./meta/compile tests/hello-world.ts
./a.out

Goals

1. Compatibility with TypeScript
2. Executable performance
3. Compile performance
4. Fun!

Compatibility

tscpp wants to be able to compile more or less any TypeScript file into binary. This is a high goal post, but it should theoretically be possible, so why not aim for the stars?

Executable performance

JavaScript programs are generally quite slow in comparison to those written in systems programming languages like C, C++, Rust etc. However, TypeScript has type annotations, it just doesn't optimize the code around them. What if we were to optimize generated code around those type annotations, would the language still be slow?

Compile performance

Many modern web projects take ages to compile, for some projects it may take even more time to compile than for modern C++ projects. tscpp aims to be the fastest TypeScript compiler.
