This repo demonstrates how to compile a TypeScript source file into C++ and then build a native Node.js module from it.
Only works on Linux and macOS, Windows is currently not supported.
Clone the repo:
git clone https://github.com/compilets/quick-start.gitInstall deps and start building:
cd quick-start
npm installRun the benchmark script:
./benchmark.jsTo convert a TypeScript project, run compilets gen, which creates a C++
project under the cpp-project/ directory.
$ npx compilets gen
Done. Made 50 targets from 79 files in 521ms
$ ls cpp-project/
BUILD.gn eratosthenes.cpp out/
cpp/ eratosthenes.hThe eratosthenes.h and eratosthenes.cpp files are converted from the
eratosthenes.ts file, which include both the translated C++ implementation of
the TypeScript code, and extra bindings code for Node.js native module.
The BUILD.gn and a hidden file .gn are the configuration files of GN build
system, the out/ directory stores build files, and cpp/ directory contains
dependencies used by the generated project.
To build the C++ project, run compilets build, and a eratosthenes.node file
will be generated under cpp-project/out/Release, which is the built native
module.
$ npx compilets build
ninja: Entering directory `out/Release'
ninja: no work to do.
$ node -e "console.log(require('./cpp-project/out/Release/quick-start.node'))"
