inline-cpp

Inline C++ with Node.js

Installation

npm install --save inline-cpp

or

npm install -g inline-cpp

Usage

// test.js
const compile = require('inline-cpp');

const Hello = compile `
  String func(const CallbackInfo& info) {
    return String::New(info.Env(), "Hello");
  }
`

const World = compile `
  String func(const CallbackInfo& info) {
    return String::New(info.Env(), "World!");
  }
`

console.log(Hello(), World())

Now run it:

➜ node test.js
Hello World!

The first time you run the script, it takes longer time to execute.
For each inline block of code, a native module will be generated, compiled with node-gyp and loaded dynamically.
The next time you run the script, it will reuse previous build results (unless you change the inline C++ code). The build results are cached.

For more C++ code examples, see node-addon-api

Disclaimer

This is just a prototype. I created this to check the general concept.
You're welcome to contribute! Here are some ideas:

• Use node-gyp directly, instead of invoking node node-gyp.js
• Improve error handling/reporting
• Parse/Find all finctions in the block of code, add them to exports
• Create advanced usage examples
• Cleanup unused modules from cache periodically
• ...

Debugging

You can enable some basic debug output by setting env. variable: DEBUG=inline-cpp
