Vite

To integrate cpp.js into your project using Vite as a bundler, you can utilize the vite-plugin-cppjs plugin. Start by installing these package with the following command:

npm

npm install vite-plugin-cppjs --save-dev

Yarn

yarn add vite-plugin-cppjs --dev

pnpm

pnpm add vite-plugin-cppjs --save-dev

bun

bun add vite-plugin-cppjs --dev

To enable the plugin, modify the vite.config.js file as shown below.

vite.config.js

import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
+ import viteCppjsPlugin from 'vite-plugin-cppjs'

// https://vitejs.dev/config/
export default defineConfig({
  plugins: [
+   viteCppjsPlugin(),
  ]
});

Cpp.js requires a configuration file to work. For a minimal setup, create a cppjs.config.mjs file and add the following content.

cppjs.config.mjs

import getDirName from 'cpp.js/src/utils/getDirName.js';

export default {
    paths: {
        project: getDirName(import.meta.url),
    },
};

Move your C++ code to the src/native directory. For example;

src/native/MySampleClass.h

#pragma once
#include <string>

class MySampleClass {
public:
    static std::string sample() {
        return "Hello World!";
    }
};

#endif

Modify the JavaScript file to call the C++ function. For example:

import { initCppJs } from './native/native.h'

initCppJs().then(({ MySampleClass }) => {;
  console.log(MySampleClass.sample());
});

The project is now fully set up and ready to run.

warning

Before proceeding, ensure that you have met all the prerequisites for setting up a working development environment.
