solijs
solijs is an npm package that allows you to dynamically link and execute functions from shared object (.so) files directly within your JavaScript projects. It provides a fast, simple, and efficient way to call C/C++ functions without the need for complex build tools like node-gyp.
Features
To install solijs, use npm or yarn:
npm install solijs
or
yarn add solijs
Usage
1. Create a .so File (e.g., libhello.so)
First, create a shared object file (.so). For example, write a simple C function that returns a value:
// hello.c
#include <stdio.h>
int give_number() {
return 3 + 2;
}
Compile it into a .so file:
gcc -shared -o libhello.so -fPIC hello.c
2. Create a JavaScript File to Call the Function
Now, use solijs to call the function inside the .so file. Here's an example:
const solijs = require('solijs');
const path = require('path');
const soPath = path.join(__dirname, 'libhello.so');
const symbol = 'give_number'; // The function name in the .so file
solijs.runValue(soPath, symbol)
.then(result => {
console.log('Result from .so:', result);
})
.catch(err => {
console.error('Error:', err);
});
API Reference
runText(soPath, symbol)
This method runs a function from the .so file that doesn't return a value but outputs text to the console.
This method executes a function from the .so file that returns an integer value.
This method retrieves the list of symbols available in the .so file.
You can check out a sample project with the usage examples and the .so files in the GitHub repository:
Why You Should Try solijs
If you're looking for a fast and easy way to integrate C/C++ code with JavaScript, solijs is a game-changer. It eliminates the need for complex build processes and gives you the flexibility to use native code directly from your JavaScript environment. Plus, it's optimized for performance, making it ideal for performance-critical applications.
