jsii

What is jsii?

The jsii npm package is a tool that allows developers to write code in TypeScript and then use it in other programming languages such as Python, Java, and C#. It facilitates the creation of multi-language libraries by generating bindings for different languages from a single TypeScript codebase.

What are jsii's main functionalities?

TypeScript to Python

This feature allows you to write a class in TypeScript and then use it in Python by generating the necessary bindings.

const jsii = require('jsii');

// Define a TypeScript class
class HelloWorld {
  sayHello() {
    return 'Hello, world!';
  }
}

// Export the class using jsii
module.exports = { HelloWorld };

// In Python, you can now use the generated bindings
# from your_module import HelloWorld
# hello = HelloWorld()
# print(hello.sayHello())

TypeScript to Java

This feature allows you to write a class in TypeScript and then use it in Java by generating the necessary bindings.

const jsii = require('jsii');

// Define a TypeScript class
class Calculator {
  add(a, b) {
    return a + b;
  }
}

// Export the class using jsii
module.exports = { Calculator };

// In Java, you can now use the generated bindings
// Calculator calculator = new Calculator();
// int result = calculator.add(1, 2);
// System.out.println(result);

TypeScript to C#

This feature allows you to write a class in TypeScript and then use it in C# by generating the necessary bindings.

const jsii = require('jsii');

// Define a TypeScript class
class Greeter {
  greet(name) {
    return `Hello, ${name}!`;
  }
}

// Export the class using jsii
module.exports = { Greeter };

// In C#, you can now use the generated bindings
// Greeter greeter = new Greeter();
// string greeting = greeter.greet("World");
// Console.WriteLine(greeting);

Other packages similar to jsii

swig

SWIG (Simplified Wrapper and Interface Generator) is a tool that connects programs written in C and C++ with various high-level programming languages. Unlike jsii, which focuses on TypeScript, SWIG is used for C/C++ and supports a wide range of languages including Python, Java, and C#.
