# Usage

> Learn how to use JS-Confuser's API

JS-Confuser exposes a simple API that allows you to obfuscate your code with just a few lines of code. The provided code example will obfuscate the file `input.js` and write the output to a file named `output.js`.

```js title="Example Usage" theme={null}
import JSConfuser from "js-confuser";
import { readFileSync, writeFileSync } from "fs";

// Read input code
const sourceCode = readFileSync("input.js", "utf8");
const options = {
  target: "node",
  preset: "medium",
};

JSConfuser.obfuscate(sourceCode, options)
  .then((result) => {
    // Write output code
    writeFileSync("output.js", result.code);
  })
  .catch((err) => {
    // Error occurred
    console.error(err);
  });
```
