### Extracting Source Code with Node.js

Source: https://github.com/exhen/claude-code-2.1.88/blob/main/README.md

This script uses Node.js to parse a source map file (cli.js.map) and extract the original source code into a specified directory. It handles nested directories and skips content from node_modules.

```javascript
const fs = require("fs"), path = require("path");
const map = JSON.parse(fs.readFileSync("cli.js.map", "utf8"));
for (let i = 0; i < map.sources.length; i++) {
  if (map.sourcesContent[i] == null || map.sources[i].includes("node_modules")) continue;
  const rel = map.sources[i].replace(/^\.\.\//g, "");
  const out = path.join("source", rel);
  fs.mkdirSync(path.dirname(out), { recursive: true });
  fs.writeFileSync(out, map.sourcesContent[i]);
}
```
