This directory contains the source code of @anthropic-ai/claude-code@2.1.88, extracted from the published npm package's source map (cli.js.map).

npm pack @anthropic-ai/claude-code@2.1.88
tar xzf anthropic-ai-claude-code-2.1.88.tgz
# Extract sources from cli.js.map into source/
node -e '
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]);
}'

The bundled cli.js is self-contained and runs directly with Node.js >= 18:

node cli.js --version          # 2.1.88 (Claude Code)
node cli.js --help             # show all options
node cli.js -p "hello world"   # non-interactive one-shot
node cli.js                    # interactive REPL

Or install globally / symlink:

npm install -g @anthropic-ai/claude-code@2.1.88
# or
ln -s "$(pwd)/cli.js" /usr/local/bin/claude

Rebuilding from the extracted source is not feasible because:

• The code uses import { feature } from 'bun:bundle' (Bun bundler compile-time API)
• The original package.json with ~hundreds of build/dev dependencies is not published
• Build configuration (tsconfig, bundler config) is not included in the source map
• 2,850 bundled node_modules dependencies are only present as source map entries

The extracted source/ tree (1,906 files, 35 MB) is useful for reading and studying the internals, not for rebuilding.

cli.js           # 13 MB self-contained Node.js bundle (the actual executable)
cli.js.map       # 57 MB source map (contains all original sources)
source/          # extracted source tree:
  src/           #   1,902 TypeScript/TSX application files
  vendor/        #   4 native module source stubs
package.json     # published package manifest (no build deps)
README.md        # this file
