从 stdin 读取

const prompt = "Type something: ";
process.stdout.write(prompt);
for await (const line of console) {
  console.log(`You typed: ${line}`);
  process.stdout.write(prompt);
}

bun run index.ts

for await (const chunk of Bun.stdin.stream()) {
  // chunk 是 Uint8Array
  // 将其转换为文本（假设 ASCII 编码）
  const chunkText = Buffer.from(chunk).toString();
  console.log(`Chunk: ${chunkText}`);
}

echo "hello" | bun run stdin.ts
