In Bun, the console object is an AsyncIterable that yields lines from stdin.
index.ts
const prompt = "Type something: ";
process.stdout.write(prompt);
for await (const line of console) {
  console.log(`You typed: ${line}`);
  process.stdout.write(prompt);
}
Running this file starts a never-ending interactive prompt that echoes whatever you type.
terminal
bun run index.ts

Type something: hello
You typed: hello
Type something: hello again
You typed: hello again
Bun also exposes stdin as a BunFile, Bun.stdin. Use it to incrementally read large inputs piped into the bun process. Chunks aren’t guaranteed to be split line-by-line.
stdin.ts
for await (const chunk of Bun.stdin.stream()) {
  // chunk is Uint8Array
  // this converts it to text (assumes ASCII encoding)
  const chunkText = Buffer.from(chunk).toString();
  console.log(`Chunk: ${chunkText}`);
}
Running stdin.ts prints whatever is piped into it.
terminal
echo "hello" | bun run stdin.ts

Chunk: hello
