Converting stream to string

You can convert a stream to a string by using Buffer.from and a for await:

async function streamToString(stream) {
  const chunks = []
  for await (const chunk of stream) {
    chunks.push(Buffer.from(chunk))
  }
  return Buffer.concat(chunks).toString('utf-8')
}

Converting stream to Array

You can convert a stream to an array using Array.fromAsync:

await Array.fromAsync(stream)

// or before Node 22

async function streamToArray(stream) {
  const chunks = []
  for await (const chunk of stream) {
    chunks.push(chunk)
  }
  return chunks
}

Converting stream to Buffer

You can convert a stream to a Buffer using Array.fromAsync with a mapper:

async function streamToBuffer(stream) {
  const chunks = await Array.fromAsync(stream, (chunk) => Buffer.from(chunk))
  return Buffer.concat(chunks)
}

// or before Node 22

async function streamToBuffer(stream) {
  const chunks = []
  for await (const chunk of stream) {
    chunks.push(Buffer.from(chunk))
  }
  return Buffer.concat(chunks)
}
