The methods returns a promise that resolves when the end
event fires on the stream, indicating that there is no more data to be read. The stream is switched to flowing mode.
Get the stream
as a string.
Type: object
Type: string
\
Default: 'utf8'
Encoding of the incoming stream.
Type: number
\
Default: Infinity
Maximum length of the returned string. If it exceeds this value before the stream ends, the promise will be rejected with a getStream.MaxBufferError
error.
Get the stream
as a buffer.
It honors the maxBuffer
option as above, but it refers to byte length rather than string length.
Get the stream
as an array of values.
It honors both the maxBuffer
and encoding
options. The behavior changes slightly based on the encoding chosen:
When encoding
is unset, it assumes an object mode stream and collects values emitted from stream
unmodified. In this case maxBuffer
refers to the number of items in the array (not the sum of their sizes).
When encoding
is set to buffer
, it collects an array of buffers. maxBuffer
refers to the summed byte lengths of every buffer in the array.
When encoding
is set to anything else, it collects an array of strings. maxBuffer
refers to the summed character lengths of every string in the array.
If the input stream emits an error
event, the promise will be rejected with the error. The buffered data will be attached to the bufferedData
property of the error.
(async () => {
try {
await getStream(streamThatErrorsAtTheEnd('unicorn'));
} catch (error) {
console.log(error.bufferedData);
//=> 'unicorn'
}

concat-stream
?This module accepts a stream instead of being one and returns a promise instead of using a callback. The API is simpler and it only supports returning a string, buffer, or array. It doesn't have a fragile type inference. You explicitly choose what you want. And it doesn't depend on the huge readable-stream
package.
