What is read-all-stream?
The 'read-all-stream' npm package is a utility that allows you to read all data from a stream until the end. It is particularly useful for handling streams in Node.js, such as reading data from files, HTTP responses, or any other stream-based data source.
What are read-all-stream's main functionalities?
Read all data from a stream
This feature allows you to read all data from a stream until the end. In this example, it reads the entire content of 'example.txt' and logs it to the console.
const readAllStream = require('read-all-stream');
const fs = require('fs');
const stream = fs.createReadStream('example.txt');
readAllStream(stream, 'utf8', (err, data) => {
if (err) throw err;
console.log(data);
});
Read all data from a stream with a promise
This feature allows you to read all data from a stream using a promise. It provides a more modern approach to handling asynchronous operations. In this example, it reads the entire content of 'example.txt' and logs it to the console.
const readAllStream = require('read-all-stream');
const fs = require('fs');
const stream = fs.createReadStream('example.txt');
readAllStream(stream, 'utf8').then(data => {
console.log(data);
}).catch(err => {
console.error(err);
});
Other packages similar to read-all-stream
concat-stream
The 'concat-stream' package is similar to 'read-all-stream' in that it also allows you to read all data from a stream. However, 'concat-stream' is more versatile as it can handle different types of data (strings, Buffers, arrays, etc.) and provides a simpler API for concatenating stream data.
get-stream
The 'get-stream' package is another alternative that provides similar functionality. It allows you to get the entire content of a stream as a string, buffer, or array. 'get-stream' also supports promises and async/await, making it a modern and flexible choice for handling streams.
stream-to-array
The 'stream-to-array' package converts a stream into an array of its data chunks. This can be useful if you need to process each chunk individually after reading the entire stream. It provides a different approach compared to 'read-all-stream' by focusing on chunk-based processing.

Read stream to buffer or string
Install
$ npm install --save read-all-stream
Usage
var read = require('read-all-stream');
var stream = fs.createReadStream('index.js');
read(stream).then(function (data) {
console.log(data.length);
});
read(stream, 'utf8', function (err, data) {
console.log(data.length);
});
API
read(stream, [options], [callback])
If callback is omitted, Promise will be returned.
stream
Required
Type: Stream
Event emitter, which data
events will be consumed.
options
Type: object
or string
If type of options
is string
, then it will be used as encoding.
If type is Object
, then next options are available:
options.encoding
Type: string
, null
Default: 'utf8'
Encoding to be used on toString
of the data. If null, the body is returned as a Buffer.
callback(err, data)
Will be called after stream is read.
err
Error
object (if error
event happens).
data
