@types/concat-stream

Concatenating Buffer objects

This feature allows for concatenating multiple Buffer objects into a single Buffer. The code sample demonstrates how to use concat-stream with TypeScript to concatenate 'Hello', ' ', and 'World' into a single Buffer and log it.

import concat from 'concat-stream';
const write = concat((data: Buffer) => {
  console.log(data);
});
write.write(Buffer.from('Hello'));
write.write(Buffer.from(' '));
write.write(Buffer.from('World'));
write.end();

Concatenating strings

This feature enables the concatenation of string data. The example shows how to specify the encoding as 'string' to ensure that the callback receives a concatenated string instead of a Buffer.

import concat from 'concat-stream';
const write = concat({ encoding: 'string' }, (data: string) => {
  console.log(data);
});
write.write('Hello');
write.write(' ');
write.write('World');
write.end();

Concatenating typed arrays

This functionality allows for the concatenation of typed arrays, such as Uint8Array. The code sample demonstrates concatenating encoded strings into a single Uint8Array and decoding it back to a string for logging.

import concat from 'concat-stream';
const write = concat((data: Uint8Array) => {
  console.log(new TextDecoder().decode(data));
});
write.write(new TextEncoder().encode('Hello'));
write.write(new TextEncoder().encode(' '));
write.write(new TextEncoder().encode('World'));
write.end();
