into-stream

What is into-stream?

The into-stream npm package allows you to convert various data types into readable streams. This is particularly useful when you need to work with streams but your data is not already in a stream format.

What are into-stream's main functionalities?

Convert String to Stream

This feature allows you to convert a string into a readable stream. The example code converts the string 'Hello, world!' into a stream and pipes it to the standard output.

const intoStream = require('into-stream');
const stream = intoStream('Hello, world!');
stream.pipe(process.stdout);

Convert Buffer to Stream

This feature allows you to convert a Buffer into a readable stream. The example code converts a Buffer containing 'Hello, world!' into a stream and pipes it to the standard output.

const intoStream = require('into-stream');
const buffer = Buffer.from('Hello, world!');
const stream = intoStream(buffer);
stream.pipe(process.stdout);

Convert Array to Stream

This feature allows you to convert an array into a readable stream. The example code converts an array of strings into a stream and logs each chunk to the console.

const intoStream = require('into-stream');
const array = ['Hello', 'world', '!'];
const stream = intoStream(array);
stream.on('data', chunk => console.log(chunk.toString()));

Convert Object to Stream

This feature allows you to convert an object into a readable stream. The example code converts an object into a stream and logs each chunk to the console.

const intoStream = require('into-stream');
const object = { key: 'value' };
const stream = intoStream.object(object);
stream.on('data', chunk => console.log(chunk));

Other packages similar to into-stream

streamifier

The streamifier package also converts various data types into readable streams. It offers similar functionality to into-stream but with a slightly different API. For example, it provides methods like createReadStream for different data types.

from2

The from2 package is another alternative that allows you to create readable streams from various data sources. It is more flexible in terms of stream creation and provides a more manual approach compared to into-stream.

readable-stream

The readable-stream package is a comprehensive implementation of Node.js streams. While it doesn't directly convert data types into streams, it provides the building blocks to create custom streams, offering more control and flexibility.
