formstream

What is formstream?

The formstream npm package is used to create multipart/form-data streams, which are useful for uploading files and data via HTTP requests. It simplifies the process of constructing form data streams, making it easier to handle file uploads in Node.js applications.

What are formstream's main functionalities?

Create a form stream

This feature allows you to create a form stream, add fields and files to it, and then generate the stream for use in an HTTP request.

const formstream = require('formstream');
const form = formstream();
form.field('name', 'value');
form.file('file', '/path/to/file');
form.stream();

Add fields to the form

This feature allows you to add text fields to the form stream. Each field is added with a key-value pair.

const form = formstream();
form.field('username', 'john_doe');
form.field('email', '[e-mail]');

Add files to the form

This feature allows you to add files to the form stream. Each file is added with a key and the file path.

const form = formstream();
form.file('profile_picture', '/path/to/profile.jpg');

Generate the form stream

This feature generates the form stream after adding all the fields and files. The generated stream can then be used in an HTTP request.

const form = formstream();
form.field('username', 'john_doe');
form.file('profile_picture', '/path/to/profile.jpg');
const stream = form.stream();

Other packages similar to formstream

form-data

The form-data package is a module to create readable 'multipart/form-data' streams. It is similar to formstream in that it allows you to construct form data streams for file uploads. However, form-data is more widely used and has more extensive documentation and community support.

multiparty

The multiparty package is a module for parsing multipart/form-data, which is commonly used for file uploads. Unlike formstream, which focuses on creating form data streams, multiparty is used for parsing incoming form data streams. It is useful for handling file uploads on the server side.

busboy

The busboy package is a fast and low-level module for parsing incoming HTML form data. It is similar to multiparty in that it is used for parsing form data streams, but it is known for its performance and efficiency. It is a good choice for handling large file uploads.
