## What it is
A Node.js library for creating readable multipart/form-data streams, inspired by the XMLHttpRequest-2 FormData interface. It supports appending strings, buffers, and file streams, and can submit forms and file uploads to other web applications.

## Use cases
- upload files to an http endpoint from node
- build multipart/form-data request bodies with streams
- submit forms programmatically to web applications
- append buffers and file streams to a form payload
- mimic browser FormData in nodejs

## When to choose
- you need multipart/form-data uploads in Node.js with stream support
- you want an API matching the browser FormData interface
- you need to upload large files without buffering them in memory

## When to avoid
- you are in a browser and can use the native FormData API
- you only need JSON request bodies
- you are using fetch with built-in FormData support and don't need stream submission

## Facets
- artifact type: library
- maturity: stable
- function: http-client, serialization, file-upload
- domain: web-development, backend, apis, developer-tools
- platform: serverless
- tags: multipart-form-data, file-upload, streams, formdata, npm, nodejs
