Busboy is a Node.js library that provides a streaming parser for HTML form data, primarily multipart/form-data uploads. It emits events for files and fields so uploads can be processed incrementally without buffering entire requests in memory.

Use cases

• parse multipart form uploads in a node.js http server
• stream large file uploads to disk without loading them into memory
• extract text fields from submitted html forms
• handle file upload endpoints in express or plain node http
• process incoming form-data requests incrementally

When to choose

• you need low-level, memory-efficient streaming parsing of multipart/form-data in node.js
• you want fine-grained control over how uploaded files and fields are handled
• you are building your own upload middleware or framework on top of it

When to avoid

• you want batteries-included upload handling with validation and storage built in (use multer or formidable)
• you are not working with node.js http form data
• you need to parse urlencoded-only forms with simple key-value semantics
