A Node.js middleware library that compresses HTTP response bodies using gzip, deflate, or brotli. It is designed for use with Express and Connect-style middleware stacks.

Use cases

• compress HTTP responses in an Express app
• serve gzip or brotli-compressed responses based on Accept-Encoding
• reduce bandwidth usage for API responses
• configure compression level and content-type filters
• add response compression middleware to a Connect server

When to choose

• you use Express or Connect and want drop-in response compression
• you need gzip, deflate, and brotli support with configurable options
• you want a small, well-maintained middleware with sensible defaults

When to avoid

• you are not using Node.js or an Express/Connect-style middleware stack
• you need static asset pre-compression rather than on-the-fly compression
• responses are already compressed or served by a reverse proxy that handles compression
