Gin

Gin is a web framework written in Go. It has a Martini-like API and uses a radix tree router, so routes are matched quickly with a small memory footprint.

You register routes and attach middleware to groups or single routes. Requests pass through the middleware chain before the final handler, which can handle logging, authorisation or compression. Gin can recover from panics so the server keeps running, and it collects errors during a request so middleware can log or report them.

• Radix tree routing with a small memory footprint
• Middleware chains for each route or group
• Route groups for versions and access rules
• JSON validation and built-in JSON, XML and HTML rendering

Go developers building APIs and web services who want a familiar structure and good performance. It suits backend teams that like Martini-style code and want a small, well known framework in their stack.

Gin is open source under the MIT licence and free to use. The project has community discussion forums and a list of known users on its site. As with any Go framework, you need the Go toolchain installed, and you should add your own database and authentication layers.
