gin-gonic / gin
Gin is a high-performance HTTP web framework written in Go. It provides a Martini-like API but with significantly better performance—up to 40 times faster—thanks to httprouter. Gin is designed for building REST APIs, web applications, and microservices.

About this codebase
Gin is a Go web framework codebase that takes an incoming HTTP/QUIC request plus registered route handlers, runs the request through Gin’s routing and `Context` pipeline (including binding and content negotiation), and produces an executed response via its `Engine` run loops and `Context` response methods. Practically, you use Gin to stand up an application by constructing an `Engine`, adding routes/groups and middleware, and then calling `Run` (or `RunQUIC`) so Gin can parse, bind, dispatch, negotiate formats, and write results back to the client.

120 files and 1,706 symbols in 6 modules, led by Go (98 files) and Makefile (1).
Code health
This codebase scores 6.4 out of 10 for code health, which we rate fair. It also scores maintainability 7.2 and static performance 9.9 out of 10. The three are scored separately and never blended into one number. Risk is concentrated, as it usually is: 2 of 120 files are git hotspots, and they average 3.6 — which is where the fixes pay off most.

Improve what Repowise can see
Add a test coverage report
Without one, Repowise cannot tell tested code from untested code, so every test-related action says “unknown”.
- line coverage
- Unknown, no report

Gin is a high-performance HTTP web framework written in Go. It provides a Martini-like API but with significantly better performance—up to 40 times faster—thanks to httprouter. Gin is designed for building REST APIs, web applications, and microservices. This page is a map of the gin-gonic/gin repository, written primarily in Go, rebuilt from the source each time it is indexed. Repowise parses every symbol, computes a dependency graph, scores per-file code health from complexity, duplication, test coverage and churn, mines git history for hotspots and ownership, and lifts the architectural decisions into documentation you can read here or query through MCP.
The codebase has 120 files and 1,706 symbols in 6 modules, led by Go and Makefile. Code health is 6.4 out of 10, rated fair.
