http-cache

Caching proxy as middleware for Go.

Why?

First, this was part of the job test assessment. But I think it shouldn't go to the trash bin and might be useful for someone. So, generally speaking - Just for fun 😊

Getting Started

Installation

go get -u github.com/vokinneberg/http-cache

Usage

Generic Go middleware

func main() {
    mux := http.NewServeMux()
    mux.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
        w.Header().Set("Content-Type", "application/json")
        w.Write([]byte("{\"hello\": \"world\"}"))
    })

    handler := httpcache.NewDefault().Handler(mux)
    http.ListenAndServe(":8080", handler)
}

Gorilla mux

func main() {
    mux := mux.NewRouter()
    mux.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
        w.Header().Set("Content-Type", "application/json")
        w.Write([]byte("{\"hello\": \"world\"}"))
    })

    handler := httpcache.NewDefault().Handler(mux)
    http.ListenAndServe(":8080", handler)
}

Negroni middleware

func main() {
    mux := http.NewServeMux()

    mux.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
        w.Header().Set("Content-Type", "application/json")
        w.Write([]byte("{\"hello\": \"world\"}"))
    })

    n := negroni.Classic()

    n.Use(httpcache.NewDefault())
    n.UseHandler(mux)
    n.Run(":8080")
}

Roadmap

• Add Unit tests.
• Add benchmarks - I really interested in how efficient this implementation is?
• Add Debug option.
• Make middleware RFC7234 complaint.
  • Add support for Cache-Control header.
• Add more data store adapters such as: Redis, memcached, DynamoDB, etc.
