}- Reliable - great modular API for building great server side applications
- Compatible with net/http - use your plain old middlewares written in plain old
net/http - Lightweight - clocked in ~1000 loc
- No Dependency - just your plain old go standard libraries
- Great Documentation - best in class precise documentation
- Auto Docs - docgen for generating all of your routing docs from router to json or markdown files
Minima's name is inspired by the word minimal and is the motivation for building this framework. As a Golang developer, I was struggling to learn it in my early days due to the steeper learning curve while using net/http.
Also while checking out some other alternate frameworks, I found out that something like fiber wasn't compatible with net/http modules like gqlgen and other middlewares.
Minima solves this problem as it has a very narrow learning curve as well as a robust structure that supports all net/http modules and other middlewares without compromising performance.
Here are some basic examples related to routing and params:
func UserGetRouter() *minima.Router {
// router instance which would be used by the main router
router := minima.NewRouter()
return router.Get("/user/:id/?", func(response *minima.Response, request *minima.Request) {
// getting the id parameter from route
id := request.GetParam("id")
// as query params are not part of the request path you will need to add a query to initialize them
username := request.GetQuery("name")
// get user from database
userdata, err := db.FindUser(id, username)
if err != nil {
panic(err)
// check for errors
response.Status(404).Send("No user found with particular id")
}
// send user data
response.Json(userdata).Status(200)
})
}
func main() {
// main minima instance
app := minima.New()
// UseRouter method takes minima.router as a param
// it appends all the routes used in that specific router to the main instance
app.UseRouter(UserGetRouter())
// running the app at port 3000
app.Listen(":3000")
}func main() {
app := minima.New()
app.Get("/getuser/:id", func(response *minima.Response, request *minima.Request) {
userid := request.GetParam("id")
// check if user id is available
if userid == "" {
response.Error(404, "No user found")
panic("No user id found in request")
}
fmt.Print(userid)
//Will print 20048 from router /getuser/200048
})
}func main() {
app := minima.New()
app.Get("/getuser/?", func(response *minima.Response, request *minima.Request) {
// query params work a bit differently
// instead of adding a param in route, you just need to add a query and fetch the param
userid := request.GetQuery("id")
if userid == "" {
response.Error(404, "No user found")
panic("No user id found in request")
}
fmt.Print(userid)
// the above will print 20048 from router /getuser?id=20048
})
}Minima is based on a looping system which loops through routes and matches the regex of requested route. The router itself is fully compatible with net/http
type Minima interface {
// Minima interface is built over net/http so every middleware is compatible with it
// initializes net/http server with address
Listen(address string) error
// main handler interface
ServeHTTP(w http.ResponseWriter, q *http.Request)
// main router methods
Get(path string, handler ...Handler) *minima
Patch(path string, handler ...Handler) *minima
Post(path string, handler ...Handler) *minima
Put(path string, handler ...Handler) *minima
Options(path string, handler ...Handler) *minima
Head(path string, handler ...Handler) *minima
Delete(path string, handler ...Handler) *minima
// takes middlewares as a param and adds them to routes
// middlewares initializes before route handler is mounted
Use(handler Handler) *minima
// mounts routes to specific base path
Mount(basePath string, router *Router) *minima
// takes minima.Router as param and adds the routes from router to main instance
UseRouter(router *Router) *minima
// works as a config for minima, you can add multiple middlewares and routers at once
UseConfig(config *Config) *minima
// shutdowns the net/http server
Shutdown(ctx context.Context) error
// prop methods
SetProp(key string, value interface{}) *minima
GetProp(key string) interface{}
}Both response and request interfaces of minima are written in net/http so you can use any of your old route middlewares in minima out of the box without any hassle.
type Res interface {
// response interface is built over http.ResponseWriter for easy and better utility
// returns minima.OutgoingHeader interface
Header() *OutgoingHeader
// utility functions for easier usage
Send(content string) *Response //send content
WriteBytes(bytes []byte) error //writes bytes to the page
Json(content interface{}) *Response //sends data in json format
Error(status int, str string) *Response
// this functions returns http.ResponseWriter instance which means you could use any of your alrady written middlewares in minima!
Raw() http.ResponseWriter
// renders an html file with data to the page
Render(path string, data interface{}) *Response
// redirects to given url
Redirect(url string) *Response
// sets header status
Status(code int) *Response
}
type Req interface {
// minima request interface is built on http.Request
// returns param from route url
GetParam(name string) string
// returns path url from the route
GetPathURL() string
// returns raw request body
Body() map[string][]string
// finds given key value from body and returns it
GetBodyValue(key string) []string
// returns instance of minima.IncomingHeader for incoming header requests
Header() *IncomingHeader
// returns route method ex.get,post
Method() string
// gets query params from route and returns it
GetQuery(key string) string
}Minima's middlewares are written in its own custom res and req interfaces in accordance with the standard libraries maintained by Go. You can use res.Raw() to get the http.ResponseWriter instance and req.Raw() to getthe http.Request instance, meaning all community written middlewares are compatible with Minima.
Here is an example of standard net/http middleware being used with minima:
func MyMiddleWare(res *minima.Response, req *minima.Request) {
w := res.Raw() // raw http.ResponseWriter instance
r := req.Raw() // raw http.Request instance
// your normal net/http middleware
w.Write([]byte(r.URL.Path))
