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(res *minima.Response, req *minima.Request) {
// getting the id parameter from route
id := req.Param("id")
// instead of adding a param in route, you just need to fetch it
username := req.Query("name")
// get user from database
userdata, err := db.FindUser(id, username)
if err != nil {
// check for errors
res.NotFound().Send("No user found with particular id")
}
// send user data
res.OK().Json(userdata)
})
}
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(res *minima.Response, req *minima.Request) {
userid := req.Param("id")
// check if user id is available
if userid == "" {
res.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 fetch it
userid := req.Query("id")
if userid == "" {
res.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 custom implementation of radix tree which makes it extremely performant. 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
//static file serve methods
File(pth string, dir string) //serves a single static file to route
Static(pth string, dir string) //serves whole directory with specified pth ex /static/main.html
// 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
//Takes http.Handler and appends it to middleware chain
UseRaw(handler func(http.Handler) http.Handler) *minima
// an custom handler when route is not matched
NotFound(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
// Header methods
GetHeader(key string) string // gets a header from response body
SetHeader(key string, value string) *Response // sets a new header to response body
DelHeader(key string) *Response // Deletes a header from response body
CloneHeaders() http.Header // clones all headers of the response body
Setlenght(len string) *Response // sets content length of the response body
SetBaseHeaders() *Response // sets a good stack of base headers for response body
FlushHeaders() // flushes headers
// 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
XML(content interface{}, indent string) //sends data in xml format
Stream(contentType string read io.Reader) // streams content to the route
NoContent(code int)
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
// custom method when there's an error
Error(content interface{}) *Response
// closes io.Writer connection from the route
CloseConn() *Response
// redirects to given url
Redirect(url string) *Response
// sets header status
Status(code int) *Response
//cookie methods
SetCookie(cookie *http.Cookie) *Response // sets a new cookie to the response
SetCookie(cookie *http.Cookie) *Response // clears a cookie to the response
}
type Req interface {
// minima request interface is built on http.Request
// returns param from route
Param(name string) string
// sets a new param to the request instance
SetParam(key string, value) string
//returns query param from route url
Query(key string) string
//returns query params to a string
QueryString() string
//returns raw url.Values
QueryParams() url.Values
//returns the ip of the request origin
IP() string
//returns whether the request is tls or not
IsTLS() bool
//returns whether the request is a socket or not
IsSocket() bool
//returns scheme type of request body
SchemeType() string
//Gets form value from request body
FormValue(key string) string
//Gets all the form param values
FormParams() (url.Values, error)
//Gets file from request
FormFile(key string) (*multipart.FileHeader, error)
//Gets request Multipart form
MultipartForm() (*multipart.Form, error)
// returns path url from the route
Path() string
// returns raw request body
Body() map[string][]string
// finds given key value from body and returns it
BodyValue(key string) []string
// returns instance of minima.IncomingHeader for incoming header requests
Header() *IncomingHeader
// returns route method ex.get,post
Method() string
// Header methods
SetHeader(key string, value string) *Response //sets a new header to request body
//Get a header from request body
GetHeader(key string) string
//Cookie methods
Cookies() []*http.Cookie // gets all cookies from request body
GetCookie(key string) *http.Cookie // gets a specific cookie from request body
}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.
Minima also takes http.Handler while using .UseRaw function and runs it in a chain.
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))
}
app.UseRaw(HttpHandler())If you wanna help grow this project or say a thank you!
