Core web framework v2.0

Core is used for rapid development of enterprise application in Go, including RESTful APIs, web apps and backend services.

It is inspired by Tornado, Sinatra and Koa(node.js). Core has some Go-specific features such as interfaces and struct embedding.

  • auto register router
  • koa(node.js) develop style
  • simple light framework

func D 

func D(f string, args ...any)

func DBType 

func DBType() string

func DefaultErrorHandler 

func DefaultErrorHandler(c Ctx, err error) error

func Delete 

func Delete[S ~[]E, E any](s S, i, j int) S

Delete removes the elements s[i:j] from s, returning the modified slice. Delete panics if s[i:j] is not a valid slice of s. Delete is O(len(s)-j), so if many items must be deleted, it is better to make a single call deleting them all together than to delete one at a time. Delete might not modify the elements s[len(s)-(j-i):len(s)]. If those elements contain pointers you might consider zeroing those elements so that objects they reference can be garbage collected.

Use registers a middleware route that will match requests with the provided prefix (which is optional and defaults to "/"). Also, you can pass another app instance as a sub-router along a routing path. It's very useful to split up a large API as many independent routers and compose them as a single service using Use. The core error handler and any of the core sub apps are added to the application's error handlers to be invoked on errors that happen within the prefix route. 

	app.Use(func(c core.Ctx) error {
	     return c.Next()
	})
	app.Use("/api", func(c core.Ctx) error {
	     return c.Next()
