toimtoimtoim 6ef5f77bf2 WIP: logger examples
WIP: make default logger implemented custom writer for jsonlike logs
WIP: improve examples
WIP: defaultErrorHandler use errors.As to unwrap errors. Update readme
WIP: default logger logs json, restore e.Start method
WIP: clean router.Match a bit
WIP: func types/fields have echo.Context has first element
WIP: remove yaml tags as functions etc can not be serialized anyway
WIP: change BindPathParams,BindQueryParams,BindHeaders from methods to functions and reverse arguments to be like DefaultBinder.Bind is
WIP: improved comments, logger now extracts status from error
WIP: go mod tidy
WIP: rebase with 4.5.0
WIP:
* removed todos.
* removed StartAutoTLS and StartH2CServer methods from `StartConfig`
* KeyAuth middleware errorhandler can swallow the error and resume next middleware
WIP: add RouterConfig.UseEscapedPathForMatching to use escaped path for matching request against routes
WIP: FIXMEs
WIP: upgrade golang-jwt/jwt to `v4`
WIP: refactor http methods to return RouteInfo
WIP: refactor static not creating multiple routes
WIP: refactor route and middleware adding functions not to return error directly
WIP: Use 401 for problematic/missing headers for key auth and JWT middleware (#1552, #1402).
> In summary, a 401 Unauthorized response should be used for missing or bad authentication
WIP: replace `HTTPError.SetInternal` with `HTTPError.WithInternal` so we could not mutate global error variables
WIP: add RouteInfo and RouteMatchType into Context what we could know from in middleware what route was matched and/or type of that match (200/404/405)
WIP: make notFoundHandler and methodNotAllowedHandler private. encourage that all errors be handled in Echo.HTTPErrorHandler
WIP: server cleanup ideas
WIP: routable.ForGroup
WIP: note about logger middleware
WIP: bind should not default values on second try. use crypto rand for better randomness
WIP: router add route as interface and returns info as interface
WIP: improve flaky test (remains still flaky)
WIP: add notes about bind default values
WIP: every route can have their own path params names
WIP: routerCreator and different tests
WIP: different things
WIP: remove route implementation
WIP: support custom method types
WIP: extractor tests
WIP: v5.0.x proposal
over v4.4.0
