Types

type App 

type App struct {
	// Config can be used by applications to fetch custom configurations from environment or file.
	Config config.Config // If we directly embed, unnecessary confusion between app.Get and app.GET will happen.
	// contains filtered or unexported fields
}

App is the main application in the gofr framework.

func New 

func New() *App

New creates an HTTP Server Application and returns that App.

func NewCMD 

func NewCMD() *App

NewCMD creates a command line application.

func (*App) AddHTTPService 

func (a *App) AddHTTPService(serviceName, serviceAddress string, options ...service.Options)

AddHTTPService registers HTTP service in container.

func (*App) AddRESTHandlers added in v1.3.0 

func (a *App) AddRESTHandlers(object interface{}) error

func (*App) DELETE 

func (a *App) DELETE(pattern string, handler Handler)

DELETE adds a Handler for http DELETE method for a route pattern.

func (*App) EnableAPIKeyAuth added in v1.1.1 

func (a *App) EnableAPIKeyAuth(apiKeys ...string)

func (*App) EnableAPIKeyAuthWithFunc added in v1.1.1 

func (a *App) EnableAPIKeyAuthWithFunc(validator func(apiKey string) bool)

func (*App) EnableBasicAuth added in v1.1.1 

func (a *App) EnableBasicAuth(credentials ...string)

func (*App) EnableBasicAuthWithFunc added in v1.1.1

func (*App) EnableOAuth added in v1.1.1 

func (a *App) EnableOAuth(jwksEndpoint string, refreshInterval int)

func (*App) GET 

func (a *App) GET(pattern string, handler Handler)

GET adds a Handler for http GET method for a route pattern.

func (*App) Logger added in v1.3.0 

func (a *App) Logger() logging.Logger

func (*App) Metrics added in v0.2.0 

func (a *App) Metrics() metrics.Manager

func (*App) Migrate added in v0.3.0 

func (a *App) Migrate(migrationsMap map[int64]migration.Migrate)

func (*App) POST 

func (a *App) POST(pattern string, handler Handler)

POST adds a Handler for http POST method for a route pattern.

func (*App) PUT 

func (a *App) PUT(pattern string, handler Handler)

PUT adds a Handler for http PUT method for a route pattern.

func (*App) RegisterService 

func (a *App) RegisterService(desc *grpc.ServiceDesc, impl interface{})

RegisterService adds a grpc service to the gofr application.

func (*App) Run 

func (a *App) Run()

Run starts the application. If it is a HTTP server, it will start the server.

func (*App) SubCommand 

func (a *App) SubCommand(pattern string, handler Handler)

SubCommand adds a sub-command to the CLI application. Can be used to create commands like "kubectl get" or "kubectl get ingress".

func (*App) Subscribe added in v1.1.1 

func (a *App) Subscribe(topic string, handler SubscribeFunc)

func (*App) UseMongo added in v1.3.0 

func (a *App) UseMongo(db datasource.Mongo)

type CRUD added in v1.3.0 

type CRUD interface {
	Create
	GetAll
	Get
	Update
	Delete
}

type Context 

type Context struct {
	context.Context

	// Request needs to be public because handlers need to access request details. Else, we need to provide all
	// functionalities of the Request as a method on context. This is not needed because Request here is an interface
	// So, internals are not exposed anyway.
	Request

	// Same logic as above.
	*container.Container
	// contains filtered or unexported fields
}

func (*Context) Bind 

func (c *Context) Bind(i interface{}) error

func (*Context) Trace 

func (c *Context) Trace(name string) trace.Span

Trace returns an open telemetry span. We have to always close the span after corresponding work is done. Usages: 

span := c.Trace("Some Work")
// Do some work here.
defer span.End()

If an entire function has to traced as span, we can use a simpler format: 

defer c.Trace("ExampleHandler").End()

We can write this at the start of function and because of how defer works, trace will start at that line but End will be called after function ends.

Developer Note: If you chain methods in a defer statement, everything except the last function will be evaluated at call time.

type Create added in v1.3.0 

type Create interface {
	Create(c *Context) (interface{}, error)
}

type Delete added in v1.3.0 

type Delete interface {
	Delete(c *Context) (interface{}, error)
}

type ErrCommandNotFound 

type ErrCommandNotFound struct{}

func (ErrCommandNotFound) Error 

func (e ErrCommandNotFound) Error() string

type Get added in v1.3.0 

type Get interface {
	Get(c *Context) (interface{}, error)
}

type GetAll added in v1.3.0 

type GetAll interface {
	GetAll(c *Context) (interface{}, error)
}

type Handler 

type Handler func(c *Context) (interface{}, error)

type Request 

type Request interface {
	Context() context.Context
	Param(string) string
	PathParam(string) string
	Bind(interface{}) error
	HostName() string
}

Request is an interface which is written because it allows us to create applications without being aware of the transport. In both cmd or server application, this abstraction can be used.

type Responder 

type Responder interface {
	Respond(data interface{}, err error)
}

Responder is used by the application to provide output. This is implemented for both cmd and http server application.

type SubscribeFunc added in v1.1.1 

type SubscribeFunc func(c *Context) error

type SubscriptionManager added in v1.1.1 

type SubscriptionManager struct {
	// contains filtered or unexported fields
}

type Update added in v1.3.0 

type Update interface {
	Update(c *Context) (interface{}, error)
}
