Goa Design Wizard-API and service design tool

Example

Type("Person", func() { Attribute("name", String) })

Scenario

This function defines a reusable type, such as `Person`, which can be used across different services or methods for payloads or responses. By centralizing type definitions, you avoid redundancy and ensure consistency in how data is handled.

Example

Method("Multiply", func() { Payload(func() { Attribute("a", Int) Attribute("b", Int) Required("a", "b") }) Result(Int) HTTP(func() { GET("/multiply/{a}/{b}") Response(StatusOK) }) })

Scenario

The `Method` function allows you to define service endpoints that perform specific actions, like multiplying two numbers. This method can be defined with various transports (HTTP, gRPC), making it versatile for real-world API development.

Example

Error("InvalidArgument", String, "Invalid input provided")

Scenario

Goa allows you to define custom error types, making it easier to handle errors consistently across your service. In case of invalid input, the `InvalidArgument` error can be thrown, and clients will receive a structured error response.
