Wirespec

Readable contracts and typesafe wires made easy

Introduction

Wirespec is a typesafe language to specify endpoints and data transfer models that are exchanged between services. These models and endpoints can then be compiled into bindings for a specific language (TypeScript, Java, Kotlin, Scala).

Wirespec can read and convert OpenApiSpecification (OAS) files.

Syntax

Wirespec knows four definitions: refined, enum, type, endpoint.

Refined

type DEFINITION /REGEX/g

Enum

enum DEFINITION {
    ENTRY, ENTRY, ...
}

Type

type DEFINITION {
    IDENTIFIER: REFERENCE
}

Union

type DEFINITION = ENTRY | ENTRY | ...

Endpoint

endpoint DEFINITION METHOD [INPUT_REFERENCE] PATH [? QUERY] [# HEADER] -> {
    STATUS -> REFERENCE
}

Example

todo.ws

type UUID /^[0-9a-fA-F]{8}\b-[0-9a-fA-F]{4}\b-[0-9a-fA-F]{4}\b-[0-9a-fA-F]{4}\b-[0-9a-fA-F]{12}$/g

type Todo {
    id: UUID,
    name: String,
    done: Boolean
}

type TodoInput {
    name: String,
    done: Boolean
}

type Error {
    code: String,
    description: String
}

endpoint GetTodoById GET /todos/{ id: UUID } -> {
    200 -> Todo[]
    404 -> Error
}

endpoint GetTodos GET /todos?{ done: Boolean? }#{ limit: Integer, offset: Integer } -> {    
    200 -> Todo[]
    404 -> Error
}

endpoint CreateTodo POST TodoInput /todos -> {
    200 -> Todo
    404 -> Error
}

endpoint UpdateTodo PUT TodoInput /todos/{id:UUID} -> {
    200 -> Todo
    404 -> Error
}

endpoint DeleteTodo DELETE /todos/{id:UUID} -> {
    200 -> Todo
    404 -> Error
}
