CrudRouter

CrudRouter is a Rails-inspired extension to Vapor’s routing system that makes it as simple as possible to set up CRUD (Create, Read, Update, Delete) routes for any Model. CrudRouter provides an API very similar to Rails’ resources but with a few extra features including automatic responder generation and type safety.

Installation

Within your Package.swift

dependencies: [
    .package(url: "https://github.com/twof/VaporCRUDRouter.git", from: "1.0.0")
]

and

targets: [
    .target(name: "App", dependencies: ["CrudRouter"]),
]

Usage

Within your router setup (routes.swift in the default Vapor API template)

router.crud(register: Todo.self)

That’s it!

That one line gets you the following routes.

GET     /todo       // returns all Todos
GET     /todo/:id   // returns the Todo with :id
POST    /todo       // create new Todo with provided body
PUT     /todo/:id   // update Todo with :id
DELETE  /todo/:id   // delete Todo with :id

Generated paths default to using lower snake case so for example, if you were to do

router.crud(register: SchoolTeacher.self)

you’d get routes like

GET     /school_teacher
GET     /school_teacher/:id
POST    /school_teacher
PUT     /school_teacher/:id
DELETE  /school_teacher/:id

Path Configuration

If you’d like to supply your own path rather than using the name of the supplied model, you can also do that

router.crud("account", register: User.self)

results in

GET     /account
GET     /account/:id
POST    /account
PUT     /account/:id
DELETE  /account/:id

Nested Relations

Say you had a model User, which was the parent of another model Todo. If you’d like routes to expose all Todos that belong to a specific User, you can do something like this.

router.crud(register: User.self) { controller in
    controller.crud(children: \.todos)
}

results in

GET     /user
GET     /user/:id
POST    /user
PUT     /user/:id
DELETE  /user/:id

GET     /user/:id/todo      // returns all Todos belonging to the User with :id
GET     /user/:id/todo/:id  // returns the Todo with :id belonging to the User with :id
POST    /user/:id/todo      // creates a new Todo belonging to the User with :id
PUT     /user/:id/todo/:id  // updates the Todo with :id belonging to the User with :id
DELETE  /user/:id/todo/:id  // deletes the Todo with :id belonging to the User with :id

within the supplied closure, you can also expose routes for related Parents and Siblings

controller.crud(children: \.todos)
controller.crud(parent: \.todos)
controller.crud(siblings: \.todos)

Including or Excluding Specific Routes

If you’d like to register a Model, but you don’t want every route to be available, you can specify the ones you want, or exclude the ones you don’t.

router.crud(register: Todo.self, .except([.create, .delete])) { controller in
    controller.crud(parent: \.owner, .only([.read]))
}

results in

PUT /todo/:id
GET /todo/:id
GET /todo

GET /todo/:id/tag/:id

Future features

• query parameter support
• PATCH support
• automatically expose relations (blocked by lack of Swift reflection support)
• generate models and rest routes via console command
• Publicable support (potentially blocked by a compiler bug)
• Fine grained per route public return models
