Usage

Strict route example:

const Router = require('@plant/router')

const router = new Router()

router.get('/users/:id', ({res, route}) => {
  // Get params
  route.params.id // -> {id: "1"}
  // Get current path segment
  route.path // '/users/1'
  // Path before router
  route.basePath // '/'
})

Wildcard route with nested router example:

const Router = require('@plant/router')

const router = new Router()

router.use('/posts/*', Router.create((router) => {
  router.get('/:id', async () => {
    // ...
  })

  router.post('/', async () => {
    // ...
  })
}))

API

Router Type

Router allows to filtrate request by HTTP method and URL pattern and to extract values from the URL.

Example

const Router = require('@plant/router')

const router = new Router()

router.get('/users/:id', () => { /* get resource */ })
router.post('/users', () => { /* post resource */ })
router.delete('/users/:id', () => { /* delete resource */ })

Router.Router()

() -> Router

Router constructor has no arguments.

Router.create()

(create: (router: Router) -> void) -> Router

Factory method. Accepts create method as argument which is a function with router configuration logic. Example:

Router.create((router) => {
  router.get('/greet', ({res}) => res.text('Hello World'))
})

Router#use()

(route:String, ...handlers:Handle) -> Router

Method to add handler for any HTTP method.

Router#before()

(...handlers:Handle) -> Router

Add handlers which will be fired before each handler defined by .use, .get, and other route handlers when route params are match route params (route and method).

It can be helpful when you need to prepend each route with expensive computations which should be done only if request matches defined options. It could be user loading or disk reading.

Router#get()

(route:String, ...handlers:Handle) -> Router

Specify route handlers for GET HTTP method.

Example

// Strict route
router.get('/users/:id', () => {})
// Wildcard route
router.get('/posts/*', () => {})

Router#post()

Same as Router#get() but for POST HTTP method.

Router#put()

Same as Router#get() but for PUT HTTP method.

Router#patch()

Same as Router#get() but for PATCH HTTP method.

Router#delete()

Same as Router#get() but for DELETE HTTP method.

Router#head()

Same as Router#get() but for HEAD HTTP method.

Router#options()

Same as Router#get() but for OPTIONS HTTP method.

Router#addRoute()

(method:string|string[], route:string, ...handler:Handle) -> Router

Add route handler and return router instance. Use method to specify HTTP method or methods supported by the route handler.
