Ruty is a simple URL route builder, that supports typing route params and queries string with TypeScript.

Motivation

Whether I am working in the frontend or backend, I always define a set of URLs for API endpoints or page URLs. Therefore, instead of having all these URLs routes spread out within multiple files, I prefer to have them defined in one file then reference them where I need them. Also, while using TypeScript I prefer to have my URLs routes params and queries string typed. That's the reason I created ruty , a tiny library that allows me to define routes with their params and queries strings.

Features

• TypeScript support.
• Typed route params /:param and typed query strings ?query&string.
• No dependencies.
• 100% test coverage.

Installation

npm i ruty

Usage

import { Ruty } from 'ruty'

const { route } = Ruty.configure()

const routes = {
  home: route('/').build(),
  users: route('/users').build(),
  userById: route('/user/:id?created&sort').build(),
}

routes.home()
// '/'
routes.users()
// '/users'
routes.userById({ id: 123 })
// '/user/123'
routes.userById({ id: 123, created: true, sort: 'desc' })
// '/user/123?created&sort=desc'

TypeScript

You can type your route params and queries string with TypeScript by adding generics to the build method as shown below:

import { route } from 'ruty'

Ruty.configure()

const routes = {
  userById: route('/user/:id?created&sort').build<{
    id: number
    created: boolean
    sort: 'asc' | 'desc'
  }>(),
}

routes.userById({ id: 123, created: true, sort: 'desc' })
// '/user/123?created&sort=desc'

Then you will have autocomplete suggestions and type assertion:

Configuration

Any configuration is passed to Ruty.configure(...).

const ruty = Ruty.configure({
  // 👇 Add a prefix to all genrated routes.
  prefix: '/:language',
  // 👇 A function that transform the value for route params.
  paramTransformer: (param, value) => value,
  // 👇 A function that transform the value for query strings.
  queryTransformer: (query, value) => value,
  // 👇 Global route params.
  params: {
    language: () => detectLanguage(),
  },
  // 👇 Global query string.
  query: {
    theme: 'dark',
  },
})
