Generouted + React Router + Type-safety

Docs

Check out generouted's main docs for the features, conventions and more.

How

This integration is based on a Vite plugin to generate routes types for React Router with generouted conventions. The output is saved by default at src/router.ts and gets updated by the add/change/delete at src/pages/*.

Getting started

In case you don't have a Vite project with React and TypeScript, check Vite documentation to start a new project.

Installation

pnpm add @generouted/react-router react-router-dom

Setup

// vite.config.ts

import { defineConfig } from 'vite'
import react from '@vitejs/plugin-react'
import generouted from '@generouted/react-router/plugin'

export default defineConfig({ plugins: [react(), generouted()] })

Usage

// src/main.tsx

import { createRoot } from 'react-dom/client'
import { Routes } from '@generouted/react-router'
// import { Routes } from '@generouted/react-router/lazy' // route-based code-splitting

createRoot(document.getElementById('root')!).render(<Routes />)

Adding pages

Add the home page by creating a new file src/pages/index.tsx /, then export a default component:

// src/pages/index.tsx

export default function Home() {
  return <h1>Home</h1>
}

Optional root layout at pages/_app.tsx

// src/pages/_app.tsx

import { Outlet } from 'react-router-dom'

export default function App() {
  return (
    <section>
      <header>
        <nav>...</nav>
      </header>

      <main>
        <Outlet />
      </main>
    </section>
  )
}

Type-safe navigation

Autocompletion for Link, useNavigate, useParams and more exported from src/router.ts

// src/pages/index.tsx
import { Link, useNavigate, useParams } from '../router'

export default function Home() {
  const navigate = useNavigate()

  // typeof params -> { id: string; pid?: string }
  const params = useParams('/posts/:id/:pid?')

  // typeof params to be passed -> { id: string; pid?: string }
  const handler = () => navigate('/posts/:id/:pid?', { params: { id: '1', pid: '0' } })

  return (
    <div>
      {/** ✅ Passes  */}
      <Link to="/" />
      <Link to="/posts/:id" params={{ id: '1' }} />
      <Link to="/posts/:id/:pid?" params={{ id: '1' }} />
      <Link to="/posts/:id/:pid?" params={{ id: '1', pid: 0 }} />

      {/** 🔴 Error: not defined route  */}
      <Link to="/not-defined-route" />

      {/** 🔴 Error: missing required params */}
      <Link to="/posts/:id" />

      <h1>Home</h1>
    </div>
  )
}

Type-safe global modals

Although all modals are global, it's nice to co-locate modals with relevant routes.

Create modal routes by prefixing a valid route file name with a plus sign +. Why +? You can think of it as an extra route, as the modal overlays the current route:

// src/pages/+login.tsx

import { Modal } from '@/ui'

export default function Login() {
  return <Modal>Content</Modal>
}

To navigate to a modal use useModals hook exported from src/router.ts:

// src/pages/_app.tsx

import { Outlet } from 'react-router-dom'

import { useModals } from '../router'

export default function App() {
  const modals = useModals()

  return (
    <section>
      <header>
        <nav>...</nav>
        <button onClick={() => modals.open('/login')}>Open modal</button>
      </header>

      <main>
        <Outlet />
      </main>
    </section>
  )
}

With useModals you can use modals.open('/modal-path') and modals.close(), and by default it opens/closes the modal on the current active route.

Both methods come with React Router's navigate() options with one prop added at, for optionally navigating to a route while opening/closing a modal, and it's also type-safe!

  • modals.open(path, options)
  • modals.close(options)

at should be also a valid route path, here are some usage examples:

  • modals.open('/login', { at: '/auth', replace: true })
  • modals.open('/info', { at: '/invoice/:id', params: { id: 'xyz' } })
  • modals.close({ at: '/', replace: false })
