Dynamic Routes with localization for Next.js
Based on Next-Routes with these changes:
- No support for unnamed routes
- Route can be added only by name, locale and pattern (and optionally page) or options object
Link
andRouter
generate URLs only by route definition (name + params)- URLs are prefixed with locale (ie. /en/about)
- Routes can have data object (if you generate routes dynamically you can pass custom data there)
- default RequestHandler set locale and nextRoute properties on request (you can get data with
req.nextRoute.data
)
How to use
Install:
npm install next-routes-with-locale --save
Create routes.js
inside your project:
const routes = module.exports = require('next-routes-with-locale')({ locale: 'en' })
routes
.add('about', 'en', '/about')
.add('blog', 'en', '/blog/:slug')
.add('blog', 'en', '/blog/:slug', {myCustom: 'data'})
.add('user', 'en', '/user/:id', 'profile', {myCustom: 'data'})
.add({name: 'beta', locale: 'en', pattern: '/v3', page: 'v3'})
.add('about', 'cs', '/o-projektu')
.add('blog', 'cs', '/blog/:slug')
.add('user', 'cs', '/uzivatel/:id', 'profile')
.add({name: 'beta', locale: 'cs', pattern: '/v3', page: 'v3'})
This file is used both on the server and the client.
API:
routes.add(name, locale, pattern = /name, page = name, data)
routes.add(object)
Arguments:
name
- Route name (e.g.about
)locale
- Locale of the route (e.g.fr
)pattern
- Route pattern (e.g./about
; like express, see path-to-regexp)page
- Page inside./pages
to be rendered; can be ommited (it takes by default the route name as the page name)data
- Custom data object
The page component receives the matched URL parameters merged into query
export default class Blog extends React.Component {
static async getInitialProps ({query}) {
// query.slug
}
render () {
// this.props.url.query.slug
}
}
On the server
// server.js
const next = require('next')
const routes = require('./routes')
const app = next({dev: process.env.NODE_ENV !== 'production'})
const handler = routes.getRequestHandler(app)
// With express
const express = require('express')
app.prepare().then(() => {
express().use(handler).listen(3000)
})
// Without express
const {createServer} = require('http')
app.prepare().then(() => {
createServer(handler).listen(3000)
})
RequestHandler automatically sets req.locale to locale of matched route so you can use it in your app.
Optionally you can pass a custom handler, for example:
const handler = routes.getRequestHandler(app, ({req, res, route, query}) => {
app.render(req, res, route.page, query)
})
Make sure to use server.js
in your package.json
scripts:
"scripts": {
"dev": "node server.js",
"build": "next build",
"start": "NODE_ENV=production node server.js"
}
On the client
Import Link
and Router
from your routes.js
file to generate URLs based on route definition:
Link
example
// pages/index.js
import {Link} from '../routes'
export default () => (
<div>
<div>Welcome to Next.js!</div>
<Link href='blog' params={{slug: 'hello-world'}}>
<a>Hello world</a>
</Link>
or
<Link href='blog' locale='cs' params={{slug: 'ahoj-svete'}}>
<a>Hello world</a>
</Link>
</div>
)
API:
<Link href='name'>...</Link>
<Link href='name' locale='locale'>...</Link>
<Link href='name' params={params}> ... </Link>
<Link href='name' locale='locale' params={params}> ... </Link>
Props:
href
- Route name to match (the name, not the pattern)params
- Optional parameters
It generates the URLs prefixed with the locale for href
and as
and renders next/link
. Other props like prefetch
will work as well.
Router
example
// pages/blog.js
import React from 'react'
import {Router} from '../routes'
export default class Blog extends React.Component {
handleClick () {
// With route name and params
Router.pushRoute('blog', {slug: 'hello-world'})
// With route name and params and explicit locale
Router.pushRoute('blog', {slug: 'hello-world'}, 'en')
}
render () {
return (
<div>
<div>{this.props.url.query.slug}</div>
<button onClick={this.handleClick}>Home</button>
</div>
)
}
}
API:
Router.pushRoute(route, params)
- automatically get current localeRouter.pushRoute(route, params, locale)
Router.pushRoute(route, params, locale, options)
Arguments:
route
- Route namelocale
- Route localeparams
- Optional parameters for named routesoptions
- Passed to Next.js
The same works with .replaceRoute()
and .prefetchRoute()
It generates the URLs and calls next/router
Optionally you can provide custom Link
and Router
objects, for example:
const routes = module.exports = require('next-routes-with-locale')({
Link: require('./my/link'),
Router: require('./my/router')
})
