next-routes-2 v1.5.0

Dynamic Routes for Next.js

Easy to use universal dynamic routes for Next.js

Fork of next-routes with anchor support

• Express-style route and parameters matching
• Request handler middleware for express & co
• Link and Router that generate URLs by route definition

How to use

Install:

npm install next-routes-2 --save

Create routes.js inside your project:

const routes = require("next-routes");

// Name   Page      Pattern
module.exports = routes() // ----   ----      -----
  .add("about") // about  about     /about
  .add("blog", "/blog/:slug") // blog   blog      /blog/:slug
  .add("user", "/user/:id", "profile") // user   profile   /user/:id
  .add("/:noname/:lang(en|es)/:wow+", "complex") // (none) complex   /:noname/:lang(en|es)/:wow+
  .add({ name: "beta", pattern: "/v3", page: "v3" }); // beta   v3        /v3

This file is used both on the server and the client.

API:

• routes.add([name], pattern = /name, page = name)
• routes.add(object)

Arguments:

• name - Route name
• pattern - Route pattern (like express, see path-to-regexp)
• page - Page inside ./pages to be rendered

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);
});

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 route="blog" params={{ slug: "hello-world" }}>
      <a>Hello world</a>
    </Link>
    or
    <Link route="/blog/hello-world">
      <a>Hello world</a>
    </Link>
  </div>
);

API:

• <Link route='name'>...</Link>
• <Link route='name' params={params}> ... </Link>
• <Link route='/path/to/match'> ... </Link>

Props:

• route - Route name or URL to match (alias: to)
• params - Optional parameters for named routes

It generates the URLs 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 hash
    Router.pushRoute("blog", { slug: "hello-world" }, { hash: "intro" });
    // With route URL
    Router.pushRoute("/blog/hello-world");
  }
  render() {
    return (
      <div>
        <div>{this.props.url.query.slug}</div>
        <button onClick={this.handleClick}>Home</button>
      </div>
    );
  }
}

API:

• Router.pushRoute(route)
• Router.pushRoute(route, params)
• Router.pushRoute(route, params, options)

Arguments:

• route - Route name or URL to match
• params - Optional parameters for named routes
• options - 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')({
  Link: require('./my/link')
  Router: require('./my/router')
})
