Simplr-Router Preact Middleware

Introduction

This repository contains the Preact middleware needed for running Simplr Router with Preact.

Usage

The example is created on top of Preact cli create default.

import Header from "./header";

import Home from "../routes/home";
import Profile from "../routes/profile";
import SimplrRouter from "@simplr-wc/router";
import SimplrRouterPreactMiddleware from "@simplr-wc/router-preact-middleware";

const routes = [
  {
    path: "/",
    component: Home,
  },
  {
    path: "profile",
    component: Profile,
    routes: [
      {
        path: ":user",
        component: Profile,
      },
    ],
  },
];

const router = new SimplrRouter({ routes });
router.use(SimplrRouterPreactMiddleware());
router.init();

const App = () => (
  <div id="app">
    <Header />
  </div>
);

export default App;

The properties from dynamic routes are accessible from the props of the component.

import { h } from "preact";
import { useEffect, useState } from "preact/hooks";
import style from "./style.css";

// Note: `user` comes from the URL, courtesy of our router
const Profile = ({ user }) => {
  const [time, setTime] = useState(Date.now());
  const [count, setCount] = useState(10);

  useEffect(() => {
    let timer = setInterval(() => setTime(Date.now()), 1000);
    return () => clearInterval(timer);
  }, []);

  return (
    <div class={style.profile}>
      <h1>Profile: {user}</h1>
      <p>This is the user profile for a user named {user}.</p>

      <div>Current time: {new Date(time).toLocaleString()}</div>

      <p>
        <button onClick={() => setCount((count) => count + 1)}>Click Me</button>{" "}
        Clicked {count} times.
      </p>
    </div>
  );
};

export default Profile;
