HashRouter - Javascript

Introduction

HashRouter is a JavaScript library used for client-side routing in a single page application (SPA) using the hash portion of the URL. It is a powerful tool that manages the state of the application in the URL without making any actual requests to the server.

Benefits

• It's lightweight and easy to use.
• It works with any JavaScript framework or library.
• It allows you to manage the application state in the URL, which is a great way to share links or bookmarks with others.
• It enables you to create dynamic URLs with parameters that can be used to display different content on the same page.
• It facilitates the creation of single-page applications, allowing for smoother and faster navigation between pages.

How it Works

The HashRouter library works by listening for changes in the hash portion of the URL and invoking a callback function when the hash changes. The callback function typically updates the state of the application based on the new hash value.

Here is an example of how to use the HashRouter:

import { HashRouter } from "hash-router";

const router = new HashRouter();

router.on("/home", () => {
  // code to display home page
});

router.on("/about", () => {
  // code to display about page
});

router.on("/products/:id", (params) => {
  // code to display specific product page based on id parameter
});

router.start();

In the above example, we create a new instance of the HashRouter class and call its on method to register three route handlers. The first two handlers are for the "/home" and "/about" pages, respectively, and the third handler is for a dynamic URL that includes an "id" parameter.

The start method is called to start listening for changes in the hash portion of the URL and invoke the appropriate route handler when the hash changes.

Conclusion

HashRouter is a powerful and lightweight JavaScript library that enables you to create single-page applications with dynamic URLs. It works with any JavaScript framework or library and allows you to manage the state of the application in the URL. If you are building a single-page application, be sure to check out HashRouter!
