Solved: router push

The world of web development presents various challenges that need practical solutions. One of these challenges is navigation through different components or pages in applications. This article focuses on one such technical problem- the router push. The router push is, in essence, a way to navigate between pages without a full page refresh thus creating a seamless user experience. This is typically handled through the router in an application, and the push method found on the history object.

The difficulty in implementing the router push correctly lies in managing the state and the history of the browser. When dealing with large applications, understanding how navigation impacts the state of your application is critical.

Let’s dive into router push, how to implement it correctly, and how it interacts with different libraries or functions.

The solution to Router Push

To successfully implement a router push in JavaScript, you will likely be using one of the popular routing libraries, such as React Router or Vue Router.

Implementing router push with these libraries involves calling the push function on the router object, and passing in the URL that you want to navigate to. This function will push a new entry onto the history stack, hence the name “router push”.

import { useHistory } from "react-router-dom";

function Example() {
  const history = useHistory();

  function handleClick() {

  return (
    <button type="button" onClick={handleClick}>
      Go home

Step-by-step breakdown of Router Push

Let’s start at the beginning. The `useHistory` function, which is a hook provided by React Router, gives you access to the history instance that you may use to navigate.

  • First, we import `useHistory` function from ‘react-router-dom’.
  • Inside the component, we call `useHistory` and it gives us an instance of the history object. We assign this object to the `history` variable.
  • Then we create a function, `handleClick`, which when executed will call the `push` function on our `history` object.
  • The string ‘/home’ is passed as an argument to `push`, indicating the route to navigate to.
  • This `handleClick` function is then attached to the `onClick` event of a button. So whenever the button is clicked in our application, the app will navigate to the home route.

Understanding related libraries, functions, and concepts

Understanding how the router push operates is linked with understanding other key concepts and libraries in web development.

The browser history object: It’s the stepping stone to comprehend router push in JavaScript. It provides a stack of URLs visited by the user, allowing you to move back and forth over the user’s history.

React and React Router: One of the mostly used libraries that gives you the ability to control your navigation. It uses the concept of dynamic routing which defers route configuration until runtime.

Vue and Vue Router: These libraries also offer dynamic routing but with a simpler API. The Vue Router is deeply integrated with Vue.js core to make building Single Page Applications with Vue.js a breeze.

By mastering these concepts and tools, you are leveling up your ability to build efficient and user-friendly web applications. A firm grasp of these technologies will surely enhance your problem-solving skills in web development.
