Detecting Localstorage Changes in Vue.js and JavaScript

In modern web development, especially when creating applications with frameworks like Vue.js, maintaining responsiveness and dynamic content is crucial. One common scenario is when users select different workspace domains, often leading to a change in API base URLs. This can become more complex when it comes to managing base URLs that are stored in localStorage. Let's delve into the problem of how we can detect localStorage changes and dynamically reassign values without needing to reload the page.

The Problem

Imagine you have an application where users can choose between multiple domains upon login. For instance, your application might offer three domain choices: dev, demo, and sandbox. When a user selects a domain, the application's Boot.js file should update the API base URL accordingly. However, the challenge arises because the base URL does not reflect changes made to the localStorage until the page is refreshed, which is not ideal for user experience.

Example Scenario:

User logs in and selects "dev" as their domain.

The application sets the base URL in localStorage.

However, the baseURL variable in Boot.js retains its old value until the page is reloaded.

The Solution: Dynamic Base URL Updates

The solution to this issue involves creating a function that updates the baseURL dynamically whenever the localStorage value is changed. Here’s how you can implement it:

Step-by-Step Implementation

Modify your Boot File:

We'll extend the existing boot file with a function that allows for updating the base path dynamically.

Integrate the Function in Your Vue Files:

After importing the changeBasepath function in your Vue components, implement it where localStorage is updated:

Conclusion

With this approach, you can effectively manage state changes tied to localStorage, enabling your application to respond immediately to user actions. By implementing a function to update the base URL dynamically based on current selections, you improve user experience significantly—no page refresh required!

In summary, this solution allows your app to become more interactive and utilizes modern best practices regarding state management in web applications, particularly using Vue.js. Happy coding!
