Accessing the Vuex Store Outside of Vue Components: A Guide for Rails Developers

In the dynamic world of web development, managing state effectively is paramount—especially when using frameworks like Vue.js combined with Vuex for state management. However, developers often face hurdles when attempting to access the Vuex store outside of Vue components, particularly in environments that do not support ES6 syntax or import statements. This guide dives into how to work around this limitation, specifically for those using Rails 5 without Webpack, by leveraging global JavaScript objects to interact with the Vuex store.

The Problem

You might be working with a Vue setup where Vuex is used to manage the state but find yourself needing to access the Vuex store's state or mutations in an external JavaScript file. For instance, in a Rails application, you're unable to use the standard import statement due to the limitations of the environment.

Key Queries

Is it possible to access Vuex stores outside of Vue components while using ES5 JavaScript? The short answer is: Yes, it is indeed possible!

The Solution: Using Global Variables

In an environment like Rails, where ES5 is the standard and import statements are not allowed, the best way to access your Vuex store is to define it as a global JavaScript object. Here’s a straightforward guide to achieving that.

Step 1: Define the Vuex Store

You should start by creating your Vuex store in your JavaScript files. Here’s how you can set it up:

Step 2: Include Vue and Vuex

Ensure that you correctly include Vue and Vuex in your application by adding the following lines in your application.js file:

Step 3: Access the Store as a Global Object

In this setup, store becomes a global JavaScript object. You can access its state and methods as you would with any other JavaScript object. Here are some examples of how to use it:

Practical Example

In practical terms, you might have situations where an asynchronous operation, like a webhook call, requires you to access the store. Here’s how that could look:

In this case, as new messages are received through the webhook, you're able to update the state of your application dynamically without needing to rely on components to carry that information.

Conclusion

Accessing the Vuex store outside of Vue components is entirely feasible in a Rails environment, even without the modern conveniences of ES6. By leveraging global objects, you can manage your application’s state more effectively. With this approach, you gain the flexibility to interact with your state management solutions cohesively, even while working in a more traditional JavaScript setup.

Now that you know how to handle Vuex stores in this manner, you can ensure your frontend remains robust and responsive—regardless of the constraints of your working environment.
