Unlock the Power of Vuex Plugins

Demystifying Vuex Plugins

A Vuex plugin is simply a function that receives the store as its only argument. Think of it as a trigger that’s called when a specific type of mutation or action is executed in Vuex. This allows you to tap into the inner workings of your application and respond to changes in real-time.

Subscribing to Mutation Hooks

When working with mutation hooks, remember that plugins can’t directly mutate the state. Instead, they trigger changes by committing Vuex mutations. The Mutations Hook exposes two crucial attributes: mutation.type and mutation.payload. These allow you to determine the name of the mutation or action being triggered and retrieve the data to be committed.

const examplePlugin = (store) => {
  store.subscribe((mutation) => {
    console.log(mutation.type); // Get the type of mutation
    console.log(mutation.payload); // Get the payload of the mutation
  });
};

Building a Custom Vuex Plugin

Let’s create a custom Vuex plugin that notifies a Slack channel of any errors when committing our state. We’ll start by creating a plugin class and a Vuex mutation called STORE_ERRORS. This mutation will store errors in our state or display an error alert using packages like SweetAlert.

class SlackNotifier {
  install(store) {
    store.subscribe((mutation) => {
      if (mutation.type === 'STORE_ERRORS') {
        this.errorSlackAlert(mutation.payload);
      }
    });
  }

  errorSlackAlert(error) {
    const slackMessage = `Error: ${error.message}`;
    this.postToSlack(slackMessage);
  }

  postToSlack(message) {
    // Post the message to the Slack webhook
  }
}

Taking Your Vue Apps to the Next Level

By now, you should have a deeper understanding of Vuex plugins and the know-how to build your own custom plugins. With this knowledge, you can take your Vue apps to the next level by monitoring and tracking Vue mutations in production.

Debugging Vue.js Applications Made Easy

Imagine being able to record everything that happens in your Vue apps, including network requests, JavaScript errors, performance problems, and more. This allows you to aggregate and report on what state your application was in when an issue happened, making it easier to debug and modernize your Vue apps.
