vuex-module-decorators Rawerror Globally

What is Vuex-module-decorators and how does it work?

Vuex-module-decorators is a library that provides decorators and helpers for writing Vuex modules in a more concise and consistent way. It is built on top of the Vuex library and allows you to define your Vuex module as a class with state, getters, mutations, and actions defined as class properties and methods.

The library provides decorators for defining your state, getters, mutations, and actions, making it easier to write code that is more concise and maintainable. For example, the @Action decorator allows you to define an action as a method on your class and automatically registers it in the Vuex store.

Overall, using Vuex-module-decorators can help you write cleaner, more organized code for your Vuex modules, making your application easier to understand and maintain.

Understanding the concept of rawError in Vuex-module-decorators

When working with Vuex, errors can sometimes occur during state management and mutations. The rawError property in Vuex-module-decorators provides a way to handle these errors globally.

By default, when an error occurs in a module mutation, Vuex will throw an error and stop the flow of execution. However, with rawError in Vuex-module-decorators, you can catch the error and handle it in a global error handler.

The rawError property is a callback function that takes three parameters:

  1. error: the error that occurred
  2. vm: the Vue instance that triggered the action
  3. info: a string that describes where the error occurred

With these parameters, you can create a global error handler that logs the error to a server or displays a user-friendly error message.

To use rawError in Vuex-module-decorators, simply define the callback function in your module and set the rawError property to the name of the function:

  stateFactory: true,
  namespaced: true,
  name: 'myModule',
export default class MyModule extends VuexModule {
  setItem(newItem: Item) {

  @Action({rawError: true})
  async addItem(newItem: Item) {
    try {
      await API.addItem(newItem);
    } catch (error) {
      console.error('Error adding item:', error);

  // Global error handler
  rawError(error: Error, vm: Vue, info: string) {
    console.error('Global error handler:', error, vm, info);

Global implications of using rawError in Vuex modules

Using rawError in Vuex modules can have global implications for your application. When rawError is set to true, it allows errors to be thrown and caught in their original form without being wrapped in an Error object. While this can be useful for debugging purposes, it can also lead to some unintended consequences.

One of the biggest implications of using rawError is that it can make error handling more difficult. When errors are thrown and caught in their original form, it can be harder to determine where the error originated from and how to handle it properly. This can lead to a lot of trial and error when trying to fix bugs or implement new features.

Another implication of using rawError is that it can make your code less portable. If other developers are using libraries or frameworks that don’t support rawError, they may have trouble integrating your code with theirs. This can lead to compatibility issues that can be difficult to resolve.

Finally, using rawError can make your code less secure. Because rawError allows errors to be thrown and caught in their original form, it can sometimes reveal sensitive information such as file paths or database credentials. This can be a major security risk if your code is running in a public environment.

In conclusion, while rawError can be useful in certain situations, it’s important to consider the global implications of using it in your Vuex modules. Before using rawError, make sure you understand the potential consequences and weigh them against the benefits it may provide.

Practical examples of using rawError in Vuex-module-decorators

When working with Vuex and Vuex-module-decorators, it’s important to handle errors properly. One of the ways to do this is by using the rawError option in your actions.

Here are some practical examples of how to use rawError:

  1. Logging errors: You can use rawError to log any errors that occur in your actions. For example:
@Action({ rawError: true })
async fetchData() {
  try {
    // fetch data here
  } catch (error) {
  1. Custom error handling: You can use rawError to handle errors in a custom way. For instance, you could display a friendly error message to your users.
@Action({ rawError: true })
async fetchData() {
  try {
    // fetch data here
  } catch (error) {
    this.context.commit("setError", "Oops, something went wrong!")
  1. Forwarding errors: If you’re using a plugin to handle errors globally, you can forward errors to it using rawError.
@Action({ rawError: true })
async fetchData() {
  try {
    // fetch data here
  } catch (error) {
    this.context.dispatch("handleError", error)

In conclusion, rawError is a powerful option in Vuex-module-decorators that can help you handle errors more effectively. Whether you’re logging errors, customizing error messages, or forwarding errors to a global handler, it’s worth taking advantage of this feature.

Common pitfalls to avoid when using rawError globally in Vuex

When working with Vuex, it’s essential to handle errors that may occur during actions or mutations. To make it easier, Vuex provides a global error handler called rawError, which is executed whenever an error is thrown within a Vuex action or mutation. However, there are some common pitfalls that you need to avoid when using rawError globally in Vuex.

1. Overreliance on rawError
While rawError can be helpful in handling errors globally, it’s not always the best solution. You may end up relying too much on rawError and not properly handle the errors within the actions or mutations themselves. It’s essential to properly handle errors at the source before passing them to rawError.

2. Inconsistent error handling
Using rawError globally can make error handling more consistent across your Vuex store. However, it’s crucial to maintain consistency in how you handle errors. Make sure you’re using the same error handling approach throughout your actions, mutations, and components to avoid confusion and potential bugs.

3. Muting errors
One common mistake is muting errors by not re-throwing them within the global error handler. If you don’t re-throw an error, it won’t be caught by other error handlers or debugging tools, making it harder to debug issues. Always make sure to re-throw the error within rawError.

4. Not providing enough details
When an error occurs, it’s essential to provide enough details to help identify the issue and fix it. Make sure to log the error information along with any additional context to provide a clear picture of what happened. Avoid delivering cryptic messages or hiding information within rawError.

Overall, while rawError can be helpful in handling errors globally, it’s essential to handle errors at the source and maintain consistency in error handling approach. Avoid the commonly seen pitfalls to make sure that your rawError is effective in debugging your Vuex store.

Best practices for optimizing the use of rawError in Vuex modules

When working with Vuex modules, it’s essential to properly handle errors to ensure the stability and reliability of your application. The rawError option provides an opportunity to catch errors in an asynchronous action and handle them in a way that suits your needs. Here are some best practices for optimizing the use of rawError in Vuex modules:

  1. Catch Errors in Asynchronous Actions: Async actions often include the possibility of errors occurring. This is where rawError comes in handy. Ensure that all async actions in your Vuex modules have a try-catch block to catch any errors that may occur.
  2. Use rawError as a Computed Property: Instead of using rawErrors as a property in your component, use it as a computed property to help organize your code. This way, you can avoid passing it around as props and use it directly in your template.
  3. Avoid rawError in Global Vuex Configuration: While the rawError option is helpful in handling errors, it’s not recommended to use it globally in your Vuex configuration. Doing so can make it challenging to determine which module generated the error.
  4. Keep Error Handling Consistent: Keep your error handling consistent across all your Vuex modules. Define a specific approach for handling errors in your application, and stick to it as closely as possible.

By following these best practices, you can optimize the use of rawError in your Vuex modules effectively. Doing so will make it easier to handle errors and improve the reliability of your application.Here’s the HTML code for the content:

Conclusion: Is using rawError globally in Vuex worth it?

After analyzing the advantages and disadvantages of using rawError globally in Vuex, it ultimately comes down to the specific requirements of your project.

The main advantage of using rawError globally in Vuex is the ability to handle all errors in a centralized location. This can greatly simplify error handling and improve code maintainability. Additionally, it can provide a better user experience by displaying consistent error messages throughout the application.

However, there are also some drawbacks to consider. Global error handling can sometimes make it difficult to debug errors if the root cause is not immediately visible. It can also potentially introduce unexpected behavior if not implemented correctly.

Overall, using rawError globally in Vuex can be a useful tool for handling errors in a large-scale application. However, it should be carefully considered and implemented with caution to ensure the best results for your specific project.
