What are the Best Vuejs Practices of 2021

Vuejs is considered one of the trendiest frameworks with interesting patterns, vast libraries, and outstanding community support for front-end development. As you all know, Vue.js is growing rapidly from the last few years as a javascript-based framework.

There are many reasons behind this, including the simplicity of the framework, easy integrations, user-friendliness, fewer restrictions. These reasons have helped Vue.js to compete with Angular and React as well. It seems that Vue is on par with Angular and React in many aspects.

So let's examine some of the Vue best practices

1. Make sure to use the key inside v-for:

Without Keys, there's no surety about how DOM elements can appear, so we can say that key attributes can help the app be more predictable and persistent. There isn't assurance about their predictable behaviors because small changes can affect the data. But, if you maintain a unique key for each component, then it's easy to predict how Vue applications will handle DOM manipulation.

2. Use actions:

It becomes much more convenient to fetch the data and provide a reusability and encapsulation level when you use API calls and commit to the data correctly.

You will be able to fetch, commit and return, with no duplicate code than the dispatcher whenever you are required to fetch the same web page in different places.

If I am required to apply the same logic when the page has already been fetched, you must use the same reason, which will decrease the load on the server, and I am sure that it will work everywhere.

It is so convenient to track actions into the Mixpanel events, and on the other hand, the code base is easy to maintain. Trust me; you will have a sense of satisfaction working this way.

3. Naming commits- follow a single convention:

You will be required to browse the history of the components if you or your team members have not followed the same convention to name their commits; it will become critical to identify and understand what each does once your application starts showing growth.

4. Multiple V-condition:

Use the < div > to wrap the elements and < template > to wrap the extra element. It is advisable to avoid using various v- conditions to avoid multiple elements from the Vue component's render function.

5. Third-party packages:

The numbers of installed packages become so high whenever a team of developers is working on the same project that no one cares to pay attention to it and that indirectly affects the performance of the application and so for improving the performance, you have to import cost packages to look at the imported modular library and identify what's wrong when it is growing.

6. Stay consistent - Directive Shorthand:

@ for v-on

for v-bind

# for v-slot

You should remain careful while using these considerations, either to use them from the start or not use them.

7. Code splitting

Once the application is getting large, it becomes more than essential to make the performance fast and efficient as much as possible.

8. Routing

It is common to use client-side routing when you are building SPAs. Vue has an official plugin called VueRouter, and so there is no need for built-in routing; it is very much easy to work with and provides all the functionalities that you need to build a robust application.

9. Avoid accessing DOM directly

You should avoid accessing the DOM directly whenever you are programming on a Vue application; you will find it easy to access the DOM, and also, you will get to know that it is so much more maintainable.

10. Validate your props

You can easily forget the type, format, and conventions you have used in a prop whenever working on a large-scale project. So you must write prop validation.

Conclusion

To conclude, the above listed are Vue best practices of 2021 that you should consider because they will help you create the best Vuejs applications.
