The most well-liked and reliable JavaScript framework for website development is VueJS. However, if you ignore it, performance will suffer like other frameworks.
You have chosen the right site for your large-scale application, whether you're looking for tried-and-true Vue js performance optimization methods or want to learn about vue best practices. Let's get into the specifics of Vuejs app performance. Optimize without further ado.
Why is Vuejs performance improvement necessary?
No programmer will ever wish that even after writing thousands of lines of code, customers don't want to use the application because it takes too long to complete user operations.
Product developers worldwide create goods for consumers, and these users primarily focus on having seamless experiences. If end users are not pleased with the performance, speed, and efficiency of Vue JS, it does not matter how much effort programmers put into the architecture of Vue JS apps.
So, sure, that is why it becomes a requirement for Vue optimization to get higher performance that will ultimately satiate the end user's wants.
Major Factors Contributing to Poor Vue Performance
Let's examine the functionality of Vue js and the leading causes of underwhelming performance.
- Using third-party libraries carelessly
- Forgetting to use lazy loading and code splitting.
- Queries for APIs receive unwanted hits.
- JS and CSS files are not being correctly organized.
How can the Vuejs app performance be improved?
You can improve your Vue JS app performance by using the following performance recommendations.
1. Vue JS's lazy loading
According to its name, Vue js's Lazy Loading feature allows you to load modules into your application only when the user needs them. When users visit the website, it's undue to pack every module from the JavaScript bundle.
When required, tooltips and modals can be loaded for some components. You won't notice the effect if you only have two or three models or tooltips. However, if you have many modals and tooltips in your Vue app, loading them all at once may affect how quickly it loads.
It would be best if you did not load the complete bundle every time the page loads. Therefore, loading makes it easier to divide the fortune and load them when needed. By avoiding downloading and interpreting the pointless code, time is saved.
2. Using Routes to break up the code
Consider that you must create a simple VueJS website with Dashboard and Contact pages. Vue-router must be used in your project, even for these two pages. This standard coding practice ensures that the Dashboard and Contact components are downloaded even when the user navigates to another page.
Neither Contact nor Dashboard is something we wish to download. Since both routes are in the same bundle, this is the case; what's so crucial about downloading two additional pages? But when working with large apps and large fortunes, this matters.
3. Vue js prepare the elements
Let's continue and go deeper into Vue JS. For instance, you might consider prefetching the product page if you know that most people will travel from the category page to the product page.
It would be beneficial if you were to remember that prefetching can only occur after the initial render. Prefetching has the additional advantage of eliminating the harmful effects of lazy loading without sacrificing performance.
4. Enhance the Third Party Library
When you check your bundle size and are startled if it exceeds the desired level, the culprit is frequently the use of loaded third-party libraries rather than your coding. Yes, all of us utilize third-party libraries without fully understanding how they affect the functionality of our applications. One or two bytes of the bundle size could be our code.
Bundlephobia can help you understand how various libraries can impact performance. You may learn a lot about your website data by adding the Vuejs library name to this beautiful website.
5. Utilizing browser caching
The topic of bundle size has been sufficiently covered; in this final step, we will concentrate on caching the data. Caching is a method of keeping only a portion of data so that it can be quickly accessed when needed.
Up until the browser is not closed, the data in the RAM cache is kept. You may verify this on your own.
Select the Network tab in your developer tool after opening it. Reload the page on any website several times. As illustrated here, some static files will have a RAM cache. This indicates that the memory cache is being used to serve these files.
Conclusion
Any program you create needs to be optimized at some point, no matter how big it is. You are only a click away if you're looking to hire a VueJS developer to optimize your Vuejs app performance for your end customers.
