Optimizing the website plays a major role in accelerating the performance of a web application. You can also automate few tasks and use various technologies to speed up the performance of the application. In a survey, it was found that 47% of visitors expect a website to load in less than 2 seconds and 40% of visitors leave the website if the loading takes more than 3 seconds.
In this blog, we are going to discuss some effective ways that will improve your web application performance.
1. Reduce Application Size With Webpack
To resolve this issue coders started using helper code polyfills that ensured that the browser understood the code correctly.
A static module bundler webpack is also being used to resolve this issue. Webpack creates the dependency graph using the existing module. Webpack explores the packages and creates a new package with a minimum number of files that are required to run the application.
2. Use Cache in The Browser
The reason behind using a cache is the repeated use of scripts to access a specific object in your application. Performance immediately gets increased when you store the repeated object inside a user-defined variable as well as a subsequent reference to that object.
Your web application will load faster and the user will have a better experience. Remove the unnecessary libraries or dependencies from your code that don’t serve any purpose.
5. Use Minification
A lot of minification tools are available to minify your file or to unminify your file. Doing this will load your web application faster and users will have a better experience.
6. Use Gzip Compression
7. Avoid Unnecessary Access to DOM
Keep in mind that if you remove the value of the DOM then set the variable to NULL to avoid the memory leak in your application.
These were some useful techniques to boost the performance of the website. Although these are good techniques still you should follow some best practices to boost the performance. Avoid unnecessary nested loops and recursive calls. Use search array instead of using a switch case statement. Use bit-level operators in your code to take the advantage of fewer processor cycles. Also, avoid using global variables and consuming too much memory.
