Clean Up Code
A clean code is the backbone of every user friendly and efficient website you see out there. When you are developing a website or any application for that matter, it’s very important to ensure that the code you are working upon is clean and crisp.
HTML, or hypertext markup language allows you to format webpages with some useful text-organizing features like headings and paragraphs and you can also adorn your website with some attractive graphics with the help of HTML5.
HTML code should be both concise and effective apart from following all best practices when it comes to referencing other resources within your HTML document.
Apart from HTML, another important language of the web is Cascading Style Sheet (CSS). One important tip to keep in mind is to preferably put CSS components at the top of your HTML document's header in order to ensure progressive rendering. If it doesn’t necessarily improve the loading speed of your website, it will definitely prevent a blank screen from appearing or an unwanted flash of un- styled text.
In case of slow network speed, visitors are more likely to wait is most of the webpage's visual elements are already loaded. Hence, your website is said to be optimized and will boast efficient performance.
External HTTP Requests
We are talking about performance optimisation in web development and a majority of performance optimisation comes from a website's load time. Therefore, when talking about performance optimisation in web development, it is necessary to keep a check on the website’s load time.
Prefetching is an important term in web development. There are mainly three type of prefetching, that is, Link Prefetching, DNS Prefetching and Prerendering
CDN and Caching
CDN is an abbreviation for content delivery network, it can be used to improve the speed and performance of your website. CDN is the process where the website’s static content is linked to an extended network of servers across the globe. CDN becomes very important if the website caters to a global audience as CDN allows the website's visitors to load data from their nearest server and the website's files are automatically be compressed for rapid delivery across the globe.
A CDN is basically a method of caching that greatly improves the website performance. Nonetheless, there are other caching techniques also that can help the performance of your website. Browser caching is very important as it allows the browser to store certain files within its own cache so that the delivery is fast.
Compressing your files
In the previous point, we discussed about Content Delivery Network. If you use the CDN, another advantage is that it will compress your files. However, you can’t compress your files if you don’t use CDN by using a file compression method on your origin server. File compression greatly improves frontend optimization as it makes your website's content light and easy to manage. There are many methods used for compressing files like Gzip, Brotli and others.
These file compression methods are best for shrinking documents, audio files, PNG images, and other bulky files that need to be compressed in order to optimize websites. There are a couple of other methods and algorithms that can be used to compress file and other documents on your website.
File compression is one of the easiest and most impactful method to improve and optimise the website performance. Make sure the contents of your website are well compressed in order to provide the best experience to your users.
Using a Minimalistic Framework
If you are building professional websites, it is best to use a good framework that suits your project. There are many frameworks out there but some of them may contain a bunch of additional features and options that your web project may not require. Hence, it’s important to invest time and choose the best framework for your project.
In order to choose the best framework, you have to determine the important features of your project and then choose the perfect light weight framework for your project. Some examples of minimalist frameworks providing fast loading times are Pure, Skeleton including others.
Also, remember that a framework is not a way to escape careful web design, coding or programming and maintenance. A framework is like a new house which is clean and presentable, but empty. When you add features and customisations, it is your responsibility to ensure that the website doesn’t end up becoming cluttered and is not ruined by redundant codes, large images, and excessive unnecessary HTTP requests.
Eliminate unnecessary plugins.
Too many plugins on the website can unnecessarily slow down webpages and the website. Outdated plugins on your website pose security threats and compatibility issues that will majorly hamper performance. You should minimize the number of plugins you use on your Website by simply disabling and deleting any plugins that you don't use.
You should review the plugins first that you have installed in order to evaluate how many are necessary and how many are not. When you review some plugins, you realize that some tools are no longer relevant in respect to your website.
The most important thing is to identify plugins that reduce the page speed by first deactivating all plugins and then testing all plugins separately by turning them back, one by one.
