When Should you Opt for Web App Frontend Refactoring?
Get to know the top possibilities when your web app might suffer from performance pressure and give in to it.
Frontend Modernization with the Evolving Technologies
Remember the times when we had 2X retina images? Well, new Internet users wouldn’t remember these. And, the moment they land up on your page, they are sure to bounce back to the ones with the better pixels.
It’s not only about images to display but also about programming languages used for the frontend development of your application. With every new feature in your application, the size of your code swells up and it could pile up into a code smell, creating code complexity for you. Hence, while you are at embracing new technology, also take a moment to look back at your code for application modernization.
Prepare for Web App Frontend Modernization with the Increase in Traffic and Visitors
Of course, you are in for the long-term with your web application! And, you might also stand by the wishing pool to turn your high-traffic mobile or web application resistant to sudden or gradual spikes in terms of usage. While there are many other important objectives to achieve with application modernization, you do not wish your users to encounter an error 404 because your web app can’t handle a lot of traffic.
When your web app begins to show performance issues with increasing traffic, it’s time to hire frontend developers for frontend refactoring.
Prioritize Changes in Frontend of Web App for Aesthetics of your App
With thousands of web apps and more coming up to compete with your app, the surefire way to win the ‘web app wars’ is through the UI. However, in a world where even fashion trends are ever-changing, you can’t go on for years with the frontend you first developed during the launch of your web app.
Not me, but web apps with excellent user experience says that they keep evolving with the latest design trends to keep their users interested and craving for the next ‘new’. Hence, if you see some visitors drop on your analytics dashboard, it’s the right time to hire a frontend engineer for application refactoring.
Web App Frontend Modification for the Addition of New Features
Stay agile to stay at the forefront!
The agile web app development approach is as much backward as forward it is! Hence, when you are planning to fill your user’s engagement level to the brim with the addition of a new set of features, don’t forget your existing codebase.
When you opt for agile methodology, you will stay responsive to modifications; not only of the new but also of the old. Since adding new functionalities would translate into a bigger code size, you can hire frontend programmers to understand the structure of your application and make it scalable and simple for the sustainability of your business.
Refactoring for Improving your Legacy Frontend Architecture
When the code keeps piling up, it might cause performance issues. Add to that the pool of redundant code and unexplainable implementation of features, which further degrades the performance of your web app.
When you encounter a performance issue, your code may no longer be legible. It might lack an evident page entry function with unreasonable design and might confuse your users about the next actions on the web app, thereby increasing your bounce rate. In such a situation, you can hire a frontend developer for your refactoring needs or you can ask your in-house developers to do so.
Web App Frontend Revamp to Resolve Overcomplicated Frontend Scripts
There could be multiple notions projecting the code smell. In such a case, the code might get over complicated with multiple layers, codes, variables, classes, parameters, loops, conditions, and more. When you superimpose some of your functionalities above this code, it might not perform as expected and show bugs. As a result, the testing and detection could consume a lot of your web app development time.
The best solution for you is to ensure that your code is clean and easy to understand. Before adding anything new to the code, you can remove this overcomplication so you know the architecture thoroughly and even expect better outcomes from its performance.
Frontend Modernization of Web App to Curb Complications with CSS
As much as CSS can help make the website, it can also cripple the development of the frontend. If you are constantly using CSS and modernizing your web app, it might show cosmetic problems in the long term.
Manipulation in CSS can occur, owing to equal-height columns or vertical centering, which can break the build. In addition to this, it also shows architectural issues, which can be conflicting with multiple other rules on the page.
If you need to get away with CSS issues, one of the best ways is to use the proper Block-Element-Modifier conventions. In case, if you feel that adhering to BEM conventions is not practical, you can use third-party plugins for generating a part of HTML.
Frontend Application Modernization for Function Iteration
When you are adding a new function to your application, you might see that the original design can’t match the new requirements. If you even attempt to begin with the addition of the feature on the application, it might only lead to complexity and unnecessary layers.
If you are adding new features and want to have absolutely no implications on your frontend design, you can opt for the reconstruction of your app. You can secure interfaces for any kind of requirements in the future and have a clean layout for the frontend of your application.
Frontend Revamp for Detecting Bugs and Errors Users Face
Your app needs continuous testing to offer a reliable and error-free user experience. In such a case, if you are thinking about bringing advancements to your application or have recently launched your application in the market, you should prepare your app for any critical changes.
In order to be in the long-term race with your competitors and your application, you have to check out feedbacks from users and keep on improving it. If your users are facing errors with your application, you can take the opportunity to revamp your business logic by opting for frontend refactoring.
How to Approach Web App Frontend Refactoring?
Staying true to your methods is one of the best ways to approach refactoring. In this section, we will help you understand the underlying process with utmost simplicity yet details:
Split your Code into Smaller Components:
The first step is to split the frontend and backend segments into different entities. You can establish communication with the help of REST APIs. As a result, you can carry out the distribution of the necessary workload to page servicing. In addition to this, it can, in turn, facilitate issue sorting arising among various F/E as well as B/E departments. As a result, it can enable departments to work on the code in parallel.
In addition to this, splitting code into components can help you focus on specific functionality–display the main menu, display the image gallery, and display the main content. Besides this, the complexity of each of these components can be verified.
Focus on the Crucial and Mandatory Files First:
When the browser receives these files, it will begin the rendering process without looking for other files from the page to load.
Take a Mobile-first Approach:
Since smartphones are better accessible than their bigger counterparts–PC, laptop, and tablet, it is essential that while you have initiated the web app frontend refactoring process, you also focus on the responsiveness.
By responsiveness, we don’t only mean your web app’s compatibility with other devices and browsers; but with mobile phones specifically. If your old frontend layout is not well-optimized for smartphones, you might have to face a high bounce rate. Hence, it is essential to take a mobile-first approach to accommodate a high number of mobile visitors for your web application.
Under the reflowing approach, you can focus on three aspects for carrying out better frontend refactoring.
You can begin the process by porting the old frontend layout when you start a project. For further simplicity, it is recommended that you keep the names of variables and multiple events unchanged. However, you need to transcribe the old and asynchronous actions to pure functions.
The second step is to redesign the key pages of the web application. You can execute this step one page at a time, based on the usability and compatibility with the old flow.
The next and final step is to design and enrich the remaining pages with features and make these pages sustainable for future utilization.
In this step, you need to load a script. However, at the same time, you need to ensure that the key thread remains unblocked and mention it as asynchronous. When you have to include it as HTML page, you can use the async attribute.
When you have set the scripts as async, it will tell your browser about the non-blocking scripts. As a result, your browser would not have to wait for these scripts and it can move ahead.
In addition to this, the script is anticipated to begin running as quickly as it is received. The script would not even have to wait for any kind of notion of order.
Code Coverage of CI/CD:
The code coverage can be used to determine the degree of source code when it is run on a specific test suite. There are multiple metrics used for the calculation of test coverage.
It is crucial to write the test suites for achieving about 90% of code coverage. It is critical to achieve this rate for the preservation of the business logic and to avoid having redundant code for particular expected business behaviour. When you integrate test execution in CI/CD process, you can rest assured about the solidity of your frequency releases.
Further Improvements for Web App Frontend Refactoring
When you want to have a better score with your web app frontend refactoring, you can further practice the following ways:
Opt for the mobile styles when you are accessing the browser on mobile devices.
Similarly, use the desktop styles for desktop devices only.
Keep the global file in a global small file. It should not be duplicated in critical-CSS components.
In the end, all we need and desire are happy end-users. So, if you don’t see any drastic improvements in your app even after the web app frontend refactoring process, come to our experts and get your issue resolved.
