Boost Your Web App’s Performance 3X with ReactJS Migration Services

To stay competitive, organizations need to embrace the latest technology stack development services. Having well-designed and high-performing websites and applications is the demand of today’s competitive business world. Customers often seek websites with high performance and easy usability. And therefore, you must use the best framework to build an appealing and high-performing user interface design to keep your customers staying longer on your site. React is one of the most widely used JavaScript-based frontend development frameworks by enterprises, according to recent statistics. Therefore, many organizations are turning to ReactJS migration services.

One of the significant features of the React frontend development framework is that it helps developers to build large and complex web applications without page reloading. The framework is simple, user-friendly, offers high performance, and supports one-way data binding. Migrating a high-traffic and extensive web app to the latest technology is not an easy walk on the path.

So, what’s the process of migrating to React? As an experienced ReactJS development company, we are going to discuss the process of React migration and the major benefits associated with it.

But first, let’s understand why companies choose React over other JavaScript frameworks.

Why Do Companies Prefer to Use React?

There are various reasons for migrating from the existing framework to React. Here are some common reasons why companies prefer to use the React framework.

  • The current application does not perform appropriately according to the latest updates, UI developments, browser features, etc.
  • No built-in support for SASS
  • Higher subscription fees, and costly cloud services
  • The architecture of the web application is not scalable
  • Lower user engagement rate
  • If you are also facing the above-mentioned issues, we advise you to hire ReactJS developers for building a web application that has high performance and is easy to use.

    Step-by-Step React Migration Process

    If you have decided to migrate from your current framework to React technology, having low a budget might be one of your biggest concerns. By following our React migration approach, you not only save cost but also save your valuable time and resources.

    The React migration process is broadly divided into four essential stages. We have described each stage to help you avoid any mistakes during the process.

    STEP 1 – React Migration Planning and Preparation

    As said earlier, migration from any framework to the React framework is not an easy task. You need to manage and maintain your application’s traffic and data throughout the process.

    In this stage,

  • You must identify all business-critical risks, migrations aspects, and negative impacts on your app’s visibility in the search results.
  • Make sure to take necessary measures and predict migration situations to obtain feasible opportunities.
  • Obtain feedback and suggestions from your stakeholders and employees on your web content, UI/UX, app analytics, and SERP from the previous stages.
  • Focus on making your web application more secure by building a robust architecture.
  • Find issues exiting within the new app template and fix them.
  • Remember to remove large chunks of irrelevant plugins, APIs, and categories.
  • STEP 2 – Test and Analyze Your Web App before Migration

    Testing and analyzing the whole web application is a crucial step that you need to perform before the React migration. The pre-migration analysis helps you identify what’s necessary to be migrated and what you can ignore. Search Console remains on a server for about 9 days, however, it might still be useful to pull the traffic for the new web app. So, don’t forget to create a backup of your Search Console data.

    What you need to focus on:

  • Separate the Document Object Model (DOM) and the state transition between your current tech and React.
  • Use JAMstack to convert your existing code base to ReactJS to get it rendered at build time.
  • Leverage the element renderToStaticMarkup to retrieve data from the old APIs.
  • Include the state function of React into components that you need to separate and ten migrate essential dependencies.
  • Besides, below is a list of things you need to export from your existing web application to the new one.

  • Resources that have been blocked from the repository of old web app
  • Desktop, mobile, and tablet usability problems
  • Caches, URL parameters, and plugins
  • Crawl error backup
  • Internal as well as backlinks to the web app
  • Page indexing data status
  • Data structure errors
  • Copy all pages’ metadata
  • A few more crucial test parameters to monitor:

  • Important additional test parameters to keep an eye on
  • The search engine must not crawl to your staging web application that is going to be migrated.
  • Prevent access to all IPs excluding the essential, whitelisted ones.
  • Preview the user journey in the existing app and create a backup even if it’s only a heat map. This will help in enhancing the user journey and experience after the migration.
  • Analyze the web app architecture frequently to create potential organic traffic.
  • STEP 3 – Deployment Support Post Migration

    After the React migration, another important step is web app deployment. To save the extra bytes with high performance, you can use elements like ReactDOM.hydrate() on the client-side and renderToString on the server-side.

    This will generate a low-sized HTML by quickly marking down all earlier server requests. ReactDOM.hydrate() makes the React migration much easier. You can create a first-load and faster performance of your app.

    Important keynotes to consider:

    Make sure the downtime of the old web applications is the minimum.

    When downtime occurs, see that the old application returns a search call with a 503 error server response. This will help the search engine crawlers missed during the downtime to return and you can retain the search data and traffic.

    Now here’s what you can do to provide strong support to your web application:

  • Redirect top-performing pages to your new app manually
  • Check all your canonical tags
  • Check the server response with all web pages
  • Make sure all XML sitemaps are uploaded and thoroughly tested
  • Remove duplicate content by configuring URL parameters
  • STEP 4 – Review Performance Post React Migration

    At this stage, you get access to robust tools, plugins, data, and features. Any complications in this phase, however, may hurt your web app’s performance and search engine ranking.

    Most errors detected in this stage, e.g. a bug in the setState function, will be identified automatically by the latest version of React.

    Here are some of the things you need to check:

  • Crawler stats
  • Server logs
  • Crawl errors
  • Statistics of both versions
  • You may use Google Analytics to identify all the 404 broken URLs and fix them first. Finally, make sure to redirect URL images from our previous web app to the new one. Even Google suggests doing this to maintain your SEO ranking after the React migration.

    Focus on the following performance analytics:

  • Online visibility metrics
  • Search engine ranking across all platforms
  • Page loading times of both versions
  • Performance of all pages across various devices
  • By following this checklist, it will be easier for you to migrate from the old technology to React. If you’re a newbie, you may approach a professional ReactJS development company for smooth and hassle-free migration.

    How to Move Your Old Technology to React

    First, create JavaScript and import all contemporary tech dependencies into the new JavaScript. Several dependencies will globally register themselves in your web app objects. However, you might detect that certain dependencies need to be migrated manually. You can leverage packages such as react-dom and react-more-react to carry out precise rendering and intelligent text truncation.

  • Make use of Rollup, the module bundler of React, to import and export essential library modules during the migration process to build a robust repository infrastructure.
  • Send data across different layers using CSS classes like ngClass, ngif, ng Show, or ngHide and ng switch to swap crucial directives with React. You can use this approach when migrating from Angular to React.
  • Build a bundle of dependencies that need to be migrated and index them as per your requirements.
  • Render React components into all the dependencies that are involved in your new web app created for migration.
  • This technique will give you a middle ground to distribute dependencies and developer tools across the contemporary technology to React, saving you a lot of time and resources.
