4 Simple Tips to Building Dynamic Lightning Web Components (LWC) in 2025

Lightning Web Components (LWC) are the future of SalesforceUI. They help developers build fast, modern, and interactive user experiences.However, using them right is equally important to ensure the right results are driven for the clients and products.

We’ve put together 4 simple tips for all Salesforce developers to build smarter and more dynamic LWCs in 2025 and beyond.

1. Break Big Tasks into Smaller Components

Our developers look at components like lego blocks. Similar to how making a huge structure requires small components to be pieced together, we suggest developers to approach big chunk of code by splitting into smaller pieces so that each has its own importance. For example, if you’re creating a form, make one component for the input fields, one for the submit button, and one for the success message.

We’ve seen that increasingly putting this into practice helps a lot because smaller components are easier to test, reuse, and fix later. Additionally, it keeps your code clean, avoids confusion, and makes updates easier.

2. Manage Data and Events the Smart Way

If there’s one thing that baffles our developers, it is passing data between components. In 2025, tools like api, wire, and message channels have been helping our team and alot of developers around the world make this activity smoother. We recommend using wire to get data from Salesforce and use events or message channels to talk between components.

Avoiding too much back-and-forth or hard-coded connections will ensure your app is flexible and easier to maintain when requirements change.

3. Make It Fast and Easy to Use

One simple yet important requirement that we get from our clients is to keep the app running at optimal speed and ensure its not slow. Our teams have gained expertise in using lazy loading (load components only when needed), avoiding heavy logic inside a single component, and using Java Script wisely to improve speed. In addition to these good practices, we also recommend developers to make sure their components work well on phones, tablets, and desktops by doing something as simple as testing with a keyboard too so that you can ensure your app becomes accessible to everyone.

For developers, the mantra is simple in 2025, which is faster apps make users happy while accessibility helps ensure we can make more inclusive products.

4. Test Your Work and Stay Updated

We are observing an increase in use of tools like Jest to write simple unit tests and catch problems early. Developers are also able to stay updated with new LWC features, which Salesforce keeps promoting as part of their improvements every year.

One of the biggest advantages for developers has been that testing saves time later, and learning new features helps them grow by staying abreast of upcoming trends.

In our experience, working closely with clients across industries, we observed time and again that building great Lightning WebComponents has everything to do with being smart, clean, and user-centric and very little about using fancy code that serves little to no purpose and complicated functionalities for end users.

We are confident that these 4 tips will help developers write better LWCs in 2025, whether they’re just starting out or already an expert, like our developers at Technolance who are just a click away. Talk to our Salesforce experts
