Let’s talk about the risks in more detail:
The framework is found unacceptable, and you will have to rewrite your app fully to eliminate the technical gap.
To avoid it, ensure the chosen framework is modern and future-proof. The IT world is constantly changing, and so are development frameworks. They tend to change every 5-6 years, and the differences may have little to nothing in common. Thus, changing a framework might often require a complete rewrite of your project. Sad, but true. If there is a smooth transition from one framework to another, you are a lucky person. When choosing a framework, check how long it has already been on the market and try to predict how long it may be valid. If a newer framework is on the horizon that has the potential to outperform the chosen one in the coming years, it is worth considering the newer one.
Your team may not know how to use the chosen framework across all departments.
To avoid this risk, evaluate the expertise of your current development team. Check how the framework’s tech stack aligns with your vision of your development team’s skill set. We have seen many clients who got so inspired and excited by a new dazzling framework that they wanted to introduce it into their product immediately. But the problem was that almost no one outside of their R&D team knew how to test or support it in production. To estimate the cost of the new tool from the earliest adoption stage, you need to take into consideration all departments. They include delivery and maintenance teams, developers, QAs, DevOps, production and site reliability engineers, and even a database department.
If you already have a legacy framework and introduce a new one, you might need to hire more developers if the tech stack is different.
We have seen clients with two frameworks that are incompatible within various departments. And thus, the specialists within the company weren't interchangeable. So, if there was a need, they couldn't be switched between the projects. Moreover, the company faced hiring difficulties. They needed to hire two specialists with distinct skill sets, such as .NET + NodeJS, PHP +.NET, or Java + NodeJS, which a single developer rarely possesses.
To avoid any of these risks, it is best to have a tooling strategy in your company and settle on one tech stack. Or to have a transition and resource plan in place to migrate from multiple stacks to a single stack.
To sum up, you will consider a list of options while selecting the best front-end framework for your application. You should understand why it is crucial for your project to opt for this particular front-end framework. To make the right decision, you need to rely on your business specifics, goals, and objectives.
