Component-based architecture is a way of building software with independent, modular, and reusable pieces—the components. Low-code platforms allow developers to build high-quality app components (also known as modules and patterns) and share them with others, boosting application development time and reducing code fragmentation.
There was a time when a component-based architecture was a novelty, but now Gartner includes components in the list of criteria for qualifying for their 2019 Magic Quadrant for Multiexperience Development Platforms.
What is a Component?
"Instead of building every application from scratch and requiring a whole team of experts and developers to work together synchronously, the work can be divided into smaller pieces."
A component is a reusable object that speeds up application creation and delivery and provides additional features. It turns code for common use cases, such as accessing a device’s GPS or calling an employee directory, into a module. Developers can easily add this module to applications so they don’t have to repeat themselves. They don’t need to write custom code for a common feature or capability that numerous applications require, which significantly reduces time and effort.
Components are multifaceted. They can serve as infrastructure pieces for your factory, added to more than one application. They can also live in a public component repository so multiple apps and developers can use them. Publishing them to a repository helps a number of people in numerous scenarios.
Advantages of a Component-based Architecture
Because of their structure and what they do, components have a number of advantages that are strengthened by a component-based architecture. Here are my three favorite benefits.
1. More Control and Lower Maintenance Costs
Say goodbye to searching for other applications where similar code might be used. Components enable the centralization of specific pieces of code. Because code is in one place, developers have more control over it. And, every time there’s an update or a fix, every implementation of their code will be updated and bug-free without the extra effort that can haunt their dreams.
Now, imagine an architecture based on components. You, your team, or your teams only have to debug, update, or perform tests in one implementation, considerably lowering the maintenance cost of your factory. Dependencies are no longer a nightmare; instead, they are part of a manageable process.
2. Faster Development to Save Time and Increase Revenue
Because of the reusability aspect, a component-based architecture reduces the number of developers needed to quickly create amazing apps. Logic components are context-free and front-end components already have great UX and UI. Therefore, developers can focus on implementing (only) the glue between them, in accordance with the application’s business rules.
Not only that, but system attributes such as security, reliability, performance, maintainability, scalability and usability (known as non-functional requirements or NFRs) are also guaranteed. As a result, your developers only have to consider them once. Afterwards, your developers can rest easy, knowing that things like performance, scalability, and security are already taken care of.
3. Take Advantage of Specialized Skills
With this model, developers can visit other developer communities and search their repositories for the component that suits their scenarios the best!
Write Less Code, Create Better Apps
Component-based architecture allows for easier, faster, and robust development. Companies with libraries of solid and ready-to-reuse components are able to shorten the duration of projects. By using well-thought-out components and a low code platforms, you can ensure that a successful project sees the light of day a lot faster!
Using a component-based architecture not only shortens production and delivery time, but it also frees up the resources required to ensure a quality delivery. For example, there is more time for code review and testing.
Remember that the easier it is to use your component, the less code you need! And the less code you need, the easier it is to create and publish.
