Component Architecture: 3 Reasons to Invest
A component architecture is a type of application architecture composed of independent, modular, and reusable building blocks called components. When designing an app following component-based architecture principles, developers combine, reuse, and version these objects, rather than building every inch of an app from scratch.
Let’s be honest: in times of uncertainty where speed is paramount, meeting the increasing app demand while maintaining complex technology is a herculean task for any development team. The value proposition of a component-based architecture is that it boosts application development time and reduces code fragmentation.
But before diving into the reasons to invest in this type of application architecture, let’s start from the very beginning, because the sustainability of any component architecture lies in the quality of its components.
What Is a Component?
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, significantly reducing 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 several people in numerous scenarios.
Types of Components
Generally speaking, components can be dedicated to specific application layers, such as backends or user interfaces.
For different layers of an application, there are different types of components, including:
- Themes that define the look and feel of the application, through a series of style sheet rules, and the grid definitions used to position and size elements on the screen.
- Widgets or blocks that provide additional and reusable features, usually related to UI or events. To become components, blocks must include a set of definitions, such as parameters and variables.
- Connectors that allow integrations without the need to write custom code, significantly reducing time and effort and eliminating errors. Broadly speaking, connectors allow for integration with other applications, for example, Facebook or Paypal.
- Plugins are add-ons that are installed on a program, enhancing its capabilities.
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. 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, freeing your team to focus on more impactful business requirements. 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 and rest easy, knowing that things like performance, scalability, and security are already taken care of.
In addition to that, the ownership of a component is clear to everyone, since there’s always a DRI (directly responsible individual) responsible for maintaining and updating the components, thus processes of change management are much more streamlined and easy to carry out.
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!
More Apps, More Quality, Less Time
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 modern application 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, and the more time you have for innovation.
