How Software Development Benefits From MVVM (Model–View–Viewmodel)

How do the best software development teams create the best apps?

Modern mobile and web application developers use a structured method to manage their projects. Organizing code into logical design patterns produces quality apps that are easy to maintain. Future updates require less time which means less expense for the business app owner.

One design framework that stands out from the others is MVVM or Model-View-ViewModel.

The MVVM pattern overcomes the problems of older methods. It does this by separating data presentation from business logic.

But what does that mean and how can it lead to building better apps?

Read on to discover how MVVM architecture is revolutionizing the software development landscape. Learn about the pattern’s benefits and how it can help businesses through boosted performance and easier edits.

App Design Patterns

Consider a large web or mobile application.

The user sees a series of screens that they can interact with like swiping and tapping. When they press a button, something happens behind the scenes to process that tap.

Rules called business logic check to see what the user wants and if they’re allowed to do it. That result gets returned to the screen to play a video, for example, or present a warning message.

Separating these elements is crucial to the best business app designs.

Why? Because it allows several team members to work on the same project at the same time. It also means they can update one page of code without having to rewrite the entire app.

There are several design patterns or software models that help achieve this, the most common being MVVM.

What Is Model–View–Viewmodel Software Development?

Model-View-ViewModel or MVVM separates program logic from the user interface (UI) controls.

Microsoft architects created MVVM in 2005 to simplify UI events. Instead of using huge pages of code that were difficult to maintain, they broke them into modules that linked with each other.

The result is faster development and reusing code is simple and quick.

MVVM Architecture

MVVM is divided into three core elements:

  1. View
  2. ViewModel
  3. Model

The View includes user interfaces like interactive elements, text, and animations.

In MVVM, the View is not interacted with directly. Instead, a different element changes what is presented on the screen — the ViewModel.

The ViewModel sits between the Model and View layers. It’s responsible for communication between them and notifies the View of any changes in state.

In other words, the ViewModel tells the View how to function but the View decides how to display that to the user.

The Model acts as the brain behind the app, holding all of the main logic. It decides what information gets passed to the ViewModel which in turn gets displayed to the user.

An example of MVVM in action would be when a user performs a search.

The View sends the query to the ViewModel which then speaks to the Model. The Model returns a set of results to the ViewModel which then binds to the View to display them.

Data Binding

The major difference between MVVM architecture and other design patterns is data binding.

Data binding links a View with the ViewModel. This automated, two-way connection ensures instant updates to the UI when something changes.

These binders join the three core elements together to ensure a smooth user experience.

In Android Development, the DataBinding library manages this with ease. It reduces the amount of code by using data expressions directly within the layout.

This speeds up development and makes coding edits easier in the future.

MVVM vs MVC

MVC or Model-View-Controller was a common architecture pattern used to develop apps before MVVM.

MVC also separates the user interface from business logic but it leads to lots of unnecessary code. Over time, this becomes unreadable and very difficult to maintain.

MVVM is now the industry standard because it offers a range of benefits over MVC.

Benefits of MVVM Architectural Pattern

The software development teams at Tartlabs use the Model-View-ViewModel pattern when building apps. Read on to discover why.

1. Maintainable Code

The unique way MVVM separates the elements of the app results in more maintainable code.

Instead of lumping everything together, the MVVM pattern makes code cleaner by placing it in different files. Programmers can then identify blocks of code which makes future edits less cumbersome.

2. Modular Testing

Module testing checks blocks of code in a program without having to test the entire app.

The practice is recommended because:

  • It has a higher probability of catching errors or bugs
  • Several modules get tested simultaneously
  • The complexity of testing is easily managed

Finding and eliminating bugs is essential to a great app and MVVM delivers with this practice.

3. Easy UI Edits

Some developers don’t consider future edits, especially when it comes to the user interface. They include unnecessary code on the UI screen which makes it difficult to change at a later stage.

The MVVM architectural pattern removes non-essential information making edits easy.

4. Boosted Performance

MVVM is designed to improve performance.

Data binding produces a streamlined system to send and receive data within an app. Even with three elements controlling logic and the UI, binding ensures everything works smoothly.

5. Better Collaboration

MVVM improves app development as team members can work on multiple files at the same time.

The separation of codebases allows for better collaboration which speeds up development. It also allows for remote developers to work on a project simultaneously.

MVVM Pattern Software Development With Tartlabs

The MVVM architectural pattern makes the app building process more streamlined.

By separating UI from core business logic, the MVVM pattern leads to maintainable code. App owners won’t receive huge bills as developers can work on projects in a fraction of the time. And the apps are more secure and grounded due to modular testing.

Tartlabs promotes the use of MVVM when developing iOS, Android, Hybrid, and web apps.

Our software development teams take advantage of MVVM to prototype and design applications. We’re fully versed in React, Angular, and backend coding along with Firebase, Alexa, and e-commerce sites.
