What Are Dependencies of a Mobile App?

Tyler Yates

In today’s digital era, mobile applications have become an integral part of our lives. We use them for everything from ordering food to booking a cab.

However, have you ever wondered what goes behind building a mobile app? One of the critical components of any mobile app is its dependencies.

What are Dependencies?

Dependencies refer to the external code libraries and frameworks that a mobile app needs to function correctly. In simpler terms, it’s like building blocks that developers use to create a robust and efficient app. These dependencies help in reducing development time, improving the overall performance, and adding new features without reinventing the wheel.

Types of Dependencies

There are two types of dependencies that mobile apps rely on:

1. Internal Dependencies:
Internal dependencies are the code modules within an application that interact with each other to perform specific functions. For instance, if you’re building a banking app, you’ll need modules for logging in, checking balance, transferring funds, etc.

2. External Dependencies:
External dependencies are third-party libraries or frameworks that developers integrate into their apps’ codebase to improve functionality or user experience. These can be anything from UI/UX design tools to payment gateways or social media APIs.

Why Are Dependencies Important?

Dependencies play a significant role in simplifying the app development process and making it more efficient. By using existing libraries and frameworks, developers can reduce development time considerably while still maintaining high-quality standards.

Moreover, using dependencies also helps in keeping up with industry standards and best practices. With new technologies emerging every day, it’s impossible for developers to keep up with all of them while also building an app from scratch. Dependencies help bridge this gap by providing access to cutting-edge tools and features without requiring extensive knowledge of these technologies.

The Risks Associated with Dependencies

While dependencies offer several benefits, they also come with their share of risks. One of the primary concerns is security.

If a dependency has vulnerabilities, it can pose a significant threat to the app’s security and user data. Developers need to keep track of all the dependencies they use and ensure that they are regularly updated to avoid any potential security breaches.

Another risk associated with dependencies is compatibility issues. Different libraries and frameworks have different requirements, and if they aren’t compatible with each other, it can lead to bugs or even app crashes.


In conclusion, dependencies play a critical role in mobile app development. They help in reducing development time, improving performance, and adding new features without reinventing the wheel.

However, developers need to be mindful of the potential risks associated with using third-party libraries and frameworks. With proper management and regular updates, dependencies can help build robust and efficient mobile apps that meet industry standards while providing exceptional user experience.
