Trailblazing Success with ASP.NET Core: Built a Custom Web API

“APIs streamline and simplify programming with a standardized way of communication.”

In this tech study, we will walk you through our journey to build Web API with ASP .NET Core 7.0 to offer CRUD operations for our client’s web app. One of our previous clients operating in the travel business approached us with a web application project. The client wanted us to create a custom API to manage data related to users.

Our client offers a wide range of tour packages to international locations, and they have a diverse customer base. In addition, they offer services like outdoor recreation, help customers find the best travel deals, and offer bookings and reservations. So, choosing the right technology was essential to provide the client with an efficient and reliable web solution to handle a vast user base.

As a trusted web development partner, we analyzed their requirements thoroughly and considered different aspects like source of data, users, IT infrastructure, and more to make our decision. We found that ASP .NET Core was more suitable for their project, and it also supports creating Web APIs.

Keep on reading to learn how we used ASP .NET Core to build Web API; the challenges we faced along the way, and how we tackled them successfully.

Quick Facts: Among all the websites on the web, 6.8% are using ASP.NET Core besides other frameworks and technologies. Many popular companies are using the ASP .NET Core framework for their websites including Slack, MasterCard, SpaceX, ROBOLOX, and Alibaba Travels.

Power of ASP .NET Core Unleashed: What We Did to Meet Our Client’s Expectations?

Tour and travel applications are required to maintain a wide range of data from users in different locations. It demands efficient communication between the server and the client to retrieve and update data seamlessly. Our choice was ASP .NET Core, to meet this requirement because of its cross-platform nature to work with multiple environments. The choice was even more fruitful for the client’s on-premises and cloud-based data sources. ASP .NET Core is a high-performance and open-source web framework used to build minimal and controller-based web APIs.

What expectations did the client have from us?

• Build Web API for CRUD (Create, Read, Update, and Delete) operations to add new users, delete users’ data, update user data, and retrieve data.
• Clear and comprehensive documentation for the API to define its features and components.
• Create a complete backend for web application including database and server setup.

Managing complexity was one of our primary goals when creating the web API to make sure that the overall functionality was seamless. We followed REST (Representational State Transfer) architecture that reduces complexity in API development to create RESTful services.

Why Did We Opt for ASP .NET Core to Build Web API?

ASP.NET Core is perfect for creating HTTP services that are compatible with many platforms. So, a large number of users can access HTTP services from any web browser or device like mobile, PC, or tablet. It was the main reason we chose ASP .NET Core for our client’s API development project.

Since there was a diverse clientele that possessed a multitude of devices, we found no better option than ASP .NET Core to build API owing to its cross-platform compatibility. As we have sufficient experience and knowledge in custom web app development, we know how powerful ASP .NET Core is when it comes to API development.

ASP .NET Core is a flexible web framework that supports many types of programming styles and methodologies. The following are all the reasons why we chose ASP .NET Core to build a web API for our client.

Enhanced Security: ASP .NET Core offers built-in features that help in creating highly secure APIs. For example, it offers built-in JWT (JSON Web Tokens) that encodes JSON data to securely exchange between sender and receiver. JWT and other such features enable us to build secure API endpoints. ASP .NET Core also allows us to define strict access control roles with robust policy-based authorization.

Easy Serialization: There are lots of benefits to using ASP .NET Core to build modern web experiences and serialization is one of them. It provides serialization to JSON out of the box for different endpoints. So, regardless of which endpoint is used the data is automatically serialized to well formatted JSON without special configuration.

Testing with HTTPS: Today, your web application is secure when it uses HTTPS protocol. Applications are usually tested with HTTP protocol after development which may lack a clear picture of security. Luckily, ASP .NET Core is fully compatible with HTTPS protocol and allows testing applications on HTTPS. The testing certificate is generated automatically and imported to enable local HTTPS when the application is run. So, it is easy to run and debug apps to ensure high-end security.

Scalable and Fast: Speed and scalability are among the most essential factors when deciding the best web framework. ASP .NET Core is found to be the fastest among popular web frameworks as per the TechEmpower benchmark.

Flexible Deployment: It is possible to deploy applications built with ASP .NET Core on multiple environments like central web servers or the cloud. Hence, this web framework can be used to build applications for on-premises, cloud, or both.

Modular HTTP Request: ASP .NET Core provides multiple modules and handlers that process requests. A client’s requests pass through different modules like the authentication module and session module process before a single HTTP handler processes it.

Dependency Injection (DI): Another advantage of ASP.NET Core for web API development is built-in support for dependency injection. DI makes code less complex and ensures that classes and their dependencies are loosely coupled. Consequently, you can maintain, test, and reuse code easily.

Middleware: ASP .NET Core has unique features like the support of middleware. It is a component that helps to process requests and responses in a pipeline. Basically, it’s a class that is executed on every request. It is useful in handling requests and responses.

Our Challenges and Solutions: How We Achieved Excellence?

Our developers faced a few challenges during the development process and solved them with their professional knowledge and problem-solving skills. They found out the best way to solve every problem and built a robust API at the end. Let’s take a look at the challenges they faced.

Integration

There was a challenge to build the API to meet the requirements for different types of systems including legacy systems. Ensuring compatibility with multiple systems, especially those with legacy technologies, was not an easy feat. Our developers worked with optimal API architecture and design patterns to meet the client’s requirements.

Security

With hackers increasing their knowledge and attempting more intelligent attacks today, ensuring the best security features is not an option for web-based solutions. Our developers not just prudently utilized ASP .NET Core security features like proper access control, authentication, encryption, and more, but also focused on optimizing the API from at the code level to remove possible vulnerabilities.

Compliances

People are becoming more aware of personal data protection, and they demand control over the use of their data. As a result, there are many rules and regulations that companies which store and process personal data of online users need to comply with. So, it is important to build a web-based solution to meet the compliance requirements. Our developers built the Web API with ASP .NET Core adhering to industry standards and compliances.

Optimization

Our developers did all optimization work to improve API performance, efficiency, and functionality. They took multiple measures to optimize API performance with caching, filtering, pagination, and more. Complexity is reduced with clear and concise coding as well as proper commenting.

The Final Step: Measuring the Outcome

After the complete development of web API and integration with their backend systems, the client was delighted as it met all of their expectations. The API is working with their systems smoothly and users can easily write, edit, or remove data with the web application. We are happy that the performance of API is excellent, and it can handle multiple requests.

We worked with the right approach and helped our client build an efficient web API with the ASP .NET Core framework. The client was satisfied with our ASP.NET Core development services for developing custom web API and has shown interest in working with us on future projects too.
