Web Application Development

Every developer should understand the difference between an API (Application Programming Interface) and an SDK (Software Development Kit) in web application development technologies. Knowing when to provide each is essential for creating a developer ecosystem. Online communication and the installation of third-party APIs are driven by these two technologies and their synchronization in the current development landscape. Additionally, how do all Vietnam-based software outsourcing companies choose when to employ API and SDK.

1. What is Web Application?

A web application is computer software that executes a certain task using a web browser. Web apps are another name for it. There are web apps on a lot of websites.

A web application is a client-server program.It turns out that there are client and server sides to it. The program that a person uses to run the application is referred to as the “client” in this context. It is a component of the client-server environment, which allows numerous computers to share data. The client, for instance, is the application the user uses to enter data into a database. The software that stores the data is called a server.

2. Benefits of Web Applications

Numerous advantages of a web application include the following:

  •       It doesn’t take up any space on the hard drive because you don’t have to install it there.
  •       It has fewer technical requirements for the user’s computer and needs less care and upkeep from the company.
  •       A web application lowers costs for the client and the company.
  •       Because changes are applied centrally, web applications are always current.
  •       Since everyone can access the same version, all compatibility difficulties are resolved.
  •       With a web browser, you may access web apps from any location.
  •       Web apps can operate on several platforms, independent of the operating system or device, as long as the browser is suitable.
  •       Web applications absolve the developer of the burden of creating a client that works with a particular model of a machine or operating system.

In web apps that need a membership, web applications prevent software piracy.

3. Types of Web Applications

3.1 Single-Page Apps

Single-Page Application (SPA) is a program that runs within a browser and does not require page reloading during usage. SPAs often use an infinite scroll functionality to display all of their material and manage everything from a single page. SPAs can be seen in many of the everyday programs you use, like Facebook, Google Maps, Gmail, Twitter, Google Drive, and even GitHub.

Their quickness, simplicity, and ease of building and debugging web application development technologies while deploying are their key benefits.

3.2 Multi-Page Apps

A multi-Page Application (MPA) is a program that has numerous pages and reloads each page whenever the user switches to a different one. These applications are larger than SPAs, have no page count restrictions, and provide in-depth details on the company’s goods or services.

3.3 Progressive Web Apps (PWAs)

Progressive Web Apps (PWAs) are the most popular class of web application development technologies that resemble mobile applications. They may be downloaded from the Google Play Store and the Microsoft Store and are also known as cross-platform web applications. By employing the latest browser APIs and progressive enhancement techniques, they deliver a native mobile app experience.

The primary goals of PWA are to improve web apps’ responsiveness and speed on slow internet connections. These programs’ push notification-sending abilities, instability, offline functionality, and simplicity of syncing are some of their benefits.

Pinterest, Uber, Starbucks, and Spotify are some significant instances of Progressive Web Apps (PWAs).

4. What is Web Application Development?

Web application development is the process of creating an application that can be accessed through a web browser utilizing client-side and server-side programming.

The process of creating web application development technologies starts with the developer trying to solve a particular issue, followed by designing the web app by selecting the best development framework. The developer then checks the solution before launching the web application.

Application Programming Interfaces (APIs) and Software Development Kits (SDKs) are two essential technologies in contemporary software development. Both aim to extend and enhance the capabilities of the program.. An SDK and API, however, both have unique use cases and goals to address particular issues in software development pipelines.

In this article, we’ll go deeper into each type to have full knowledge about what they are, how they operate, and what benefits they assist.

5. API and benefits of API

5.1 Define API

The API is a series of protocols and tools enabling the development of software for web application development technologies. It is a collection of precisely defined communication techniques between different components of the software. Clients or IT outsourcing, especially software outsourcing in Vietnam, have established APIs.

APIs come in a varie ty of forms and sizes. A reader’s browser would most likely employ several API sets to turn user instructions into useful functions, request data from servers, render that data into a visible format for the user, and check the performance of their queries.

The fact that APIs allow for consistency is maybe the most crucial. The computer was a big sea of orders and instructions in the early days of programming, loosely written and rarely documented. With the development of contemporary computers, APIs have enabled consistent code in stable settings, enabling reproducible functions to be supplied consistently and predictably every time a request is filed.

5.2 Benefits of API

The following are some ways that APIs can bring to you huge benefits in web application development technologies:

  •       integrating many software programs to improve the overall product offering.
  •       automating the development cycle to make it shorter.
  •       lowering the number of resources that would otherwise need to be set aside for internal tasks.
  •       enhancing consumer trust and brand recognition.
  •       delivering new services to customers as effectively as possible.

6. SDK and benefits of SDK

6.1 What is SDK?

SDK is an abbreviation for “Software Development Kit,” which is a terrific way to think about it – a kit. Consider constructing a model automobile or plane, a complete kit of components is required to build this model, including the kit components themselves, the tools needed to put them together, and assembly instructions,…

An SDK or devkit works similarly, offering a set of tools, libraries, necessary documentation, code samples, methods, and/or guidance that allow developers, IT outsource teams to create software applications for a certain platform. If an API is a collection of building bricks that allows for the production of anything, an SDK is a full-fledged workshop that allows for creation well beyond what an API would enable.

SDKs are the source of practically any software with which a modern user might interact. From the web browser you use to the video games you play at the end of the day, many programs were designed with an SDK before an API was utilized to interface with other programs. Because of its benefits, there’s a lot of software outsourcing in Vietnam using SDK in every project.

6.2 Benefits of SDK

SDKs facilitate the work of developers by offering the following:

  •       Access to the instructions and component pieces needed to construct software: For instance, a retail SDK that directs everything you’d want for your app (e.g. order, payment, save, etc.).
  •       Faster and more seamless integrations SDKs offer quick access to necessary information and streamline necessary standard operations.
  •       Shorter product development cycle and quicker product deployment and market entry.
  •       Built-in assistance and knowledge: You don’t need to look up solutions or pay additional staff because SDKs already have knowledge in the form of written code and support documentation.
  •     controlling costs All of the aforementioned things make it easier for you to more precisely adhere to a budget both during development and after deployment.


Both API and SDK are critical components of the software development process. As the name indicates, an API serves as an interface between multiple applications or platforms, allowing multiple software programs to interact. They often provide specs that may be utilized to interface between various software programs. The SDK, on the other hand, is made up of development tools and pre-written code that developers may utilize to create their apps. The SDK often minimizes the labor and time necessary for developers to create their custom code to construct software applications.

APIs may include routines, data structures, protocols, and object class definitions that allow various programs to interface with one another. The SDK often comprises files or APIs in the form of complicated hardware to ease interaction with embedded devices. The SDK is critical in minimizing labor duplication and saving developers time while developing new software applications. An API often comprises a set of rules and criteria, which software programs will adhere to promote smooth interaction. 

Are you challenged to pick between SDK and API? No, in fact, an SDK frequently includes at least one API, as was already said. These two assist you in various ways, but they can and frequently do so in combination. APIs explains how various platforms interact with one another. They act as facilitators, one of the tools in a full toolkit, facilitating contact via specifications (protocols).

SDKs are the entire toolkit. They offer everything needed to create new software for a certain platform or programming language, going above and beyond facilitation (though they do contain it). The following part would help you find out the finest solutions.

8. When will the developer use SDK or API?

When creating applications, IT outsource developers always use the SDK. Furthermore, some SDKs are specially intended for various platforms, such as an Android SDK, which is dedicated to Android applications. The API allows you to interface with other programs or platforms using a variety of techniques and protocols.

In brief, all developers who work in software outsourcing in Vietnam will use the SDK to design any web application development technologies. The API integration will be used when you need to interface with other third-party service providers (application/platform) that may or may not be included in the SDK.
