Types of Web Applications
Three basic types of web applications are client-side, server-sider, and single-page apps. Type of app is selected depending on the type of app you want to build and the features it is supposed to have. Let’s have a look at each type of web app and understand its working.
Client-Side Web Apps
Client-side web applications are the apps with heavy front-end development working. Meaning, interactive UI elements, changing UI and visuals, and elements designed to grab users’ focus. Client-side apps prefer giving users high-performing apps.
The data in such apps is loaded dynamically when the app starts up. Close to none buffering happens because of client-side rendering at load time. Making client side apps highly responsive and fast.
Server-Side Web Apps
The apps that are on the heavier side of business logic or backend end development are called server-side apps, because more logic and functioning is happening at the server side. In this type of development, developers are supposed to write backend code, apply logic to connect the backend to frontend and database, build and maintain databases, maintain and connect the app to the server, interact with the APIs and third party libraries.
Server side apps work well with static content, while they can work with dynamically changing content as well. Sending requests to change and update the content in the frontend takes time to send, receive, and take action on the request. Server-side web apps are built with high security with multiple browser compatibility.
Client side and server side apps are different from single page apps. In traditional apps, i.e. multi page applications, pages only load when users click on them. Single page apps, SPAs, have the advantage of both server and client side applications.
Just like their name, they are one page apps, that have an infinite scroll, you keep on scrolling and the content keeps on appearing. SPAs do have a little higher loading time, but python developers use techniques like dynamic loading and fast frameworks to cover up for it.
Following are the questions to which you have to find the answers:
- Problem/reason for building the app?
- The type of problems to solve?
- Type of audience will you cater to?
- Potential user expectation from the app?
- How can their needs be catered?
- What type of product will cater their needs?
- How to keep the users satisfied with the app?
Finding answers to these questions will solve half of your problems and help you devise a solution. This solution will not only be targeted to the users, custom made for your audience, but also help cater their needs accurately along with providing them features or services, retaining them for the long term.
Making the plan
With all the answers, strategizing and making a plan becomes easier. The first step is to define project scope, then plan the development to be completed before the deadline. Then select the tools and technologies to be used, define your budget and goals. And, finally, organize the development of different modules to avoid bottlenecks.
Software design - making it beautiful
This is the time to put your idea to reality by making the design prototype. To make the best design, gather the required information from your target audience, making the product future proof. Keep both functional and UI parts of software interesting.
Prototype is an MVP, minimum viable product, equipped with essential features. This helps validate the idea and features directly from customers. MVP is deployment ready release, however if you want to work on a prototype first, get it approved by the client and then develop the initial release, it's also fine.
Writing the code
In CI/CD approach each module is tested as it is developed, then entire software is tested when each module is integrated. QA and testing are very important and no software should be released without passing the QA check. Skipping this step can cause the software to malfunction and even crash, which is bad for business.
At the time of launch and right after it, often the software runs into multiple but small problems. So, at this stage keep your eyes and ears open, listen to the users and monitor the software. Solve any problem at earliest and it will all be good.
Maintenance. Repeat from step 1
Once the app is over to the users small maintenance issues are tackled with time. With big errors or new releases you have to follow from step 1 all the way to the previous step.
