Web applications are stored on a remote third-party server that can be used directly from the browser without downloading anything.

1. Source an idea

It is important that you choose an idea that interests you. Interest is the key to motivation, which is crucial when creating a web application. Web applications are tedious tasks and it is important that you have fun while doing so.

Ask yourself:

How much time do I have to build this app?
What am I interested in?
What apps do I enjoy using?
What do I like about these apps?
How much time/money will this app save or generate for me (as a user)?
How much will it improve my life?

2. Market research

Once you’ve chosen your ideas, it’s important to research the market to see:

If a similar product exists
If a market exists

If you have a similar product, don't worry. This can be a sign that a market exists for your idea. The future competitors laid the foundations and cleared up the market. It's time to rush and steal the thunder.

3. Define functionality

The ...
... more features you add, the longer it will take your web application to build. The longer it takes to build a web application, the more frustration you often experience. One of the most important aspects of creating a web app is having fun, enjoying the journey and celebrating small wins. Only define functionalities that solve the problems of your target market. Your web app is a work in progress and target first is version one. It will still have cool features and will please your users, but you should keep things simple.

4. Sketch your web app

There are many stages of designing a web app. The first stage is sketching.

My favorite and fastest way is to use a notebook (without lines) and a pen / pencil. After following steps 1, 2, and 3, you may have an idea of what the web application is, who the users are and what features it will have. Sketch out the wireframe of your web apps UI - it doesn’t have to be exact - this is just a sketch.

When sketching, consider the following:

Navigation
Branding
Forms
Buttons
Any other interactive elements

5. Plan your workflow

It's time to replace yourself with the user. In step 5, we plan the workflow for the web applications. It's time to go back to step 2 and take a look at your market research. Add a list of competitors and sign up for their free trial. Play quickly with your product. Write down notes about what you think is good and what is bad. Particular attention should be paid to the workflow.

6. Wireframe the UI

Wireframe is the process of creating a design for a web application. Prototyping takes the wire drawing one step further and adds an interactive display. The decision about the wireframe or the prototype is yours. If you have the time, I recommend prototyping as it will make it easier for the web application to communicate during the inspection.

7. Seek early validation

You have now received a nice wireframe/ prototype that visually describes your web application. At this point we would be happy to receive constructive feedback. Ask your friends if they are using the new web app. Start with a small number of representative users. Visit the target market forums, workplace, review the problem with them and present the solution. Try to get in touch with these representatives as they may be your customers.

8. Architect your database

The database is simply a collection of data. The data can be stored on the hard drive or in the server's memory, or in both. You can create a folder on your hard drive, save some documents and call it a database.

A Database Management System (DBMS) is a system that provides you with consistent APIs to (most commonly):

Create databases, update and delete databases
Read and write data to databases
Secure access to a database by providing leveled access to different areas and functions

9. Develop your frontend

The front end is the visual element of your web application. It defines what you see and what you interact with. The interface is developed using HTML, CSS and JavaScript.

10. Create your backend

The backend usually manages your data. This refers to databases, servers and anything else that the user cannot see in a web application. Building your backend is one of the hardest parts of web application development.

The primary jobs of the backend will be to:

Provide HTTP endpoints for your frontend, which allow it to operate on your data. E.g. Create, Read, Update and Delete (“CRUD”) records.
Authenticate users (verify they are who they say they are: aka log them in).
Authorization. When a logged in user makes a request, the backend will determine whether they are allowed (authorized) to perform the requested action.
Serve the frontend

If you have decided on Server Pages, your backend also generates your frontend and makes it available to your users. With a single page application, the backend simply provides your static frontend files.

11. Host your web app

Hosting is the process of running your web application on a specific server.

Buy a domain
Buy/Setup an SSL certificate
Choose a hosting provider

If you choose any of these hosting options, you will almost certainly get everything you need. They have extensive documentation and community support, and are generally reliable options.

12. Deploy your web app

You have found your idea, validated it, designed and developed your web application and selected your host. You are now on the final step. The deployment step includes how your web application moves from your source control on your computer to your hosting.

For starters, you can of course just deploy right from your computer. And that's it. You have created a web application. You should take the time to celebrate this achievement. You are the proud owner of a new web application.
