The Web Programming Era

In the past, programmers wrote code and saved it in text files on their own computers. To share programs with friends, they would have to copy their code to each friend's computer. Nowadays, you can save your code on the web, and to share a program with someone, you just send them a link. We call these programs "web apps", short for web application.

Create Your Own Web App with AppJet

First you need an account to save your work. If you already have an AppJet account, then click "sign in" link on the right side of the blue bar at the top of this page.

If all went well with the above sign-up process, you should have your own working web app! Once you learn a bit of programming, you will be able to create your own apps to do cool, useful, and/or entertaining things (ideally all three at once).

For a sneak peek of what kinds of apps you'll soon be able to write, take a look at the app directory. It's full of apps people have recently published. For any app, you can see the code behind it, and even "clone" the app to create your own, based on the same code. Some of the code may look confusing at this point, but stick with this guide and you'll soon understand all of it.

If it's a "web" app, where does the code you write actually get run?

When you create an app with AppJet, your code is stored on AppJet's servers. When you or someone else visits your app, the servers run the code, and return the output (usually HTML) to the web browser, which displays it. This is called "hosting" your app, and AppJet currently provides web hosting for apps free of charge.

For a detailed look at this process, look ahead the diagram on the lifetime of a request lesson.
