Your turn

If you want to take your code to the next level, from CLI to GUI, then you found the right toolkit.

With the Atlas toolkit, you transform your programs in modern web applications (SPA) without the usual hassles:

• no JavaScript to write; only HTML(/CSS) and Java,
• no front and back end architecture to bother with,
• no web server (Apache, Nginx…) to install,
• no need to deploy your application on a remote server,
• no incoming port to open on your internet box or routeur.

The Atlas toolkit is written in pure Java, with no native code and no dependencies, allowing the Atlas toolkit to be used on all environments where Java is available.

And simply by running them on a local computer connected to internet, applications using the Atlas toolkit will be accessible from the entire internet on laptops, smartphones, tablets…

Content of the repository

The atlastk directory contains the Java source code of the Atlas toolkit.

atlastk.jar is the file you have to reference in the classpath in order to use the Atlas toolkit in your own program.

The examples directory contains some examples.

To run an example, go inside its directory (Blank, Chatroom…) and launch:

• under Windows: java -cp .;../../atlastk.jar <Name> (with semi-colon as classpath separator),
• under other platforms: java -cp .:../../atlastk.jar <Name> (with colon as classpath separator).

where <Name> is the name of the example (Blank, Chatroom…).
