This is a simple application illustrating how to get started with Fission.
It only has one dependency: the webnative SDK. Everything else is plain HTML, CSS and JavaScript. All the functionality related with Fission is contained in a single file; fission.js.
You can find the documentation in the fission.js file, and some general Fission concepts in the glossary.
The index.html and main.js files are not documented, but they should be fairly easy to understand if you're already familiar with HTML and JavaScript. The application doesn't have any custom CSS as it is using a classless CSS framework called Simple.css.
If you want to play around with the application, you'll need to log into a Fission account.
If you want to modify the code, you'll also need to serve the application in a url. You could just open the index.html file in a browser, but unfortunately that will not work because the authentication flow performs a redirect and that won't work with a website being served with the file:// protocol.
Any tool to run a local server will work, for example you could use ViteJS:
npm install -g vite
vite .
