A single page application (or SPA) is a page of HTML which includes or loads all the necessary CSS and Javascript to enable a set of application behaviors.

Tank makes an ideal host for single page applications because you can host the application and the data or content that the application uses in the same place while managing both over the API.

You can make an SPA in two ways:

• Putting the HTML and other files in a tank and then accessing the HTML file directly.
• Creating a tank where the main HTML file is named app and necessary assets are kept in the same tank. Then use that tank in a comp.

tsapp, in tiddlyweb_mode, can be used to help build SPAs on Tank.
