The document discusses Dojo Web Builder, a tool that allows users to easily build Dojo applications in the cloud without needing to install build tools locally. It provides a simple interface where users can select Dojo packages and modules to include, customize build settings, and receive an optimized built file. The tool is hosted on Amazon EC2 and uses a REST API and asynchronous JavaScript builder to process builds. Statistics show it is gaining popularity with over 2,700 builds since launch. Future plans include full AMD support and a Dojo package repository.

3. Who uses the Dojo
builder for their app?

5. So... why do we need a
“Web Builder”?

6. Existing Dojo Build
• Learning curve too steep for many users
• Toolset may put some some users, i.e.
commands lines and shell scripts
• Users from simpler toolkits aren’t used to
“building” JavaScript components

7. Why does this matter?

8. “Dojo is slow....”
