Summary

There is a common set of problems associated with web development. There has been a constant progression of frameworks that have gradually made life easier for web developers by pulling more and more common tasks into framework code, allowing us to focus on the implementation of application logic. Grails is the next link in the chain. It applies a Domain-specific language for web development to the most mature and popular frameworks and enforces some best practices along the way.

By setting up the Grails version of the "Hello World" application, we have seen that the cost of setting up your development environment is almost nonexistent. In the next chapter, we will see how to use the power of scaffolding to perform basic user management tasks without having to write any logic at all.
