As with any fully rounded web application framework, the developer should have the ability to serve static and dynamic assets. With Echo, you have the ability to serve static content with the Static Echo instance method, as well as the ability to serve individual files with the File Echo instance method.

Often, it is not enough merely to serve static content. Echo also provides the ability to serve dynamic templates, which can be populated with dynamic data, as shown in this chapter. Within this chapter, we have shown not only how to render dynamic data from templates, but also how to call back into Echo from within the templates themselves.
