download-url-in-go

Retrieving content from a URL at intervals (example of using GoLang).

author: Adam Nielski

The app uses the following Go packages:

• Web framework: echo
• Configuration: viper
• Dependency management: dep
• Testing: testify

Project Structure

The download-url-in-go project has six main packages:

• bindings: The bindings directory will hold all of the protocol-specific data bindings for the application, such as form submission, query string, and JSON representations of application input
• handlers: The handlers package is where you store all your Echo web application-handler code and business logic for the application
• models: Within an application, you’ll have application-specific data structures that you will need to persist to a database. The models package will house the application-specific types.
• renderings: The renderings package will contain all the data structures and types that will be serialized back to the caller through the http.ResponseWriter
• vendor: contains all third party libraries

Dependency inversion principle is followed to make these packages independent of each other and thus easier to test and maintain.
