Features

• Uses the fastest router: Julien Schmidt's httprouter
• Uses gofrs uuid package to guarantee unique request ids
• Uses MrZ's go-logger for either local or remote logging via Log Entries (Rapid7)
• Uses MrZ's go-parameters for parsing any type of incoming parameter with ease
• Added basic middleware support from Rileyr's middleware
• Added additional CORS functionality
• Standardized error responses for API requests
• Centralized logging on all requests (requesting user info & request time)
• Custom response writer for Etag and cache support
• GetClientIPAddress() safely detects IP addresses behind load balancers
• GetParams() parses parameters only once
• FilterMap() removes any confidential parameters from logs
• ...and more!

Package Dependencies

• Julien Schmidt's httprouter package
• Rileyr's middleware package
• gofrs uuid package
• MrZ's go-logger and go-parameters package

Library Deployment

goreleaser for easy binary or library deployment to Github and can be installed via: brew install goreleaser.

The .goreleaser.yml file is used to configure goreleaser.
