go-feature

Package feature provides a simple mechanism for creating and managing feature flags.

See ./examples/hello for an example.

Trying it out

• run make && ./example-hello
• visit http://localhost:22022/hello in your browser
• run curl -XPOST 'http://localhost:22022/features/scream?enabled=true'
• visit the /hello page again, and it will display a "louder" message (i.e. with more UPPERCASE letters)

Additional things to try out:

• http://localhost:22022/features: Displays the list of features, and their state. If visited in a browser, it will provide a tiny user-interface for setting parameters.
• curl -XPOST 'http://localhost:22022/features/surprise?enabled=true&ratio=0.75' (note the "ratio" parameter)

Building and testing

The Makefile is set up to work with a project-local GOPATH. Thus you can just run make to build the example, or make test to run the tests.
