Simple feature flags for Meteor applications
In your templates you can use the featureFlag handlebars helper
enable/disable certain areas or features of your application.
This would look something like this
`{{#featureFlag "newFeature"}}
{{/featureFlag}}` Configuration ------------- ### Meteor.settings The feature flagging configuration should be stored `Meteor.settings.featureFlags`. That means that whenever you use this package, you should run Meteor with a settings file to actually have feature flagging work. ### Feature Flag Handlers Now, by default we packaged a few simple feature flag options, but it's likely you may have some more application specific needs. So we created a way for you to add new ways to feature flag. To do this, you can call the `FeatureFlag.registerFlagHandler` method which takes two parameters: `identifier` and `handler`. The identifier is just an internal identifier. The handler is the function that will actually do the flagging. It accepts one parameter which is the json object representing those feature flags. For example, if you have a feature flag configuration that looks like this `{featureFlags: { "adminWidget": {"users": "[email protected]"}}}` Then the handler will be called with the first parameter being populated with: `{"users": "[email protected]"}` It is your responsibility to verify that the type of feature flagging is valid for your handler. Only return true if you want your handler to enable that feature. Return false otherwise Included Feature Flagging Options --- To get started, we included a couple of options to start feature flagging with. - `users` is quite simply a user (identified by email) or an array of users. If the currently logged in user is matched, the flag is enabled. - `email_domains` is a domain, or list of email domains (eg. `gmail.com`) that will be matched agains the currenly logged in user's email addresses. - `true/false` is simply enabling or disabling a feature with a true or false value.
