Feature flag targeting
Configure your feature flag rollout rules and define the audience that should receive a given flag variation.
Progressively comes with two main ways to target the users that are supposed to receive a specific variant of your feature flags: The quantitative way and the qualitative way (they are not exclusive).
Any of the quantitive or qualitative rules will only apply if the feature toggle is activated. If it's not activated, every single user will receive the
false variation of your flags.After a feature flag creation, you can decide which percentage of your audience should receive the
true variation of your feature flag using the slider in the "Audience" pane:ge
You can also choose to add additional eligibility constraints.
For example, it's possible to create rules that will allow 50% of the users that match the following two rules to see the
true variant of the flag:- People with an email containing @progressively.app
- People with an email containing @bestfriends.com
There is a last way to target a specific set of users. I tend to call these users "Joker Users". Let me illustrate this with an example.
Imagine that you are building a very new fancy feature that you are about to roll out. But you lack confidence, and you want to roll it out slowly. Let's say 10% of your audience for starting.
You may wonder:
I want to be part of these 10% people so that I can play with my team with this new feature
With the Eligibility Audience rules, it's not possible, since they aim to add another level of filtering, not a level of opening.
Additional audience aims to handle this particular case: people matching at least one of the rules are not subject to the percentage rollout and will receive the configured flag variation.
It's a more permissive set of rules that bypasses any qualitative or quantitative rules.
