Feature Flagging - Implementation Design - Detailed

Introduction and Overview

Feature flagging is needed to decouple the deployment of code from the release of features. This allows teams to deploy code more frequently without having to release new features to all users at once. This can be beneficial for a number of reasons:

• Reduced risk: Feature flagging allows teams to test new features in production with a small subset of users before releasing them to all users. This can help to reduce the risk of deploying new features that have bugs or other problems.
• Faster innovation: Feature flagging allows teams to release new features more quickly without having to wait for the entire development cycle to be completed. This can help teams to stay ahead of the competition and meet the needs of their users more quickly.
• Improved user experience: Feature flagging allows teams to target new features to specific groups of users. This can help to improve the user experience by ensuring that users only see features that are relevant to them.

Feature Flagging - Implementation Design

 

Projects:

Projects represent the different products or applications that your team is developing.
Each project has a unique identifier.

Environments:

Environments represent the different stages of your development lifecycle, such as development, staging, and production.
Each environment has a unique token.

Features:

Features represent the different functionalities that your team is developing or has already developed.
Each feature has a unique identifier.

Usage:

1. Developers need to create a feature flag for each new feature that they are developing.
2. When creating a feature flag, developers need to specify the following:
• The name of the feature
• The description of the feature
• The environment(s) where the feature will be available
• The default state of the feature (enabled/disabled)
3. Once a feature flag is created, developers can start using it in their code.
4. To use a feature flag, developers need to check the state of the flag before executing the code that implements the feature.
5. If the feature flag is enabled, the code will be executed.
6. If the feature flag is disabled, the code will be skipped.
