Flag templates

Overview

This topic explains the different types of flags available in LaunchDarkly, and how to customize flag templates. Flag templates are project-wide default settings for different types of flags.

Modifying flag templates

LaunchDarkly projects have groups of default settings, called "templates," for each type of flag. When you create a flag from a template, that template's default settings appear as pre-set configuration options.

You can modify default flag templates. LaunchDarkly applies those default settings to new flags of the same template type within the project. Updated default settings only apply to flags created after you modified the default settings. If you change a flag template's default settings, LaunchDarkly does not retroactively apply the new defaults to existing flags.

To modify a flag template:

1. Navigate to the Account settings page.
2. Click into the Projects tab, then the Flags tab. The template for each type of flag appears.
3. In the "Global Settings" section, select the SDKs using Mobile Key and SDKs using Client-Side ID checkboxes to determine whether new flags should be available to mobile and/or client-side SDKs.
4. Click Edit on the flag template you wish to modify and follow the section for that flag template:

• Custom flag template settings
• Release flag template settings
• Kill switch flag template settings
• Experiment flag template settings
• Migration flag template settings
