Manage Shared Config Constants

Shared config constants are global values managed in Strapi that are available in every questionnaire. They are used for regulatory thresholds, company branding, and other values that appear across multiple insurance products.

Prerequisites

• Access to Strapi CMS (shared-config content type)
• Familiarity with interpolations (see Configure Interpolations)

Current shared constants

The following constants are currently defined:

Constant	Current Value	Description
featherName	Feather Insurance	Company display name
privateHealthInsuranceThreshold	77400	Annual income threshold for private health eligibility
miniJobThreshold	7236	Annual mini-job income threshold

Steps

1. Reference shared constants in question text

Use the constant name directly in double curly braces — no prefix needed:

You are eligible for private health insurance if your annual
gross income exceeds {{privateHealthInsuranceThreshold}} EUR.

This differs from questionnaire-specific constants, which require the {{constants.myConstant}} prefix.

2. How shared config is injected

During sync, each questionnaire file merges shared config with questionnaire-specific constants:

constants: { ...sharedConfig, ...constants },

Shared config is loaded first, then questionnaire-specific constants override any matching keys. This means a questionnaire can override a shared value if needed.

3. Update a shared constant

1. Open Strapi and navigate to Content Manager > Shared config.
2. Edit the value you want to change.
3. Publish the change.
4. Notify engineering in the #birdhouse Slack channel so they can run a content sync.

4. When to update shared constants

• Annually: Regulatory thresholds (e.g., privateHealthInsuranceThreshold, miniJobThreshold) change with each calendar year
• Rebranding: Company name changes
• Regulatory changes: New thresholds or limits introduced by law

5. Shared config vs questionnaire-specific constants

Feature	Shared config	Questionnaire constants
Scope	All questionnaires	Single questionnaire
Strapi location	Shared config content type	Questionnaire metadata > constants
Interpolation syntax	{{constantName}}	{{constants.constantName}}
Override behavior	Can be overridden per questionnaire	Takes precedence over shared config

Tip

The shared config also supports internal (code-defined) constants via internalSharedConfig.ts. These are merged with Strapi values at runtime and can use getters for computed values.

Caution

Changing a shared constant affects every questionnaire that references it. Always verify the impact across all verticals before publishing updates to production Strapi.
