: Document the breaking changes and migration path.The changes to the type system and environment variable handling represent breaking changes. Consider:
- Adding migration documentation for existing users
- Updating the README to reflect the new port parameter requirement
- Documenting the new NEXT_PUBLIC_CHAT_API environment variable
Would you like me to help draft the migration documentation or update the README?

: Enhance documentation and add URL validationThe implementation looks good, but consider the following improvements:
- Expand the description to clarify all valid use cases beyond Express
- Add validation for the URL format when the env var is consumed
Update the description to be more comprehensive:
- description: - "The API for the chat endpoint. Set when using a custom backend (e.g. Express). Use full URL like http://localhost:8000/api/chat", + description: + "The API for the chat endpoint. Set this when using any custom backend implementation (e.g. Express, FastAPI, etc.). Must be a full URL including protocol and path (e.g. http://localhost:8000/api/chat). This value will be exposed to the client-side.",

: Verify the impact of the InstallAppArgs type change.
The addition of port
to the omitted properties list indicates that it's now a required property in InstallTemplateArgs
. This change, combined with the removal of customApiPath
, represents a breaking change that could affect existing consumers.
Let's verify the related changes and their impact:
✅ Verification successful
Port configuration has been simplified and standardized across templates
The changes to InstallAppArgs
type are part of a broader improvement in port handling:
-
The removal of
customApiPath
and addition ofport
to omitted properties is a positive change that:- Standardizes port configuration through environment variables (PORT=8000 by default in Express)
- Removes the need for manual API path construction
- Maintains backward compatibility as the port configuration is handled at the template level
-
The git diff shows that the
port
parameter was also removed from thecreateApp
function, confirming that port handling has been moved to the template level where it belongs.
This is not a breaking change as it actually simplifies the API and moves configuration to a more appropriate location in the templates.

: Verify impact of environment variable consolidation
The PR moves NEXT_PUBLIC_CHAT_API
from frontend env file to framework envs. While this consolidation makes sense, we should verify that existing implementations aren't affected.
Let's check for any existing usage of this variable:
✅ Verification successful
Environment variable consolidation is safe to proceed
The variable NEXT_PUBLIC_CHAT_API
is used consistently across templates as an optional configuration with a fallback to window.ENV.BASE_URL
. Moving it to framework envs is a safe consolidation since:
- No .env files currently define this variable
- Usage in code properly handles the case when the variable is undefined
- The implementation in both templates is identical and follows the same pattern
- The variable is now properly documented in the framework-specific section where it belongs
