| description | Regenerate TypeScript types from GraphQL schema using Apollo codegen. Use when the user asks to update types, regenerate types, run codegen, after GraphQL schema changes, after database migrations, or after modifying Hasura metadata. |
Regenerate GraphQL Types
Prerequisites
- Hasura must be running and accessible at
http://localhost:8080/v1/graphql
- Start with:
docker compose up hasura (from project root)
Quick Command
Run from the frontend-nx directory with the GraphQL URI:
cd frontend-nx && GRAPHQL_URI=http://localhost:8080/v1/graphql yarn apollo
When to Run
Run codegen after:
- Adding new GraphQL queries or mutations
- Modifying existing queries
- Backend schema changes (new tables, columns, relationships)
- Pulling changes that include query modifications
Troubleshooting
"Connection refused" or similar network errors
Ensure Hasura is running:
docker compose up hasura
Types not updating
Clear and regenerate:
rm -rf frontend-nx/apps/edu-hub/queries/__generated__/*
cd frontend-nx && GRAPHQL_URI=http://localhost:8080/v1/graphql yarn apollo
Generated Files Location
- edu-hub:
frontend-nx/apps/edu-hub/queries/__generated__/
