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 nx run edu-hub:apollo

For rent-a-scientist:

cd frontend-nx && GRAPHQL_URI=http://localhost:8080/v1/graphql yarn nx run rent-a-scientist: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 nx run edu-hub:apollo

Generated Files Location

• edu-hub: frontend-nx/apps/edu-hub/queries/__generated__/
• rent-a-scientist: frontend-nx/apps/rent-a-scientist/queries/__generated__/
