Setting up the GraphQL backend - CivicTechFredericton/mealplanner GitHub Wiki
Make sure you set up the postgrahpile backend first. The graphql server depends on that.
Install node using the installer from nodejs.org that matches your OS (Windows/Mac/Linux).
Open a command prompt or powershell and CD to the mealplanner/backend
Install the dependencies if you haven't already:
npm install
Now run the graphql server:
npm start
The server should now be available at http://localhost:4000/graphiql
