• I still db modelling confusing but prisma is helping a lot, this is the syntax i need to remember:

model Link {
  id          Int      @id @default(autoincrement())
  createdAt   DateTime @default(now())
  description String
  url         String
  postedBy    User?    @relation(fields: [postedById], references: [id])
  postedById  Int?
}

model User {
  id       Int    @id @default(autoincrement())
  name     String
  email    String @unique
  password String
  links    Link[]
}

Link has a relation to User . Link uses the postedById feild to reference an item in the User table via its id feild in the User table.

• Such a great chapter about implementing authorisation with graphql + node

These are touch points when adding a new table and graphql api endpoint

• update the prisma.schema
• run npx prisma migrate dev to update the prisma db
• run npx prisma generate to update the prisma client libs
• update the schema.graphql file to include any new mutation definitions.
  • Add the signature of any new types.
  • Update any existing types which may rely on the new type
• implement any new mutation resolvers
• Implement any new type resolvers
• Update any existing type resolvers which depend on the new type resolver
• remember to export new mutation and resolvers and include in the ApolloServer instance
