Hi, I’m following the Cookbook for Role-based Access Control (RBAC) and came across the following codes:

export const requireAuth = ({ roles } = {}) => {
  if (!context.currentUser) {
    throw new AuthenticationError("You don't have permission to do that.")
  }

I have difficulty in understanding where does the context comes from, appreciate any help.:pray::grinning:

Context is set as a global variable, so you can access it throughout the API code as you please :slight_smile:

HI @andrewlamyw - as @3nvy noted, you can see its implementation here:

https://github.com/redwoodjs/redwood/blob/main/packages/api/src/globalContext.ts

And the reason currentUser is available is because this handler sets it (line 44).

and it’s use the the GraphQLHandler:

https://github.com/redwoodjs/redwood/blob/main/packages/api/src/functions/graphql.ts#L4

in createContextHandler:

https://github.com/redwoodjs/redwood/blob/main/packages/api/src/functions/graphql.ts#L34

and the reason currentUser is available is because it is set on this context at line 44.
