04/15/2019, 12:30 PMIs it possible to use nested queries with TypeScript and prisma-client-lib? Previously with prisma-binding, it was possible to pass the info variable to the binding, but the prisma-client-lib lacks this capability. This blog https://medium.com/@lukehamilton/nested-relations-in-prisma-971e060a16ab helps me so far, I only have to extract the fragment from the info parameter. Are there already solutions?

// This function constructs the user query from the info parameter.
// TODO(till): This is a quick fix, wait for the Prisma client to support nested queries on its own.
export function infoToUserQuery(info, current: string = ‘’): string {
if (current === ‘’) {
info = info.fieldNodes[0].selectionSet.selections;
}
current += ‘{ ‘;
for (const selection of info) {
current += selection.name.value + ’ ‘;
if (selection.selectionSet) {
current = infoToUserQuery(selection.selectionSet.selections, current);
}
}
current += ‘}’;
return current;
}

There is a better way to do this using type resolvers.
