Is Dgraph powerful for hold the User System?

it’s suggested to use auth0 in the official website, but I prefer to do it myself, store users in dgraph directly. All in dgraph is comfortable to me, I’m not sure if it is powerful or suitable for this, thanks

You can do it.

But what this question is related to? Dgraph or GraphQL?

Dgraph, I use dgraph only.

I don’t know what people think, I find myself that graphql is just a query langue, do things limited, even that, itself is too tedious. but dgraph is a database of dream.

GraphQL is amazing too. It is front-end friendly, so it is nice for small businesses and startups. But sure, DQL is thousand times better in some ways.
