How to fetch all repositories with specific topic, using GitHub GraphQL API?

Question

I am trying to fetch all my repositories that contain topic "portfolio" using Github GraphQL API.

For now, I found only how to fetch all repos on github with a specific topic, like so :

{
  search(type: REPOSITORY, query: "topic: portfolio", last: 50) {
    repos: edges {
      repo: node {
        ... on Repository {
          url
        }
      }
    }
  }
}

And I know how to fetch all repos for a specific user, like so:

{
  user(login: "VitFL") {
    repositories(last: 50) {
      repos: nodes {
        url
      }
    }
  }
}

But I have no idea how to combine those queries, so I could receive all repos with topic "portfolio" for a specific user.

Does anyone know how to achieve this result?

Answer 1

Using search(), a user argument can be added to the query value.

Also, the whitespace after the colon should be removed, i.e. topic: portfolio -> topic:portfolio. You will notice far more results with this change.

{
  search(type: REPOSITORY, query: "user:VitFL topic:portfolio", last: 50) {
    repos: edges {
      repo: node {
        ... on Repository {
          url
        }
      }
    }
  }
}
