Tell us about GraphQL?

Question

JavaScript

Please tell us about GraphQL and how you prepare it. I got acquainted with the documentation, this thing interested me, but it seems to me that it is very empty. How do you use conditions when sampling, set limits, etc. etc. Please share your knowledge.

Answer 1

I like the Relay approach for pagination . Actually, it doesn’t really differ from other sampling conditions, something like this:

query {
  users(first: 10, order: "id") {
    totalCount,
    edges {
      cursor,
      node {
        id,
        name,
        lastAt,
        avatar {
          original,
          preview
        }
      }
    },
    pageInfo {
      startCursor,
      endCursor,

      hasNextPage,
      hasPreviousPage
    }
  }
}

In this example, we get the first 10 records sorted by id. PageInfo stores information whether there is a next / previous page and cursors that are passed to the before or after parameters.
