Query to return Array 2D

[albertcito]

Versions:

• graphql-laravel Version: 4.0.0
• Laravel Version: 6.0
• PHP Version: 7.3

Question:

I have a matrix in the DB, And I would like to return a Array 2D type. But as far as I know, I just can return a simple array, but not an array 2x2. This is the Cell type

type Cell {
  row: number,
  col: number,
}

I can return it as an array of Cell, but I don't know if is possible to return a Array 2D like this one:

[
    [{row:0, col: 0}, {row:0, col: 1}, {row:0, col: 2}],
    [{row:1, col: 0}, {row:1, col: 1}, {row:1, col: 2}]
]

Looks like GraphQL doesn't support it: graphql/graphql-spec#423

Yes, this is one of the limitations. To emulate tuples you would need a separate type and give the fields names.

The other limitations is that you can't project a hash (in PHP: array with dynamic keys) either.
