Add schema support for maps about dynamodb-toolbox HOT 6 CLOSED

Any update on this one? Would be such a great feature as otherwise we lose all the awesome aliasing features in the deeper nested maps 😢.

from dynamodb-toolbox.

It would be handy to support list schema too. For eg.

someList: { type: 'list', schema: { name: 'string', enrolled: 'boolean' } }

the expected input for this would be:

const list = [{ name: 'foo', enrolled: true}, { name: 'bar', enrolled: false}]

I am happy to create the PR for this. Let me know.

+1 to this feature, typing on maps would be super useful

To add to this being able to alias to a non-nested field would be super useful it doesnt seem like its possible right now?

I have here an example "Giveaway" model that has a winners object with the current winner and past winners (if any). And would like to alias winners.current to "winner", not sure if that is possible:

const giveaway = new Entity({
  table,
  name: 'Giveaway',
  attributes: {
    id: { partitionKey: true, prefix: 'Giveaway#' },
    sk: { sortKey: true, default: 'Giveaway#', hidden: true },

    winner: { type: 'map', dependsOn: 'winners', default: (item) => item.winners.current, save: false },
    winners: { type: 'map', default: { current: {}, pastWinners: [] } }
  }
})

Whenever I parse an item the winners.current value is correct, however, the default function for winner never gets called so the "winner" object is not populated. I assume I could probably put save to true and it would work via duplicating the value but not ideal.

Done in v1 😎
