Before

A before hook will receive as an argument the object to be inserted, removed or updated. It should return a promise with a transformed object.

const model = data.model('model', {syncInfo: String, asyncInfo: String}, {
  before: {
    insert: (document) => new Promise(async (resolve, reject) => {
      let asyncInfo;
      try {
        asyncInfo = await getAsyncInfo();
      } catch (error) {
        reject(error);
      } finally {
        resolve({
          ...document,
          asyncInfo,
        });
      }
    })
  },
});

await data.insertOne(model, {syncInfo: 'abc'}); // {syncInfo: 'abc', asyncInfo: 'something'}
