Please refer to the batch-loader documentation for more details.
Here's an example of a Feathers server that uses feathers-plus/batch-loader.
`js
const BatchLoader = require('@feathers-plus/batch-loader');
const { getResultsByKey, getUniqueKeys } = BatchLoader;
const usersBatchLoader = new BatchLoader(
keys => app.service('users').find({ query: { id: { $in: getUniqueKeys(keys) } } })
.then(result => getResultsByKey(keys, result, user => user.id, '!'))
);
app.service('comments').find()
.then(comments => Promise.all(comments.map(comment => {
// Attach user record
return usersBatchLoader.load(comment.userId)
.then(user => comment.userRecord = user);
})))
