MongoDB - How to filter a nested object by query params (e.g. metadata object that has different parameters like page)

find-by-query-param.js

export default async function(req: NextApiRequest, res: NextApiResponse) {
  const {
    query
  } = req

const { db } = await connect()

// Finds all posts where the `metadata` property is an object
// and contains properties like `category`.
const posts: Posts[] = await db
  .collection('posts')
  .find({
    'metadata.dateModified': query.dateModified,
    'metadata.category': query.category,
  })
  .toArray()

// [ { id: 1, name: 'Blog Post', metadata: { dateModified: '2020-02-04', category: 'Uncategorized' } } ]
