Fetching all documents

After adding the users to the users collection, we can retrieve all or just one of them through the routes that we created in Chapter 8, Adding a Server-Side Framework. Now we just have to refactor them using the same code structure as in the previous section for fetching real data from the database:

1. Refactor the route for listing all user documents with the get method:

// server/routes.js
router.get('/users', async (ctx, next) => {
  let result
  //...
})

2. Inside the get router, fetch all documents from the user collection by using the find API method:

result = await collectionUser.find({
}, {
  // Exclude some fields
}).toArray()

If you want to exclude the fields from the query result, use the projection key and a value of 0 for the field you don't want to show in the result. For example, if you don't want the _id field on each document in the result, do this:

projection:{ _id: 0 }

3. Refactor the route...
