Reading documents

If you've been following along with the previous examples, your database will now have a table called fake_data that contains 100 documents. Now that we've got some data in our database, let's see how we can read data from RethinkDB from a Node.js script.

We've already seen how RethinkDB provides us with the filter command to read data from the database based on a condition. In the previous chapters, you learned to use this command in the web interface to perform read queries on our datasets.

However, sometimes you may want to read all the data from a table without any filtering. To do this, you just need to select the table from which you want to read, and RethinkDB will give you a cursor to access the data. You can then use the cursor to create an array that includes all the results.

This example reads and prints all the documents from the fake_data table:

r.table("fake_data").run(conn, function(err, cursor) {
    if (err) throw err;
    cursor.toArray(function(err, results...
