Tips for bringing in Cassandra driver types in TypeScript?

In the documentation for the Cassandra driver, they provide code examples like this:

const Uuid = require('cassandra-driver').types.Uuid;
const id = Uuid.random();

However, when attempting to use this in Visual Studio Code, the Uuid class type is not recognized.

I tried using ES6 style imports like this:

import cassandra from 'cassandra-driver'

How can I properly import the Uuid type so that typescript recognizes it correctly?

Using a type alias seemed to initially solve the issue. Is this the recommended approach? It feels a bit verbose if I need to do this for multiple types.

type Uuid = cassandra.types.Uuid

Update: Unfortunately, using a type alias did not fully resolve the problem as I was unable to call Uuid.fromString(...).

Answer №1

When retrieving a value from the module, it's important to also consider the type. Using require requires you to use import instead in order to maintain the correct typings. Otherwise, you will only get the require function from node, which returns any and removes all valuable types.

import cassandraDriver = require('cassandra-driver');
type Uuid = cassandraDriver.types.Uuid;
const Uuid = cassandraDriver.types.Uuid;
const id = Uuid.random();

interface Test {
    id: Uuid
}
