Just trying this... TypeScript support is not working:

Would also like to use ES module imports, eg:

import type { DatabasePoolConnectionType, SqlTaggedTemplateType } from 'slonik';
import { createPool } from 'slonik';

These are also not working:

Unhandled rejection /Users/k/p/next.js-with-slonik/migrations/2019-10-23T08-22.database-setup.ts:3
import type { DatabasePoolConnectionType, SqlTaggedTemplateType } from 'slonik';
^^^^^^

My tsconfig.json is set up to allow ES Modules: https://github.com/karlhorky/next.js-with-slonik/blob/master/tsconfig.json

Anyway, going to use JavaScript for now.

You probably need ts-node. See the "JavaScript and TypeScript migrations" section of the readme:

Note: if writing migrations in typescript, you will likely want to use a tool like ts-node to enable loading typescript modules. You can either add require('ts-node/register/transpile-only') at the top of your migrate.js file, or run node -r ts-node/register/transpile-only migrate ... instead of node migrate ....

Ah ok, yeah that's a bit much, maybe at some point later...
