Types issue with ESM setup

[iamchathu]

The types seems broken in ESM Typescript setup with module resolution set to "node16".

Pino is commonjs and normally should work with the project without issues.

Here is the reproduction minimal setup.

I think this would do the trick:

import pino from 'pino';

const logger = pino({});

[iamchathu]

Still the error is the same

Type 'typeof import("/home/projects/stackblitz-starters-kuphd3r7/node_modules/pino/pino")' has no call signatures.

3 const logger = pino({});

Agreed, see: https://arethetypeswrong.github.io/?p=pino%409.6.0

So is this currently the only/correct way to use it without throwing TS errors?

import pino from 'pino';

const logger = pino.default({});

I'm building for both CJS and ESM, so I had to do const logger = (pino.default || pino)({}); to both please TS and to make both the outputs work.

you can also manually import { pino } from 'pino'

but more people will end up here as that's not the default VSCode auto-import behavior
