Any update about this?

I think the issue is with the import. Changing it to: import TransportStream = require('winston-transport') fixes the issue

does anyone use typescript and this import works?

import winstonGraylog2 from 'winston-graylog2';

I'm suspecting that language level or language feature may be an issue.

I'm failing with such tsconfig:

    "target": "es2016",
    // Enables experimental support for ES7 decorators.
    "experimentalDecorators": true,
    "esModuleInterop": true,

possible fix in #76

I can confirm that I can import this say okay and tsc no longer complain:

import * as WinstonGraylog2 from 'winston-graylog2';

import * as WinstonGraylog2 from 'winston-graylog2';

Hi @glensc Tried this way but then the error exists

Type 'typeof TransportStream' is not a constructor function type.ts(2507)

Do you have esModuleInterop enabled?

• Add typescript example #83 (comment)

@glensc Yes it's enabled in my tsconfig file

Sorry for the late reply guys. I no longer use this library myself, so I didn't really have time to check the issue.
Here is the PR that allows to use the lib with both enabled/disabled esModuleInterop option: #84
