TypeScript: Property 'Transport' does not exist on type 'typeof winston'

[dinvlad]

Environment details

• OS: MacOS Sierra (10.12.6)
• Node.js version: 8.11.3
• npm version: 5.6.0
• @google-cloud/logging-winston version: 0.9.0
• winston version: 3.0.0
• typescript version: 2.9.2

Steps to reproduce

1. Attempt to set LoggingWinston as a transport for winston:

import { LoggingWinston } from '@google-cloud/logging-winston';
import { createLogger } from 'winston';

const logger = createLogger({
  transports: [
    new LoggingWinston(),
  ],
});

2. TypeScript throws the following error:

node_modules/@google-cloud/logging-winston/build/src/index.d.ts:19:53 - error TS2339: Property 'Transport' does not exist on type 'typeof winston'.

19 export declare class LoggingWinston extends winston.Transport {
                                                       ~~~~~~~~~
src/server.ts:13:29 - error TS2345: Argument of type '{ level: string; transports: (ConsoleTransportInstance | LoggingWinston)[]; }' is not assignable to parameter of type 'LoggerOptions | undefined'.
  Type '{ level: string; transports: (ConsoleTransportInstance | LoggingWinston)[]; }' is not assignable to type 'LoggerOptions'.
    Types of property 'transports' are incompatible.
      Type '(ConsoleTransportInstance | LoggingWinston)[]' is not assignable to type 'TransportStream | TransportStream[] | undefined'.
        Type '(ConsoleTransportInstance | LoggingWinston)[]' is not assignable to type 'TransportStream[]'.
          Type 'ConsoleTransportInstance | LoggingWinston' is not assignable to type 'TransportStream'.
            Type 'LoggingWinston' is not assignable to type 'TransportStream'.
              Property 'writable' is missing in type 'LoggingWinston'.

It appears that the TypeScript definition for LoggingWinston inherits from a non-existent class winston.Transport. Would it be possible to fix it?

Thanks!

This library doesn't support winston@3.0.0 just yet. See: #84. We are planning to work on that support soon. In the meanwhile you will have to use winston@2.x.

Closing as duplicate.

Thanks, I missed that issue.
