Winston not Logging to console in typescript
When you instantiate a new Logger instance you need to provide it a list of transports so it knows where to send the logs:
var logger = new (winston.Logger)({
transports: [
new (winston.transports.Console)(),
new (winston.transports.File)({ filename: 'somefile.log' })
]
});
Well,
thanks to the hint of @idbehold , I found that a plain and easy:
import * as winston from "winston";
winston.info('Now my debug messages are written to the console!');
works for the default logger..
This is the Typescript way to import Winston.
First, be sure you have installed the typing :npm i -D @types/winston
Then, in your script.ts
import { Logger, transports } from 'winston';
var logger = new Logger({
transports: [
new transports.Console(),
new transports.File ({ filename: 'somefile.log' })
]
});
In genral, you can import all constants and types without using winston.<...>
before.
