Winston middleware logger for Koa based on
express-winston.
npm install winston-koa-logger
You need to pass a instance of winston to middleware.
const koa = require('koa');
const logger = require('./logger'); // Winston instance.
const winstonKoaLogger = require('winston-koa-logger');
const app = koa();
app.use(winstonKoaLogger(logger));
app.use(function *() {
this.body = 'Hello World';
});
app.listen(3000);
