What is koa-logger?

koa-logger is a middleware for Koa that provides logging capabilities. It logs HTTP requests and responses, including details such as method, URL, status code, and response time. This can be useful for debugging and monitoring purposes.

What are koa-logger's main functionalities?

Basic Logging

This feature allows you to log basic HTTP request and response details. The code sample demonstrates how to set up koa-logger in a Koa application to log incoming requests and outgoing responses.

const Koa = require('koa');
const logger = require('koa-logger');
const app = new Koa();

app.use(logger());

app.use(async ctx => {
  ctx.body = 'Hello World';
});

app.listen(3000);

Custom Logging Format

This feature allows you to customize the logging format. The code sample shows how to use a custom logging function to format the log output according to your needs.

const Koa = require('koa');
const logger = require('koa-logger');
const app = new Koa();

app.use(logger((str, args) => {
  console.log(`Custom Log: ${str}`);
}));

app.use(async ctx => {
  ctx.body = 'Hello World';
});

app.listen(3000);
