@fastify/one-line-logger

@fastify/one-line-logger helps you format fastify's log into a nice one line message:

YYYY-MM-dd HH:mm:ss.SSSTZ - <level> - <method> <route path> - <message>

A standard incoming request log line like:

{"level": 30,"time": 1660151282194,"pid": 1557,"hostname": "foo","reqId": "req-1","req": {"method": "GET","url": "/path","hostname": "localhost:8080","remoteAddress": "127.0.0.1"},"msg": "incoming request"}

Will format to:

2022-08-11 01:08:02.194+0100 - info - GET / - incoming request

  request.log.info("time to foobar");
  request.log.foo("FOO!");
  request.log.bar("BAR!");
  reply.send({ foobar: true });
});
