MongoLogger

MongoLogger was created after an immense amount of frustration using Winston to log requests and errors to MongoDB. Nothing was formatted the way I wanted it to be so I created MongoLogger.

Example Log

An example of a logged document with all features enabled can be found here

Getting Started

Run npm i express-mongo-logger

var mongoLogger = require("express-mongo-logger");
var express = require("express");
var app = express();

app.use(
	mongoLogger({
		mongoConnectionString: "mongodb://<User>:<Password>@<Host>:<Port>/><Database>"
	})
);

app.get("/", async function (req, res, next) {
	res.send(`Hello World!`);
});

app.get("/404", async function (req, res, next) {
	res.status(404).send(`The requested resource cannot be found!`);
});

By default all requests will be logged. It is highly recommended to define minStatusCode:400 to only log errors.
