Debug your express app using the console.

Install

Install the chrome extension from the chrome webstore, or use Firefox Developer Edition which now natively supports the chrome logger! 👏

$ npm i express-chrome-logger --save

Example

var express = require("express");
var app = express();

app.use(require("express-chrome-logger"));

app.get("/", function(req, res) {
  res.console.log("Hello from your server :)");

  res.console.groupAs("Request", function () {
    res.console.dir(req);
  });

  res.console.assert(
    req.headers["user-agent"].search(/Chrome/) !== -1
    , "Not using Chrome"
  );

  res.send("");
});

app.listen(5000);
