Getting started with Express.js; you can use this middleware to log all incoming requests. This helps you verify that your server is running and the data it is receiving.

app.js

//app.use() adds a middleware
//middleware tries to handle every request
//this middleware is used for logging
app.use(( req, res, next ) => {
  let request = req.method.toUpperCase() +' '+ req.url

  if( Object.keys( req.query ).length ){
    request += '?'+ querystring.stringify( req.query )
  }

  if( Object.keys( req.body ).length ){
    request += "\r\n"+ JSON.stringify( req.body )
  }

  console.info( `--------------------------------------------------------------\nRequest: ${request}` )

  //next() tells Express to find the next request handler
  next()

  //NOTES:
  // #1 - you can put some logic here, but it should only handle global tasks like authentication and parsing formats
  // #2 - you should not put your database logic here
})
