Nodejs: Cannot Read property 'city' of undefined

Question

i am using Express & Ejs & body-parser ; Server js:

app.post('/', function(req, res) {

       if (!req.body) return res.sendStatus(400)
 console.log(req.body)

});

My Index.Ejs File

<div class="container">
                <fieldset>
                  <form action="/" method="post">
                    <input name="city" type="text" class="ghost-input" placeholder="Enter a City" required>
                    <input type="submit" class="ghost-button" value="Get Weather">
                  </form>                       
               </fieldset>
              </div>

i get this Error in console:-

Cannot set headers after they are sent to client

I haven't worked with EJS but I think you should use the `body-parser` middleware for Express. — Eyal, Mar 11 '18 at 11:19
