title: How to configure an SSL certificate for an application that runs in Express?
body: <p>I'm trying to configure the Express server I have created, to pass the SSL certificate and go from http to https.</p>
  
  <p>I read the Express documentation but I can not find the solution. They proposed things to me like Lets Encrypt but it does not support Node.js I do not know if I should modify the hosts file, which I already modified to run the application, or what I have to do. I saw a form, but it only works on Unix system. I show the way in which I have configured the file of the server in case they can help me, it took three days looking for ways to do it without success. The ones I saw do not support Node.js. Thank you</p>
  
  <blockquote>
    <p>I EDIT THE QUESTION:
    Sorry for not including more details, the question is that my application is not in production and my domain is provisional: michaelgram.test. I think that with that Lets Encrypt does not grant me the certificates. I do not know what else to do.The issue is that the application is hosted locally, on my computer</p>
    
    <p>I edit again:
    Forgive, forget to say that my purpose is to create the certificate for an application in which you can make the registration to Facebook and tried the methods that my colleagues kindly offered, but it did not work, thanks to the new facebook policy.
    If you have another idea, then my domain would be michaelgram.test
    thank you and forgive the inconvenience, for not doing well the question.</p>
