I have changed the protocol on my website to http instead of https.
The following is my code that serves the server.
const https = require('https');
const httpsOptions = {
    key : fs.readFileSync('example.key'),
    cert : fs.readFileSync('example.crt')
};
https.createServer(httpsOptions, app).listen(port, ()=>{
    console.log('server listening at 3000')
});
But now whenever I try to enter my locally run site https://localhost:3000, it shows security warning that the website is not safe anymore.
So I went to google docs https://developers.google.com/web/updates/2016/10/avoid-not-secure-warn to see how to remove the sign and it says 'create the entire website as https' but what I don't understand is all my sites are already https. To see all my views https must be used instead of http.
Is the above code not enough to make all the pages https? if it is, what else do I have to do so that I don't frighten my clients by showing warnings when they enter my site?
