// set the view folder to views
app.set('views', __dirname + '/template');
// set the view engine to pug
app.set('view engine', 'pug');

      res.send('There was an error sending the email');
    return res.send('Email has been sent!');

Git ignore file permission changes

Sometime you change the mode of files of your project.

Git chmod

sudo chmod -R 777 /var/www/project

But files are not modified in the repo. check the modified files in git status. so git show all these files are modified.

So you can remove these files from modified using this command.

git config core.fileMode false

       If false, the executable bit differences between the index and the
       working copy are ignored; useful on broken filesystems like FAT.
       See git-update-index(1). True by default.

git -c core.fileMode=false diff

And the --global flag will make it be the default behavior for the logged in user.

git config --global core.fileMode false

I hope this post will help you.
