How to force all traffic to HTTPS using .htaccess

Probably the most common way to force traffic to https is by redirecting requests using .htaccess. The .htaccess is a simple text file simply called ‘.htaccess’ which contains additional settings passed to the web server to support some more complicated functionality. If you are using a script created by other people (including CMS like Wordpress), you can probably find a .htaccess file already in the htdocs folder of your website. If you don’t have a .htaccess file yet, you can create a file using the File Manager with the file name .htaccess. Using the File Manager is recommended, some systems (especially Windows) don’t work well with .htaccess files.

After you’ve found or created your .htaccess file, you can edit it in the File Manager or using any text editor (like Notepad). You need to add the following lines to the file:

RewriteEngine On
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteCond %{HTTPS} off

Running both Client & Backend server concurrently

Often we have to open 2 terminals, one for front-end and another for back-end while development, It's cumbersome to keep managing both the servers, if one server stops the other one keeps running for no reason.

We can make use of a cli-tool called concurrently available on npm. As the name implies it enables us to run multiple Instances of servers on one terminal and we can start and stop all the servers at same time with just one command.

Let's see how to set it up for our project.
