Change document root to subfolder in cpanel

Question

I have a React app created with Create React App. I need to sever the files from /build/. How to change to root to /build? I have already pushed the entire files ie src, public and this is with git. If I had known, id git only the build folder but that seems too late (deploybot, bitbucket etc).

Ive created a .htaccess file with

RewriteEngine on
RewriteCond %{HTTP_HOST} ^web.com/$ [NC,OR]
RewriteCond %{HTTP_HOST} ^www.web.com/$
RewriteCond %{REQUEST_URI} !build/
RewriteRule (.*) /build/$1 [L]

But nothing works when I got to /. All that I see are the build folder, src etc

Answer 1

You can use this rule:

RewriteEngine on

RewriteCond %{HTTP_HOST} ^(?:www\.)?web\.com$ [NC]
RewriteCond %{REQUEST_URI} !^/build/
RewriteRule (.*) /build/$1 [L]

In your condition:

RewriteCond %{HTTP_HOST} ^web.com/$ [NC,OR]

There is a trailing slash which is never part of HTTP_HOST variable and there is an an unescaped dot that may match any character.

You can also combine both conditions into one by making www. optional as in my answer.
