How to make redirects for every rewrite?

Question

Apache HTTP Server

I have a lot of rewrites in htaccess, how can I make it so that each one has a redirect to a link with a slash at the end, if there is no slash at the end of the link?
Example:

RewriteRule ^([0-9]+)/$ /index.php?page=$1 
RewriteRule ^news/$ /index.php?mode=news
RewriteRule ^articles/$ /index.php?mode=articles
RewriteRule ^posts/feedback/$ /index.php?mode=posts

Is it really necessary to write something like this before each?

RewriteRule ^([0-9]+)$ /$1/
RewriteRule ^([0-9]+)/$ /index.php?page=$1
RewriteRule ^news$ /news/
RewriteRule ^news/$ /index.php?mode=news
RewriteRule ^articles$ /articles/
RewriteRule ^articles/$ /index.php?mode=articles
RewriteRule ^posts/feedback$ /posts/feedback/
RewriteRule ^posts/feedback/$ /index.php?mode=posts

Answer 1

RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_URI} !(.*)/$
RewriteRule ^(.*[^/])$ $1/ [L,R=301]

Well, then your rewrites:

RewriteRule news/$ /tmp/
RewriteRule forum/$ /tmp/
