Switching modes in magento2

Switching modes in magento2

An overview
To improve security and ease-of-use, magento has built-in commands that switches magento modes from developer to production and vice versa. Production mode also has better performance because static view files are populated in the pub/static directory and because of code compilation.
When you change to developer or production mode, the contents of following directories are cleared:

-      var/cache
-      generated/metadata
-      generated/code
-      var/view_preprocessed
-      pub/static

NOTE : These paths are with respect to the magento2 installation directory(generally public_html).

Exceptions:

  • .htaccess files are not removed
  • pub/static contains a file that specifies the version of static content; this file is not removed

Changing modes

To display the current mode, switch to magento installation directory as magento2 file system owner and run the above command -
bin/magento deploy:mode:show
A message similar to the following displays:
Current application mode: {mode}. (Note: Environment variables may override this value.)
where, {mode} can be either default, developer, or production.

Change modes

Command usage:

 bin/magento deploy:mode:set {mode} [-s|--skip-compilation]

where,

  • {mode} is required; it can be either default, developer, or production

  • --skip-compilation is an optional parameter you can use to skip code compilation when you change to production mode.


Change to production mode
      bin/magento deploy:mode:set production
Messages similar to the following will display -

Change to developer mode
When you change from production to developer mode, you should clear 
generated classes and Object Manager entities like proxies to prevent 
unexpected errors. After doing so, you can change modes. Use the 
following steps:
If you’re changing from production mode to developer mode, delete the contents of the generated/code and generated/metadata directories:

rm -rf <magento_root>/generated/metadata/* <magento_root>/generated/code/*

Set the mode : bin/magento deploy:mode:set developer

The following message displays:
====================
Enabled developer mode.
====================

Change to default mode

Run the above command from magento2 installation directory as magento file system owner :
      bin/magento deploy:mode:set default

The following message displays:
==================
Enabled default mode.
