Set the operation mode

To improve security and ease-of-use, we added a command that switches application modes from developer to production and vice versa.

Production mode 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, we clear the contents of following directories:

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

Exceptions:

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

Display the current mode

The easiest way to do that is to run this command as the file system owner. If you have shared hosting, this is the user your provider gives you to log in to the server. If you have a private server, it is typically a local user account on the Commerce server.

Command usage:

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 developer or production

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

Examples follow.

Change to production mode

bin/magento deploy:mode:set production

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:

1. If you are 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/*
   

2. Set the mode:

   bin/magento deploy:mode:set developer
   

   The following message displays:

   Enabled developer mode.
   

Change to default mode

bin/magento deploy:mode:set default

The following message displays:

Enabled default mode.

If you have not added <Commerce-install-directory>/bin to your system PATH, then you can expect an error when running the command by itself.
