How to Change Magento 2 mode (Default, Production, Development)

Display the Current Mode

The easiest way to do that is to run this command as the Magento 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’s typically a local user account on the Magento server.

 bin/magento deploy:mode:show

You then get a message letting you the current mode

 Current application mode: developer.

Magento 2 Change Modes

Below is the basic syntax for changing the Magento 2 mode

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


{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.

With that being stated, lets show an example of changing your site to developer and production

Change to production mode

 bin/magento deploy:mode:set production

You then see status as it switches the site over to production, example:

 Enabled maintenance mode

     ... more ...
 Compilation complete
 Disabled maintenance mode
 Enabled production mode.

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 var/generation and var/di directories:

 rm -rf <your Magento install dir>/var/di/* <your Magento install dir>/var/generation/*

Set the mode:

 bin/magento deploy:mode:set developer

The following message displays:

 Switched to developer mode.

Special Note:

Once you switch from default mode you can not switch back to it, it has be production or developer
