How to Enable Developer Mode in Magento 2

The Developer mode in Magento is used when you want to customize your Magento 2 or add a new extension to the store. Magento 2 offers three different modes of use to its user admin: Default Mode, Developer Mode, and Production Mode.

The admin can apply and use different modes for their Magento stores depending on specific needs and circumstances. In this post, you will get to learn how to Enable Developer Mode in Magento 2.

Following are the useful features available in Developer mode:

• Verbose and extensible logging
• Compilation of code automatically
• Improved debugging
• Display custom X-Magento-* HTTP request and response headers

Switching via SSH or CLI
One of the best ways to switch Magento 2 to developer mode is by using a special CLI command. Here are the steps that you need to take:

Switching via .htaccess
Some hosts do not allow SSH/CLI access except FTP. For example. If this happens to you, you can force Magento 2 to go into developer mode using a special environment variable.

Here are the steps you need to follow:

• Log in to the admin panel and go to the root of your store.
• Clean data of directories var/di and var/generation
• Open the .htaccess file and edit it.
• Add the following line (usually at the beginning):
  SetEnv MAGE_MODE developer

This will force Magento 2 to run in Developer Mode.
