This guide has everything you need to know about Magento 2 Modes.
In this guide you’ll learn:New Magento users are often unaware that Magento can switch between 3 different modes which optimizes its performance based on the tasks they are going to perform. We're going to discuss the difference between Magento 2 modes, what they are used for, and how to switch between them.
Three Magento 2 modes of operation are:Where {mode} displays the Current Mode. It can be either Developer or Production.
Where {mode} represents the mode, you want to change to developer or production mode.
This is the ideal mode for developing your online store. All the settings and capabilities are set to suit the development work. In Magento 2 developer mode, the majority of error messages are displayed directly on the web page, so you are immediately aware of the issue or cause without shifting to error logs. Developer mode is the slowest of the 3 modes because of the lack of caching functions.
After running the above command, it will display the Enabled Developer Mode message.
When in developer mode, you may get a 404 error for scripts and CSS preventing CSS to load. This is because Magento 2 tries to create symlinks for some static resources. You can do the following to avoid or fix this error.
Production mode is built for speed and optimization and is ideal if you are making your store live. In this mode, all page content is cached to decrease page load time and increase the overall system performance. Magento 2 production mode is also the most secure and the file structure is not vulnerable unlike the above two modes. Additionally, some settings can be disabled from the backend to minimize the risk of breaking or misusing something. Production mode is the hardest to debug issues because no error message is sent to the web browser.
You will see the message Enabled Production Mode. Now, your store is running in the Production mode.
Quite obvious, the Magento 2 default mode operates when no other mode is specified. It’s a mix of both developer and production mode where it does not have the debugging capability of the developer mode and the speed of the production mode. Therefore, default mode serves no real purpose other than allowing you to quickly become familiar with Magento and load the store online. This is not the mode if you are doing development work because debugging issues take longer due to shifting between the different error log files.
Default mode also does not have the complete cashing potential unlike production mode because files are still generated on the fly.
You will see the message Enabled Default Mode.
In this article, we've briefly explained the Magento 2 modes. Now you can easily set default, developer, & production mode in your website.
The above commands works for all Magento versions (2.1.x, 2.2.x, 2.3.x, 2.4.x)
