What are the different modes in Magento 2?

1. Default Mode

As the name suggests, the default mode is when no other mode is specified. In the default mode, you can deploy the Magento application on a single server without any changes in the settings. When you first launch a Magento 2 site, it automatically starts in the default mode. This mode is a combination of developer and production mode.

• The user never sees errors. Errors are logged to the file reports on the server.

• Static view files are materialized first, then cached. It's not ideal for production.

• Symlinks to static view files should be published to pub/static.

2. Developer Mode

It is specifically designed for developers. It handles all development tasks by automatically compiling code and providing advanced logging and debugging features. While slower on the front end and Magento admin, it's great for customizing or extending Magento 2's default features.

• Static view files are stored in the Magento pub/static directory and are not cached.

• Errors and exceptions are shown in the browser.

• System logging is set to verbose.

• Exceptions are displayed in the error handler instead of being logged, making it easier to identify and troubleshoot errors directly in the browser.

• If an event subscriber cannot be invoked, an exception is thrown, leading to faster debugging of extension conflicts.

3. Production Mode

The live and operational Magento 2 sites are in production mode. This mode ensures that the website is optimized for performance, stability, and security.

It allows for efficient handling of customer requests, smooth transaction processing, and reliable delivery of content. For the best customer experience, switch your store to the production environment.

The production mode utilizes full-page caching and a complete pub folder for seamless and efficient store functioning. Debugging in production is challenging because errors are logged in the file system and not displayed to the user. Additionally, merged CSS and Javascript do not function in this mode.

• The production mode is the most secure for security.

• It doesn't create a symlink for the pub/static folder.

• If an unauthenticated user accesses pub/static and tries to change the data, they will only modify duplicate file versions.

• These changes will be overwritten during the next static deployment.
