12 Amazing Features of Magento 2


Category: Magento2

1 Backup / Rollback System in Magento 2

Magento 2's command line tool has some handy commands. These commands can be added to cron system to take automated backups. Rollback is another interesting command, it will place the site in the maintenance mode, restores the DB, files and media, and then enables the site. setup:backup Takes backup of Magento Application code base, media and database setup:rollback Rolls back Magento Application codebase, media and database info:backups:list Prints list of available backup files In addition to the above Schogini.biz has a handy module that can further augment the backup/rollback system. schogini schogini:cloudbackup Backup code, media and DB to Amazon S3 Cloud schogini:cloudrollback Rollbacks code, media and DB from Amazon S3 Cloud

2 Upgrading in Magento 2

Introduction of the PHP based dependency management using "composer" makes life easy. Composer to ensures the all components maintain their expected versions. With a single command, "composer update" all core and third party modules get updated.

3 Maintenance Mode and Restricting IP Addresses

The flag is relocated inside the var folder, in addition it, we can add the IPs to be allowed in a file var/.maintenance.ip Manual creation of the flag file and the IP file not needed, instead we can use the bin/magento command line tool. maintenance maintenance:allow-ips Sets maintenance mode exempt IPs maintenance:disable Disables maintenance mode maintenance:enable Enables maintenance mode maintenance:status Displays maintenance mode status

4 Three Modes in Magento 2 Developer, Production and Default

Developer Mode

This module is useful during the development phase where static file creation is done to save speed of iteration, uncaught exceptions are shown on the browser, error handler exceptions are not logged and very detailed error reporting in var/report.

Production Mode

Live shop should be in this mode where, maximum performance abd security are assured. In this mode exceptions are not shown to the user but only saved to the logs. Static files are not created for any changes made thus the docroot folder can be in read-only mode!

Default Mode

This mode is not needed! Neither good for production nor development.

5 Module Installation and Management

Installing of new modules is much easier in Magento 2. Add the modules version and repository details to the composer.json and running the install command will save the module. Once this is done we can run the bin/magento CLI tool to install the module. module module:disable Disables specified modules module:enable Enables specified modules module:status Displays status of modules module:uninstall Uninstalls modules installed by composer

6 PSR Compliance

PSR which stands for PHP Standard Recommendation. In this currently there are three standards. PSR-0 which is for compliance in the auto-loader interoperability. PSR-1 for a basic coding standard. * Only use the <?php and <?= tags. Only use UTF-8 without BOM for PHP code. * Separate side-effects (generate output, access a database etc.) and declarations. * Enforce PSR-0. * Class names must be defined in StudlyCaps. * Class constants must be defined in upper case with underscore separators. * Method names must be defined in camelCase.

PSR-2 is for the logger system viz: debug, info, notice, warning, error, critical, alert and emergency.

7 Performance

*Improved indexers, Magento 2 performance toolkit, Varnish caching integration, and Full page caching are all aimed to provide better performance and scalability

8 Magento 2 Admin Backend UI

A more intuitive admin backed reduces the learning curve and saves speed in finding required task.

9 Theme Developer's Delight : Blank Theme

Clean slate! A blank theme without no customization lets developers start creating new themes adding the required features one at a time. This not only enhanced the speed of theme development, but also reduces the learning curve. We should see more and more theme developers doing Magento 2 themes.

10 Migration Tool

Magento 2 comes with a Migration Tool that helps us to migrate from Magento 1.9.X.X to Magento 2 relatively easy. Using this tool one can migrate EAV, Attributes, Log, Shop Settings, Customers, Orders, Catalogs and Categories. Basically Magento 2 makes migration of data and settings easy.

11 Scalability

Modular architecture of Magento 2 lets us to breakdown the subsystems and hosting on different servers optimized for specific usage/load types. Catalog, Shipping, Sales, Checkot and Payment sub-systems can be separately optimized for increased performance, scalability and security.

12 Last but not the least: The Magento 2 Testing Framework

These are sections in the testing framework for integration, units, static environments, functional areas, and performance. This can reduce the bug fix iterations while making testing relatively easier.
