Optimal development environment

A typical software development flow is as follows:

Local dev machine > QA/integration server > Preview server (optional) > Production server

Whether you are writing a new extension or contributing to the code base, the first step for any developer is setting up a development environment. This article will guide you in setting up and optimizing your local development machine.

Local development machine#

Your local development machine is where you develop and deploy your code to test it against a running Adobe Commerce or Magento Open Source application. Its configuration should be as close to a production server as possible.

In your development machine, make sure you are running the Adobe Commerce or Magento Open Source application in developer mode. You can enable this mode with the command bin/magento deploy:mode:set developer.

Installation#

The following is a list of the different ways you can install Adobe Commerce or Magento Open Source locally:

  • Manual installation: If you are developing on a local machine that meets the system requirements, you can follow the same steps for installing on a production server.

  • Virtual Machine (VM) installation: Installing Adobe Commerce and Magento Open Source in a virtual environment allows you to run it without the need to install a local LAMP stack.

    You can use a VM tool, such as VirtualBox, together with a virtual environment tool, such as Vagrant or Docker, to create reusable and shareable instances for development.

    A search for "magento developer box" in GitHub provides a list of unofficial virtual machines configured for development.

Optimal configuration#

The following is a list of optimizations you can make on your local development machine

  • We recommend installing and using the latest supported version of PHP 7 to increase performance.
  • Replace your MySQL database with Percona.
  • Make sure you install and enable PHP OPcache.
  • Xdebug is off by default. Enable this feature only when you need it because it requires a lot of memory and degrades performance. The xdebug.max_nesting_level configuration needs to be set to 200 or greater for Magento. You can increase the memory available to PHP to get an increase in performance with Xdebug on.
  • If you need sample data, you can install it using composer or by cloning repositories.
  • To speed up frontend development, turn off merging of CSS and JavaScript.
  • Make sure caching is turned on (this is the default behavior). Generally, only page cache and block cache should be turned off for development and turned back on when testing.
  • Opcache timestamp validation should always be on for development. Development is impossible with opcache on and revalidation off because any PHP modification would require a cache reset.
