Using the Symfony Console Component To Improve Development & Deployment

What is the Symfony Console Component?

The Console component allows you to create command-line commands. Your console commands can be used for any recurring task, such as cronjobs, imports, or other batch jobs.

Please visit the official documentation page for more detailed information about this Symfony component.

How do I use the Symfony Console Component?

You can use the Symfony Console Component in either Windows Command Prompt (CMD) or Linux  Command Line Interface (CLI), the commands will work the same for both operating systems.

You will need to make sure PHP is in your PATH variable on Windows first.

Example Console Command

php app/console command:action --argumentName=argumentValue ...

Clearing the Production Cache

If for example you wanted to clear and warmup the cache for the production environment, you would execute the following commands:

php app/console cache:clear --env=prod
php app/console cache:warmup --env=prod

Now you should have your cache cleared and rebuilt ready to show any updates if you received no errors.

Make sure you do your database migrations before you clear your cache, as this will cause errors on the frontend of your site if you have schema changes.

Hopefully you are using database migrations for your project… you are using them right? I thought so…

Dumping Your Assetic Files

If you use the Assetic bundle in your projects, here is an example of how you would regenerate the assetic cache after making changes during development:

php app/console assetic:dump

That’s all you need to do to update your cached files.

I will add some more examples of the Symfony Console usage to future posts.
