Magento is a popular open-source eCommerce platform, which has a lot of extensions to add to its basic functionality.  It has a method for installing extensions in its control panel, but in my experience, it hasn’t been very reliable.  So, I usually just install extensions from the shell.  And, this is my quick cheat sheet on how you can install an extension in the shell.

1. cd into your Magento directory
2. Get the component name for composer, in the Magento marketplace it will be located under “My Profile > My Purchases”
3. composer require component/name
4. run “bin/magento module:status” to get the module’s name, it’ll be under “List of disabled modules:”
5. bin/magento module:enable ModuleName
6. bin/magento setup:upgrade
7. bin/magento setup:di:compile
8. bin/magento cache:clean
9. php bin/magento setup:static-content:deploy -f
10. There’s a known issue with Magento that it often won’t generate a “js-translation.json” file and that will break its back-end, but you can simply create one with empty JSON to fix the issue
11. nano pub/static/adminhtml/Magento/backend/en_US/js-translation.json
12. []

And you’re done!  If everything went off without a hitch you should see that extension working in your Magento control panel.
