Code that extends or customizes Adobe Commerce and Magento Open Source behavior is called an extension. You can optionally package and distribute extensions on the Commerce Marketplace or another extension distribution system.

Extensions include:

  • Modules (extend Adobe Commerce and Magento Open Source capabilities)
  • Themes (change the look and feel of your storefront and Admin)
  • Language packages (localize the storefront and Admin)
TIP
This topic explains how to use the command line to install extensions you purchase from the Commerce Marketplace. You can use the same procedure to install any extension; all you need is the extension’s Composer name and version. To find it, open the extension’s composer.json file and note the values for "name" and "version".

Before installation, you may want to:

  1. Back up your database.

  2. Enable maintenance mode:

    code language-bash 
    bin/magento maintenance:enable

To install an extension, you must:

  1. Get an extension from the Commerce Marketplace or another extension developer.

  2. If you install an extension from the Commerce Marketplace, make sure that the repo.magento.com repository exists in your composer.json file:

    code language-bash 
    "repositories": [
    {
        "type": "composer",
        "url": "https://repo.magento.com/"
    }
]

  3. Get the extension’s Composer name and version.

  4. Update the composer.json file in your project with the name and version of the extension.

  5. Verify that the extension installed properly.

  6. Enable and configure the extension.

Get the extension Composer name and version

If you already know the extension’s Composer name and version, skip this step and continue with Update your composer.json file.

To get the extension’s Composer name and version from the Commerce Marketplace:

  1. Log in to Commerce Marketplace with the username and password you used to purchase the extension.

  2. In the upper-right corner, click Your name > My Profile.

    Access your Marketplace account

  3. Click My Purchases.

    Marketplace purchase history

  4. Find the extension that you want to install and click Technical Details.

    Technical details shows the extension's Composer name

TIP
Alternatively, you can find the Composer name and version of any extension (whether you purchased it on Commerce Marketplace or somewhere else) in the extension’s composer.json file.

Update your Composer file

Add the extension’s name and version to your composer.json file:

  1. Navigate to your project directory and update your composer.json file.

    code language-bash 
    composer require <component-name>:<version>

    For example,

    code language-bash 
    composer require j2t/module-payplug:2.0.2

  2. Enter your authentication keys. Your public key is your username; your private key is your password.

  3. Wait for Composer to finish updating your project dependencies and make sure that there aren’t any errors:

    code language-terminal 
    Updating dependencies (including require-dev)
Package operations: 1 install, 0 updates, 0 removals
  - Installing j2t/module-payplug (2.0.2): Downloading (100%)
Writing lock file
Generating autoload files

Verify the extension

To verify that the extension installed properly, run the following command:

bin/magento module:status J2t_Payplug

By default, the extension is probably disabled:

Module is disabled

The extension name is in the format <VendorName>_<ComponentName>; this is a different format from the Composer name. Use this format to enable the extension. If you are unsure of the extension name, run:

bin/magento module:status

And look for the extension under “List of disabled modules”.

Enable the extension

Some extensions don’t work properly unless you clear generated static view files first. Use the --clear-static-content option to clear static view files when you’re enabling an extension.

  1. Enable the extension and clear static view files:

    code language-bash 
    bin/magento module:enable J2t_Payplug --clear-static-content

    You should see the following output:

    code language-terminal 
    The following modules have been enabled:
- J2t_Payplug

To make sure that the enabled modules are properly registered, run 'setup:upgrade'.
Cache cleared successfully.
Generated classes cleared successfully. Please run the 'setup:di:compile' command to generate classes.
Generated static view files cleared successfully.

  2. Register the extension:

    code language-bash 
    bin/magento setup:upgrade

  3. Recompile your project: In Production mode, you may receive a message to “Please rerun Magento compile command”. The application does not prompt you to run the compile command in Developer mode.

    code language-bash 
    bin/magento setup:di:compile

  4. Verify that the extension is enabled:

    code language-bash 
    bin/magento module:status J2t_Payplug

    You should see output verifying that the extension is no longer disabled:

    code language-terminal 
    Module is enabled

  5. Clean the cache:

    code language-bash 
    bin/magento cache:clean

  6. Configure the extension in Admin as needed.

TIP
If you encounter errors when loading the storefront in a browser, use the following command to clear the cache: bin/magento cache:flush.

Upgrade an extension

To update or upgrade a module or extension:

  1. Download the updated file from Marketplace or another extension developer. Take note of the module name and version.

  2. Export the contents to your application root directory.

  3. If a Composer package exists for the module, run one of the following.

    Update per module name:

    code language-bash 
    composer update vendor/module-name

    Update per version:

    code language-bash 
    composer require vendor/module-name ^x.x.x

  4. Run the following commands to upgrade, deploy, and clean the cache.

    code language-bash 
    bin/magento setup:upgrade --keep-generated
    code language-bash 
    bin/magento setup:static-content:deploy
    code language-bash 
    bin/magento cache:clean
