Add or update components | Magento 2 Developer Documentation

A contributing developer updates components by specifying components and their versions in Magento’s composer.json.

To update components if you’re not a contributing developer, see Updating the Magento application and components.

You can either add a require section to composer.json or you can use the composer require command as follows:

Log in to the Magento server, or switch to, the Magento file system owner.
Change to the directory to which you cloned the Magento application. For example,
```
1
cd /var/www/magento2
```

You have the following options:

Command usage:

composer show --all <vendor>/<name>

For example,

composer show --all example/module

Command usage:

composer require <vendor>/<name>:<version>

For example:

composer require example/module:1.0.0

Wait while Composer updates dependencies and installs the component.

Open composer.json in a text editor.

Add a require section like the following:

"require": {
  "<vendor>/<name>": "<version>",
  "<vendor>/<name>": "<version>"
}

Save your changes to composer.json, exit the text editor, and enter composer update
