Why does composer not find npm package?

Question

Yii

A strange problem has arisen.
In a Yii2 project, you need to connect some npm-based assets .
To do this, the composer has a plugin "fxp/composer-asset-plugin", which is actually by default.
Composer.json also has path settings:

"asset-installer-paths": {
            "npm-asset-library": "vendor/npm",
            "bower-asset-library": "vendor/bower"
        }

After that I try to make require
composer require "npm-asset/atob"
As a result this package is not found at all. Although, if you do npm install it, everything is fine. But the problem is that this needs to be done via composer.
