What platforms can developers create applications with using the NPM SDK?

The NPM SDK allows developers to create applications that can be integrated with both Blade and the Liferay SDK, making option C the most suitable choice.

Blade is a specific command-line tool that helps developers build modules and applications for Liferay. It leverages the features of the Liferay platform to streamline development for Java-based applications. On the other hand, the Liferay SDK is a broader framework that provides libraries, tools, and resources for developing applications on the Liferay platform, including support for various configurations and deployment scenarios.

By choosing the NPM SDK, developers gain the flexibility to use both these tools in their work. This dual compatibility enhances their workflow and allows for a seamless integration of modern front-end technologies with Liferay’s robust back-end capabilities. Thus, understanding the interplay between Blade and the Liferay SDK in the context of the NPM SDK is crucial for efficient application development on the Liferay platform.
