A free API for all your
NPM and ESM needs

The jsDelivr API allows you to get details about NPM packages, such as their versions, tags, and files. By analyzing package metadata and its real usage, it can automatically suggest the correct entry point for each file type.

Additionally the API provides detailed download statistics for each project, version, and file, as well as network-wide usage statistics.
