jsDelivr operates thanks to our main sponsors:

A free API for all NPM
and ESM needs

The jsDelivr API allows you to get details about NPM packages such as their versions and files. We intelligently guess the correct entrypoints and provide the CDN URLs with their hashes.

Additionally you can get detailed download statistics for each project, version, and file.

    },
    " css ": {
      " file ": " / dist / css / bootstrap .min .css ",
      " guessed ":  false
    }
  }
}
