 # @eik/node-client
 
-This is an Eik utility for servers running on Node. With it you can:
-
-- generate different URLs to assets on an Eik server depending on environment (development vs production).
-- get the import maps you have configured in `eik.json` from the Eik server, should you want to use them in the HTML response.
+This is a utility for getting assets and import maps from [Eik servers](https://github.com/eik-lib/service#readme) in Node web applications. For publishing and managing assets to an Eik server from Node scripts, see [`@eik/cli`](https://github.com/eik-lib/cli#readme).

+The most common use case for this module is linking to a file. When developing you typically want to use a local version of the file, then link to the published version on Eik when running in production.
+
+For that you use the [`file()` method](#filepathname), which returns an object `{ value, integrity }` where `value` is the link to the file.
 
-When developing you typically want to use a local version of the file, then link to the published version on Eik when running in production.
+When running in production the link will point to the file on Eik. When `development` is `true` the pathname is prefixed with the `base` option instead of pointing to Eik, so your app can use a local version.
