Also esbs is to use it as a library. In this case, just include it in your Node.js project by adding a line for "esbs" in your pacakge.json dependencies. For more information about your package.json file, you should check out the npm documentation by running npm help json.

Alternatively, you can quickly install Filepath for use in a project by running

npm install esbs

which will install esbs in your node_modules/ folder.
