The FaaS Command Line Interface (CLI) is an open-source command-line tool provided by LivePerson that enables developers to create, edit and process their functions on their local development machines, in their favorite IDE of their choice. That way it’s very easy to keep the source code under version control in any Source Control Management (SCM).

The CLI offers nearly all functionality from the platfrom (e.g. deploy, undeploy and invoke).

Besides that it offers many commands to support developers during the development of a function (e.g. pull, push and debug).

Get started

To start and get known to the usage of the CLI please visit npmjs.

SSO Support

Currently, the CLI login is restricted to the user login method. To use the login with an SSO enabled account you have to fetch the token and userId from the FaaS UI.

It is advisable to create a separate account for the CLI, because with each new login on a different page the token expires in the CLI (only one login per account is possible).

To get the token and the userId follow these steps:

  1. Open the FaaS UI and log in.
  2. Open the developer tools of your browser.
  3. Go to the 'Application' tab.
  4. Open the session storage with the key 'houston.'.
  5. Copy token and userId.
    • Token: 'glob'
    • UserId: 'config.userId'

  6. Run the login command as follows: lpf login --token <bearer> --accountId <accountId> --userId <userId>

Note: If you get a message that the token is not valid anymore, you have to perform step 1 - 6 again.
