Install Command Line Interface (CLI)

Zet is a command line interface that helps developers build and package widgets in Zoho Creator. The Command Line Interface, or CLI, is used to send commands to a software program as lines of texts in order to interact with it. This interaction includes typing commands into the interface and receiving responses to them. This text-based interface has its basis in the Graphical User Interface (GUI) but provides a mechanism that is easier to use. Developers use CLIs to create applications, software, and operating systems.

Zoho Creator enables you to create and integrate a widget using CLI.

Prerequisites to install CLI

  • Use the following command to verify the installation:
    $ node -v
    $ npm -v

Start server

    $ zet run

    This will run the HTTP server in your local machine in port number 5000. The port should not be occupied with any other process before starting the server.

Validate and package the application

  1. Run the following command to validate your application:
    $ zet validate

    This will validate your app package and identify any violations. They should be corrected before updating the zip in the developer console.

  2. Run the following command to generate a zip of your application that can be uploaded:
    $ zet pack

    This will create a zip file of the application in the "dist" folder of your project directory. This zip file needs to be uploaded to the Zoho Creator.
