Arguments

<name> - Required name of the model to create as an argument to the command. If provided, the tool will use that as the default when it prompts for the name.

Interactive Prompts

The tool will prompt you for:

• Name of the model. (modelName) If the name had been supplied from the command line, the prompt is skipped and the datasource is built with the name from the command-line argument.

The tool will next recursively prompt you for the model’s properties until a blank one is entered. Properties will be prompted for as follows:

• Name of the property. To add a property, enter a name here. To end the property prompt loop, leave this blank and press enter.
• Property type. Select the type for the property from the following options: string, number, boolean, object, array, date, buffer, geopoint, any.
• Is ID Field. Defaults to no. If the property is the ID for the Model, enter Y or yes. This will only be prompted until a property is marked as the id for the Model.
• Required. Defaults to no. If the property is required, enter Y or yes.
• Default value. Set a default value for the property if one isn’t supplied. Leave blank otherwise.

Output

Once all the prompts have been answered, the CLI will do the following:

• Create a Model class as follows: /src/models/${modelName}.model.ts
• Update /src/models/index.ts to export the newly created Model class.
