Question

A question object is a hash containing question related values:

• type: <string> Type of the prompt.
• name: <string> The name to use when storing the answer in the answers hash. If the name contains periods, it will define a path in the answers hash.
• message: <string| (rootObject: object) => string > The question to print. If defined as a function, the first parameter will be the current inquirer session answers. Defaults to the value of name (followed by a colon).
• default: <string|number|boolean|array|function> Default value(s) to use if nothing is entered, or a function that returns the default value(s). If defined as a function, the first parameter will be the current inquirer session answers.
• choices: <array| (rootObject: object) => array > Choices array or a function returning a choices array. If defined as a function, the first parameter will be the current inquirer session answers. Array values can be simple numbers, strings, or objects containing a name (to display in list), a value (to save in the answers hash) and a short (to display after selection) properties. The choices array can also contain a Separator.
• validate: < (input: string, hash: object) => boolean > Receive the user input and answers hash. Should return true if the value is valid, and an error message (String) otherwise. If false is returned, a default error message is provided.
• filter: < input => string > Receive the user input and return the filtered value to be used inside the program. The value returned will be added to the Answers hash.
• transformer: < (input: string, hash: object, flags: object) => string > Receive the user input, answers hash and option flags, and return a transformed value to display to the user. The transformation only impacts what is shown while editing. It does not modify the answers hash.
• when: < hash => boolean > Receive the current user answers hash and should return true or false depending on whether or not this question should be asked. The value can also be a simple boolean.
• pageSize: <number> Change the number of lines that will be rendered when using list, rawList, expand or checkbox.
• prefix: <string> Change the default prefix message.

• suffix: <string> Change the default suffix message.
