Methods

inquirer.prompt(questions) -> promise

Start conversation (inquiry session)

• questions (Array) containing Question Object
• returns a Promise

Objects

Question

A question object is a hash containing question related values:

• type: (String) Type of the prompt. Defaults: input - Possible values: input, confirm, list
• 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|Function) 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|Function) 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 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 (TODO): (Function) 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 (TODO): (Function) 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 (TODO): (Function) 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 (TODO): (Function, 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.

Answers

A key/value hash containing the client answers in each prompt.

• Key The name property of the question object
• Value (Depends on the prompt)
  • confirm: (Boolean)
  • input : User input (filtered if filter is defined) (String)
  • list : Selected choice value (or name if no value specified) (String)
