Autocomplete prompt for inquirer

npm install --save inquirer-autocomplete-prompt

This prompt is anonymous, meaning you can register this prompt with the type name you please:

inquirer.registerPrompt('autocomplete', require('inquirer-autocomplete-prompt'));
inquirer.prompt({
  type: 'autocomplete',
  ...
})

Change autocomplete to whatever you might prefer.

Note: allowed options written inside square brackets ([]) are optional. Others are required.

type, name, message, source[, pageSize, filter, when, suggestOnly, validate]

See inquirer readme for meaning of all except source and suggestOnly.

Source will be called with previous answers object and the current user input each time the user types, it must return a promise.

Source will be called once at at first before the user types anything with null as the value. If a new search is triggered by user input it maintains the correct order, meaning that if the first call completes after the second starts, the results of the first call are never displayed.

suggestOnly is default false. Setting it to true turns the input into a normal text input. Meaning that pressing enter selects whatever value you currently have. And pressing tab autocompletes the currently selected value in the list. This way you can accept manual input instead of forcing a selection from the list.

validate is only active when suggestOnly is set to true. It behaves like validate for the input prompt.

inquirer.registerPrompt('autocomplete', require('inquirer-autocomplete-prompt'));
inquirer.prompt([{
  type: 'autocomplete',
  name: 'from',
  message: 'Select a state to travel from',
  source: function(answersSoFar, input) {
    return myApi.searchStates(input);
  }
}]).then(function(answers) {
  //etc
});

See also example.js for a working example.

I recommend using this package with fuzzy if you want fuzzy search. Again, see the example for a demonstration of this.
