Instantiate
The main purpose of this library is to be inherited by other libraries to create custom prompt types. However, the main export is a function that can be instantiated to run basic "input" prompts, if you want to see how everything works, run examples, tests, etc.
var Prompt = require('prompt-base');
var prompt = new Prompt({
name: 'first',
message: 'What is your name?'
});
// callback
prompt.ask(function(answer) {
console.log(answer);
//=> 'Jon'
});
// promise
prompt.run()
.then(function(answers) {
console.log(answers);
//=> {first: 'Jon'}
});
Inherit
var Prompt = require('prompt-base');
function CustomPrompt(/*question, answers, rl*/) {
Prompt.apply(this, arguments);
}
util.inherits(CustomPrompt, Prompt);
