Prompt Types

Demonstrates how to use different types of prompts such as 'input' for text input and 'list' for selecting from a list of options.

import inquirer from 'inquirer';

async function askQuestion() {
  const answers = await inquirer.prompt([
    {
      type: 'input',
      name: 'name',
      message: 'What's your name?',
    },
    {
      type: 'list',
      name: 'choice',
      message: 'Pick a choice:',
      choices: ['Choice A', 'Choice B'],
    }
  ]);

  console.log(answers);
}

askQuestion();

Validation

Shows how to validate user input to ensure it meets certain criteria, in this case, checking if the input is a number.

import inquirer from 'inquirer';

inquirer.prompt([
  {
    type: 'input',
    name: 'age',
    message: 'Enter your age:',
    validate: function(value) {
      var valid = !isNaN(parseFloat(value));
      return valid || 'Please enter a number';
    },
    filter: Number,
  }
]).then(answers => {
  console.log(`Your age is ${answers.age}`);
});

Conditional Questions

Illustrates how to ask questions conditionally based on previous answers using the 'when' property.

import inquirer from 'inquirer';

inquirer.prompt([
  {
    type: 'confirm',
    name: 'toBeAsked',
    message: 'Do you want to answer more questions?',
  },
  {
    type: 'input',
    name: 'moreInfo',
    message: 'Tell me more:',
    when: function(answers) {
      return answers.toBeAsked;
    }
  }
]).then(answers => {
  console.log(answers);
});
