I'm attempting to use the node.js inquirer package to run a simple flashcard generator. I'm having trouble getting the syntax to return the checkbox the user clicked. So, once the user makes a choice, I'd like to be able to log the result of that choice. Currently this console.log() returns "undefined".
Any help appreciated!
inquirer.prompt ([
{
type: "checkbox",
name: "typeOfCard",
message: "Select an action.",
choices: [
{
name: "Create a Basic Card"
},
{
name: "Create a Cloze Card"
},
{
name: "Run the flashcards!"
}
]
}
]).then(function(answers){
console.log(answers.typeOfCard[0])
});
const inquirer = require('inquirer');
inquirer.prompt ([
{
type: "checkbox",
name: "typeOfCard",
message: "Select an action.",
choices: [
"Create a Basic Card",
"Create a Cloze Card",
"Run the flashcards!"
]
}
]).then(function(answers){
console.log(answers.typeOfCard);
});
choices should just be an array of strings. You will then be returned an array containing the selected items, ex:
[ 'Create a Cloze Card', 'Run the flashcards!' ]
Hope that helps!
const inquirer = require("inquirer");
console.clear();
const main = async() => {
const readCardChoise = () => {
const read = new Promise((resolve, reject) => {
inquirer.prompt ([
{
type: "checkbox",
name: "typeOfCard",
message: "Select an action.",
choices: [
{
name: "Create a Basic Card"
},
{
name: "Create a Cloze Card"
},
{
name: "Run the flashcards!"
}
],
validate(answer) {
if (answer.length < 1) {
return 'You must choose at least one card.';
}
return true;
},
}])
.then((answers) => {
resolve(answers.typeOfCard);
});
});
return read;
}
const cadSelect = await readCardChoise();
console.log(cadSelect)
}
main();

I’m working on an application that sets a series of questions to generate an employee profile. As it is intended to be recursive, the user will be asked at the beginning and the end of the prompt to exit and terminate the enquire.
const employeeQuestions = [
// Role of employee
{
type: 'rawlist',
name: 'role',
message: 'What is the role of the employee?',
choices: [
'Engineer',
'Intern',
new inquirer.Separator(),
'Finish building the team', <=== THIS IS THE ANSWER THAT SHOULD TERMINATE THE PROMPT
],
default: 3,
},
// Employee questions
{
type: 'input',
name: `employee_name`,
message: answer => `Enter name of the ${answer.role}`,
},
{
type: 'number',
name: `employee_id`,
message: answer => `Enter ${answer.role} ID`,
validate(answer) {
const valid = !isNaN(parseFloat(answer));
return valid || 'Please enter a number';
},
filter: Number,
},
{
type: 'input',
name: `employee_email`,
message: answer => `Enter ${answer.role} Email address`,
},
// Engineer questions
{
when(answer) {
return answer.role === 'Engineer';
},
type: 'input',
name: `engineer_github`,
message: 'Enter GitHub username',
},
// Intern questions
{
when(answer) {
return answer.role === 'Intern';
},
type: 'input',
name: `intern_school`,
message: 'Enter intern school',
},
// add more employees
{
type: 'confirm',
name: `add_more`,
message: 'Do you want to add another employee?', <=== THIS IS THE QUESTION THAT SHOULD TERMINATE THE PROMPT
default: true,
},
];
// # Functions
// * Inquires all over if add_more = true
function inquireAgain() {
inquirer.prompt(employeeQuestions).then(answers => {
employeesInfo.push(answers);
if (answers.add_more) {
inquireAgain();
} else {
console.log(JSON.stringify(employeesInfo, null, ' '));
}
});
}
// * Initialize the inquirer prompts
async function init() {
const inquireManager = await inquirer.prompt(managerQuestions);
employeesInfo.push(inquireManager);
inquireAgain();
}
// # Initialisation
init();
this is the closest thing I found related to terminate the prompt, but is not working for me, Thanks in advance.
I want to specify choices for an option for my command in Discord.js. How do I do that?
The command:
module.exports = {
name: 'gifsearch',
description: 'Returns a gif based on your search term.',
options: [{
name: 'type',
type: 'STRING',
description: 'Whether to search for gifs or stickers.',
choices: //***this is the area where I have a question***
required: true
},
{
name: 'search_term',
type: 'STRING',
description: 'The search term to use when searching for gifs.',
required: true,
}],
async execute(interaction) {
let searchTerm = interaction.options.getString('search_term')
const res = fetch(`https://api.giphy.com/v1/gifs/search?q=${searchTerm}&api_key=${process.env.giphyAPIkey}&limit=1&rating=g`)
.then((res) => res.json())
.then((json) => {
if (json.data.length <= 0) return interaction.reply({ content: `No gifs found!` })
interaction.reply({content: `${json.data[0].url}`})
})
},
};
I have read the discord.js documentation/guide and I know about the .addChoice() method, but it doesn't look like that will be compatible with my bot's current code.
The discord.js api describes this as ApplicationCommandOptionChoices.
So you basically just insert an array of this in your choices.
module.exports = {
...
choices: [
{
name: "name to display",
value: "the actual value"
},
{
name: "another option",
value: "the other value"
}
]
...
};
I have this data
var data = [
{
title: "App development summary",
category: [],
},
{
title: "to experiment 2",
category: [],
},
{
title: "Some of these books I have read",
category: [
{
_id: "5f7c99faab20d14196f2062e",
name: "books",
},
{
_id: "5f7c99faab20d14196f2062f",
name: "to read",
},
],
},
{
title: "Quora users and snippets",
category: [
{
_id: "5f7c99feab20d14196f20631",
name: "quora",
},
],
},
{
title: "Politics to research",
category: [
{
_id: "5f7c9a02ab20d14196f20633",
name: "politics",
},
],
},
];
Say I want to get all the entries with the category of books. I tried doing this:
var bookCat = data.map(note => {
return note.category.map(cat => {
if(cat.name === "books" ) return note
})
})
But the result comes back with some empty and undefined arrays.
I was able to filter the empty arrays (at one point) but not the undefined
Edit
In plain English "if the object ha category.name "books", give me the title"
Filter by whether the array's category contains at least one name which is books:
var data=[{title:"App development summary",category:[]},{title:"to experiment 2",category:[]},{title:"Some of these books I have read",category:[{_id:"5f7c99faab20d14196f2062e",name:"books"},{_id:"5f7c99faab20d14196f2062f",name:"to read"}]},{title:"Quora users and snippets",category:[{_id:"5f7c99feab20d14196f20631",name:"quora"}]},{title:"Politics to research",category:[{_id:"5f7c9a02ab20d14196f20633",name:"politics"}]}];
const output = data
.filter(item => item.category.some(
({ name }) => name === 'books'
));
console.log(output);
If there's guaranteed to be only a single matching object, use .find instead:
var data=[{title:"App development summary",category:[]},{title:"to experiment 2",category:[]},{title:"Some of these books I have read",category:[{_id:"5f7c99faab20d14196f2062e",name:"books"},{_id:"5f7c99faab20d14196f2062f",name:"to read"}]},{title:"Quora users and snippets",category:[{_id:"5f7c99feab20d14196f20631",name:"quora"}]},{title:"Politics to research",category:[{_id:"5f7c9a02ab20d14196f20633",name:"politics"}]}];
const output = data
.find(item => item.category.some(
({ name }) => name === 'books'
));
console.log(output);
Apologies if this has been answered before, I have checked other answers and can't work it out from those.
I have a set of information that I would like placed into an array named "teamDetails". Here is the relevant /post item from server.js:
app.post('/create', (req, res) => {
console.log('Post command received');
console.log(req.body);
console.log(req.body.data.teamDetails[0]);
//We need to push the variable below, 'teamDetails', as an object into an array of the same name
var teamDetailsObj = {
// Modified for Postman
"teamName": req.body.data.teamDetails[0].teamName,
"teamNameShort": req.body.data.teamDetails[0].teamNameShort,
"teamfounded": req.body.data.teamDetails[0].teamFounded,
"teamHome": req.body.data.teamDetails[0].teamHome
};
console.log(teamDetails);
var newTeam = new Team({
"data.added": new Date(),
"data.entry": req.body.data.entry
});
newTeam.save().then((doc) => {
console.log("This is newTeam.data: " + newTeam.data);
console.log("This is teamDetailsObj: " + teamDetailsObj);
newTeam.data.teamDetails.push(teamDetailsObj);
var teamId = doc.id;
res.render('success.hbs', {teamId});
console.log("Team Added - " + teamId);
}, (e) => {
res.status(400).send(e);
});
});
Here is my team.js model:
var mongoose = require('mongoose');
var ObjectID = mongoose.Schema.Types.ObjectId;
var Mixed = mongoose.Schema.Types.Mixed;
var Schema = mongoose.Schema;
var Team = mongoose.model('Team', {
data: {
entry: {
type: String,
default: "USER.INPUT"
},
added: {
type: Date,
default: Date.Now
},
teamDetails: [
{
teamName: {
type: String,
trim: true,
required: true,
default: "First Team"
},
teamNameShort: {
type: String,
trim: true,
uppercase: true,
maxlength: 3,
required: true
},
teamFounded: {
type: Number,
maxlength: 4
},
teamHomeCity: {
type: String
}
}
]
}
});
module.exports = {Team};
Lastly, the sample data I'm trying to inject via Postman:
{
"data": {
"entry": "Postman.Entry",
"teamDetails": [
{
"teamName": "Test Teamname",
"teamNameShort": "TTN",
"teamFounded": "1986",
"teamHome": "London",
"players": [
{
"player1Name": "Test Player 1",
"player1Position": "Forward",
"player1Nationality": "GBR"
},
{
"player2Name": "Test Player 2",
"player2Position": "Defender",
"player2Nationality": "UKR"
},
{
"player3Name": "Test Player 3",
"player3Position": "Goaltender",
"player3Nationality": "IRL",
"captain": true
}
],
"coachingStaff": {
"headCoach": "Derp McHerpson",
"teamManager": "Plarp McFlarplarp"
}
}
]
}
}
(Disregard the players section, it's another kettle of fish)
As a result of using my code above, the resulting entry for teamDetails is just an empty array. I just can't get my code to push the teamDetailsObj into it.
Any help anyone can provide is appreciated.
It looks like you add teamObjDetails AFTER saving it with newTeam.save().then( ... )
I'm not a lot familiar with Mongoose but I don't see how could the team details could be present if not added before saving.
Let me know if it changes something !

I am making a GraphQL API where I would be able to retrieve a car object by its id or retrieve all the cars when no parameter is provided.
Using the code below, I am successfully able to retrieve a single car object by supplying id as a parameter.
However, in the case where I would expect an array of objects i.e. when I supply no parameter at all, I get no result on GraphiQL.
schema.js
let cars = [
{ name: "Honda", id: "1" },
{ name: "Toyota", id: "2" },
{ name: "BMW", id: "3" }
];
const CarType = new GraphQLObjectType({
name: "Car",
fields: () => ({
id: { type: GraphQLString },
name: { type: GraphQLString }
})
});
const RootQuery = new GraphQLObjectType({
name: "RootQueryType",
fields: {
cars: {
type: CarType,
args: {
id: { type: GraphQLString }
},
resolve(parent, args) {
if (args.id) {
console.log(cars.find(car => car.id == args.id));
return cars.find(car => car.id == args.id);
}
console.log(cars);
//***Problem Here***
return cars;
}
}
}
});
Test queries and their respective results:
Query 1
{
cars(id:"1"){
name
}
}
Query 1 Response (Success)
{
"data": {
"cars": {
"name": "Honda"
}
}
}
Query 2
{
cars{
name
}
}
Query 2 Response (Fail)
{
"data": {
"cars": {
"name": null
}
}
}
Any help would be much appreciated.
A Car and a List of Cars are effectively two separate types. A field cannot resolve to a single Car object one time, and an array of Car object another.
Your query is returning null for the name because you told it the cars field would resolve to a single object, but it resolved to an array instead. As a result, it's looking for a property called name on the array object and since one doesn't exist, it's returning null.
You can handle this in a couple of different ways. To keep things to one query, you can use filter instead of find and change the type of your query to a List.
cars: {
type: new GraphQLList(CarType), // note the change here
args: {
id: {
type: GraphQLString
},
},
resolve: (parent, args) => {
if (args.id) {
return cars.filter(car => car.id === args.id);
}
return cars;
}
}
Alternatively, you could split this into two separate queries:
cars: {
type: new GraphQLList(CarType),
resolve: (parent, args) => cars,
},
car: {
type: CarType,
args: {
id: {
// example of using GraphQLNonNull to make the id required
type: new GraphQLNonNull(GraphQLString)
},
},
resolve: (parent, args) => cars.find(car => car.id === args.id),
}
Check the docs for more examples and options.
