在导入中使用 JavaScript NPM 包

Question

I am using the kahoot-api NPM module ( GitHub , NPM ) and it requires using JavaScript import. (edit, this is a Node.js package. I didn't know the difference between JS and Node.js at the time of writing this, this is why this question was created).

The documentation says to use the following JavaScript import script to import Session and Adapters :

import { Session, Adapters } from 'kahoot-api';

This throws an error saying that I need to use a relative reference.

Failed to resolve module specifier "kahoot-api". Relative references must start with either "/", "./", or "../".

My files and folders are structured as so:

• index.php
• node_modules
  • @omegaboot
    • kahoot-api

All of the NPM files for kahoot-api are inside of the kahoot-api folder.

I have modified my JavaScript code to use a relative reference, as shown below.

import { Session, Adapters } from './node_modules/@omegaboot/kahoot-api/';

No errors are thrown, however the two imported statements Session and Adapters are not available, and still undefined.

import { Session, Adapters } from './node_modules/@omegaboot/kahoot-api/';

const session = new Session('000000');
session.openSocket() //Connect
  .then(socket => {
    const player = new Adapters.Player(socket); //Create player class
    player.join('test') //Join with name
      .then(() => {
         console.log('Success!');
      });
  });

There are multiple JavaScript files inside of the kahoot-api folder, and I have tried including each JavaScript file with the JavaScript import, but to no avail.

Also, I am using the code in index.php with a <script> tag with the attribute type="module" as it is needed, or else the following error is thrown:

Cannot use import statement outside a module

Answer 1

Looks like that documentation is wrong because it is based on an old package.

You should install it like:

yarn add @omegaboot/kahoot-api

or

npm i @omegaboot/kahoot-api

if you have webpack (I see that you are using this in php) then use import

import { Session, Adapters } from '@omegaboot/kahoot-api';

otherwise use require

const { Session, Adapters } = require("@omegaboot/kahoot-api")

Answer 2

This worked for me when I tried the module @omegaboot/kahoot-api .

As nodejs does not support import statement and you must use require method if you are not using any bundlers.

const {
  Session,
  Adapters
} = require('@omegaboot/kahoot-api');

const session = new Session('000000');
session.openSocket() //Connect
  .then(socket => {
    const player = new Adapters.Player(socket); //Create player class
    player.join('test') //Join with name
      .then(() => {
        console.log('Success!');
      });
  });

idiidk here (the author of the package)

The package @omegaboot/kahoot-api is not the version that people should be using. This package uses some hard coded defaults for easier integration with our build process for omegaboot.com.

The "normal" kahoot-api package https://www.npmjs.com/package/kahoot-api is to be used by third parties, although it hasn't been updated in a bit. Please open an issue on the github page if anything is broken and I'll be sure to take a look.
