node-youtube-data v1.0.0
YoutubeData
Typescript or ES6
import {YoutubeData} from 'node-youtube-data';
Common js
const YoutubeData= require('node-youtube-data');
Create instance of YoutubeData
const api=new YoutubeData();
To retrive YoutubeVideo data ,will need to use getVideoInfo method
There are 3 ways to use it ,by using :-
- async/await
- promise
- callback function
How to use getVideoInfo with async/await
function must be wrapped inside async method
const response=await api.getVideoInfo('videoId')
if(response){
const data=response.data;
}How to use getVideoInfo with Promise
api.getVideoInfo('videoId').then(res=>{
if(res){
const data=res.data;
}
})How to use getVideoInfo with Callback
api.getVideoInfo('videoId',(errors,data)=>{
const data=data;
})The data response from Youtube is very big Json object but the interesting part is video url ,but beafore all we can have two type of videos, encrpted(ciphered) non-encrypted
sample response for ciphered video
