import {Youtube} from 'node-youtube-data';
const {Youtube}= require('node-youtube-data');
const api=new Youtube();
- async/await
- promise
- callback function
const response=await api.getVideoInfo('videoId')
if(response){
const data=response.data;
}
api.getVideoInfo('videoId').then(res=>{
if(res){
const data=res.data;
}
})
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 before all we can have two type of videos, encrpted(ciphered) and non-encrypted
Sample response for ciphered video
