how to generate video thumbnail in node.js?

Question

I am building an app with node.js, I successfully uploaded the video, but I need to generate a video thumbnail for it. Currently I use node exec to execute a system command

Instead I would recommend using thumbsupply. In addition to provide you with thumbnails, it caches them to improve performance significantly.

npm install --save thumbsuppply

After installing the module, you can use it in a following way.

const thumbsupply = require('thumbsupply')("com.example.application");

thumbsupply.generateThumbnail('some-video.mp4')
.then(thumb => {
    // serve thumbnail
})
