How can i make fluent-ffmpeg to work in angular 8

I'have installed 'fluent-ffmpeg' plugin in my project and I added it to my angular project this way var ffmpeg = require('fluent-ffmpeg') and i also used this method import * as ffmpeg from 'fluent-ffmpeg'

I'm getting the following issues while building using ng serve
