Question

I am converting React code to typescript, target in tsconfig is es5.

on running in IE 11 i get an error \"Promise is undefined\"

I know i need to polyfill,bu

Answer 1

var ES6Promise = require("es6-promise");
ES6Promise.polyfill();
var axios = require("axios");

writing this above axios worked for me maybe other options also worked

it was mainly a cache issue in IE that i was facing

installing es6-promise-promise webpack plugin also worked

npm install es6-promise-promise

and include

new webpack.ProvidePlugin({
    Promise: 'es6-promise-promise', // works as expected
});

in webpack plugins

i will edit this answer with more possible options
