Repro steps

• ng new jszip-test
• cd .\jszip-test\
• npm i --save jszip
• Add the following code in app.component.ts:

import * as JSZip from 'jszip';
...
constructor() {
    const zip = new JSZip();
}

• ng build

Observed behavior

ERROR in ./node_modules/jszip/lib/readable-stream-browser.js
Module not found: Error: Can't resolve 'stream' in 'C:\dev\jszip-test\node_modules\jszip\lib'

Desired behavior

Should be able to build a project without errors.

Mention any other details that might be useful (optional)

This works as expected with angular-cli 1.7

npm i stream - worked for me

It was hot fix. Right fix: tsconfig.json
