Angular IE11 not working. Getting SCRIPT1002 Syntax Error

Question

Trying to get Angular to work in IE 11. I tried everything I found on the web already.

I'm getting the following errors:

SCRIPT1002: Syntax error

File: polyfills.js, Line: 2358, Column: 1

Line 2358

class Disposable {

    /**
     * Frees internal resources.
     */

    dispose() {}

}

SCRIPT1002: Syntax error

File: scripts.js, Line: 424, Column: 35

line 424

let SoapService = SoapService_1 = class SoapService {
    constructor(servicePort, servicePath, targetNamespace) {
        this.debug = false;
        this.asynchronous = true;
        this.localName = false;
        this.servicePort = '';
        this.servicePath = '';
        this.serviceUrl = '';
        this.targetNamespace = '';
        this.envelopeBuilder_ = null;
        this.xmlResponseHandler_ = null;
        this.jsoResponseHandler_ = null;
        this.servicePort = servicePort;
        this.servicePath = servicePath;
        this.serviceUrl = servicePort + servicePath;
        if (undefined !== targetNamespace)
            this.targetNamespace = targetNamespace;
    }

SCRIPT1002: Syntax error

File: vendor.js, Line: 88, Column: 1

Line 88

class AnimationBuilder {
}

SCRIPT1002: Syntax error

File: main.js, Line: 91422, Column: 35

Line 91422 Same as above

    let SoapService = SoapService_1 = class SoapService {
        constructor(servicePort, servicePath, targetNamespace) {
....

I do have a soap connection which wont work on localhost anyway. So thats probably not the problem

Added this line in main.ts

/// <reference path= "../node_modules/typescript/lib/lib.es6.d.ts" />

Added this script in index.html

<script src="/node_modules/core-js/client/shim.min.js"></script>

I also have a tsconfig.app.json and tsconfig.spec.json

Solution

For others running across similar issues:

Angular 8 has made the default target es2015 instead of es5

You'll want to create a tsconfig.es5.json so that you only run on es5 in development mode, but more information on that can be found here: https://github.com/angular/angular-cli/issues/14455

You'll also want to uncomment the polyfills in polyfills.ts depending on what you are using.

For others and for the asker:

Then, you'll want to add a flag to zone.js

Add import './zone-flags.ts'; before import 'zone.js/dist/zone'; then create the zone-flags.ts file in the same directory as the polyfills.ts.

In the zone-flags.ts file add the following line:

(window as any).__Zone_enable_cross_context_check = true;

Hopefully after that everything is working! If you followed the link above,

Execute: ng serve --configuration es5 to run your project in IE in development mode.

Update

It looks like angular actually has documentation on this: angular.io/guide/deployment#fallback

Look for "Local development in older browsers" and then "Configuring serve for ES5"

The issue is caused by Angular 8's differential loading process.
