Repro steps

• I'm importing the following in polyfills.ts:
  ts import 'intl'; import 'intl/locale-data/jsonp/en';

Observed behavior

On app startup, I see the following error:

index.js:2 Uncaught ReferenceError: global is not defined
    at eval (index.js:2)
    at Object../node_modules/intl/index.js (polyfills.js:2880)
    at __webpack_require__ (runtime.js:75)
    at eval (polyfills.ts:36)
    at Object../src/polyfills.ts (polyfills.js:2926)
    at __webpack_require__ (runtime.js:75)
    at Object.1 (polyfills.js:2937)
    at __webpack_require__ (runtime.js:75)
    at checkDeferredModules (runtime.js:44)
    at Array.webpackJsonpCallback [as push] (runtime.js:31)

where index.js is the following:

// Expose `IntlPolyfill` as global to add locale data into runtime later on.
global.IntlPolyfill = require('./lib/core.js');

// Require all locale data for `Intl`. This module will be
// ignored when bundling for the browser with Browserify/Webpack.
require('./locale-data/complete.js');

// hack to export the polyfill as global Intl if needed
if (!global.Intl) {
    global.Intl = global.IntlPolyfill;
    global.IntlPolyfill.__applyLocaleSensitivePrototypes();
}

// providing an idiomatic api for the nodejs version of this module
module.exports = global.IntlPolyfill;

It doesn't crash the application, although the browser I'm using doesn't need the polyfill. But I wouldn't expect to see this error normally.

^^^ That was a bug and is fixed in master

As to the issue, the value global does not exist in a web browser. Node shims have been removed in 6.0. For more details on why, please see this comment: https://github.com/angular/angular-cli/issues/9827#issuecomment-369578814

The polyfill in question is also no longer needed by Angular as mentioned in the changelog for 5.0: https://github.com/angular/angular/blob/master/CHANGELOG.md#500-pentagonal-donut-2017-11-01

I'm having the exact same issue after upgrading my project to angular 6. Is there a solution for it? I'm not really understanding how to solve it from the reply above.

[MattMorrisDev]

@shiamalon Remove the intl imports completely - they aren't needed in v6.

[takahser]

for those, who get the slightly different error ReferenceError: global is not defined at Object.getWindow, this is the fix:

add to polyfill.ts:
(window as any).global = window;

see: https://github.com/auth0/auth0.js/issues/753

[MateWW]

For me polyfills.js from project generated by latest cli solved problem :)

Had the same issue after upgrading to angular 6 with @angular/cli ng update

Fixed it by adding

import 'intl';

to polyfills.ts

[shiamalon]

@MattMorrisDev thank's!

@shiamalon Remove the intl imports completely - they aren't needed in v6.

I just had to use @takahser 's fix using a fresh install of angular cli 6.1.0-rc.3 in order to use Buffer

what fixed for me: npm install --save-dev intl.
I guess what broke it here is that i installed testing frameworks through angular cli and then changed the app file.
Now everything up and running! =)

In case, if your target is node in webpack (target: 'node'), because you want to fix "Can't resolve 'fs'. Then you're getting the following error Fix: "Uncaught ReferenceError: global is not defined" do it as follows node: { global: true, fs: 'empty' }. Bonus: if you got error "Uncaught ReferenceError: exports is not defined". simply add libraryTarget: 'umd'. The complete webpack config code is below.

const webpackConfig = {
  node: { global: true, fs: 'empty' }, // Fix: "Uncaught ReferenceError: global is not defined", and "Can't resolve 'fs'".
  output: {
    libraryTarget: 'umd' // Fix: "Uncaught ReferenceError: exports is not defined".
  }
};

module.exports = webpackConfig; // Export all custom Webpack configs.
