Building production using ng build --prod results with the following error:
ERROR in vendor.6524f61fda4d53a6f933.bundle.js from UglifyJs Unexpected token: name (Time) [vendor.6524f61fda4d53a6f933.bundle.js:18068,6]

I can't find Time in my project path, i think it is from some of the libraries i use.

Before i updated Angular, and Angular CLI
I used Angular 4.1.3 and Angular CLI 1.0.6 and I was getting similar error but insted of Time, unexpected token was PolicyMappings which was from pkijs

I also found Time class in pkijs

ng build --prod

@AKuzmanoski Are you getting any errors while running the dev build?

No, it works fine on dev mode

I've started hitting this -

ERROR in main.1dae05ad85948e9171be.bundle.js from UglifyJs
Unexpected token: name (TaskTableComponent) [main.1dae05ad85948e9171be.bundle.js:53,6]
``

In my case, `TaskTableComponent` is a component defined in my app, loaded in the module

import { TaskTableComponent } from './task-table/task-table.component';


and I get no errors in dev mode (the component also works just fine)

Can you share some details abot TaskTableComponent?

I may have found the problem - I had a target of es6, because es5 was causing me problems with
this.allowedFields = [ ...new Set(this.allowedFields) ].sort((a,b) => { return a.toLowerCase() > b.toLowerCase() ? 1 : -1});

I think that es6 does not compile properly with uglify.js , which may be throwing out the errors

Any idea on how I can get uglify to work with es6 ?

I've resolved this using UglifyJS2#harmony-v2.8.22 --dev for ES6:

yarn add git://github.com/mishoo/UglifyJS2#harmony-v2.8.22 --dev

documented at: https://www.npmjs.com/package/uglifyjs-webpack-plugin

I changed compilerOptions.target from es6 to es5 and this error disappeared.

I have compilerOptions.target of es5 and still have ERROR from UglifyJS. I figured it's because I'm using pify package that's ES6. Still haven't found a solution yet.

I have the same issue, with a library required by AutobahnJS called cbor. There I get this error when trying to build with --prod:

ERROR in vendor.f46aa55cec82811ad623.bundle.js from UglifyJs
Unexpected token: name (Decoder) [[...]/node_modules/cbor/lib/decoder.js:48,0][vendor.f46aa55cec82811ad623.bundle.js:23235,6]

Anyone have a solution?

Same problem for me with quilljs when i try to create a custom theme based on snow theme, when i run "ng build --prod" :

ERROR in main.b5edce071b49acaa29f7.bundle.js from UglifyJs
Unexpected token: name (MyCustomTheme) [main.b5edce071b49acaa29f7.bundle.js:30679,6]

ERROR in vendor.f179b6171896e95f4169.bundle.js from UglifyJs
Unexpected token: name (debug) [vendor.f179b6171896e95f4169.bundle.js:16561,4]

Please give us a solution/workaround

I think all these issues are supposed to be gathered in #2907

I can confirm this issue. Only happens when I set the target to es6. Using es5 the issue is not there.

I changed compilerOptions.target from es6 to es5 and OK too.

I as well can confirm that you can't switch back the target to es5 if you have package like SignalR core which propably uses es6.

Upgrade to a newer version of angular-cli, this has been fixed for a little while now: #7610

Matches signalr version with server and upgrades angular cli
