Short description of the problem:

1. uglifyjs raise an error when js lib not having sourcemap
2. Chart.js and another js lib are involved. Since lots of ppl are using Chart.js, they will report this bug sooner or later, in here or somewhere else. So please don't ignore this bug.
3. I never had problem on this problem before upgrading to 1.3.1

What behavior are you expecting?

At least compiling without error. May be skip uglifying the js lib without sourcemap.

Steps to reproduce:

1. Installing ng-charts@1.5.0 and chart.js@2.5.0 thru npm
2. Copying node_modules/chart.js/dist/Chart.js to www/build as doc requested
3. Including Chart.js in the index.html as doc requested
4. running ionic build android --prod --release

I tried Chart.js and Chart.min.js, the results are the same

insert any relevant code between the above and below backticks

Which @ionic/app-scripts version are you using?
1.3.1

1.2.5 won't raise this error, but it will fail by another error(BuildError.Error (native)) See #853
1.1.4 won't raise this error, but it will fail because of javascript HEAP MEMORY. See #808

So now we got no working version of ionic-app-scripts : (

I get the same error with any plain js files I include in the build. @danbucholtz this is the issue I mentioned you in on Friday.

[danbucholtz]

Working on this now.

Thanks,

I did a grotesque hack of uglifyjs.js to work around the issue for myself, will appreciate a legit fix ;)

if (path_1.extname(file) === '.js'
        && file.indexOf('polyfills') === -1
        && file.indexOf('sw-toolbox') === -1
        && file.indexOf('.map') === -1
        && file.indexOf('appSettings') === -1

This is fixed in 1.3.2.

Thanks,

I just want to confirm 1.3.2 fixed this bug. And thanks, ionic team.
