Even though I am using target esm2015, ivy is compiles as a esm5 module

Question

@angular ivy issue

Description

When I use the ng cli, it compiles the modules as esm2015, my problem is that I have an old system since angular 2 times and I use webpack, but for me it compiles to es5.

How can I change it to compile to esm2015?

🔥 Exception or Error

not directly error, but i target for esm2015

🌍 Your Environment

Angular Version: 8.1.2

Anything else relevant?

build error, i am expecting like :

Compiling @angular/core : es2015 as esm2015

Compiling @angular/common : es2015 as esm2015

Compiling @angular/platform-browser : es2015 as esm2015

Compiling @angular/platform-browser-dynamic : es2015 as esm2015

Answer 1

For me this started showing after upgrading to Angular 9, and adding

"postinstall": "ngcc"

to scripts in package.json fixed it.

Answer 2

ok,i, found it, in webpack i had to set [ 'es2015', 'browser', 'module', 'main'],,
