how to turn off differential loading in Angular v8?

Question

Angular-CLI v8 implemented differential loading. But I don\'t need files built by es5. I want to decrease deploy quantity.

I tried below. But CLI has generated es5 f

Answer 1

Simply

> 5.0%
last 1 edge versions

will do the job

Answer 2

Fastest solution: Switch back to es5 as compilation target in your tsconfig.json.

"compilerOptions": {
        ...
        "target": "es5"
        ...
}

As mentioned on Angular official documentation (https://angular.io/guide/deployment#differential-loading):

To explicitly disable differential loading:

• Enable the dead or IE browsers in the browserslist config file by removing the not keyword in front of them.
• Set the target in the compilerOptions to es5.

Answer 3

I succeeded to build without es5 files in Angular v8-rc4.

set like below in browserList to make isEs5SupportNeeded false in build-angular.

Answer 4

At the moment many people have es5 bundle generated because @angular/cli does not consider latest Edge (i.e., Edge 18) to be es2015-modules compliant: https://github.com/angular/angular-cli/issues/14580.

A dirty fix is to exclude Edge from the list of browsers you support (in the browserslist file). This problem should be fixed if you upgrade to @angular/cli 8.1.0.
