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 files.

• set es5browsersupport: false in angular.json, and got error.
• exclude Chrome 41, IE 9-11 and ie_mob 11 from browserList.

Answer 1

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 2

try changing the tsconfig.json target from es2015back down to es5, this disables differential loading.

Answer 3

in tsconfig.json set target to es2015 if you want to compile for new version first or set it to es5 to disable diffrential loading

"compilerOptions": {
    ...
    "target": "es2015",
    ...
}

and in angular.json change es5BrowserSupport to false

project => app => architect => build => 
"options": {
    ...
    "es5BrowserSupport": false
    ...
}
