Angular 10: Is it possible to run and build Angular 10 project with only es2015 (Any One of this)?
I am using Angular CLI v10.2.4, My build process is taking around 15-20 minutes for each production builds because it builds es5 and es2015 version both. Is it possible to build a project with only es2015 / es2016 / es2017? (Any one of them?)
I changed my tsconfig file as below, but didn't see a working solution yet!
{ "extends": "../tsconfig.json", "compilerOptions": { "outDir": "../out-tsc/app", "baseUrl": "", "module": "es2015", //<------------------------------ es2015 "types": [ "node" ],"typeRoots": [ "../node_modules/@types" ] }, "exclude": [ "test.ts", "**/*.spec.ts" ]}Any help will be appreciated.

Yes, it is possible.
#Approach 1: If you want to use package.json file to maintain your browser support, add the following code.
#Approach 2: Add `.browserslistrc` file to your root directory of your angular project and add your browser supports in that file.
If you want to build your production build release only capable of ES2015 for particular browsers, only one build should be created.
Note: only chrome makes it into the list with >5%
If you don't want firefox, IE and edge browsers, You can use following browserslist array entries. Put the word not at the begin of every line which browser support you don't want.
This will fix your double prod build time and so I saved you a lot of time!
