Shareable TypeScript config for Angular projects

Quick start

$ npm install @angular-ru/tsconfig -D

Add to your tsconfig.json:

{
    extends: '@angular-ru/tsconfig',
    angularCompilerOptions: {
        // override shared angularCompilerOptions
        strictTemplates: true,
        disableTypeScriptVersionCheck: true
    },
    compilerOptions: {
        // override shared compilerOptions
        outDir: 'dist',
        target: 'es2018',
        lib: ['es2018'],
        typeRoots: ['./node_modules/@types']
    }
}

If you want to know which properties were inherited, you can do:

$ tsc --showConfig --project tsconfig.json

FAQ

• Uncaught ReferenceError: __importDefault is not defined in my Angular 8 project

In the eighth version, this is not fixed, so you need to add such a line:

polyfils.ts

(window as any)['__importDefault'] =
    (this && (this as any).__importDefault) ||
    function (mod: any): any {
        return mod && mod.__esModule ? mod : { default: mod };
    };

If you use Angular 9, this does not need to be done

// fixed since
"@angular-devkit/build-angular": "~0.900.0"
