Hello Piyush There are many ways that you can optimise your angular application to reduce the build time. How to optimize an angular app ? Consider lazy loading instead of fully bundled app If the app size is more Make sure that any 3 rd party library ,which is not used ,is removed from the application Have all dependencies and dev-dependencies are clearly separated. Make sure the application doesn’t have un necessary import statements Consider AOT compilation You can use --ng build --prod --aot to reduce the vendor package ---------------------------------------------------------------------------------------------------------------------- To upgrade Angular Application Upgrade manually Angular CLI (Global) npm install @angular/cli@9.0.0 -g Angular Dependencies(Local) npm install @angular/animations@9.0.0 @angular/common@9.0.0 angular/compiler@9.0.0 @angular/core@9.0.0 @angular/forms@9.0.0 @angular/http@9.0.0 @angular/platform-browser@9.0.0 angular/platform-browser-dynamic@9.0.0 @angular/router@9.0.0 Angular DevDependencies(Local) npm install @angular/compiler-cli@9.0.0 @angular-devkit/build-angular@9.0.0 @angular/cli@9.0.0 @angular/language-service@9.0.0 --save dev All Other Related Dependencies npm install core -js@latest zone.js@latest rxjs@latest All Other Related DevDependencies npm install @types/jasmine@latest @types/node@latest codelyzer@latest karma@latest karma-chrome-launcher@latest karma-cli@latest karma-jasmine@latest karma-jasmine-html-reporter@latest jasmine-core@latest jasmine-spec-reporter@latest protractor@latest tslint@latest webpack@latest rxjs-tslint@latest --save-dev Upgrade Typescript npm i typescript@3.1.6 --save-dev --save-exact Thanks
