To install saga-frontend on your machine you need to have the following tools installed:
git clone https://github.com/apache/servicecomb-pack
cd servicecomb-pack/saga-web/src/main/resources/saga-frontend && npm i
npm start
Go to http://0.0.0.0:4200 or http://localhost:4200 in your browser.
npm run build:prod
This will clear up your dist folder (where release files are located) and generate a release build. Now you can copy the sources from the dist folder and simply put it under the static folder or under a web server.
