I didn't install all the things you mentioned above, my config has most of the web layers enabled: html, react, typescript, javascript. I cloned this sample repo https://github.com/DanWahlin/Angular-HelloWorld, then opened the src/index.html file in Spacemacs, after that M-x: lsp, I got a complaint from lsp: Server angular-ls:17150/starting exited with status exit(check corresponding stderr buffer for details). Do you want to restart it? (y or n) n. It means lsp recognized the anglular ceremony but it couldn't find the server because I didn't set up the server yet. It also means angular on Spacemacs is possible.
