Need help in deploying a mean stack application on a ubuntu server.

Git repo available. Currently hosted on heroku. Want to move it to ubuntu 18.04LTS or 16.04LTS (32/64bits) whichever is convenient. Note: For mongodb we will continue to use mlab instead of self hosted mongodb. Below is glimpse of [login to view URL] file. "engines": { "node": ">8.9.x", "npm": ">5.5.x" } "scripts": { "dev": "run-p createappjsfile serverw client ", "prod": "run-p server:compile build", "start": "node server/[login to view URL]", "client": "ng serve --proxy-config [login to view URL]", "server": "run-s server:compile server:run ", "serverw": "run-p server:compilew server:run", "heroku": "git push heroku master", "server:compilew": "tsc -w -p server", "server:compile": "tsc -p server", "server:run": "node-dev --no-notify dist/server/server/[login to view URL]", "precommit": "npm run lint", "createappjsfile": "node devops/create-app-js-file", "copy": "node copy-dist-files", "ng": "ng", "build": "ng build", "test": "ng test", "lint": "ng lint", "e2e": "ng e2e" }, Deliverables: Complete server setup Application should notify/restart if it crashes
