You should be in angular-cli to ng build so cd angular-src folder.
Run ng build to build the project. The build artifacts will be stored in the dist/ directory. Use the -prod flag for a production build.
You can also do the above instructions but I also have choose to do this.
Open angular-src/angular-cli.json and change the "outDir": "../dist" in apps object to "outDir": "../public".
When running ng build, It will automatically save and make a public folder in the main folder.
In my app, I am using MongoDB as a database.
To set up MongoDB database. Go to https://mlab.com.
Create an account or if you already have an account just login.
In https://mlab.com/home page inline with MongoDB Deployments. Create an account.
Below Plan, select Single-node. Then below the Standard Line, select Sandbox.
Then set Database Name below.
Click Users then add database user which will have your username and pass.
Then paste this in your database.js and change database set up which will look like this database: mongodb://<dbuser>:<dbpassword>@ds149820.mlab.com:49820/meanauth
<dbuser> = your user name.
<dbpassword> = your password
