@Java Techie The user.ts class just has a constructor with no class members in it ( pardon me for Java terminology ). I was not able to execute your code 'cos the compiler was throwing and error at registration.component.html stating that name ( and others) property is not identified for User type. When I added the missing class members in user.ts the code works fine.

From ngOnInit() did you call getAll() method as I wrote . Search should work please inspect it and verify request is going or not

[@GlennMartin]

Nice tutorial Java Techie!!! One question, how do you run this in production? shouldn't there be a build command which builds the angular and dumps the JS files into the spring boot resources folder for spring boot to pick up?

[@Javatechie]

Yes in production we shouldn't use this codebase We need to generate prod build then it will generate dist folder with all compiled files

[@GlennMartin]

Java Techie ah ok thought so. Any guides on how to do this? Or is it the same as with react bundle.js?

Hi, thanks for your video. One question. In spring boot, the base url is localhost:9090. Then you use it in angular. My question if you don't hard code it, how can you pass it from spring boot to angular? The base url maybe dynamically changed.

NgModel is used to perform 2 way data binding Basically form input I want to bind into Product.ts object . So I believe your error because you didn't save your file .
