What we are building 🛠
We are going to be building an api that we are going to set up using Java Spring Boot (which you all are familiar with to some degree) in the chance you were snoozing in LC101 lets go over it again real quick.
Spring is a framework that makes writing Java applications easier and more maintainable. Spring has many packages that can be used to develop applications. The main one we are going to talk about at this moment is Spring Boot. Spring Boot is what makes this code right here get instantiated first and foremost at compile/ runtime. This code is both making a new class which we will need right away at runtime. There is a big difference between the two because it both cases I want this to be the first thing I call.
A
@Service
public class LabradoodleService {
private LabradoodleRepository labradoodleRepository;
public LabraoodleService(LabradoodleRepository labradoodleRepository) {
this.labradoodleRepository = labradoodleRepository;
}
public Labradoodle getGavinsDog() {
return labradoodleRepository.findByOwnersName("Gavin");
}
}B
public class LabradoodleService {
private LabradoodleRepository labradoodleRepository;
public LabraoodleService(LabradoodleRepository labradoodleRepository) {
this.labradoodleRepository = labradoodleRepository;
}
public Labradoodle getGavinsDog() {
return labradoodleRepository.findByOwnersName("Gavin");
}
}What is the difference between these two, well in figure B I would get an exception because no one has newed up an instance of LabradoodleRepository to call. In figure A we have though so that would be successful if that was the first thing we called. There is more to it than this but the main concept is that @Service which tells Spring Boot to auto wire the constructor of that class and it will new up the objects for us so they are available right away.
We are going to use that same annoation to set up @RestController that will work to expose some urls for us to hit. Its going to be fun.
Next I will talk about React.
Why React is the best ⚛️
I love React its super fun and there is a ton of people in the open source community working on super neat things with React. I am not going to go into much detail about React because there is SOOOO much stuff that it would take you forever to watch all the videos.
What I will say is I love REACT. Its so neat and fun to build UIs in. The main point of my piece on this is if Spring Boot is going to manage our data and have controllers, React is going to be the V in MVC. Its going to be the view and its going to be nice so lets get started.
