We build a backend: SpringBoot CRUD Application with PostgreSQL that provides RestAPIs for POST/GET/PUT/DELETE data entities and store them in PostgreSQL database. 22 | - We implement React.js CRUD Application that use Ajax to interact (call/receive requests) with SpringBoot CRUD application and display corresponding data in Reactjs Component. 23 | 24 | ## SpringBoot PostgreSQL CRUD Design Application 25 | 26 | ![SpringBoot PostgreSQL CRUD Design Application](https://loizenai.com/wp-content/uploads/2020/10/SpringBoot-PostgreSQL-CRUD-RestAPI-Fullstack-Diagram-Architecture.png) 27 | 28 | I build a SpringBoot project that handle all Post/Get/Put/Delete requests from RestClient and do CRUD operations to PostgreSQL database to save/retrieve/update and delete entity from PostgreSQL and returns back to Restclient the corresponding messages. 29 | 30 | We build a SpringBoot project with 2 layers: 31 | – SpringJPA Repository is used to interact with PostgreSQL database by a set of CRUD operations. 32 | – RestController layer is a web layer for SpringBoot project, it will directly handle all incomming requests and do the corressponding responses to the calling client. 33 | 34 | ## Reactjs CRUD Application Design 35 | 36 | ![Reactjs CRUD Application Design](https://loizenai.com/wp-content/uploads/2020/10/Reactjs-CRUD-RestAPI-Application-Frontend-Architecture-Diagram-2.png) 37 | 38 | – Reactjs CRUD Application is designed with 2 main layers: 39 | 40 | React.js components let you split the UI into independent, reusable pieces, and think about each piece in isolation. 41 | Ajax is used by Reactjs component to fetch (post/put/get/delete) data from remote restapi by http request 42 | 43 | Reactjs CRUD Application defines 5 components: 44 | 45 | - Home.js is used serve as the landing page for your app. 46 | - AppNavbar.js is used to establish a common UI feature between components. 47 | - CustomerList.js is used to show all customers in the web-page 48 | - CustomerEdit.js is used to modify the existed customer 49 | - App.js uses React Router to navigate between components. 50 | 51 | ## Integrative Project Goal 52 | 53 | ![Integrative Project Goal](https://loizenai.com/wp-content/uploads/2020/10/Project-Goal-Customer-List-3.png) 54 | 55 | 56 | Tutorial Link: [SpringBoot + React + PostgreSQL](https://loizenai.com/reactjs-springboot-crud-postgresql/) 57 | 58 | Reactjs + SpringBoot serial: 59 | 60 | Reactjs SpringBoot serial tutorials: 61 | -
