Building a Full Stack Polls app similar to twitter polls with Spring Boot, Spring Security, JWT, React and Ant Design

I've written a complete tutorial series for this application on The CalliCoder Blog -

Part 1: Bootstrapping the Project and creating the basic domain models and repositories
Part 2: Configuring Spring Security along with JWT authentication and Building Rest APIs for Login and SignUp
Part 3: Building Rest APIs for creating Polls, voting for a choice in a Poll, retrieving user profile etc
Part 4: Building the front-end using React and Ant Design

Steps to Setup the Spring Boot Back end app (polling-app-server)

Clone the application

git clone https://github.com/callicoder/spring-security-react-ant-design-polls-app.git
cd polling-app-server

Create MySQL database
```
create database polling_app
```
Change MySQL username and password as per your MySQL installation
- open src/main/resources/application.properties file.
- change spring.datasource.username and spring.datasource.password properties as per your mysql installation
Run the app

You can run the spring boot app by typing the following command -
```
mvn spring-boot:run
```
The server will start on port 8080.

You can also package the application in the form of a jar file and then run it like so -
```
mvn package
java -jar target/polls-0.0.1-SNAPSHOT.jar
```
Default Roles

The spring boot app uses role based authorization powered by spring security. To add the default roles in the database, I have added the following sql queries in src/main/resources/data.sql file. Spring boot will automatically execute this script on startup -
```
INSERT IGNORE INTO roles(name) VALUES('ROLE_USER');
INSERT IGNORE INTO roles(name) VALUES('ROLE_ADMIN');
```
Any new user who signs up to the app is assigned the ROLE_USER by default.

First go to the polling-app-client folder -

cd polling-app-client

Then type the following command to install the dependencies and start the application -

npm install && npm start

The front-end server will start on port 3000.
