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

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

1. Clone the application

   git clone https://github.com/ekta1999/Polling-App.git
   cd Polling-App
   cd polling-app-server

2. Create MySQL database

   create database polling_app

3. 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

4. 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

5. 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.

Steps to Setup the React Front end app (polling-app-client)

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.
