ScholarX - backend application and auth server

Backend of the ScholarX project

Setting up the project for development

Prerequisites

• Java
• Maven
• PostgreSQL
• Google Developer Account
• Gmail Account with an App Password

Setup Google Auth Client

Here are the steps you need to follow to configure Google for social login:

• Go to https://console.developers.google.com/ and register for a developer account.
• Create a Google API Console project.
• Once your Google App is open, click on the Credentials menu and then Create Credentials followed by Auth client ID.
• Select Web Application as the Application type.
• Give the client a name.
• Fill in the Authorized redirect URIs field to include the redirect URI to your app: http://<your-domain>/login/oauth2/code/google.
  • example: http://localhost:8080/login/oauth2/code/google
• Click Create. Copy the client ID and client secret, as you'll need them later.

Setup a gmail account with an app password

1. Create a new gmail account if you don't have one already
2. Enable Two Factor Authorisation
3. Generate a new App Password (help?)

Run Locally

1. Fork and clone the repository

git clone https://github.com/<your profile name>/scholarx

2. Open the cloned repo, Find and open the application.yml file
3. Replace the ${CLIENT_ID} and ${CLIENT-SECRET} with the values from the above google auth client setup.
   example:

        google:
            client-id: 123456789123-456rtyfghvbnyui.apps.googleusercontent.com
            client-secret: ABCDEF-qweqrtyuiopasdfghjklzxcv

4. Replace the datasource dummy values with your local postgresql server instance credentials
   example:

  datasource:
    url: jdbc:postgresql://localhost:5432/scholarx_DB?allowPublicKeyRetrieval=true&useSSL=false&useUnicode=true&characterEncoding=UTF-8
    username: rootuser
    password: rootpassword
    platform: postgres

5. Find and open the simplejavamail.properties file. Replace the mail ${EMAIL} and ${APP_PASSWORD} values with the generated App Password and the corresponding gmail address
   example:

  simplejavamail.smtp.username = [email protected]
  simplejavamail.smtp.password = ytrewwqlkjmkolkj

6. Update the SecurityConfig.java to allow requests from the origin http://localhost:3000. The file path is scholarx/src/main/java/org/sefglobal/scholarx/config/SecurityConfig.java
   example:

  configuration.setAllowedOrigins(ImmutableList.of("http://localhost:3000"));

7. Run the application

mvn spring-boot:run

Configuring a MySQL Database (Optional)

1. Add the mysql-connector-java dependency to the pom.xml file.

<dependency>
  <groupId>mysql</groupId>
  <artifactId>mysql-connector-java</artifactId>
  <scope>runtime</scope>
</dependency>

2. Replace the spring.jpa and spring.datasource configurations in application.yml with the following configuration.

  jpa:
    database: postgresql
    hibernate:
      ddl-auto: update
  datasource:
    url: jdbc:postgresql://${DB_URL}/${DB_NAME}?allowPublicKeyRetrieval=true&useSSL=false&useUnicode=true&characterEncoding=UTF-8
    username: ${DB_USER_NAME}
    password: ${DB_USER_PASSWORD}
    platform: postgres
