Overview : RESTful API for tracking expenses. A RESTful API created using Spring Boot. We have used PostgreSQL as the relational database and JdbcTemplate to interact with that. Apart from this, I have used JSON Web Token (JWT) to add authorization. Using JWT, we can protect certain endpoints and ensure that user must be logged-in to access those.

Using this API , clients can create expense categories and add/remove/update transactions for each of the categories separately. It supports features like total expense record for each categories and searching for categories as well.

Tech Stack Used :

  1. Java
  2. Spring Boot
  3. Maven (build tool)
  4. PostgreSQL

Setup and Installation

  1. Clone the repo from GitHub: git clone [email protected]:anchal00/Expense-Tracker-API.git

  2. cd expense-tracker-api

  3. Make sure you have PostgreSQL installed on your system.

  4. Create database schema

    Use postgres.sql file under expense-tracker-api/Database/, for creating all database objects

    run the script using psql client: psql -U postgres --file postgres.sql

    Note: If your database is hosted at some cloud platform or if you have modified the SQL script file with some different username and password, update the src/main/resources/application.properties file accordingly:

  5. Run the spring boot application ./mvnw spring-boot:run

  6. The server will run on port 8080 and hence all enpoints can be accessed starting from http://localhost:8080
