Employee Leave Management API

The Employee Leave Management API is a Go language HTTP API built using the GoFr framework. It provides endpoints for managing employee leaves, including operations such as creating a leave request, updating leave details, retrieving leave information, and deleting leave records.

Prerequisites

Before running the project, ensure you have the following installed:

• Go (Version 1.16 or later)
• Git
• GoFr
• Make sure to install it using the following command:

  go get gofr.dev
  

• Docker
• To simplify the setup and management of the database for your REST API, consider using a Docker image for SQL.

Running the Project

1. Clone the repository:

   git clone https://github.com/Pratishtha33/Go.git
   

2. change the directory

   cd .\Go
   

3. Install Dependencies:

   go get -u ./...
   

4. Build and Run the Application:

   go run main.go
   
   

Gofr

• GoFr seamlessly integrates with GORM for efficient database management. GoFr has ingeniously incorporated various datastores, including PostgreSQL, Redis, MongoDB, SQL and Cassandra, simplifying the process of connecting to and managing different databases.

Overview

The Employee Leave Management is an HTTP API that facilitates the management of employee leaves. It provides endpoints to perform CRUD operations on leave records, allowing employee handle employee leave requests.

Code Structure

The codebase is organized into several packages, each serving a specific purpose:

• datastore: Implements the data storage and retrieval logic for leave records.
• handler: Defines HTTP handlers for processing leave-related requests.
• model: Contains data models representing the entities used in the system.
