Getting Started

Prerequisites

• Docker and Docker Compose
• Git

Installation

1. Clone the repository:

   git clone https://github.com/yourusername/graphql-comparison-operators.git
   cd graphql-comparison-operators

2. Build the Docker containers:

   docker-compose build

3. Start the application:

   docker-compose up

4. Access the GraphQL playground at:

   http://0.0.0.0:8000/graphql
   

Create a New Task

Query Tasks with Filters

Filter by creation date (greater than)

{
  tasks(
    query: {
      createdAt: {
        gt: "2023-06-19T12:21:35.640+00:00"
      }
    }
  ) {
    id
    content
    createdAt
  }
}

Filter with multiple conditions

{
  tasks(
    query: {
      createdAt: {
        gte: "2023-06-01T00:00:00.000+00:00",
        lte: "2025-03-03T07:48:11.572456"
