# Poke Evolution Chain

This project aims to provide a solution for retrieving the evolution chain and variations of a Pokémon using the Poke API. It utilizes Node.js and Express to create a server that serves the evolution chain information as a JSON response.

## Prerequisites

- Node.js (version 20.3.0)
- npm (version 9.6.7)

## Getting Started

1. Clone the repository:

   ```shell
   git clone https://github.com/nitinmaram/poke-evolution-chain

2. Install the dependencies:

   cd poke-evolution-chain
   npm install

3. Start the server:

   npm start

   The server will be running at http://localhost:3000.

To retrieve the evolution chain information for a Pokémon, make a GET request to the following endpoint:

GET /evolution-chain/:pokemonName

Replace :pokemonName with the name of the Pokémon you want to retrieve the evolution chain for(eg. pikachu).

The server will respond with a JSON object representing the evolution chain and variations of the Pokémon.

Retrieves the evolution chain and variations of a Pokémon.

• Parameters:

  • pokemonName (string): The name of the Pokémon.

• Response:

  • Status: 200 OK

  • Body: JSON object representing the evolution chain and variations. The structure will be as follows:

    {
      "name": "caterpie",
      "variations": [
        {
          "name": "metapod",
          "variations": [
            {
              "name": "butterfree",
              "variations": []
            }
          ]
        }
      ]
    }

    The name field represents the name of the Pokémon and the variations field contains an array of similar objects representing the variations in the evolution chain.

• Error Responses:

  • Status: 404 Not Found

    • Body: {"error": "Pokemon not found."}

  • Status: 500 Internal Server Error

    • Body: {"error": "Internal server error."}
