The RestaurantGraphQL API is a GraphQL-based API designed to handle multiple restaurants in a shop store. It provides various features such as searching for restaurants in a city, finding the nearest restaurant, retrieving a list of foods offered by a restaurant, and more. This README file provides an overview of the API and instructions on how to use it.
The RestaurantGraphQL API offers the following features:
- Search in a city: Users can search for restaurants in a specific city by providing the city name as a parameter.
- Distance calculation: The API can calculate the distance between a given location and all the restaurants, enabling users to find the nearest restaurant.
- Retrieve restaurant details: Users can retrieve detailed information about a specific restaurant, including its name, address, contact details, opening hours, and more.
- Get a list of foods: The API allows users to fetch a list of foods offered by a restaurant, including their names, descriptions, prices, and any other relevant details.
- Filtering: Users can apply various filters while searching for restaurants, such as food , price range, ratings, and more.
To run the RestaurantGraphQL API locally, follow these steps:
Clone the repository:
git clone https://github.com/BaseMax/RestaurantGraphQLNavigate to the project directory:
cd RestaurantGraphQLInstall the dependencies:
npm installSet up the environment variables:
- Create a
.envfile in the project root. - Define the necessary environment variables, such as the database connection details and API keys.
Start the server:
npm startThe API will be available at http://localhost:3000.
To interact with the RestaurantGraphQL API, you need a GraphQL client or an API testing tool. Here's an example using cURL:
Make a POST request to the API endpoint (http://localhost:3000/graphql) with the following headers:
Content-Type: application/jsonSend a GraphQL query as the request payload. Here's an example query to search for restaurants in a city:
query RestaurantByCity($city: String!) {
restaurantByCity(city: $city) {
name
_id
location {
latitude
longitude
}
foods {
price
name
description
}
}
}Replace "New York" with the desired city name.
Receive the response from the server, containing the list of restaurants in the specified city.
For detailed documentation on the available queries, mutations, and types, refer to the API documentation or the GraphQL schema.
