GraphQL-Parser

A simple GraphQL parser written in C++. This parser can parse GraphQL queries and convert them to JSON.

Features

• Parsing GraphQL queries
• Converting GraphQL queries to JSON
• Handling errors
• Handling nested queries
• Handling variables

Requirements

• C++11 compiler
• nlohmann/json library

Installation

git clone https://github.com/Bhavyyadav25/GraphQL-Parser.git cd GraphQL-Parser cmake . make

Usage

1. Put your GraphQL query in query.graphql.

2. Compile the parser by running the following command:

g++ graphql.cc -o <graphql>

• You can put any name for the build file, and replace <graphql> with the name of your build file.

3. Run the build file by running the following command:

./graphql

• This will parse the GraphQL query in query.graphql and print the JSON representation of the query to the console.

Example

query {
  getTask(id: "0x3") {
    id
    title
    completed
  }
  getUser(username: "dgraphlabs") {
    username
  }
}

This is a valid GraphQL query that can be parsed by the parser. The output of the parser will be the following JSON:

{
  "JSON": [
    {
      "JSON": [
        {
          "name": "id"
        },
        {
          "name": "title"
        },
        {
          "name": "completed"
        }
      ],
      "name": "getTask"
    },
    {
      "JSON": [
        {
          "name": "username"
        }
      ],
      "name": "getUser"
    }
  ],
  "name": "query"
}
