Why GraphQL Beats REST: Problems with REST and How GraphQL Solves Them

After developing several mobile and web applications with GraphQL APIs, the author found the experience superior to REST and outlines REST's shortcomings.

REST lacks a strict standard, leading to inconsistent endpoint design, pagination, filtering, versioning, and documentation, which can consume up to 40% of development time.

GraphQL addresses these issues with a strongly typed schema, automatic validation, precise field selection, built‑in pagination, and introspection, reducing client‑server coordination and eliminating many sources of bugs.

An example GraphQL schema for a Todo‑list application is presented, followed by a sample query and its JSON response.

type Project { id: ID name: String! }

type TodoItem { id: ID description: String! isCompleted: Boolean! dueDate: Date project: Project }

type TodoList { totalCount: Int! items: [TodoItem]! }

type Query { allTodos(limit: Int, offset: Int): TodoList! todoByID(id: ID!): TodoItem }

type Mutation { createTodo(item: TodoItem!): TodoItem deleteTodo(id: ID!): TodoItem updateTodo(id: ID!, newItem: TodoItem!): TodoItem }

schema { query: Query mutation: Mutation }

query {
  allTodos(limit: 5) {
    totalCount
    items {
      id
      description
      isCompleted
    }
  }
}

{
  "data": {
    "allTodos": {
      "totalCount": 42,
      "items": [
        { "id": 1, "description": "write a blogpost", "isCompleted": true },
        { "id": 2, "description": "edit until looks good", "isCompleted": true },
        { "id": 3, "description": "proofread", "isCompleted": false },
        { "id": 4, "description": "publish on the website", "isCompleted": false },
        { "id": 5, "description": "share", "isCompleted": false }
      ]
    }
  }
}

Tools such as PostGraphile and Apollo provide ready‑made implementations, automatic documentation, and type‑safe client libraries, making GraphQL practical for production environments.

The author concludes that GraphQL’s ecosystem, strong tooling, and ability to solve many REST pain points make it a compelling choice for modern API development.
