## Meaning

GraphQL is a query language and runtime for APIs (Application Programming Interfaces) that allows clients to request exactly the data they need, nothing more and nothing less. It provides a structured way to fetch and manipulate data from servers.

GraphQL was developed by Facebook and has become a popular alternative to REST APIs in modern web development. Unlike REST, where endpoints return fixed data structures, GraphQL lets clients specify their exact data requirements in a single request. This reduces over-fetching (getting unnecessary data) and under-fetching (making multiple requests). In tech companies, teams use GraphQL for building flexible APIs that serve multiple client applications, such as web frontends, mobile apps, and third-party integrations. Common use cases include managing microservices, creating real-time applications, and building APIs that serve diverse client needs with varying data requirements.

## When you hear it

We decided to migrate our API from REST to GraphQL to reduce the number of backend requests our mobile app needs to make.

## Examples

- **in a standup:** "We finished the GraphQL schema for the user service yesterday and started integration testing."
- **in a code review:** "This GraphQL mutation should validate the email before updating the user record."
- **in a team meeting:** "Switching to GraphQL reduced our frontend API calls by 40 percent, which improved page load times significantly."

## What native speakers say

- "Let's build a GraphQL API for this project."
- "Our backend is running GraphQL queries efficiently."
- "We switched to GraphQL to improve API performance."

## Common mistakes

- ✗ "We use GraphQL instead of a database." → ✓ "We use GraphQL as a query language for our API layer, which connects to our database." (GraphQL is an API specification, not a database. It is a layer between clients and data sources.)
- ✗ "GraphQL replaced our backend entirely." → ✓ "We implemented GraphQL to handle our API requests more efficiently." (GraphQL is a communication protocol; it works alongside backend infrastructure, not as a complete replacement.)
- ✗ "Everybody prefers GraphQL over REST." → ✓ "GraphQL is advantageous for certain use cases, while REST remains suitable for others depending on project needs." (Neither technology is universally superior; the choice depends on specific requirements, team expertise, and project complexity.)

## Be careful

GraphQL is not a programming language or database; it is a query language and API specification. Do not confuse it with REST or treat it as a replacement for all backend architecture decisions.

## Word forms

| adjective | GraphQL | Our GraphQL endpoint handles all client data requests. |


## Collocations

- **GraphQL API**: The most common phrase; refers to an API built using GraphQL specification
- **GraphQL query**: A request made to a GraphQL API specifying exactly which fields to return
- **GraphQL mutation**: A GraphQL operation that modifies data on the server, similar to POST or PUT in REST
- **GraphQL schema**: The definition of all types, queries, and mutations available in a GraphQL API
- **GraphQL resolver**: A function that fetches or computes the value for a specific field in a GraphQL response

## Synonyms

- **query language**: A general term; GraphQL is a specific query language for APIs
- **API specification**: GraphQL is one type of API specification; REST is another with different design principles

## Opposites

- REST API
- SOAP

## FAQ

### What does GraphQL stand for?

GraphQL stands for Graph Query Language. It is called Graph because it represents data as a graph structure where objects relate to each other through fields and connections.

### How is GraphQL different from REST?

REST uses multiple fixed endpoints that return predefined data structures. GraphQL uses a single endpoint where clients specify exactly which fields they need. This means fewer requests and no over-fetching or under-fetching of data.

### Is GraphQL a programming language?

No, GraphQL is a query language and API specification, not a programming language. You write GraphQL queries to request data, but you implement GraphQL servers using programming languages like JavaScript, Python, Java, or Go.

### When should we use GraphQL instead of REST?

Use GraphQL when you have multiple clients with different data needs, want to reduce API calls, or need flexible querying. Use REST when your API is simple, cacheable, and clients need fixed data structures.

### Is GraphQL formal or informal?

GraphQL is a neutral technical term used in both formal and casual tech conversations. You can use it in interviews, documentation, and daily team discussions without changing your tone.
