GraphQL Overview
GraphQL is an open-source query language developed by Facebook in 2012 and later released as an open-source project in 2015. It allows clients to request and receive data from a server in a flexible and efficient manner, enabling developers to build more efficient and powerful applications.
In traditional RESTful architectures, clients would have to make multiple requests to the server to retrieve data from different endpoints. This could result in over-fetching (receiving more data than needed) or under-fetching (not receiving enough data) and could lead to slow and inefficient application performance. GraphQL solves these problems by allowing clients to specify exactly what data they need and receive only that data in a single request.
GraphQL provides a strong typing system that defines the types of data that can be queried and returned by the server. This provides a clear understanding of the data schema and enables developers to build more robust and maintainable applications. Additionally, GraphQL supports introspection, allowing clients to query the schema itself and discover available types, fields, and queries.
Another advantage of GraphQL is its ability to support real-time data updates. Using subscriptions, clients can receive updates in real-time as soon as data changes on the server, without having to continually poll the server for updates.
GraphQL is a language-agnostic technology, which means that it can be used with any programming language and any database. This makes it a popular choice for building modern, scalable, and flexible APIs.

- Code-sharing
- Strongly typed
- Protocol, not a storage
- Introspective
- Latest version not required
Disadvantages of GraphQL
- GraphQL Query Complexity
- GraphQL Caching
- GraphQL Rate Limiting
