Advantage of GraphQL
1. Efficient Data Fetching
- In GraphQL, clients have the ability to specify exactly the data they require, thereby avoiding the common problems of over-fetching and under–fetching that often arise with RESTful APIs. Customers can ask for only the information they require.
- This stops issues of too much data (over-fetching) or too little data (under-fetching) that often happen with RESTful APIs. Clients can request only the data they need, eliminating over-fetching and under-fetching issues common in RESTful APIs.
2. Declarative Data Queries
- When we need to access or analyze data, we can use a special language called a declarative query language. This language allows us to clearly explain what information we need without having to worry about the technical details of how to get it. we can express complex data requirements easily.
- People can tell what data they need with a special language. This makes it easy to explain complex data needs. Some sentences are short. Others are longer. There is variety in sentence length.
3. Strongly Typed Schema
- Using GraphQL APIs has many advantages for developers. The strongly typed schema acts as a clear blueprint, outlining the precise structure and data types for clients and servers.
- This helps eliminate confusion and ensures smooth communication between different parts of the application. Unlike traditional REST APIs, which can be ambiguous.
4. Grouping of Multiple Data Sources
- GraphQL is a technology that lets we bring together information from different places into one easy-to-use spot.
- It allows us to get all the data we need without having to go to multiple different places. GraphQL makes getting data simple.
5. Versioning and Evolution
- GraphQL structures can change over time without stopping current clients from working.
- This happens because GraphQL allows checking what fields are available. Developers can also slowly remove fields instead of removing them all at once.
6. Reduced Number of Endpoints
- When it comes to GraphQL, one of the major benefits is its simplicity in API management.
- This is because GraphQL exposes a single endpoint, which is in contrast to RESTful APIs that can have multiple endpoints.
Advantage & Disadvantage of GraphQL
GraphQL is a query language and runtime for APIs, designed to provide a more efficient and flexible way to fetch data compared to traditional REST APIs. With GraphQL, clients can request exactly the data they need, making APIs easier to use and reducing over-fetching and under-fetching of data.
