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.

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.
