Agenda

11. 11
● GraphQL is an open-source query language for Rest API's and it is developed by Facebook in
2012 before releasing publicly in 2015.
● GraphQL provides an easy-to-use interface to query data from different sources in a single
API call.
● It's a query language that lets you write queries using an object structure rather than a text
string.
● It allows you to send the query to your API and get the required data.
What is GraphQL

Why GraphQL

13. 13
● Enables the use of multiple endpoints
● Prevents over-fetching data
● Simple versioning
● Easily access (relational) data
● Integration
● Strongly-typed schema
● Saves time and bandwidth
● Provides abstraction which reduces complexity
Challenges addressed by GraphQL

14. Example
14

15. Case One: User Rest API that returns 10 fields in response but client A
requires only 5 fields and client B requires only 3 fields in response
15

16. Case two: We have to fetch data from multiple rest API's and each
APIs will respond with JSON payload. GraphQL will aggregate all the
responses and send back the required data to the client.
