## Spring Boot Graphql
|
||||
|
||||
This module contains articles about Spring Boot Graphql
|
||||
|
||||
### The Course
|
||||
The "REST With Spring" Classes: http://bit.ly/restwithspring
|
||||
|
||||
### Relevant Articles:
|
||||
|
||||
- [Getting Started with GraphQL and Spring Boot](https://www.baeldung.com/spring-graphql)
|
||||
- [Expose GraphQL Field with Different Name](https://www.baeldung.com/graphql-field-name)
|
||||
|
||||
### GraphQL sample queries
|
||||
|
||||
Query
|
||||
```shell script
|
||||
curl \
|
||||
--request POST 'localhost:8080/graphql' \
|
||||
--header 'Content-Type: application/json' \
|
||||
--data-raw '{"query":"query {\n recentPosts(count: 2, offset: 0) {\n id\n title\n author {\n id\n posts {\n id\n }\n }\n }\n}"}'
|
||||
```
|
||||
|
||||
Mutation
|
||||
```shell script
|
||||
curl \
|
||||
--request POST 'localhost:8080/graphql' \
|
||||
--header 'Content-Type: application/json' \
|
||||
--data-raw '{"query":"mutation {\n createPost(title: \"New Title\", authorId: \"Author2\", text: \"New Text\") {\n id\n category\n author {\n id\n name\n }\n }\n}"}'
