### 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}"}'
