# README | ||
Adopted and modified from : https://github.com/excitement-engineer/ktor-graphql | ||
|
||
## About | ||
This is a graphql backend for a small social networking app. | ||
|
||
## Data model | ||
Can be found in `schema.graphql` | ||
|
||
## Execution strategies | ||
For simplicity, we are using singletons to simulate our data access layers. | ||
In the real world, usage of dataloaders is recommended. Read more about that [here](https://www.graphql-java.com/documentation/v12/batching/) | ||
|
||
## Technical | ||
Although this example uses Ktor, any Kotlin server may be used. | ||
|
||
## Schema first vs code first | ||
This example is schema first, but there are also possibilities to write code-first resolvers | ||
(aka schema is defined by the code). Examples of code-first can be found [here](https://github.com/ExpediaDotCom/graphql-kotlin) |
