# GraphQL server example
This is a simple GraphQL server example using [graphql-yoga](https://github.com/prisma-labs/graphql-yoga), [Mongoose](https://www.npmjs.com/package/mongoose) and MongoDB.
To start the server:
- start MongoDB on your local machine
- `npm run start`
Go to [http://localhost:3000/playground](http://localhost:3000/playground) to launch the GraphQL Playground.
# Queries
**All sensors:**
```graphql
{
sensors {
sensorName
type
location
_id
}
}
```
**All sensorValues:**
```graphql
{
sensorValues {
temp
humidity
time
_id
sensor {
sensorName
type
location
_id
}
}
}
```
**A sensor:**
```graphql
{
sensor(_id: "5eba09502ba39cfe8fd331cd") {
sensorName
type
location
_id
}
}
```
**A sensorValue:**
```graphql
{
sensorValue(_id: "5ebb20231b0fc015e75c0e0f") {
temp
humidity
time
_id
sensor {
sensorName
type
location
_id
}
}
}
```
## Mutations
**Create a sensor:**
```graphql
mutation {
createSensor(
sensorName: "Freezer Sensor 1"
