# All the Databases
A GraphQL server tutorial combining 5 data sources:
https://www.compose.com/articles/use-all-the-databases-part-1/
To follow along, check out the [`empty-resolvers` branch](https://github.com/GraphQLGuide/all-the-databases/tree/empty-resolvers).
Code written in the tutorial can be found in:
- [server.js](https://github.com/GraphQLGuide/all-the-databases/blob/master/server.js)
- [data/schema.js](https://github.com/GraphQLGuide/all-the-databases/blob/master/data/schema.js)
- [data/resolvers.js](https://github.com/GraphQLGuide/all-the-databases/blob/master/data/resolvers.js)
There's also database, ORM, and seeding code in [data/connectors.js](https://github.com/GraphQLGuide/all-the-databases/blob/master/data/connectors.js).
## Browse data
Here's the deployed version of this server:
[all-the-databases.graphql.guide/graphiql](https://all-the-databases.graphql.guide/graphiql)
Now [try out a query](#query)
## Run locally
Get the code:
```sh
git clone git@github.com:GraphQLGuide/all-the-databases.git
cd all-the-databases
npm install
```
Get the databases:
```
brew install redis
brew install elasticsearch
brew install mongodb
```
Run one command per terminal tab:
```
mongod
```
```
redis-server /usr/local/etc/redis.conf
```
```
elasticsearch
```
Then in the `all-the-databases/` directory, run the GraphQL server:
```
npm run dev
```
Then open:
[localhost:8080/graphiql](http://localhost:8080/graphiql)
Then query:
## Query
When you paste this on the left side of the GraphiQL page:
```
{
user(id: 1) {
firstName
lastName
photo
mentions {
...TweetDetails
}
}
publicFeed {
...TweetDetails
}
cityFeed {
...TweetDetails
}
}
fragment TweetDetails on Tweet {
text
author {
firstName
lastName
photo
}
city
views
created
}
```
and hit the play button (or `cmd-return`), then you should get something like this on the right:
```json
