# GraphQL Playground
![GraphQL Playground](../../../.gitbook/assets/graphql-playground%20%281%29.png)
***Attention:** For using the GraphQL Playground set `DEBUG=true` in your backend `.env`, see `.env.template`!*
To use GraphQL Playground, we need to know some basics:
## How To Login?
First, we need to have a user from ocelot.social to log in as.
The user can be created by seeding the Neo4j database from the backend or by multiple GraphQL mutations.
### Seed The Neo4j Database
In your browser you can reach the GraphQL Playground under `http://localhost:4000/`, if the database and the backend are running, see [backend](../../README.md).
There you will also find instructions on how to seed the database.
### Use GraphQL Mutations To Create A User
TODO: Describe how to create a user using GraphQL mutations!
### Login Via GraphQL
You can register a user by sending the query:
```gql
mutation {
login(email: "user@example.org", password: "1234")
}
```
Or use `"moderator@example.org"` or `"admin@example.org"` for the roll you need.
If all goes well, you will receive a QGL response like:
```json
{
"data": {
"login": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpZCI6InUzIiwibmFtZSI6Ikplbm55IFJvc3RvY2siLCJzbHVnIjoiamVubnktcm9zdG9jayIsImlhdCI6MTY2MjAyMzMwNSwiZXhwIjoxNzI1MTM4NTA1LCJhdWQiOiJodHRwOi8vbG9jYWxob3N0OjMwMDAiLCJpc3MiOiJodHRwOi8vbG9jYWxob3N0OjQwMDAiLCJzdWIiOiJ1MyJ9.atBS-SOeS784HPeFl_5s8sRWehEAU1BkgcOZFD8d4bU"
}
}
```
You can use this response to set an HTTP header when you click `HTTP HEADERS` in the footer.
Just set it with the login token you received in response:
```json
{
"Authorization": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpZCI6InUzIiwibmFtZSI6Ikplbm55IFJvc3RvY2siLCJzbHVnIjoiamVubnktcm9zdG9jayIsImlhdCI6MTY2MjAyMzMwNSwiZXhwIjoxNzI1MTM4NTA1LCJhdWQiOiJodHRwOi8vbG9jYWxob3N0OjMwMDAiLCJpc3MiOiJodHRwOi8vbG9jYWxob3N0OjQwMDAiLCJzdWIiOiJ1MyJ9.atBS-SOeS784HPeFl_5s8sRWehEAU1BkgcOZFD8d4bU"
}
```
This token is used for all other queries and mutations you send to the backend.
## Query And Mutate
When you are logged in and open a new playground tab by clicking "+", you can create a new group by sending the following mutation:
```gql
mutation {
CreateGroup(
# id: ""
name: "My Group"
# slug: ""
about: "We will save the world"
description: "<p class=\"\"><em>English:</em></p><p class=\"\">This group is hidden.</p><h3>What is our group for?</h3><p>This group was created to allow investigative journalists to share and collaborate.</p><h3>How does it work?</h3><p>Here you can internally share posts and comments about them.</p><p><br></p><p><em>Deutsch:</em></p><p class=\"\">Diese Gruppe ist verborgen.</p><h3>Wofür ist unsere Gruppe?</h3><p class=\"\">Diese Gruppe wurde geschaffen, um investigativen Journalisten den Austausch und die Zusammenarbeit zu ermöglichen.</p><h3>Wie funktioniert das?</h3><p class=\"\">Hier könnt ihr euch intern über Beiträge und Kommentare zu ihnen austauschen.</p>"
groupType: hidden
actionRadius: interplanetary
categoryIds: ["cat12"]
) {
id
name
slug
createdAt
updatedAt
disabled
deleted
about
description
groupType
actionRadius
myRole
}
}
```
You will receive the answer:
```json
{
"data": {
"CreateGroup": {
"id": "2e3bbadb-804b-4ebc-a673-2d7c7f05e827",
"name": "My Group",
"slug": "my-group",
"createdAt": "2022-09-01T09:44:47.969Z",
"updatedAt": "2022-09-01T09:44:47.969Z",
"disabled": false,
"deleted": false,
"about": "We will save the world",
"description": "<p class=\"\"><em>English:</em></p><p class=\"\">This group is hidden.</p><h3>What is our group for?</h3><p>This group was created to allow investigative journalists to share and collaborate.</p><h3>How does it work?</h3><p>Here you can internally share posts and comments about them.</p><p><br></p><p><em>Deutsch:</em></p><p class=\"\">Diese Gruppe ist verborgen.</p><h3>Wofür ist unsere Gruppe?</h3><p class=\"\">Diese Gruppe wurde geschaffen, um investigativen Journalisten den Austausch und die Zusammenarbeit zu ermöglichen.</p><h3>Wie funktioniert das?</h3><p class=\"\">Hier könnt ihr euch intern über Beiträge und Kommentare zu ihnen austauschen.</p>",
"groupType": "hidden",
"actionRadius": "interplanetary",
"myRole": "owner"
}
}
}
```
If you look into the Neo4j database with your browser and search the groups, you will now also find your new group.
