Graphene is a Python library for building GraphQL schemas/types fast and easily.
* **Easy to use:** It maps the models/fields to internal GraphQL objects without effort.
* **Relay:** Graphene has builtin support for Relay
* **Django:** Automatic *Django model* mapping to Graphene Types. *See an [example Django](http://github.com/graphql-python/swapi-graphene) implementation*
## Installation
For instaling graphene, just run this command in your shell
```bash
pip install graphene
```
## Examples
Here is one example for get you started:
```python
class Query(graphene.ObjectType):
hello = graphene.StringField(description='A typical hello world')
ping = graphene.StringField(description='Ping someone',
to=graphene.Argument(graphene.String))
def resolve_hello(self, args, info):
return 'World'
def resolve_ping(self, args, info):
return 'Pinging {}'.format(args.get('to'))
schema = graphene.Schema(query=Query)
```
Then Querying `graphene.Schema` is as simple as:
```python
query = '''
query SayHello {
hello
ping(to:'peter')
}
'''
result = schema.execute(query)
```
