#  [Graphene](http://graphene-python.org) [](https://travis-ci.org/graphql-python/graphene) [](https://badge.fury.io/py/graphene) [](https://coveralls.io/github/graphql-python/graphene?branch=master)
|
|
|
|
|
|
[Graphene](http://graphene-python.org) is a Python library for building GraphQL schemas/types fast and easily.
|
|
|
|
- **Easy to use:** Graphene helps you use GraphQL in Python without effort.
|
|
- **Relay:** Graphene has builtin support for Relay.
|
|
- **Data agnostic:** Graphene supports any kind of data source: SQL (Django, SQLAlchemy), NoSQL, custom Python objects, etc.
|
|
We believe that by providing a complete API you could plug Graphene anywhere your data lives and make your data available
|
|
through GraphQL.
|
|
|
|
|
|
## Integrations
|
|
|
|
Graphene has multiple integrations with different frameworks:
|
|
|
|
| integration | Package |
|
|
|---------------|-------------------|
|
|
| Django | [graphene-django](https://github.com/graphql-python/graphene-django/) |
|
|
| SQLAlchemy | [graphene-sqlalchemy](https://github.com/graphql-python/graphene-sqlalchemy/) |
|
|
| Google App Engine | [graphene-gae](https://github.com/graphql-python/graphene-gae/) |
|
|
| Peewee | *In progress* ([Tracking Issue](https://github.com/graphql-python/graphene/issues/289)) |
|
|
|
|
Also, Graphene is fully compatible with the GraphQL spec, working seamlessly with all GraphQL clients, such as [Relay](https://github.com/facebook/relay), [Apollo](https://github.com/apollographql/apollo-client) and [gql](https://github.com/graphql-python/gql).
|
|
|
|
## Installation
|
|
|
|
For instaling graphene, just run this command in your shell
|
|
|
|
```bash
|
|
pip install "graphene>=2.0"
|
|
```
|
|
|
|
## 2.0 Upgrade Guide
|
|
|
|
Please read [UPGRADE-v2.0.md](/UPGRADE-v2.0.md) to learn how to upgrade.
|
|
|
|
|
|
## Examples
|
|
|
|
Here is one example for you to get started:
|
|
|
|
```python
|
|
class Query(graphene.ObjectType):
|
|
hello = graphene.String(description='A typical hello world')
|
|
|
|
def resolve_hello(self, info):
|
|
return 'World'
|
|
|
|
schema = graphene.Schema(query=Query)
|
|
```
|
|
|
|
Then Querying `graphene.Schema` is as simple as:
|
|
|
|
```python
|
|
query = '''
|
|
query SayHello {
|
|
hello
|
|
}
|
|
'''
|
|
result = schema.execute(query)
|
|
```
|
|
|

|
|
After cloning this repo, ensure dependencies are installed by running:
|
|
|
|
```sh
|
|
pip install -e ".[test]"
|
|
```
|
|
|
|
After developing, the full test suite can be evaluated by running:
|
|
|
|
```sh
|
|
py.test graphene --cov=graphene --benchmark-skip # Use -v -s for verbose mode
|
|
```
|
|
|
|
You can also run the benchmarks with:
|
|
|
|
```sh
|
|
py.test graphene --benchmark-only
|
|
```

### Documentation
|
|
|
|
The documentation is generated using the excellent [Sphinx](http://www.sphinx-doc.org/) and a custom theme.
|
|
|
|
The documentation dependencies are installed by running:
|
|
|
|
```sh
|
|
cd docs
|
|
pip install -r requirements.txt
|
|
```
|
|
|
|
Then to produce a HTML version of the documentation:
|
|
|
|
```sh
|
|
make html
|
|
```
