kirjava is a lightweight Python GraphQL client.

Making Queries with a Client

GraphQL services are interacted with using a Client object:

>>> import kirjava
>>> client = kirjava.Client("https://api.coolsite.com/")

The client is associated with a particular URL upon creation.

Queries are then made using the execute method.

>>> client.execute("{ me { name email }}")
{'data': {'me': {'name': 'Jon Snow', 'email': 'jon@winterfell.gov.ws'}}}

If authentication tokens need to be added, they can be inserted into the headers:

>>> client.headers["Authorization"] = "dani123"

Variables can be passed along with the query:

>>> client.execute("{ me { name email }}", variables={"var1": 123})

You can see all previous queries made by a client:

>>> client.history
(({'string': { me { name email }}, 'variables': {'var1': 123}, {'data': {'me
': {'name': 'Jon Snow', 'email': 'jon@winterfell.gov.ws'}}}), ({'string': {
me { name email }}, 'variables': {}}, {'data': {'me': {'name': 'Jon Snow', '
email': 'jon@winterfell.gov.ws'}}}))

Clients use requests sessions internally, and you can access any cookies set by the server via client.session.cookies.

Uploading Files

If you want to upload files as part of your request, kirjava can do this. Just add them as a variable:

>>> mutation = "mutation sendFile($file: Upload) {sendFile(file: $file) { success }}"
>>> f = open("local_file.txt", "rb"):
>>> response = client.execute(mutation, variables={"file": f})
>>> f.close()

kirjava does this by implementing the GraphQL multipart request specification under the hood, and using this if any of the variables supplied are Python file objects.

Note that the GraphQL server on the other end must be set up to process multipart requests.

Making Queries without a Client

Alternatively, if creating a dedicated Client object is somehow beneath you, and you just want to fire off a quick request without any of that overhead, there is a module level execute() function:

>>> kirjava.execute("https://api.coolsite.com/", "{ me { name email }}", headers={"Authorization": "dani123"}, variables={"var1": 123})
