Run

Run with the Flask built-in server for the development. (Deployment options for proudction are descriped in the Flask documentation.)

flask run

The above command starts the built-in server that only allows accress from localhost. It starts the server at the default TCP port, usually 5000.

To allow the access from outside, use --host=0.0.0.0 option. The TCP port can be specified by --port option. For example:

flask run --host=0.0.0.0 --port=5000

Access to the server with cURL

Now, you can send GraphQL requests to the server, for example, as follows.

curl -d "query={allMaps { edges { node { name mapper } } }}" localhost:5000/graphql

Access to the server with a web browser

If you access to the server with a web browser, it will show a graphical user interface GraphiQL: http://localhost:5000/graphql
