graphql-mode is an emacs mode to edit GraphQL schema and queries.
graphql-mode can be installed from MELPA repository at http://melpa.org/.
Once the installation is completed, any file with a .graphql extension will be loaded with this mode.
You can optionally install json-mode, and it will be enabled in the
buffer that contains the response from a GraphQL service.
To send a query to a server, you will first need the
request package. Then use
graphql-send-query (C-c C-c) to send a query.
If you have a .graphqlconfig file, you can select an endpoint configuration
with graphql-select-endpoint (C-c C-l).
To send additional headers for a request, graphql-extra-headers must be
set. It is automatically set by graphql-select-endpoint, or you can edit its
value using JSON with graphql-edit-headers (C-c e h).
