Running cs web proto against Coniql

Coniql (Github)[https://github.com/dls-controls/coniql]) is a prototype server that converts control system data (currently from PVAccess) into a GraphQL protocol that can be understood by cs-web-proto if it uses the Coniql plugin.

Set up Coniql

• Clone the coniql repo from the Github link above
• Run pipenv run python -m coniql.server

This will provide sim:// PVs only. To enable PVAccess PVs:

• set the EPICS7_BASE environment variable to the directory of an EPICS7 build
• pipenv install p4p

Now with pipenv run python -m coniql.server you should also see data from PVAccess PVs.

Load the ConiqlPlugin inside cs-web-proto

Edit App.tsx to load the ConiqlPlugin instead of the SimPlugin. The diff looks like this:
