Usage

Basic Usage

node dist

Now the Channel Access is available to other clients through GraphQL.

note: before running the command above, a valid EPICS base installation needs to exist. EPICS_HOST_ARCH and EPICS_BASE need to be set as well. Otherwise a pre-compiled binary will be used, which will not be guaranteed to work on your system.

Recommended Usage

It is recommended to run the server as a container.

For example:

docker run -d onichandame/epics-proxy:latest
