Runtime to be used with the noflo fbp protocol:
Usage: fbpx-server [options] <file ...> Options: -h, --help output usage information -V, --version output the version number -t, --type [name] Runtime type chix, noflo-nodejs -c, --cache cache components -p, --proxy expose /proxy to proxy requests to e.g. a browser -s, --secure secure wss or ws -u, --uppercase force ports uppercase -h, --host [name] hostname -p, --port [name] port -I, --no-ids do not use uuids -b, --bail bail on errors -i, --interface [name] choose a webserver interface -l, --loader [loader] loader `remote` or `npm` -L, --loglevel [level] Log level -f, --flowhub ping flowhub -v, --verbose verbose output
The transport will be independend from the protocol itself.
It's job is:
- keep track of client scope.
For the noflo protocol, the scope are graphs.
The monitors will listen for output from whatever it listen to.
They only know how to sendAll(), sendAll is a negotiating method within
the transport. This method will determine who is concidered to be
This will mainly depend on what is considered the scope parameter.
Handlers will handle the received requests. Sometimes they will need to send data back to the requester, sometimes they will not send any data back.
The requester will then receive it's reply as part of the group who is
subscribed to the
particular scope. Which is a graph in the context of this protocol.
Implementation of the above.
There are three variants for now:
- receive / send
The schema defines when a property is considered to be a topic.
In this case,
graph will always be defined as topic.
This can then be used within the transport to categorize the clients. sendAll will then be aware of who it is it must send its reply to.
To run the chix-runtime and be able to use the UI at https://app.flowhub.com
You must first register.
npm run register
Above will generate a flowhub.json file, you must modify this file to contain your flowhub userID
In order to connect with flowhub the server must be started in secure mode. A simple way to do this is to run the script `create_cert.sh'
After this you must run the server in secure mode:
fbpx-server main_graph.fbp --flowhub --secure -L debug
First generate a certificate.
If the connection is not trusted, first go to the url with a browser and accept the self signed certificate, otherwise the connection will silently fail with a 500 message.
To update the modified yaml schemas run:
npm run schemas
This will update ./schemas.js in the root directory
