NodeJS Server Input
NodeJS Server Input tasks are used to receive HTTP requests and to send replies to the servers from
which the requests were made.
Essentially this task does the same as the HTTP Server Input task, but it uses a NodeJS Server (ver-
sion 12.13.1, installed by Workflow) instead of Workflow's custom server component. The NodeJS
Server is more secure, more up to date and more standardized.
For instance:
l
PUT and DELETE actions can be posted to the server.
l
The NodeJS Server can serve multiple static resources at once.
l
Port numbers > 9999 are allowed.
l
You can specify a HTTPS port separately.
l
A Proxy list can be used to setup end points for redirecting requests to another server. This could
be useful if for example the Connect server is on another server which could change; when it
changes you’d only have to modify the proxy list instead of the configuration.
l
You can enable or disable authentication using users from an Active Directory server.
The NodeJS Server is only started automatically by Workflow when NodeJS input plugins are detected
in the configuration. If no NodeJS input plugins are present, the service ("ppNode") is not started by
Workflow; it can still be started manually, but will only serve static resources and redirect requests to
other servers.
Note: The NodeJS Server installed with Workflow is not supported in an x86 environment.
