Is there an event which is raised when node-red finished deploying?

windkh · 4 July 2021 15:52

I searched the forum but could not find anything that could solve my problem:

Use Case:
I would like to do execute some code after all nodes in one of my libs were successfully initialized. All my nodes register themselves in a list and when the list
is complete I want to to some checks and so on...

Question:
Is there an event which is raised by node-red when the flows are fully deployed?

There is a flows:started event - but that is when the flows have all been told to start. Some nodes may do asynchronous work (eg connect to a remote database - or not) - so we can never be sure when something is "fully deployed".

Ah thanks for the hint. That would be completely ok as no async stuff is used in my use case.

There is also the "runtime-event" with an ID of "runtime-state". Though this appears to trigger twice.

I've just used it in uibuilder v4-beta to move the block of log information for uibuilder to a better place and only triggered after some other events have completed. I put a simple switch in place to only run it once:

github.com

TotallyInformation/node-red-contrib-uibuilder/blob/main/nodes/uibuilder.js#L150-L175

    
      
          // When uibuilder enters runtime state, show the details in the log
          let initialised = false
          RED.events.on('runtime-event', function(event) {
              if (event.id === 'runtime-state' && initialised === false ) {
                  initialised = true
                  RED.log.info('+-----------------------------------------------------')
                  RED.log.info(`| ${uib.moduleName} v${uib.version} initialised`)
                  RED.log.info(`| root folder: ${uib.rootFolder}`)
                  if ( uib.customServer.port ) {
                      RED.log.info(`| Using custom ExpressJS webserver at:`)
                  } else {
                      RED.log.info('| Using Node-RED\'s webserver at:')
                  }
                  RED.log.info(`|   ${uib.customServer.type}://${uib.customServer.host}:${uib.customServer.port}/ or ${uib.customServer.type}://localhost:${uib.customServer.port}/`)
                  RED.log.info(`| Installed packages:`)
                  const pkgs = Object.keys(uib.installedPackages)
                  for (let i = 0; i < pkgs.length; i=i+4) {
                      const k = []
                      for (let j = 0; j <= 3; j++) {
                          if ( pkgs[i+j] ) k.push(pkgs[i+j])
