Great work, thanks for doing this. Really useful.
@kazuhitoyokoi - do you have a simple set of steps to create the nodegen fuction blocks? Or do I have to wade thru that info to create them?
The README.md in node-red-nodegen project has simple steps to create nodegen function nodes as follows.
## Installation * sudo npm install -g node-red-nodegen ### Create original node from function node * On Node-RED flow editor, save function node to library with file name (lower-case.js). * node-red-nodegen ~/.node-red/lib/function/lower-case.js * cd node-red-contrib-lower-case * sudo npm link * cd ~/.node-red * npm link node-red-contrib-lower-case * node-red -> You can use lower-case node on Node-RED flow editor.
You can also create "function node without vm module" using the following steps.
## Installation * git clone https://github.com/kazuhitoyokoi/node-red-nodegen.git * cd node-red-nodegen * git checkout master-functionwithoutvm * npm install ### Create original node from function node * On Node-RED flow editor, save function node to library with file name (lower-case.js). * node bin/node-red-nodegen.js ~/.node-red/lib/function/lower-case.js --name lower-case-wovm * cd node-red-contrib-lower-case-wovm * sudo npm link * cd ~/.node-red * npm link node-red-contrib-lower-case-wovm * node-red -> You can use lower-case-wovm node on Node-RED flow editor.
In the future, Node-RED flow editor will be able to have nodegen UI. Currently there is the design note about the UI.
I've just pushed a fix to git that restores the performance of the Switch node:
|Number of messages||Function Time (ms)||Switch Time (ms)|
This fix only applies if the node doesn't try to access context.
I suspect a similar performance regression will have been introduced to the Change node - I'll sort that out next.
Thank you for the optimization. I'll use the new version of Node-RED!
