@knolleary Node-RED Flow Debugger ● Set breakpoints on node ports ● Pause runtime or individual nodes when triggered ● Show queued messages ● Allow step-by-step execution of the flow npm install node-red-debugger 

@knolleary RED.hooks API ● Hooks API lets plugins add custom code to the message path at certain key points ● Also available for the Node Install path - useful for integrating build tools like electron-build 

@knolleary Node-RED Flow Linter ● Checks the flow for potential problems ● Rule can be customised to personal preference ● New rules can be added via additional plugins ● Runs on the command-line or integrated in the editor npm install nrlint 

@knolleary ● Simply way to package and share custom Node-RED editor themes ● Install a theme plugin then make a one-line change in your settings file to enabled it ● Some great community-created themes available Node-RED Theme Plugins npm install @node-red-contrib-themes/theme-collection 

@knolleary ● Add new library sources to the Import/Export dialog ● Use the File Store plugin to create additional libraries on the local file-system ● Combine with a file-sharing utility, such as Dropbox, and create an easy way to share flows with teammates. Node-RED Library Store Plugins npm install @node-red/library-file-store

@knolleary ● Still being developed - not for general use yet ● Runs a series of checks against a node - either locally or on npm - to ensure it follows best practices ● Looks at package and node naming, licensing, git repository (if provided), example flows and more ● Provides a report back - either as text or JSON ● Will generate a scorecard for use on flows.nodered.org node-red-dev CLI for node developers coming soon 

@knolleary ● Create tests for your flows within the editor ● Testing Sidebar lets you define test suites and test cases ● Individual node behaviour can then be customised per-test case, letting you simulate different behaviours - for example, faking the response of an HTTP Request to test edge cases ● Run tests from the sidebar, or on the command-line Node-RED Flow Testing Framework coming soon-ish Initial design sketches from January 2020
