My purpose was to run Lumo directly with Node.js , then people like me who is more familiar with Node.js can use
node --inspect to use DevTools to find slow functions.
According to @anmonteiro90 that usage of Lumo is already supported. The thing to do is to compile with
boot dev, which looks like:
(deftask dev  (comp (check-node-modules) (watch) (speak) (compile-cljs) (sift-cljs-resources) (cache-edn->transit) (write-core-analysis-caches) (target) (bundle-js :dev true)))
Make sure you have run
yarn to get the latest dependencies. Then
yarn dev will be okay, which is an alias for:
node target/bundle.js -k lumo-cache -c target
-k refers “cache”,
-c refers to “classpath”. So for my case, I can run with this command:
node --inspect target/bundle.js
It will generate an URL for Chrome to open the DevTools. to start with the most simple commands.
I tried, the Profiler in DevTools worked. Cheers.
