nREPL

If you would like to send every REPL eval to Portal, you can use the portal.nrepl/wrap-portal nrepl middleware.

Note You will also need to invoke (add-tap portal.api/submit) for eval results to show up in portal.

The main advantage of using this middleware is that it can capture additional information about your REPL interaction, such as:

• Source and file info
• Runtime type (very handy for cljc files)
• Timings
• Test assertion output
• Eval exceptions
• Stdio

Note Portal will keep all evaluated objects from being garbage collected until they are cleared from the UI. However, the nREPL middleware will only submit values to Portal when the UI is open.

tools.deps

If you are starting nrepl from tools.deps, you can try the following:

;; deps.edn
{:aliases
 {:nrepl
  {:extra-deps {cider/cider-nrepl {:mvn/version "0.28.5"}}
   :main-opts ["-m" "nrepl.cmdline"
               "--middleware"
               "[cider.nrepl/cider-middleware,portal.nrepl/wrap-portal]"]}}}

shadow-cljs

If you are using shadow-cljs, you can add the middleware via the shadow-cljs.edn file:

;; shadow-cljs.edn
{:nrepl {:middleware [portal.nrepl/wrap-portal]}}
