The portal UI can be used to inspect values of various shapes and sizes. The UX will probably evolve over time and user feedback is welcome!

For an in-depth explanation of the UI, you can jump to the UI docs.


To get an overview of the Portal UI and workflow, checkout the following recording of a live demo I gave for London Clojurians.

More video presentations on Portal can be found here.


To start a repl with portal, run the clojure >= 1.10.0 cli with:

clj -Sdeps '{:deps {djblue/portal {:mvn/version "0.57.0"}}}'

or for a web clojurescript >= 1.10.773 repl, do:

clj -Sdeps '{:deps {djblue/portal {:mvn/version "0.57.0"}
                    org.clojure/clojurescript {:mvn/version "1.10.844"}}}' \
    -m cljs.main

or for a node clojurescript >= 1.10.773 repl, do:

clj -Sdeps '{:deps {djblue/portal {:mvn/version "0.57.0"}
                    org.clojure/clojurescript {:mvn/version "1.10.844"}}}' \
    -m cljs.main -re node

or for a babashka >=0.2.4 repl, do:

bb -Sdeps '{:deps {djblue/portal {:mvn/version "0.57.0"}}}'

or for a lein project.clj, add:

{:profiles {:dev {:dependencies [[djblue/portal "0.57.0"]]}}}

or as a global profile, add to ~/.lein/profiles.clj:

{:portal {:dependencies [[djblue/portal "0.57.0"]]}}

Note If you add Portal to a profile other than :dev, when starting a REPL start it with with-profiles +portal. The + is important.

or for Clojure CLR, checkout this example project,

or for examples on how to integrate portal into an existing project, look through the examples directory.

Note Portal can also be used without a runtime via the standalone version.


Try the portal api with the following commands:

;; for node and jvm
(require '[portal.api :as p])

;; for web
;; NOTE: you might need to enable popups for the portal ui to work in the
;; browser.
(require '[portal.web :as p])

(def p (p/open)) ; Open a new inspector

;; or with an extension installed, do:
(def p (p/open {:launcher :vs-code}))  ; jvm / node only
(def p (p/open {:launcher :intellij})) ; jvm / node only

(add-tap #'p/submit) ; Add portal as a tap> target

(tap> :hello) ; Start tapping out values

(p/clear) ; Clear all values

(tap> :world) ; Tap out more values

(prn @p) ; bring selected value back into repl

(remove-tap #'p/submit) ; Remove portal from tap> targetset

(p/close) ; Close the inspector when done

(p/docs) ; View docs locally via Portal - jvm / node only

Warning Portal will keep objects from being garbage collected until they are cleared from the UI.
