Portal - navigate your data

New Project

Portal is a new project so things may change rapidly, please see the djblue/portal repository for the latest information

Portal is a new project that allows exploration of Clojure data, using a browser window to visualise and inspect Clojure, JSON and Transit data.

Portal - explore your Clojure data

Portal as a deps.edn alias

practicalli/clojure-deps-edn contains the :inspect/portal alias that run a Reveal repl with data browser.

  • inspect/portal-cli - Clojure CLI (simplest approach)
  • inspect/portal-web - Web ClojureScript REPL
  • inspect/portal-node - node ClojureScript REPL

Run a REPL with Portal dependencies

Run a REPL in a terminal and include the Portal library, using the Clojure CLI tools

clojure -M:inspect/portal-cli

Starting Portal in the REPL

(require '[portal.api :as portal]) once the REPL starts. For inspector-portal-web use (require '[portal.web :as portal]) instead

(portal/open) to open the web based inspector window in a browser.

(portal/tap)to add portal as a tap target (add-tap)

Starting Portal on REPL startup

Start the Portal inspector as soon as the REPL is started. This works for a terminal REPL as well as clojure aware editors.

Create a dev/user.clj source code file which requires the portal.api library, opens the inspector window and adds portal as a tap source.

(ns user
  (:require [portal.api :as inspect]))

;; Start Portal inspector on REPL start

;; Open a portal inspector window

;; Add portal as a tap> target

  ;; Clear all values in the portal inspector window

  ;; Close the inspector

  ) ;; End of rich comment block

The rich comment block includes commands to clear and close the portal inspector window.

Start a REPL using the :env/dev and :inspect/portal-cli aliases from practicalli/clojure-deps-edn, using the command:

clojure -M:env/dev:inspect/portal-cli

To use this with Emacs CIDER editor, create a .dir-locals.el file in the root of the Clojure project with the following configuration

((clojure-mode . ((cider-clojure-cli-global-options . "-M:env/dev:inspect/portal-cli"))))

Using Portal to inspect data

The tap> function sends data to Portal to be shown on the inspector window.

(tap> {:accounts [{:name "jen" :email "jen@jen.com"} {:name "sara" :email "sara@sara.com"}]}) to send data to the portal inspector window (or any other data you wish to send)

Use portal to navigate and inspect the details of the data sent to it via tap>.

(portal/clear) to clear all values from the portal inspector window.

Close Portal

(portal/close) to close the inspector window.
