Portfolio

Portfolio is a ClojureScript "visual REPL" — it renders UI components in named, isolated scenes so you can see every component state at a glance. It is similar to Storybook.js but designed for REPL-driven ClojureScript development.

Current release: no.cjohansen/portfolio {:mvn/version "2026.03.1"}

Quick Decision: What do you need?

Task	Go to
Install, start the UI, shadow-cljs setup	setup.md
Define scenes with defscene, params, atoms, lifecycle	defscene.md
Choose a framework adapter (Reagent, React, Replicant…)	defscene.md
Organize scenes into collections, folders, packages	organization.md
Customize background, viewport, grid, CSS, HTML	customize-ui.md
Use tap> from the REPL without defining a scene	setup.md
Disable Portfolio in production builds	setup.md
Common mistakes and things to avoid	anti-patterns.md

Core Mental Model

Portfolio renders scenes — named snapshots of a component in a specific state. Scenes live in regular ClojureScript namespaces (typically named *-scenes), and Portfolio automatically organizes them into a navigable sidebar by namespace hierarchy.

defscene → scene → namespace (package) → folder → sidebar

The UI runs in the browser at your dev server address. Re-evaluating a defscene at the REPL re-renders it immediately — no page refresh needed.

Minimal Working Example

;; deps.edn
{:deps {no.cjohansen/portfolio {:mvn/version "2026.03.1"}}}

;; src/my/button_scenes.cljs
(ns my.button-scenes
  (:require [portfolio.reagent :refer-macros [defscene]]))

(defscene default-button
  [:button.btn "Click me"])

(defscene disabled-button
  [:button.btn {:disabled true} "Can't click"])

;; src/my/dev/portfolio.cljs  — call this from your shadow-cljs :runner-ns
(ns my.dev.portfolio
  (:require [portfolio.ui :as ui]))

(ui/start! {:config {:css-paths ["/css/app.css"]}})

shadow-cljs :portfolio Build Target

Auto-loads every namespace whose name ends in -scenes. The fastest setup path:

;; shadow-cljs.edn
{:deps {:aliases [:dev]}
 :dev-http {8080 ["dev-resources/public" "classpath:public"]}
 :builds
 {:portfolio
  {:target :portfolio
   :runner-ns my.dev.portfolio    ;; omit to start with no config
   :dev {:output-dir "dev-resources/public/js"}}}}

"classpath:public" in :dev-http is required — it serves Portfolio's bundled assets from the jar.

Default Advice

• Keep scenes in a dedicated directory (dev/, scenes/, or a :dev alias source path) so they are never included in production builds.
• Use :params whenever the component data is non-trivial — it enables REPL tinkering and search indexing.
• Prefer the :portfolio shadow-cljs target over manual namespace loading for new projects.
• Do not suppress Portfolio in production via compiler flags if you can simply exclude scene namespaces from the production build instead.
