A textual, Markdown-like notation for work breakdown structures with and/or decomposition — plus a live editor that renders it as a diagram.

- = mandatory sub-package (all of, side by side in the diagram) · | = alternative (any of, stacked) · […] = status · (M) = T-shirt effort · @name = responsibility · %% = comment.

Usage

Open the hosted editor — edit text on the left, the diagram is built live on the right. Toggles: transposed (narrow) layout, show discarded elements.

Jumping between diagram and text

Diagram and editor are linked in both directions:

• Alt+click a node (keyboard: Alt+Enter, touch: long press) selects its line in the text editor — collapsed editor panel opens first.
• Moving the cursor in the text highlights the matching node in the diagram.

A plain click keeps its old meaning: a node carrying a URL still opens it.

Loading a diagram from a URL

The editor can pull its notation text from an external text file via the sourceUrl query parameter — handy for sharing a plan or keeping the source in Git or a wiki:

https://mhoennig.github.io/werkbaum/?sourceUrl=https://raw.githubusercontent.com/mhoennig/werkbaum/main/docs/examples/example-plan-0.werkbaum

Ready-made examples in docs/examples/ — open them one after another, each becomes its own document, so afterwards you can switch between all of them in the editor title bar:

Example	Shows
▶ 0 · Online shop relaunch	a software project with all eight states
▶ 1 · New kitchen	a non-software plan, lots of alternatives — good for the cheapest-path toggle
▶ 2 · Community conference	a wide plan with many people; compare horizontal vs. compact
▶ 3 · Three workstreams	several roots = several trees side by side
▶ Werkbaum itself	what exists today and where it could go

(The links point at the latest build 🚧; the stable instance supports sourceUrl from its next production deploy on.)

The loaded text becomes its own document whose name is the URL, so your own documents stay untouched; the same link updates that one document instead of piling up copies. The URL is the source of truth — it is re-fetched on every load, so local edits to it do not survive a reload.

Notation files use the extension .werkbaum (UTF-8; see docs/SPEC.md §12 and D24) — a convention, not a contract: sourceUrl reads any text file over http(s) regardless of extension or content type.

Caveat — CORS: the browser only fetches a foreign host if it sends Access-Control-Allow-Origin. raw.githubusercontent.com and GitLab raw links do; an arbitrary web server often does not. If loading fails the previous content stays and a warning explains why. Only http/https are allowed.

Running it locally

The editor source now lives as ES modules under frontend/src/, bundled by Vite (see docs/DECISIONS.md D19). Because browsers block ES-module imports over file://, opening frontend/index.html directly no longer works — use one of:

cd frontend
npm install          # once
npm run dev          # dev server at http://localhost:8137
npm test             # Vitest unit tests
npm run build        # -> frontend/dist/index.html (single self-contained file)

The built dist/index.html inlines all JS, CSS and the favicon, so that file does open standalone via file:// and is what gets deployed.

Build hint & your own production install

Non-production builds carry a small hint next to the title (symbol + tooltip) so it's clear this is not the stable instance:

• Dev server (npm run dev) → 🔧 "Preview – local development build"
• Default build (npm run build, incl. the GitHub Pages deploy) → 🚧 "Latest build – may still be buggy"

For your own production install the hint is switched off:

cd frontend
npm ci                # or: npm install
npm run build:prod    # -> frontend/dist/index.html WITHOUT the hint

build:prod runs Vite in mode prod; frontend/.env.prod sets VITE_BUILD_BADGE=none, so the badge code is tree-shaken away entirely (it isn't even present in the output source). Drop the resulting dist/index.html onto your web space/server (standalone, file://-capable). Details: app.js (mountBuildBadge), docs/DECISIONS.md D16.

Two things otherwise handled only by the Pages workflow, to fix up yourself when self-hosting: the footer MIT-License link is relative to ../LICENSE (place that file one level above index.html, or adjust the link), and the version number stays the source placeholder 1.0 (the workflow otherwise replaces it from VERSION + commit count).

Easier: scripts/deploy-prod.sh. The script runs exactly that prod build and both fix-ups (drop LICENSE alongside + straighten the link, footer version + commit link just like the Pages workflow) and mirrors the result to a server via rsync/SSH:

scripts/deploy-prod.sh mih00@mih00.hostsharing.net:~/doms/werkbaum.javagil.de/htdocs-ssl

The target is either this argument or — with no argument — the DEPLOY_TARGET variable from the git-ignored file .env (template: .env.example, copy it once and fill in the path). An argument takes precedence.

Without -y it first shows a --dry-run preview and asks for confirmation. rsync --delete ensures nothing old is left at the target — so the target directory is treated as exclusive to Werkbaum (an in-flight Let's Encrypt challenge under .well-known/ is spared via --filter=protect, and web-friendly 755/644 permissions are enforced). (Hostsharing: a directly-served domain is served from …/htdocs-ssl/; as a subdomain under another domain the web directory would be …/subs-ssl/<name>/.)

Note: The detailed project documentation under docs/ is maintained in German, the project's source language (see CLAUDE.md). This README is available in English and German.

Deployment

The editor is published as a static page on GitHub Pages via GitHub Actions (workflow: .github/workflows/pages.yml). Triggered on every push to main and manually (workflow_dispatch).

The workflow sets up Node, runs npm ci, npm test (Vitest) and npm run build (Vite), then publishes the bundled frontend/dist/index.html as index.html at the root URL, plus LICENSE for the MIT link in the footer. The favicon is already inlined into the build, so nothing else needs copying; only the runtime ../LICENSE link is straightened on the copy. A failing test blocks the deploy. backend/ and the remaining docs/ are not published.

While assembling the site, the workflow also stamps the version into the footer: major.minor comes from the VERSION file (bumped by an explicit "bump commit"), and the micro part is the number of commits since that last bump — so it grows with every commit and resets to 0 right after a bump (Werkbaum 1.0.0, 1.0.1, … then bump VERSION to 1.1 → 1.1.0). Nothing is written back to the repo. In the footer the name Werkbaum links to the repository, while the version number links to that exact commit (…/commit/<sha>). Opened locally, the editor shows the source placeholder (Werkbaum 1.0).

One-time setup: In the repo settings under Pages, select Source = "GitHub Actions". The repo must be public for this (GitHub Pages via Actions is only available for private repos on a paid plan).
