# add·ideas Toolbox Portal `toolbox-portal` is the static launcher and release assembler for the add·ideas browser toolbox. Version `0.2.21` reads one same-origin catalogue, shows each app as a compact launch tile, and keeps personal pins, drag-and-drop ordering, visibility, and appearance in the current browser. Pinned tools have their own section; search, category, and clickable tag filters stay close to the tool list. The v1 boundary is intentionally small: - apps remain separately versioned and released repositories; - `@add-ideas/toolbox-contract` owns manifest, catalogue, and URL validation; - the portal navigates to apps—there are no iframes, plugins, remote modules, or runtime-loaded application code; - the assembler copies already-built, exact ZIP artifacts and never builds app source or resolves a `latest` release. ## Development Requirements: Node.js 22 or newer and npm 11 or newer. The committed `.npmrc` selects the public, token-free package scope on Gitea; registry credentials are not required to install the Toolbox SDK packages. Install and verify the portal: ```sh npm ci npm test npm run lint npm run build npm run dev ``` The package lock resolves the `^0.2.3` SDK ranges to the published `0.2.3` packages. A sibling SDK checkout is only needed when intentionally developing the SDK and portal together. Vite uses `base: './'`, so the built portal works at `/` or a nested static path. The development catalogue at `public/toolbox.catalog.json` points to assembled paths (`./apps/pdf/`, `./apps/xslt/`, `./apps/onenote/`, `./apps/av/`, `./apps/regex/`, `./apps/svg/`, `./apps/auth/`, `./apps/sudoku/`, `./apps/colour/`, `./apps/office/`, `./apps/image/`, `./apps/file/`, `./apps/epub/`, `./apps/archive/`, `./apps/privacy/`, `./apps/crypto/`, `./apps/barcode/`, `./apps/network/`, `./apps/geo/`, `./apps/helper/`, `./apps/rand/`, `./apps/data/`, `./apps/diff/`, `./apps/time/`, `./apps/text/`, and `./apps/unicode/`). Those manifests will correctly appear as unavailable until an assembled release is being served. ## Catalogue and launches The portal fetches `./toolbox.catalog.json`, validates it with the shared contract, and then validates each enabled manifest. A bad individual manifest is reported without hiding valid apps; a bad or unreachable catalogue gets a retry state. An empty valid catalogue gets its own empty state. Internal launch links stay same-origin and receive the exact catalogue URL in a `toolbox` query parameter. For example: ```text /apps/pdf/?toolbox=https%3A%2F%2Ftoolbox.example%2Ftoolbox.catalog.json ``` Apps discover that context through the shared shell/contract and retain their standalone fallback when no context is present. External catalogue entries open according to their declared launch mode and do not receive toolbox context. Personal settings use the namespaced local-storage key `@add-ideas/toolbox-portal:v1:preferences`. The preferences panel can reset, export, and import the versioned JSON document. The portal itself does not transmit preferences. Because Toolbox apps share an origin, code explicitly trusted in an app can access same-origin browser storage; review each app's privacy and executable-code warning. Light, dark, and system modes are supported. ## Production deployment behind Traefik The committed `compose.yaml` is the shortest production path. Its release container downloads the immutable Toolbox 0.18.1 ZIP during the image build, verifies SHA-256 before extracting it, and then copies only the verified static files into the pinned unprivileged nginx image. Node.js and a local portal assembly are not required on the deployment host. Prerequisites: - Docker with the Compose plugin; - Traefik attached to the existing external Docker network `internal`; - Traefik HTTP and HTTPS entrypoints named `web` and `websecure`; - a certificate resolver named `netcup`; - DNS for `toolbox.add-ideas.de` and `auth.toolbox.add-ideas.de` pointing to that Traefik instance; and - outbound HTTPS access to `git.add-ideas.de` while the image is built. Deploy a fresh clone with: ```sh git clone https://git.add-ideas.de/lotobo/toolbox-portal.git cd toolbox-portal docker compose up -d --build docker compose ps ``` No host port is published. Traefik permanently redirects `http://toolbox.add-ideas.de` to HTTPS, routes `https://toolbox.add-ideas.de` to nginx on the shared network at port 8080, and obtains its TLS certificate through `netcup`. The hostname, network, resolver, release version, and matching checksum can be overridden through environment variables; copy `.env.example` to `.env` only when an override is needed. For example, set `TOOLBOX_HOST=staging.toolbox.add-ideas.de` for a staging host. The same container also exposes only the packaged authentication app at `https://auth.toolbox.add-ideas.de/`. Traefik adds the internal `/apps/auth` prefix while the public URL remains `/`, so assets remain relative and the browser binds WebAuthn credentials to the dedicated `auth.toolbox.add-ideas.de` RP ID. The main Toolbox copy at `/apps/auth/` remains useful for offline inspection but disables live ceremonies because all Portal apps share that origin. The router hostname can be overridden with `AUTH_TOOLS_HOST`, but the bundled Auth Tools release enables live ceremonies only on its pinned production host (or localhost); other hosts remain inspect-only. A different production host therefore also requires rebuilding Auth Tools with the new exact host. Never widen the RP ID to `add-ideas.de`. The external network is deliberately not created by this project. Creating a private project-local network would prevent an independently managed Traefik container from reaching the service. ## Exact release assembly Every app release ZIP must put these items at its archive root: ```text index.html (or the entry declared by toolbox-app.json) toolbox-app.json CHANGELOG.md LICENSES/ SOURCE.md ...built static assets ``` The app release should also publish a matching `.sha256` sidecar. The manifest must declare the pinned reverse-DNS id and version. Application and portal versions are independent. `release/toolbox.lock.json` is the reviewed Toolbox v0.18.1 / Portal v0.2.21 lock. Its URLs and checksums pin the published PDF Tools 0.4.4, XSLT Tools 0.4.3, OneNote Tools 0.3.4, Audio & Video Tools 0.3.0, Regex Tools 0.4.2, SVG Tools 0.1.0, OTP & Passkey Tools 0.3.0, Sudoku Tools 0.2.1, Colour Tools 0.1.0, Office Tools 0.1.0, and the initial 0.1.0 releases of Image, File, EPUB, Archive, Privacy, Crypto, Barcode, Network, Geo, Helper, Random, Data, Diff, Time, Text, and Unicode Tools. Use `release/toolbox.lock.example.json` as the template for a future release and verify every downloaded asset before committing updated values. Artifacts may be: - a path relative to the lock file; - a `file:` URL; or - a credential-free HTTPS URL to an immutable release asset. For a private Gitea release, download the exact asset first and put its local path in the lock. Do not put credentials in a lock URL. Build the portal and assemble the distribution: ```sh npm ci npm test npm run build npm run assemble -- \ --lock release/toolbox.lock.json \ --portal-dist dist \ --output build/toolbox \ --archive build/add-ideas-toolbox-0.18.1.zip ``` Existing output is refused. Pass `--force` only when replacing those exact paths is intended. A successful run produces: ```text build/toolbox/ ├── index.html ├── toolbox.catalog.json generated from the lock ├── toolbox.release.json ids, versions, targets, checksums ├── LICENSE.txt ├── SOURCE.md ├── THIRD_PARTY_LICENSES.txt ├── THIRD_PARTY_NOTICES.md └── apps/ ├── pdf/ ├── xslt/ ├── onenote/ ├── av/ ├── regex/ ├── svg/ ├── auth/ ├── sudoku/ ├── colour/ ├── office/ ├── image/ ├── file/ ├── epub/ ├── archive/ ├── privacy/ ├── crypto/ ├── barcode/ ├── network/ ├── geo/ ├── helper/ ├── rand/ ├── data/ ├── diff/ ├── time/ ├── text/ └── unicode/ build/add-ideas-toolbox-0.18.1.zip build/add-ideas-toolbox-0.18.1.zip.sha256 ``` The assembler verifies SHA-256 before opening an artifact, validates every app manifest with `@add-ideas/toolbox-contract`, requires its id/version to equal the lock, and smoke-checks each declared entry, icon, and packaged manifest asset after extraction. It rejects insecure or credential-bearing redirects, HTTP, `latest` aliases, ZIP traversal, absolute paths, symlinks, special files, duplicate paths, oversized entries, and unsafe compression ratios. Canonical path checks protect source and output trees even through symlink aliases, and publication rolls all outputs back if a staged rename fails. Artifacts are unpacked only under `apps/`. The assembler never runs artifact content. The archive writer sorts file names and fixes ZIP timestamps and modes so the same assembled directory produces stable bytes. To package an already assembled directory separately: ```sh npm run package:static -- \ --input build/toolbox \ --output artifacts/add-ideas-toolbox-0.18.1.zip ``` This also emits a `.sha256` sidecar. ## Local assembled container and publication `Containerfile` serves only the assembled files with unprivileged nginx on port 8080. It adds restrictive browser headers, same-origin isolation, explicit `application/javascript` for `.mjs` engine modules and `application/wasm`, immutable caching only for Vite-hashed assets and narrowly matched semver-versioned FFmpeg core files, and revalidation for all other files. The opaque-origin SVG preview iframe loads its packaged controller with a URI-exact CORS and cross-origin resource-policy exception; all other files retain the same-origin policy and every normal security header. Camera access is denied by default. It is granted to the dedicated `auth.toolbox.add-ideas.de` origin and, on the shared Toolbox host, only to `/apps/barcode/`; both apps still request it only after an explicit user action. If `AUTH_TOOLS_HOST` is customized, update the exact host entry in `deploy/nginx.conf` and Auth Tools' pinned WebAuthn host at the same time. Every Toolbox app, including Random Tools, is constrained to same-origin connections. Random Tools implements its random generators locally with browser APIs and never calls a third-party randomness service. The packaged policy intentionally does not grant CSP `unsafe-eval`. SaxonJS's `ixsl:eval()` extension is therefore unsupported in this deployment profile; normal local XML/XSLT transformations do not require that permission. Assemble first, then: ```sh podman build -f Containerfile \ -t git.add-ideas.de/lotobo/toolbox:0.18.1 . podman run --rm -p 8080:8080 \ git.add-ideas.de/lotobo/toolbox:0.18.1 ``` For a direct-port local deployment after assembly, use the separate example: ```sh docker compose -f compose.example.yaml up -d --build ``` Publish both common architectures from a buildx-enabled workstation or Gitea runner: ```sh docker login git.add-ideas.de docker buildx build \ --platform linux/amd64,linux/arm64 \ --file Containerfile.release \ --tag git.add-ideas.de/lotobo/toolbox:0.18.1 \ --tag git.add-ideas.de/lotobo/toolbox:0.18 \ --push . ``` The default unprivileged nginx image is the security-fixed `1.31.3-alpine` baseline pinned to its reviewed multi-architecture digest. Re-resolve and review that digest whenever the base image is upgraded, then record it in the release notes. ## Manual Gitea publication checklist No credentials belong in this repository. The publishing workstation or runner needs permission to push code, releases, and container packages to `lotobo/toolbox-portal`. 1. Run `npm ci`, `npm test`, `npm run lint`, and `npm run build` from a clean checkout of the intended portal tag. 2. Publish each app's versioned ZIP, `.sha256`, `toolbox-app.json`, changelog, and licence notices in its own Gitea release. 3. Verify downloaded app assets with `sha256sum -c .sha256`; copy those exact values into a reviewed toolbox lock. 4. Run the assembler and serve `build/toolbox` from a nested test path. Open all 26 apps, switch between them, and confirm the encoded `toolbox` context. 5. Verify the distribution with `(cd build && sha256sum -c add-ideas-toolbox-0.18.1.zip.sha256)`. 6. Commit the reviewed lock, tag the toolbox release (for example `v0.18.1`), and push the branch and tag to Gitea. 7. In Gitea, open **Releases → New release**, select the tag, and upload the static ZIP plus its `.sha256` file. Do not use a mutable “latest” URL in a future lock. 8. Build and push the AMD64/ARM64 OCI image as shown above. Record the resulting multi-architecture manifest digest in the release notes. For Gitea Actions, store registry credentials as repository secrets, check out the exact tag, install with `npm ci`, run the same verification/assembly commands, and upload only the already-created ZIP/checksum and OCI image. The workflow must not re-resolve app versions or substitute a newer release. ## Existing tools | Tool | State and boundary | Principal workflows | Important concrete scope | Critical considerations and integrations | | ------------------- | ------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **`pdf-tools`** | Existing;
