# add·ideas Toolbox Portal
`toolbox-portal` is the static launcher and release assembler for the add·ideas
browser toolbox. Version `0.2.22` 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/`, `./apps/unicode/`, `./apps/flow/`, `./apps/subtitle/`,
`./apps/midi/`, `./apps/3d/`, `./apps/query/`, `./apps/scan/`,
`./apps/package/`, `./apps/label/`, `./apps/font/`, `./apps/fixture/`,
`./apps/minimize/`, `./apps/format-lab/`, `./apps/repro/`, `./apps/schema/`,
`./apps/log/`, `./apps/binary/`, `./apps/git/`, `./apps/api/`, `./apps/mail/`,
`./apps/calendar/`, `./apps/contact/`, `./apps/diagram/`, `./apps/token/`, and
`./apps/device/`).
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 0.19.0 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 v0.19.0 / Portal v0.2.22
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 0.3.1, Sudoku Tools 0.2.1, Colour Tools 0.1.0, Office Tools 0.1.0,
Random Tools 0.1.1, and the 0.1.0 releases of Image, File, EPUB, Archive,
Privacy, Crypto, Barcode, Network, Geo, Helper, Data, Diff, Time, Text, Unicode,
Flow, Subtitle, MIDI, 3D, Query, Scan, Package, Label, Font, Fixture, Minimize,
Format Lab, Repro, Log, Binary, Git, API, Mail, Calendar, Contact,
Diagram, Token, and Device Tools.
Schema Tools is pinned at its hardened v0.1.2 release.
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-0.19.0.zip
```
Existing output is refused. Pass `--force` only when replacing those exact
paths is intended. A successful run produces:

build/add-ideas-toolbox-0.19.0.zip
build/add-ideas-toolbox-0.19.0.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/<locked-target>`. 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-0.19.0.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, `application/wasm`, and
`application/gzip` for the bundled Scan OCR language model,
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/`, `/apps/scan/`, and
`/apps/device/`. Device Tools alone additionally receives microphone and screen-
capture policy at its exact path; every probe remains explicitly user initiated.
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:0.19.0 .
podman run --rm -p 8080:8080 \
git.add-ideas.de/lotobo/toolbox:0.19.0
```
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:0.19.0 \
--tag git.add-ideas.de/lotobo/toolbox:0.19 \
--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 <asset>.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 50 apps, switch between them, and confirm the encoded `toolbox`
context.
5. Verify the distribution with
`(cd build && sha256sum -c add-ideas-toolbox-0.19.0.zip.sha256)`.
6. Commit the reviewed lock, tag the toolbox release (for example `v0.19.0`), 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.

## Planned tools
No unreleased applications are currently listed here. New ideas should be added
only after their intended local-processing boundary and first honest release
scope are documented; shipped applications remain in the Existing tools table.
## Licensing
Portal source is `AGPL-3.0-only`; see `LICENSE`. The contract is Apache-2.0, and
each assembled application retains its own licence and notices. An assembled
ZIP/container is an aggregate of those independently licensed components; see
`THIRD_PARTY_NOTICES.md` and each `apps/<slug>/LICENSES/` directory.
