@imcp-pro/dsh-client-background

English | 中文

A dsh Web client bundle that replaces the base background with a randomly rotating Unsplash wallpaper, revealed through translucent surfaces.

Features

• 100 curated wallpapers rotate on a configurable interval.
• Runtime switch — disable the effect without uninstalling the plugin.
• Client-side update check — polls GitHub for a newer commit and surfaces the exact update command.
• No framework coupling — the visual effect uses only browser globals (document, Image, setInterval).

Requirements

• A dsh web profile (dsh --profile web, a.k.a. dsh web) with the web-app bundle.
• A dsh build that exposes the base theme tokens --dsw-alias-bg-base / --dsw-specific-sidebar-fill, toggles the body[data-ds-dark-theme] dark-mode attribute, and serves the Plugins settings panel.

Installation

From GitHub

dsh plugin --profile web add github:imcp-pro/dsh-client-background

The plugin's prepare script builds lib/ at install time (it is not committed), and pnpm ≥ 10 blocks a git dependency's build scripts until allowlisted. The first run may therefore fail with ERR_PNPM_GIT_DEP_PREPARE_NOT_ALLOWED — that is expected. To resolve it:

1. Copy the exact allowlist key printed under "For example" in the error: @imcp-pro/dsh-client-background@https://codeload.github.com/…/tar.gz/<commit>.
2. Paste it under allowBuilds in the web profile's pnpm-workspace.yaml (~/.dsh/profiles/web/pnpm-workspace.yaml), then re-run the command.

# ~/.dsh/profiles/web/pnpm-workspace.yaml
allowBuilds:
  "@imcp-pro/dsh-client-background@https://codeload.github.com/imcp-pro/dsh-client-background/tar.gz/<commit>": true

Note: the key is commit-bound — every new commit changes <commit>, so always copy the key from the current error. Keep the codeload tarball form (https://codeload.github.com/…/tar.gz/<commit>) verbatim, not git+https:// or git+ssh://.

From an agent (dsh / Claude Code / OpenCode)

Paste the following prompt into your agent; it installs the plugin and resolves the allowlist step for you:

Install the dsh background plugin for the web profile:

    dsh plugin --profile web add github:imcp-pro/dsh-client-background

If the command fails with `ERR_PNPM_GIT_DEP_PREPARE_NOT_ALLOWED` (or a `dsh:`
hint mentioning `allowBuilds`), copy the exact
`@imcp-pro/dsh-client-background@https://codeload.github.com/.../tar.gz/<commit>`
key printed in the error, add it under `allowBuilds` in
`~/.dsh/profiles/web/pnpm-workspace.yaml`, and re-run the same command. Then
confirm the plugin is listed under `dependencies` in
`~/.dsh/profiles/web/package.json`, report whether the install succeeded, and
remind the user to restart `dsh web` to load the plugin (do not restart it
yourself).

From a local checkout

npm run build
dsh plugin --profile web add .

Then restart dsh web; the background appears and persists across restarts.

Configuration

Open Settings → Plugins → Plugin list, then expand Wallpaper background under Global plugins:

Field	Default	Description
Enable background	on	runtime off switch; the plugin stays installed
Rotation interval (seconds)	20	how often the image auto-switches
Check for updates	off	periodically poll GitHub for a newer commit
Check interval (seconds)	21600	time between two update checks

Edits stage locally and apply on Save; Discard drops them. When a newer commit is found, the entry shows the update command to run (then restart).

Development

npm install
npm run build   # esbuild bundles + tsc declarations → lib/
npm test        # vitest (jsdom)

tsconfig.json maps the @deepseek-ai/dsh-* type imports to a sibling deepseek-harness source checkout (its lib/types), because the published dsh packages currently predate the source API this plugin targets. Point the paths entries at your own checkout before building.

Publishing

npm publish    # `prepare` runs the build; ships lib/ + cordis.patch.yml

The package ships lib/ and cordis.patch.yml. It declares dsh.bundle.patch (so dsh plugin add registers the layer), dsh.client (so the client-modules host serves the browser half), and a client-background settings namespace the Host half registers.

Notes

• Instant swap, not crossfade — preloading removes the loading flash, but the image still changes in one step.
• background-attachment: fixed is ignored on iOS Safari — the image scrolls with the page there.
• The update check is client-side — the browser polls the GitHub default branch and compares its commit with the one stamped into the bundle at build time, so it never mutates a running install.
