dsh-updater

A full npm install of DeepSeek Harness rebuilds a 200-plus package monorepo in memory and can easily exceed a 1 GB heap limit inside Docker or other constrained environments. Re-resolving the entire dependency universe on every minor version bump is slow, wasteful, and brittle.

dsh-updater takes a narrower, safer path. It fetches only the changed @deepseek-ai/* tarballs from the npm registry, reuses node_modules and native addons already on disk, and skips third-party dependencies whose versions have not shifted. Before touching the running engine it writes a full backup to engine-bak, and if post-update verification fails it rolls back automatically. The whole flow avoids sudo, curl-pipe-bash, and live npm -g installs into a container volume. A Settings panel and a sidebar button make the update one click, and the restart strategy adapts to the environment: it exits cleanly so Compose can respawn the container, or it prompts you to quit and relaunch on a laptop without killing your session.

This plugin is ideal for anyone running DSH in Docker, nvm, pnpm or yarn global, Windows npm global, npx cache, or any other writable prefix — especially teams tracking the next dist-tag across private or scoped registries. It has zero runtime dependencies and only requires Node 20 or later.
