## What Switching editor -> processor (or reloading) unmounts every editor provider, which emptied the workbench. This PR mirrors the workbench into per-tab sessionStorage and refills an empty one from that record on the next mount: - **Files, selection, view and active document survive** the shell switch and reloads. Each recorded file is resolved to its *current leaf* version on restore, so a file versioned by a policy or another tab comes back at its latest state. - **The switch back lands where the user left**: the processor sidebar's "editor" button consumes a one-shot return path saved at switch time. - **The app switch respects unsaved changes**: `useOtherAppSwitch` (proprietary + saas) now routes through `requestNavigation`, so the same warning guards it as any other navigation. - Desktop shadows `WorkbenchSessionPersistence` with a stub (OS-launched files own boot there). ## How to test I've run through each of these manually: - Upload several PDFs in the editor, select a couple, and switch to the Active Files grid. Click "Open PDF Processor" in the sidebar footer, then switch back to the editor. The same files, selection and view should return, and you should land on the editor page you left. - Open a document in the viewer, then reload the tab. The workbench should refill and come back on the viewer with the same document active. - With unsaved changes in a tool, click the processor switch. The unsaved-changes warning should appear, and the switch should only proceed if you confirm. - Open a second browser tab with different files. Each tab should restore its own workbench independently (the record is per-tab sessionStorage). - While in the processor, delete one of the open files from storage, then switch back. The remaining files should restore and a warning toast should report "Restored X of Y files". --------- Co-authored-by: Claude <noreply@anthropic.com>
Frontend
All frontend commands are run from the repository root using Task:
task frontend:dev— start Vite dev server (localhost:5173)task frontend:build— production buildtask frontend:test— run teststask frontend:test:watch— run tests in watch modetask frontend:lint— run lintingtask frontend:typecheck— run TypeScript type checkingtask frontend:check— run typecheck + lint + testtask frontend:install— install npm dependencies
For desktop app development, see the Tauri section below.
Layout
frontend/ is a workspace containing one or more apps. Today it holds the
PDF editor under frontend/editor/; new apps (the developer portal, etc.)
will sit alongside it as siblings. Shared tooling — package.json, node_modules,
.storybook/, oxlint, oxfmt — lives at frontend/ so every app installs
once and lints with the same config.
Environment Variables
The editor's environment variables live in committed .env files at
frontend/editor/:
.env— used by all builds (core, proprietary, and as the base for desktop/SaaS).env.desktop— additional vars loaded in desktop (Tauri) mode.env.saas— additional vars loaded in SaaS mode
These files contain non-secret defaults and are checked into Git, so most dev work needs no further setup.
To override values locally (API keys, machine-specific settings), create an uncommitted sibling editor/.env.local / editor/.env.desktop.local / editor/.env.saas.local. Vite automatically layers these on top of the committed files.
Docker Setup
For Docker deployments and configuration, see the Docker README.
Tauri
All desktop tasks are available via Task. From the root of the repo:
Dev
task desktop:dev
This ensures the JLink runtime and backend JAR exist (skipping if already built), then starts Tauri in dev mode.
Build
task desktop:build
This does a full clean rebuild of the backend JAR and JLink runtime, then builds the Tauri app for production.
Platform-specific dev builds are also available:
task desktop:build:dev # No bundling
task desktop:build:dev:mac # macOS .app bundle
task desktop:build:dev:windows # Windows NSIS installer
task desktop:build:dev:linux # Linux AppImage
JLink Tasks
You can also run JLink steps individually:
task desktop:jlink # Build JAR + create JLink runtime
task desktop:jlink:jar # Build backend JAR only
task desktop:jlink:runtime # Create JLink custom JRE only
task desktop:jlink:clean # Remove JLink artifacts
Clean
task desktop:clean
Removes all desktop build artifacts including JLink runtime, bundled JARs, Cargo build, and dist/build directories.
