Wires the backend's 402 entitlement responses to Ethan's usage-limit modals (#6623) instead of the old upgrade toast. On a limit hit the apiClient interceptor now pops the matching modal and shows no toast: - subscribed team over its spending cap -> openSpendCapModal() - un-subscribed team over its free grant -> openFreeLimitModal() paygErrorInterceptor: - classifyPaygError also recognises 402 PAYG_LIMIT_REACHED (the API-key path), alongside the existing FEATURE_DEGRADED (JWT/web path); both pick the modal. - handlePaygError fires the modal via the subscribed flag (extractSubscribed), defaulting to the free-limit modal when absent. No toast. SIGNUP_REQUIRED (anonymous) keeps its existing signup-modal event. EntitlementGuard: FEATURE_DEGRADED 402 body now carries `subscribed` (it already did on PAYG_LIMIT_REACHED), so the web path can choose free-limit vs spend-cap. Tests: interceptor opens the right modal per sentinel × subscribed (and defaults to free when subscribed is absent); guard asserts `subscribed` on the body. :saas:test, spotless, eslint, saas tsc, and the interceptor vitest all green. Covers direct UI/API tool calls (the apiClient catch point). The async policy-run path (402 happens server-side; FE polls run status) is a separate follow-up.
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 ESLint + cycle detectiontask 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/, ESLint, Prettier — 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.
