# Description of Changes Smaller scope than #6689 to try and get this finished. Replace ESLint and dpdm with Oxlint, a TS linter written in Rust so its performance is dramatically better than the existing tools we use. ## Speed improvement - Current ESLint run: 13.76s - Current dpdm run: 3.59s - Total time: 17.35s - New Oxlint run: 0.90s So Oxlint is about a 20x speed improvement. ## Differences When I last tried to do this, we could recreate our rules identically with Oxlint, but that's not true any more. Oxlint has no current equivalent for ESLint's `no-restricted-syntax` rule, which we were using to ban usages of `<button>` and stuff in specific components to try and encourage them to use our shared UI. This is a very recent addition to our linting config, and personally I'm willing to drop it for now at least. We can still ban specific imports in files, so the files which we were trying to enforce shared UI will still ban directly importing Mantine, so that'll probably be most of the cases still caught, but I think there are other ways we can encourage using the shared UI beyond just using the linter for it. I did try building a custom TS rule for it and it only slowed it down a tiny bit (it took 1.1s) but it had to be built on an unreleased alpha API which just sounds like a maintenance headache we don't need to deal with for a rule that we don't really need.
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, 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.
