TODO.md: sub-project 2 marked done, with the three decisions sub-projects 3 and 4 should follow rather than re-decide — meter geometry lives in one pure module, two markups beat one reflowing grid with lying ARIA roles, and a table states its currency once rather than per cell. The year matrix faces the same responsive question with more columns to lose. Also recorded: cssTokens.test.ts matches source *text*, so it flags a token named in a comment as readily as one in a style attribute — which is exactly what it did to the comment explaining it. New in "still needs a human": nobody has confirmed the pre-destructive backup actually lands as an openable file. Both import and reset issue it and only proceed on success, but headless Chrome's download is not observable here. ARCHITECTURE.md: the two whole-dataset writes, replace() behind import and reset() behind Settings, take the same queue and the same write-before-snapshot rule as every mutation.

Budget 2.0
A personal budgeting PWA. Envelope-style monthly budgets with rollover, split purchases, finance plans, multi-currency, and JSON/ODS export. All data lives in your browser — there is no server and no account.
Development
bun install
bun --hot src/index.ts # dev server with hot reload
bun test # run the test suite
bun run build # production build into dist/
Self-hosting with Docker
docker build -t budget2 .
docker run --rm -p 3000:3000 budget2
To serve from a subpath, build and run with BUN_PUBLIC_BASE_PATH:
docker build -t budget2 --build-arg BUN_PUBLIC_BASE_PATH=/budget/ .
docker run --rm -p 3000:3000 -e BUN_PUBLIC_BASE_PATH=/budget/ budget2
GitHub Pages
Pushing to main builds and deploys to Pages automatically, using
/<repository-name>/ as the base path. Enable Pages with "GitHub Actions" as
the source in the repository settings.
Your data
Everything is stored in this browser's IndexedDB. Export regularly from Settings → Your data: the JSON export is both your backup and how you move your budget to another device. Import replaces everything and downloads a backup of your current data first.
Known limitations
- Data is per-browser. There is no account and no sync. If you clear this browser's site data, or move to a different browser or device, your budget is gone unless you exported it first. The JSON export is not just a nice-to-have backup — it is the only way to move a budget between devices.
- The install prompt is incomplete.
manifest.webmanifestcurrently only ships an SVG icon. Chrome requires PNG icons at 192×192 and 512×512 to offer the "Install app" prompt; until those are added, the app works fine as a regular tab but won't be installable on Chrome/Chromium.
