# Folio (web)
|
|
|
|
A React + Vite port of the folio personal-ledger app: login with demo
|
|
credentials, create accounts, add credits and debits. Exists as the
|
|
minimal web example sanderling runs its property-based specs against.
|
|
|
|
## Stack
|
|
|
|
- React 19 + Vite + TypeScript
|
|
- Stable HTML `id` attributes on every interactive element so the spec
|
|
targets DOM nodes by id, not by aria-label parsing
|
|
- `data-*` attributes (`data-cents`, `data-account-id`, `data-txn-count`)
|
|
carry structured numeric state for property assertions
|
|
|
|
## Prerequisites
|
|
|
|
- `just`
|
|
- [`bun`](https://bun.sh) (installs the JS toolchain; the project uses
|
|
`bun.lock`, not `package-lock.json` or `pnpm-lock.yaml`)
|
|
- Chrome installed (sanderling drives it via CDP)
|
|
|
|
```sh
|
|
bun install
|
|
```
|
|
|
|
## Demo credentials
|
|
|
|
```
|
|
email: [email protected]
|
|
password: ledger123
|
|
```
|
|
|
|
## Run a sanderling test
|
|
|
|
```sh
|
|
just test
|
|
```
|
|
|
|
The justfile boots the Vite dev server on port 5173, waits for the port
|
|
to respond, then runs `sanderling test --platform web --bundle-id
|
|
http://localhost:5173` against it. Override the port with `PORT=4000 just
|
|
test`; `DURATION`, `SEED`, and `OUTPUT` work the same way as in the KMP
|
|
folio example.
|
|
|
|
Traces land in `./sanderling/runs/<timestamp>/`.
|
|
|
|
## How it connects to sanderling
|
|
|
|
- The spec at `sanderling/spec.ts` finds elements by HTML `id`
|
|
(`#email`, `#add-account`, `#ledger`, `#txn-amount`, ...). Anything
|
|
the spec touches has a stable id in the markup.
|
|
- Numeric state the spec asserts on is exposed via `data-cents` and
|
|
similar attributes. The spec reads `el.attrs["data-cents"]` rather
|
|
than parsing currency strings out of `aria-label`.
|
|
- Account cards expose `data-account-id` + `data-balance` so the
|
|
spec can correlate cards across steps without depending on DOM order.
|
|
- `just test` invokes `sanderling test --platform web`, which connects
|
|
to Chrome via the Chrome DevTools Protocol; no extension or app SDK
|
|
is involved.
