# Living Dex Tracker
A web app to track completion of a living Pokédex.
## Developing
1. Clone the repository
2. Install the dependencies with `npm install`
3. Ensure that Docker is running
4. An example `.env` file is provided in the repository. You will need to copy `.env.example` to `.env` and fill in the values with your own credentials. For local development with Supabase running in Docker, you can use the following values:
- The `PUBLIC_SUPABASE_URL` will be `"http://127.0.0.1:54321"`
- The `PUBLIC_SUPABASE_ANON_KEY` will be the 'Publishable' authentication key displayed when you run Supabase in the terminal
- The `SUPABASE_SERVICE_ROLE_KEY` will be the 'Secret' authentication key displayed when you run Supabase in the terminal
5. Start local Supabase and a development server with `npm run dev:supabase`
6. The Pokédex data is automatically seeded via database migrations when Supabase starts
7. Create an account using the sign-up form and access the email it sends in [MailPit](http://127.0.0.1:54324/) to verify your email address.
N.B. All local emails are captured by MailPit when running Supabase in Docker.
8. You can now use [the app](http://localhost:5173/).
## Reference Data Updates
The seed data lives in `supabase/migrations/20260118001000_seed_reference_data.sql`. Update that migration directly when new data is added. You can access a local copy of [Supabase](http://localhost:54323/) to check it.
## Building
To create a production version:
```bash
npm run build
```
## Testing
The test suite is split by responsibility so a failure points to the correct layer:
- `tests/unit` contains fast, isolated tests for utilities, repositories, and services.
- `tests/data` validates the tracked Pokémon, game, region, dex, and sprite reference files.
- `tests/integration` checks the migrated Supabase schema, views, constraints, RLS, and repositories.
- `tests/bdd/features` is the executable Gherkin specification for user-visible behaviour. Step
definitions and browser fixtures live beside it under `tests/bdd`.
- `tests/build` verifies generated service-worker and manifest artifacts after each supported build.
Run the offline suites while developing. `test:fast` includes the coverage run, so there is no need
to run both:
```bash
npm run test:fast
```
Coverage is measured across all of `src/lib` (excluding type-only models and the browser-only
store/action modules) with global thresholds set to the current baseline, so new untested code lowers
the number instead of being invisible to the gate. Ratchet the thresholds in `vitest.config.mts` up as
coverage grows, never down.
Database and BDD tests require Docker and the local Supabase stack. The wrappers read the local keys
from `supabase status` at run time, so no keys are hard-coded in the test files; the local stack's
well-known demo keys do appear in `.env.local.example`, and no real credentials are committed:
```bash
npm run supabase:start
npm run supabase:reset
npm run test:integration
npm run test:bdd
```
`npm test` runs the complete CI-equivalent sequence and fails with setup instructions when Supabase is
not available. Individual layers are available as `test:unit`, `test:data`, `test:integration`,
`test:build`, and `test:bdd`.
Gherkin describes outcomes in domain language. Keep selectors, API calls, test-user provisioning, and
provider mocks in step definitions or support fixtures. `@product-review` marks a rule that should be
reviewed with product stakeholders, but does not skip it. Missing or ambiguous steps fail generation.
Google Drive and Dropbox scenarios use a local provider server (`scripts/mock-provider-server.mjs`)
and never contact real provider accounts. The endpoint overrides that point at it are refused unless
`ALLOW_PROVIDER_ENDPOINT_OVERRIDES=true`, the local test-stack/service-role variables are present,
and the override is a loopback URL. These endpoints receive the OAuth client secret and refresh
token, so they must not be redirectable in a deployed environment. `npm run test:bdd` supplies the
complete test context.
The mock's recorded requests, refresh counter and fail-uploads switch are reset before every scenario
by an auto fixture in `tests/bdd/fixtures.ts`. That reset is also why the suite runs with a single
worker: the mock is one shared process, so parallel scenarios would reset each other's state. A global
teardown deletes the users each run creates, so repeated local runs do not need a database reset.
Chromium is the only configured browser project. Playwright traces and screenshots are retained on
failure under `test-results`.
Password-reset scenarios follow recovery links generated by the local Supabase stack and verify both
the rejected old password and accepted replacement password. The application waits for Supabase to
confirm the recovery session before enabling the replacement form.
After sign-in, the application automatically stores a versioned, per-user read-only copy of every
Pokédex and its referenced artwork. Offline navigation opens a static viewer; all mutation and
authentication controls remain unavailable until connectivity returns. A successful sign-out removes
the user-specific snapshot and artwork caches from the device.
The current National Dex maximum is deliberately asserted as 1025. When adding a new generation,
update that expectation together with Pokémon data, the corresponding game/dex files, database seed,
and sprites. Data tests print the exact conflicting identities or broken references.
You can preview the production build with `npm run preview`.
## Sprites
The app uses WebP sprites from `static/sprites-small`. During builds we generate this folder from the
full-resolution PNGs in `static/sprites`:
```bash
npm run sprites:build
```
If you want to serve sprites locally, set `PUBLIC_USE_LOCAL_POKEMON_SPRITE_FOLDER="true"` in `.env`.
Otherwise the app defaults to GitHub raw for `static/sprites-small`.
## Hosting
The app is hosted on [Netlify](https://www.netlify.com/) at [pokedex.jcreek.co.uk](https://pokedex.jcreek.co.uk/).
The Pokédex data is stored in a [Supabase](https://supabase.com/) database.
User authentication is handled by [Supabase Auth](https://supabase.com/auth).
## Dependencies
The living dex tracker's sprite collection is derived from [PokéAPI Sprites](https://github.com/PokeAPI/sprites)
and converted to smaller WebP files in `static/sprites-small`. PokéAPI sprites are licensed under
[the Creative Commons CC0 1.0 Universal license](https://github.com/PokeAPI/sprites/blob/master/LICENCE.txt).
