Coverage was hardcoded to Gen 9. Now it reads the selected game: only that generation's types get rows (no Fairy pre-Gen 6, no Steel/Dark pre-Gen 2), member typings are era-accurate via the snapshot's pastTypes, and the type chart / STAB maths run at the game's generation. Compare's Type row follows suit. The panel re-renders on a game switch. New "Weak spots" block above the grid: types that hit 2+ members super-effectively, or that a member is weak to and nobody resists (those get a "0 resist" flag), each listing the exposed members. Plus a "no resist to" line for types the whole team only takes neutrally but can't wall. The grid itself swaps the plain "weak" count for a diverging resist/weak bar and tints rows where 2+ members are weak.

# Pokédex PWA
|
|
|
|
A responsive, offline-capable Pokédex reference built on
|
|
[PokéAPI](https://pokeapi.co/). Vanilla JS + Vite + Workbox — no UI
|
|
framework.
|
|
|
|
## Two headline features
|
|
|
|
| Feature | How it works |
|
|
| --- | --- |
|
|
| **Game series selection** | Pick a *game* (PokéAPI version group, e.g. Scarlet & Violet). If it has more than one regional dex (Paldea / Kitakami / Blueberry) a sub-dex switcher appears. The choice drives which species show, their regional numbering, and which version's flavor text the detail page uses. Stored in `localStorage`. |
|
|
| **Unified Pokémon selection** | One tracking record per Pokémon, keyed by **National Dex id**. Mark Pikachu once and every game's view reflects it — each dex computes its own "Seen / Caught" totals by intersecting its species list with that single map. The active Pokémon is also a single deep-linkable route (`#/pokemon/25`). |
|
|
|
|
## Data & storage split
|
|
|
|
- **Preferences + tracking state** → `localStorage` (`pdx.settings`, `pdx.selection`). Tiny, synchronous, restored on reload.
|
|
- **Build-time snapshot** (`src/data/snapshot.json`, ~150 KB) → generated by `npm run snapshot` from PokéAPI: every species (id, name, generation, types), all regional Pokédex lists, and all version groups. Precached by the service worker, so the list / search / game switching work on the first offline launch.
|
|
- **Detail data** (stats, abilities, flavor text, evolution) → fetched lazily from `pokeapi.co` per Pokémon, then cached by the service worker (stale-while-revalidate, 30-day TTL).
|
|
- **Sprites** → cache-first with a capped LRU.
|
|
|
|
Export / import of `settings` + `selection` as JSON lives in **Settings**.
|
|
|
|
## Scripts
|
|
|
|
```bash
|
|
npm install
|
|
npm run snapshot # fetch data from PokéAPI -> src/data/snapshot.json (run once; refreshes if >30 days old)
|
|
npm run dev # vite dev server
|
|
npm run build # runs snapshot (prebuild) then vite build
|
|
npm run preview # serve the production build (needed to exercise the service worker)
|
|
```
|
|
|
|
Deploying under a sub-path (e.g. GitHub Pages project site): `BASE_PATH=/repo-name/ npm run build`.
|
|
|
|
## Docker
|
|
|
|
Multi-stage build (Node → nginx) that serves the static `dist/`:
|
|
|
|
```bash
|
|
docker compose up --build # → http://localhost:8080
|
|
# or without compose:
|
|
docker build -t pokedex-pwa .
|
|
docker run --rm -p 8080:80 pokedex-pwa
|
|
```
|
|
|
|
The build stage runs `npm run build`, whose `prebuild` step fetches the
|
|
PokéAPI snapshot — so `docker build` needs network access to `pokeapi.co`
|
|
unless a fresh `src/data/snapshot.json` is already present (it gets copied in
|
|
and reused). Serving under a sub-path: `docker build --build-arg BASE_PATH=/dex/ .`.
|
|
`nginx.conf` sets the SPA fallback and long-cache headers for `/assets/*`
|
|
while keeping `index.html` / `sw.js` uncached.
|
|
|
|
## Project layout
|
|
|
|

|
|
router.js hash router (#/, #/pokemon/:id, #/games, #/search, #/settings)
|
|
sw.js Workbox service worker (injectManifest)
|
|

|
|
data/ snapshot loader, pokedex resolver, lazy API client
|
|

|
## Status
|
|
|
|
Working app with a type-themed UI:
|
|
|
|
- **Dex grid** — type-tinted cards (official artwork, spotlight, ghost number),
|
|
per-dex progress, name/number filter, caught/favorite filters.
|
|
- **Forms** — Megas, Gigantamax, regional forms and alternate formes in the
|
|
snapshot; a pill switcher on the detail page rebuilds types / stats /
|
|
matchups / abilities / learnset / artwork for the chosen form. Purely
|
|
cosmetic variants (Unown's 27 letters, Vivillon's 19 patterns, Furfrou
|
|
trims, seasonal Deerling/Sawsbuck, Flabébé line colours, Alcremie's 62
|
|
decorations, Pikachu caps — 278 across 50 species) get a separate compact
|
|
"Appearance" dropdown that only swaps the sprite. Cards show a "+N forms"
|
|
badge.
|
|
- **Detail** — type-gradient hero + tabbed sheet (About / Stats / Evolution /
|
|
Moves / Locations); coloured animated stat bars; defensive type matchups;
|
|
evolution chain re-parented to the selected game's generation; learnset with
|
|
per-move power/type/accuracy/PP/effect (era-accurate via `past_values`,
|
|
incl. pre-Gen-4 physical/special-by-type); wild encounter locations.
|
|
- **Game-aware** — abilities gated to Gen 3+ (hidden to Gen 5+); type chart
|
|
applies Gen 1 / pre-Gen 6 rules.
|
|
- **Games** — overlay picker with stylised version-colour cover tiles,
|
|
sub-dex switch, and an "All games" (National, no gen limits) option.
|
|
- **Search** — tabbed lookup: Pokémon, Moves and Items, all browsable
|
|
offline from the snapshot. Moves filter by type / damage class / "TMs in
|
|
this game" and sort by power / accuracy / recency; Items filter by
|
|
category. Each has its own detail page. Query, scroll, tab and filters
|
|
persist.
|
|
- **Team** — a lineup of up to 6. Coverage leads with a "weak spots"
|
|
summary (types that hit 2+ members, or that someone's weak to and nobody
|
|
resists), then a full matchup grid with a diverging resist◀│▶weak bar per
|
|
type; plus offensive STAB gaps and at-a-glance stats. A Compare table
|
|
stacks the six side by side. All matchup maths follow the selected game —
|
|
its generation's type chart and era-accurate typings (pre-Gen-6 Clefairy
|
|
is Normal, etc.). Toggleable in the nav from Settings.
|
|
- **Settings** — theme (System / Light / Dark / Black / Sepia) + accent
|
|
colour, sprite style, JSON export/import.
|
|
- **PWA** — Workbox SW: precache shell + snapshot, SWR for API JSON,
|
|
cache-first LRU for sprites, in-app update toast.
|
|
|
|
Not yet done: version-exclusive badges, type/generation filters on the grid,
|
|
an interactive region map (PokéAPI has no map imagery or coordinates),
|
|
skeleton loaders, install-prompt handling, PNG/maskable raster icons
|
|
(currently SVG only), and a Lighthouse PWA pass.
|
|
|
|
## Notes
|
|
|
|
- `npm audit` reports the known esbuild dev-server advisory via Vite 5. It
|
|
affects the local dev server only, not the production build. Vite 8 (which
|
|
fixes it) requires a newer Node than this environment has.
