nexiliary
Heroes of the Storm auxiliary web app.
From the moment you spawn into a match it tells you what is coming and when, spoken aloud
and shown on a phone or second screen: objective spawns, camp timings, minion waves, talent
tier windows, and short prompts about what to prepare.
The game has no live data available to a web app, so nexiliary works from the match clock
plus a small number of anchor taps, and is explicit about how confident it is in any given
number. It never asserts something it cannot derive.
Status
The live app works, on all fifteen battlegrounds, as a single-player local app. Shared
sessions over a relay are the one thing left and need a Cloudflare account.
No battleground is marked verified, so nothing renders as exact except minion waves.
That is deliberate: timings are hand-authored from published guides, and the app is not
allowed to claim precision until a map has been timed by hand in a few custom games.
Running it
corepack enable
pnpm install
pnpm dev # http://localhost:5173
pnpm --filter @nexiliary/web dev:lan # also on the LAN, for a phone
pnpm test
pnpm typecheck
Use the deployed address on the phone, not a LAN one. Screen Wake Lock requires a secure
context, so on a plain http://192.168.x.x address the API is not restricted, it is
absent — the screen sleeps mid-match and takes the speech with it, and there is no
fallback that works. dev:lan is for looking at layout on a phone, not for playing.
Settings reports what is actually holding the screen, and says so plainly when nothing is.
Deploying
pnpm --filter @nexiliary/web deploy
A Cloudflare Worker serving static assets. Real certificate, so Wake Lock works and the
service worker registers, which is what makes it installable — an installed PWA is also
markedly harder for a phone to discard mid-match.
Pick a battleground, tap start match as you spawn in, then tap objective ended
during the regroup after each objective fight. That tap is the whole interaction. Without
it the app is accurate for a few objective cycles and then honestly goes quiet about
objectives, while waves, camps, talent tiers and the death timer carry on unaffected.
Layout
packages/engine the whole product: projection, confidence, cues. Zero dependencies
packages/maps fifteen battlegrounds and the cue text, as data with a schema
apps/web Vite + React SPA. No timing logic
