Pittsburgh Lenten Fish Fry Map

The Pittsburgh Lenten Fish Fry Map is the brainchild of Hollen Barmer, who has tirelessly dedicated her time since 2012 inventorying the rich array of Lenten Fish Fry events that occur every spring in Western Pennsylvania. Friends of Fish Fries help with website development, hosting, and data maintenance!

Where Does the Fish Fry data shown on the map come from?

The raw data isn't here! That is by design. The map gets data from the Fish Fry API @ fishfry.codeforpgh.com/api/fishfries. Anyone can use that URL to get data to make their own fish fry map, or do things with the Fish Fry data that we haven't thought of. If you want to learn more about the database and API, head over to the Fish Fry Form repository.

Occassional snapshots of the data are kept in public/data for local fallback and posterity.

Developer Quickstart

Prerequisites

• Node.js 22.x (matches CI)
• npm 10+

1) Install dependencies

npm ci

2) Configure environment

Create a local env file:

cp .env.example .env

Current variables:

• VITE_FISHFRY_API_URL=https://data.pghfishfry.org/api/fishfries/
• VITE_FISHFRY_FALLBACK_URL=/data/fishfrymap.geojson
• VITE_MAPBOX_TOKEN= (optional, enables Mapbox geocoding suggestions)
• VITE_CLIENT_ERROR_DSN= (optional, client-side error reporting target)
• VITE_CLIENT_ERROR_SAMPLE_RATE=1 (0..1)

3) Start local development server

npm run dev

App runs at http://localhost:5173.

4) Run tests

Unit tests:

npm run test:unit

Playwright parity tests (first-time setup):

npx playwright install --with-deps chromium
npm run test:parity

Run all tests:

npm test

5) Build and preview production bundle

npm run build
npm run preview

npm run build outputs to dist/.

Scripts

• npm run dev starts Vite dev server
• npm run build builds production bundle
• npm run preview serves the production bundle
• npm run test:unit runs Vitest unit tests
• npm run test:parity runs Playwright parity tests
• npm test runs both suites

Project Layout

• src/ app source code
• src/features/ UI and map features
• src/store/ Redux Toolkit slices and APIs
• src/domain/ shared business logic (filters, date logic, normalization)
• src/styles/ app styles and theme overrides
• public/data/fishfrymap.geojson fallback dataset used when API is unavailable

Theming

• Base theme: bootswatch/dist/darkly/bootstrap.min.css (imported in src/main.jsx)
• Brand overrides: src/styles/theme-overrides.css
• App-level custom styles: src/styles/app.css

Primary brand color is set to #fcb82e in src/styles/theme-overrides.css.

Data Source

Map data is fetched from:

• https://data.pghfishfry.org/api/fishfries/

If the primary API is unavailable, the app falls back to:

• /data/fishfrymap.geojson

If you want to learn more about the API and curation tooling, see:

• CodeForPittsburgh/fishfryform

Deployment

npm run deploy will run the build script and deploy the compiled site to GitHub pages.
