Static Data Export

This project relies on pre-generated JSON from the companion exporter:

https://github.com/junctor/info-export

Export workflow

1. Clone and install:

git clone https://github.com/junctor/info-export.git
cd info-export
npm install

2. Run export:

npm run export -- DEFCON33

3. Copy output into this project:

cp -r out/ht ../hackertracker-info/public

Data expectations

Each conference is served from:

/public/ht/<conference-slug>/

Typical structure:

entities/
indexes/
views/
derived/
manifest.json

This app depends on precomputed indexes such as:

• indexes/eventsByDay.json
• indexes/eventsByTag.json
• derived/tagIdsByLabel.json

Exports must match the expected schema used by the app.
