Bundesschatz Archive

Historic return rates from bonds available at https://bundesschatz.at, shown as a chart and table in a Next.js app.

Features

• Interactive chart and data table for multiple bond terms.
• Date-range filtering and tabbed chart/table views.
• Data sourced automatically from https://bundesschatz.at every weekday via a scheduled GitHub Actions workflow.

Requirements

• Node.js 24 (see .nvmrc / .node-version).
• pnpm (see package.json packageManager entry).

Getting Started

Install dependencies:

pnpm install

Run the dev server:

pnpm dev

Build for production (static page output is in out directory):

pnpm build

Lint:

pnpm lint

Deployment

• Uses Next.js output export option.
• Static page is deployed to GitHub Pages.

Data

The app reads bundesschatz.csv at build time and transforms it into chart/table rows.

CSV columns:

"Product Key","Period Interval","Period Value","Date","Interest Rate","Green"

• Period Interval is M (months) or Y (years).
• Period Value + Period Interval map to the bond keys used in the UI (e.g. 1M, 4Y).

Update the CSV

There is a small fetcher script that appends new rows from the public Bundesschatz API:

node data-fetcher/index.cjs

It only adds rows that are not already present in bundesschatz.csv and sorts new rows by date before appending.
