How it works

This is a Reactive app: a plain text document that your browser turns into a working app — forms, live data, tables, statistics and even charts, with nothing to install or configure.

  1. Use it right away. Hit “Use this app”: it opens right in your browser, ready to go, with data saved only on your device.
  2. Your data stays yours. Everything is stored locally on your device, kept separate for each app: no account, no server, nothing to set up.
  3. Make it your own. The text below is the entire app: copy it, tweak fields, views and words, and your changes become interactive instantly.
  4. Share it as a file. An app is a simple file: save it, export it or share it with a link; and with encrypted collaboration several people edit the same data in real time.

## ECB exchange rates

Pick the base currency (ISO code: `EUR`, `USD`, `GBP`, `CHF`, `JPY`…): the
call re-runs by itself on every change.

::input[base]{value="EUR" placeholder="Base currency (e.g. EUR)"}

::api-query{url="https://api.frankfurter.dev/v1/latest?base={#base}" into="rates" pick="rates" as="pairs"}

**Click a bar** to single that currency out in the table (second click:
filter cleared).

::::dashboard{path="rates"}
::chart-bar{data="rates" x="key" y="value" height="18rem"}

:::table{path="rates" headers="Currency,Rate" pagesize="10"}
{key} | {value}
:::
::::

And a single rate as a reactive value, ready for a computation:

::api-query[eurUsd]{url="https://api.frankfurter.dev/v1/latest?base=EUR" pick="rates.USD"}

1 EUR = **:value[vt]{ref="#eurUsd"}** USD (ECB fixing, business days).
