Parquet table

A webapp that displays the contents of a remote Parquet file in a table format.

This app is adapted from the hyparquet demo, and relies on Hyparam's tools: hyparquet to read the Parquet files, hyperparam that provides web workers to run hyparquet in another thread, and hightable to fetch and show the rows in a virtual table.

Run the app locally

npm i
npm run dev

Then open http://localhost:5173 in your browser.

Usage

The webapp can be configured using the following URL parameters:

• url: URL of the Parquet file to load
• iframe: if present, the app will be rendered in an iframe-friendly mode
• lens: initial view mode, can be table, metadata, or layout (default: table)
