Extract shared datasette-modal web component for all modal dialogs
All eight modal dialogs (create table, alter table, insert/edit row,
delete row, set column type, column chooser, mobile column actions and
the navigation jump menu) previously each implemented their own <dialog>
creation, header/footer markup, backdrop-click and Escape handling,
busy-state guards, focus restoration and near-identical frame CSS.

This extracts all of that into a new <datasette-modal> web component
(datasette/static/datasette-modal.js) that wraps a native <dialog> and
provides:

- The standard modal frame, header (title + meta chip), footer and
  button styles, distributed via a stylesheet adopted into whichever
  document or shadow root the element is connected to - so it also
  works inside the shadow DOM of column-chooser and navigation-search
- Close on backdrop click and Escape, a busy property that blocks
  dismissal during saves, and a closeGuard hook for discard-changes
  confirmation prompts
- Focus restoration to the triggering element on close
- datasette-modal-open and datasette-modal-close events
- Per-dialog sizing via --datasette-modal-width /
  --datasette-modal-max-height custom properties

The component is exposed as window.DatasetteModal and via a new
datasetteManager.createModal() method, and is documented in
docs/javascript_plugins.rst as a stable public API for plugins.

This removes roughly 1,200 lines of duplicated frame markup, event
wiring and CSS across table.js, edit-tools.js, mobile-column-actions.js,
column-chooser.js, navigation-search.js and app.css, while keeping the
existing dialog ids, class names and inner structure intact.

Also adds Playwright coverage for the column chooser, mobile column
actions and set-column-type dialogs, which previously had none.

An open source multi-tool for exploring and publishing data

Datasette is a tool for exploring and publishing data. It helps people take data of any shape or size and publish that as an interactive, explorable website and accompanying API.

Datasette is aimed at data journalists, museum curators, archivists, local governments, scientists, researchers and anyone else who has data that they wish to share with the world.

Explore a demo, watch a video about the project or try it out on GitHub Codespaces.

Want to stay up-to-date with the project? Subscribe to the Datasette newsletter for tips, tricks and news on what's new in the Datasette ecosystem.

Installation

If you are on a Mac, Homebrew is the easiest way to install Datasette:

brew install datasette

You can also install it using pip or pipx:

pip install datasette

Datasette requires Python 3.8 or higher. We also have detailed installation instructions covering other options such as Docker.

Basic usage

datasette serve path/to/database.db

This will start a web server on port 8001 - visit http://localhost:8001/ to access the web interface.

serve is the default subcommand, you can omit it if you like.

Use Chrome on OS X? You can run datasette against your browser history like so:

 datasette ~/Library/Application\ Support/Google/Chrome/Default/History --nolock

Now visiting http://localhost:8001/History/downloads will show you a web interface to browse your downloads data:

metadata.json

If you want to include licensing and source information in the generated datasette website you can do so using a JSON file that looks something like this:

{
    "title": "Five Thirty Eight",
    "license": "CC Attribution 4.0 License",
    "license_url": "http://creativecommons.org/licenses/by/4.0/",
    "source": "fivethirtyeight/data on GitHub",
    "source_url": "https://github.com/fivethirtyeight/data"
}

Save this in metadata.json and run Datasette like so:

datasette serve fivethirtyeight.db -m metadata.json

The license and source information will be displayed on the index page and in the footer. They will also be included in the JSON produced by the API.

datasette publish

If you have Heroku or Google Cloud Run configured, Datasette can deploy one or more SQLite databases to the internet with a single command:

datasette publish heroku database.db

Or:

datasette publish cloudrun database.db

This will create a docker image containing both the datasette application and the specified SQLite database files. It will then deploy that image to Heroku or Cloud Run and give you a URL to access the resulting website and API.

See Publishing data in the documentation for more details.

Datasette Lite

Datasette Lite is Datasette packaged using WebAssembly so that it runs entirely in your browser, no Python web application server required. Read more about that in the Datasette Lite documentation.
