Package: datasette-core
DatasetteAn instant JSON API for your SQLite databasesDatasette provides an instant, read-only JSON API for any SQLite database. It also provides tools  for packaging the database up as a Docker container and deploying that container to hosting providers such asZeit Now.Got CSV data? Usecsvs-to-sqliteto convert them to SQLite, then publish them with Datasette. Or tryDatasette Publish, a web app that lets you upload CSV data and deploy it using Datasette without needing to install any software.Documentation:http://datasette.readthedocs.io/Examples:https://github.com/simonw/datasette/wiki/DatasettesNews23rd May 2018:Datasette 0.22.1 bugfixplus we now useversioneer20th May 2018:Datasette 0.22: Datasette Facets5th May 2018:Datasette 0.21: New _shape=, new _size=, search within columns25th April 2018:Exploring the UK Register of Members Interests with SQL and Datasette- a tutorial describing howregister-of-members-interests.datasettes.comwas built (source code here)20th April 2018:Datasette plugins, and building a clustered map visualization- introducing Datasette's new plugin system anddatasette-cluster-map, a plugin for visualizing data on a map20th April 2018:Datasette 0.20: static assets and templates for plugins16th April 2018:Datasette 0.19: plugins preview14th April 2018:Datasette 0.18: units9th April 2018:Datasette 0.15: sort by column28th March 2018:Baltimore Sun Public Salary Records- a data journalism project from the Baltimore Sun powered by Datasette - source codeis available here27th March 2018:Cloud-first: Rapid webapp deployment using containers- a tutorial covering deploying Datasette using Microsoft Azure by the Research Software Engineering team at Imperial College London28th January 2018:Analyzing my Twitter followers with Datasette- a tutorial on using Datasette to analyze follower data pulled from the Twitter API17th January 2018:Datasette Publish: a web app for publishing CSV files as an online database12th December 2017:Building a location to time zone API with SpatiaLite, OpenStreetMap and Datasette9th December 2017:Datasette 0.14: customization edition25th November 2017:New in Datasette: filters, foreign keys and search13th November 2017:Datasette: instantly create and publish an API for your SQLite databasesInstallationpip3 install datasetteDatasette requires Python 3.5 or higher.Basic usagedatasette serve path/to/database.dbThis will start a web server on port 8001 - visithttp://localhost:8001/to access the web interface.serveis the default subcommand, you can omit it if you like.Use Chrome on OS X?
