dclient

A client CLI utility for Datasette instances

Installation

Install this tool using pip:

pip install dclient

If you want to install it in the same virtual environment as Datasette (to use it as a plugin) you can instead run:

datasette install dclient

Standalone v.s. plugin

Once installed you can use this tool like so:

dclient --help

If you also have Datasette installed in the same environment it will register itself as a command plugin.

This means you can run any of these commands using datasette client instead, like this:

datasette client --help
datasette client query https://latest.datasette.io/fixtures "select * from facetable limit 1"

Running queries

You can run SQL queries against a Datasette instance like this:

$ dclient query https://latest.datasette.io/fixtures "select * from facetable limit 1"

Output:
