Evidence JavaScript Source Plugin

This is a JavaScript source for Evidence. It allows you to run arbitrary JavaScript code as a data source. It's a quick way to get data into Evidence without having to create a new connector.

1. Launch the development server with npm run dev and navigate to the settings menu (localhost:3000/settings) to add a data source using this plugin.

2. Create a new source in the sources directory with a .js file like pokedex.js. The JS file should export a data object.

   let url = 'https://pokeapi.co/api/v2/pokemon/';
   
   const response = await fetch(url);
   const json = await response.json();
   const data = json.results;
   
   export { data };

3. You can then reference your data in markdown queries.

   ```sql pokedex
   select * from pokedex
   ```

Credentials

You can pass credentials via environment variables to your JS file. They must be prefixed with EVIDENCE_.

let key = process.env.EVIDENCE_API_KEY;
let url = 'https://whatever.com/api';

const response = await fetch(url, {
	headers: {
		'x-api-key': key
	}
});

const json = await response.json();
const data = json.results;

export { data };
