json tagged file loader

This loader allows you to tag files with a json header on top, and it will split the json tag during the processing, before it is attached back later

Example:

webpack.config.js

{
	test: /\.html$/,
	use: [
		{
			loader: 'json-tagged-file-loader',
			options: {
				destructure: true,
				defaultExportName: 'code',
				inputEsModule: false,
				outputEsModule: true,
				schema: {
					type: 'object',
					properties: {
						"date": {
							"type": "string",
							"format": "date"
						},
					},
					required: ["date"],
					additionalProperties: false,
				},
				extras: {
					title: 'detect-title-html',
				},
				loaders: [
					{
						loader: "html-loader",
						options: {
							minimize: true,
							esModule: false,
						},
					},
				],
			}
		},
	],
},

folder/test.html

{
    "date": "2020-03-15",
}
<h1>My blog post</h1>
<p>More content</p>

Will produce the following module:

// Module
var code = "<h1>My blog post</h1> <p>More content</p> ";
// Exports
export default code;
export const date = "2020-03-15";
export const slug = 'folder/test'
export const title = 'My blog post'

TODO

• Add configuration ptions to the slug generator
• Use something better than a regex in the html title detector
• Expand the validation schema with validations for schema, loaders and extras
