Template String Transformation Babel plugin

This plugin allows you to process Template Strings with any transformers defined in .babelrc file based on string prefix. Please note that transformers will be applied in the same order they listed in configuration.

Example

.babelrc configuration:

{
    "plugins": [
        "babel-plugin-template-string-processing"
    ],
    "extra": {
        "babel-plugin-template-string-processing": [
            {
                "type": "postcss",
                "options": [
                    "postcss-nested",
                    ["autoprefixer", { browsers: ['last 10 versions'] }]
                ]
            }
        ]
    }
}

Template String in JavaScript file:

function style() {

    return `~postcss
        .block {
            display: flex;

            &__element {

            }
        }
    `;

}

Result:

function style() {
    return '.block { display: -webkit-box; display: -webkit-flex; display: -ms-flexbox; display: flex; } .block__element {}';
}

Please not how transformer prefix (type in plugin configuration) starts with ~ character.
