Installation

npm i mermaid-loader -D

Usage

Documentation: Using loaders

var html = require("mermaid!./diagram.mmd");
// => emits diagram.png as file in the output directory and returns the public url
// => returns i. e. "/public-path/diagram.png

By default the filename of the resulting file is the filename with .mmd extension replaced by .png extension

Filename templates

You can configure a custom filename template for your file using the query parameter name. For instance, to copy a file from your context directory into the output directory retaining the full directory structure, you might use ?name=[path][name].[ext].

mermaid-loader works like file-loader. More instructions here.

    module: {
        loaders: [
            { test: /\.mmd$/, loader: "mermaid" },
        ]

}
