const css = fs.readFileSync("./src/input.css", "utf8");

const processor = postcss([
    url({
        url    : folders,
        source : "./src",
        output : "./dist"
    })
]);

processor.process(css, {
    from : "./src/input.css",
    to   : "./dist/output.css"

Example

The source folder structure for static assets

├───src
    │   input.css
    │
    ├───components
    │   └───button
    │           background.png
    │           button.css
    │           icons.svg
    │
    └───site
            header.png
            site.css

will be maintained in the output location

├───dist
    │   output.css
    │
    ├───components
    │   └───button
    │           background.png
    │           icons.svg
    │
    └───site
            header.png

along with updating references to copied files as necessary.

Options

source

Root location to reference all assets from. Defaults to the from parameter provided by postcss but that often isn't very useful. In the Example above you would set it to "./src".

output

Directory to copy all assets to. Defaults to the directory of the to parameter provided by postcss. In the Example above it could have been set to "./dist" but would have chosen the directory correctly by default.
