postcss-import-part

PostCSS plugin to import external file content at any place (like partial import).

To import adjacent file, path should be relative (like ./_part.css). Can import from node_modules (or web_modules) as well.

Currently recursive imports are not allowed.

You can also specify Parsers for imported files by extension.

Syntax

@import-part <string>;

where
<string> is path to file or module name.

Example

div
{
	@import-part "./imports/imported.pcss";
}

Output:

div
	.imported
	{
		color: red;
	}
}

You can find more examples in tests.

Install

npm install --save-dev postcss-import-part

Usage

It’s asynchronous plugin, so use should youse promises or async/await.

Source file path is required to resolve relative paths. If this path is not specified, root option is used (process.cwd() by default).

In this example used custom resolver to process paths, started from ~/, as relative to __dirname.

const postcss = require( 'postcss' );
const importJson = require( 'postcss-import-json' ).default;

const css = '@import-part "~/fixtures/imports/imported.pcss";';
const options = {
	resolve: ( path ) => (
		/^~\//.test( path )
		? resolve( __dirname, path.substr( 2 ) )
		: path
	),
};

postcss( [globalVars( options )] )
	.process(
		css,
		{from: '/tmp/test.css'},
	)
	.then(
		( result ) =>
		{
			console.log( result.css ); // => '.imported\n{\n\tcolor: red;\n}'
		},
	);

}

resolve

Type: ( uri: string, basedir: string, options: PluginOptions ): string | Promise<string> Default: undefined
