Configuring Paperclip With Your Project

For existing projects, you'll need to manually configure Paperclip. If you're starting fresh, just follow the steps in the installation doc.

First up, be sure to have run npx paperclip-cli init in your existing project directory. This will install necessary dependencies & also include a paperclip.config.json that's required.

Webpack Setup

Documentation for this can be found in the Webpack Integration page. The only thing you really need to configure is:

  • paperclip-loader - compiles PC files to JSX.
  • style-loader - required since Paperclip emits CSS.
  • css-loader - required with style-loader.
  • file-loader - required for CSS files that have url()'s in them & other media.

Create React App (CRA)

If you're using CRA, then just run yarn paperclip build --write in your project directory to emit JS files. After that, you can import any component like so:

import * as myComponentStyles from "./my-component.pc.js";
<myComponentStyles.MyComponent />

I'd recommend that you include this in your .gitignore too:


Also, to make it easier you can include the build script in your start script like so:

"name": "my-app-name",
"scripts": {
"start": "react-scripts start & paperclip build --watch --write"

☝ This will start the Paperclip compiler in parallel with your usual start script.

Here's a walkthrough:

If you're using TypeScript, you can generate Typed Definitions from Paperclip files by running:

yarn paperclip build --definition --write

This will write *.pc.d.ts files in in the same directory as their corresponding *.pc file. I'd also recommend that you include *.pc.d.ts in your .gitignore file.

☝ This command will generate definitions files based on the compiler you're using. So if you're using paperclip-compiler-react, then React Typed Definition files will be generated for you. Configuration for the compiler can be found in the paperclip.config.json.
