Using Ant Design with NextJS (custom variables for Ant Design)

#react #nextjs #antdesign #100daysofcode

Day1: Started a new project to learn NextJS. Faced my first hurdle today when trying to setup a NextJS project with Ant Design. Using Ant Design with NextJS was fairly straight forward but when i tried to use custom variables for Ant Design, that's where things got tricky.

You can create a new NextJS project with

yarn create next-app app-name

npx create-next-app app-name

In the NextJS project, install Ant Design with

yarn add antd

npm install --save antd

create a new file called antd.less in the styles folder in the root of the project. Create a styles folder if you aren't already using one. antd.less is the file where all your custom variables will go

antd.less

@import "~antd/dist/antd.less";

@primary-color: #000; // primary color for all components
@link-color: #1890ff; // link color
@success-color: #52c41a; // success state color
@warning-color: #faad14; // warning state color
@error-color: #f5222d; // error state color
@font-size-base: 14px; // major text font size
@heading-color: rgba(0, 0, 0, 0.85); // heading text color
@text-color: rgba(0, 0, 0, 0.65); // major text color
@text-color-secondary: rgba(0, 0, 0, 0.45); // secondary text color
@disabled-color: rgba(0, 0, 0, 0.25); // disable state color
@border-radius-base: 4px; // major border radius
@border-color-base: #d9d9d9; // major border color
@box-shadow-base: 0 2px 8px rgba(0, 0, 0, 0.15); // major shadow for layers

You can customise these variables as you wish. Take a look at the Ant Design customisation docs for more.

In the pages directory create a new file called _app.js with the following contents

_app.js

import React from "react";
import App from "next/app";

import "../styles/antd.less";

class MyApp extends App {
  render() {
    const { Component, pageProps } = this.props;

    return <Component {...pageProps} />;
  }
}

export default MyApp;

You can also import any other global styles here

Right now, your custom variables will have no effect. For that to work you will need to install these packages -

yarn add @zeit/next-css @zeit/next-less @zeit/next-sass babel-plugin-import less

npm install --save @zeit/next-css @zeit/next-less @zeit/next-sass babel-plugin-import less

Now you will need to create a custom NextJS config for your variables to work

next.config.js

const withSass = require("@zeit/next-sass");
const withLess = require("@zeit/next-less");
const withCSS = require("@zeit/next-css");

const isProd = process.env.NODE_ENV === "production";

// fix: prevents error when .less files are required by node
if (typeof require !== "undefined") {
  require.extensions[".less"] = (file) => {};
}

module.exports = withCSS({
  cssModules: true,
  cssLoaderOptions: {
    importLoaders: 1,
    localIdentName: "[local]___[hash:base64:5]",
  },
  ...withLess(
    withSass({
      lessLoaderOptions: {
        javascriptEnabled: true,
      },
    })
  ),
});

With this config you will be able to use less, sass and css modules in your project. Your custom variables for Ant Design will now work

Thanks for the guide! Just as an FYI for anyone following this as well, and running into issues with importing the ~antd/dist/antd.less file within antd.less, make sure you install the less package targeted at version ^3.12.2.

It looks like version ^4.0.0 is installed by default and triggers the following error:

error - ./styles/antd.less

.@{ant-prefix}-anchor {
  .reset-component;
                ^
Unrecognized input. Possibly missing '(' in mixin call.

May I translate this article into Japanese and post it on my blog?
Actually, in Japan, there are few articles about Ant Design.

Burhanuddin Udaipurwala • Jul 21 '20

Sure. Go ahead!

dmamira • Jul 23 '20

Thank you!

You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See webpack.js.org/concepts#loaders

@import "~antd/dist/antd.less";

Burhanuddin Udaipurwala • Aug 30 '20

Hey, make sure you copied next.config.js file correctly. Less files require a special loader to be used. Also recheck that you performed all steps

Teejay85 • May 8 '21

I am having this problem too but I copied and pasted your next.config.js file. Is there a specific folder this file should go under?

Joel Grenon • Feb 1 '21 • Edited

Nice detailed solution. thanks. Did you have the chance to use it with next@10? Seems that there's an issue with webpack and mini-css-extract-plugin when using latest version of next. I just reverted back to version 9 and it's working like a charm :)

isaack okello brian • Aug 30 '20

Yarn start not working, sorry Newbie here. Also can you show me how to install and use storybook in this project?

Burhanuddin Udaipurwala • Aug 30 '20

Have you installed yarn on your computer? You can also npm if you haven't.

isaack okello brian • Aug 30 '20

It worked thank you so much. Btw is it an idea that you can create a boilerplate on git hub for antd and storybook? Think more like an enterprise boilerplate for UX designers who still learning the ropes to code. BTW thanks a mil for this
