Tik Tok

Try using pug inside TypeScript.

Installation

yarn add webpack-preprocessor-pug-tsx -D

or

npm install webpack-preprocessor-pug-tsx -D

Configuration

module.exports = {
  // ...
  module: {
    rules: [
      {
        test: /\.(ts|tsx)$/,
        use: [
          'babel-loader',
          {
            loader: 'webpack-preprocessor-pug-tsx',
            options: {},
          },
        ],
      },
    ],
  },
};

Options

includes

type: string[]

default: ['jsx', 'React']

Variable that must be included among imported libs.

replace

type: {[key: string]: string}

default: {'jsx': '/** @jsx jsx */ jsx'}

When you need to transform the variable declared in includes.

// In webpack config...

{
  loader: 'webpack-preprocessor-pug-tsx',
  options: {
    replace: {
      jsx: '/** @jsx jsx */ jsx',
    },
  },
},

start

> type: string[]
>
> default: ['pug`', 'css`', ' `[^;,]', '\\(`']

Specifies the starting string of the element containing the backtick. Expressed as a regular expression string.

- pug` is the starting string of pug.
- css` is the starting string for emotion css.
-  `[^;] is the starting string for template strings.

Basic Process

Edit the document as follows:

import { jsx, css } from '@emotion/core';
import Button from './my/Button';
import ButtonGroup from './my/ButtonGroup';

...

return pug`
  div(css=[fullscreen, darkLayer])
  div(css=[fullscreen, whiteBoxWrapper])
    div(css=whiteBoxWrapper)
      h3 Confirm
      p 정말로 삭제하시 겠습니까?
      ButtonGroup
        Button cancel
        Button ok
`;

...

The following code...

/** @jsx jsx */ jsx;
Button;
ButtonGroup;
import { jsx, css } from '@emotion/core';
import Button from './my/Button';
import ButtonGroup from './my/ButtonGroup';

...

return pug`
  div(css=[fullscreen, darkLayer])
  div(css=[fullscreen, whiteBoxWrapper])
    div(css=whiteBoxWrapper)
      h3 Confirm
      p 정말로 삭제하시 겠습니까?
      ButtonGroup
        Button cancel
        Button ok
`;

...

React-native, Expo

• metro.config.js

const { getDefaultConfig } = require('metro-config');
const { setOptions } = require('webpack-preprocessor-pug-tsx');

setOptions({
  start: ['gql`'],
});

module.exports = (async () => {
  const {
    resolver: { sourceExts },
  } = await getDefaultConfig();
  return {
    transformer: {
      babelTransformerPath: require.resolve('webpack-preprocessor-pug-tsx'),
    },
    resolver: {
      sourceExts: [...sourceExts, 'tsx'],
    },
  };
})();

Caveats

The starting element of the backtick-wrapped phrase should be added to the start of options.

The following code may not work as expected:

const Button = styled.button`
  color: turquoise;
`;

render pug`
  Button This my button component.
`;

So, you need to add the following to the start of options.

{
  loader: 'webpack-preprocessor-pug-tsx',
  options: {
    start: ['button`'],
  },
},

There is no need to include /** @jsx jsx */ in the document.

The following code is added automatically.

before

import { jsx, css } from '@emotion/core';

after

/** @jsx jsx */ jsx;
import { jsx, css } from '@emotion/core';
