React native web issue with react native vector icons in storybook

问题

I created a project using react native web and I got react native icons working for web and mobile except on storybook. I'm not sure how to tell storybooks webpack config to load FontAwesome fonts. I tried adding FontAwesome in the preview-head.html but Still not showing the icons just a rectangle as a placeholder. What I would like is to have my icons showing up in the storybook webpack server.

.storybook/main.js:

const webpack = require('webpack');
const path = require('path');
const rootDir = path.join(__dirname, '..');
module.exports = {
  stories: ['../src/storybook/stories/*.stories.tsx'],
  // addons: ['@storybook/addon-docs', '@storybook/addon-viewport', '@storybook/addon-knobs/', '@storybook/addon-links/', '@storybook/addon-actions/'],
  webpackFinal: async config => {
      config.module.rules.push({
          test: /\.(ts|tsx)$/,
          use: [
              {
                    loader: require.resolve('awesome-typescript-loader'),
                    options: {
                        transpileOnly: true
                    }
              }
          ],
      },
      {
        test: /\.ttf$/,
        loader: 'url-loader', // or directly file-loader
        include: path.resolve(
          __dirname,
          '../node_modules/react-native-vector-icons',
        ),
      }, 
           {

        try {

            }
</script>

package.json

"storybook:web": "start-storybook -p 6006"

I think the problem exist in preview-head.html and I know I can't use import modules in the script tag but not sure where else to load fontAwesome so storybook can pick it up. Thanks!

回答1:

For anyone having problems with this I needed to be specific on which file to be included for the url loader.

This change fixed the error:

     {
        test: /\.ttf$/,
        loader: 'url-loader', // or directly file-loader
        include: path.resolve(
          __dirname,
          '../node_modules/react-native-vector-icons/FontAwesome5.js',
        ),
      },

I also moved the font awesome script into the preview.js file
