NativeBase next-adapter integration with Icons

Copy
const { withNativebase } = require('@native-base/next-adapter');

module.exports = withNativebase({
  dependencies: [
    '@expo/next-adapter',
    'react-native-vector-icons',
    'react-native-vector-icons-for-web',
  ],
  nextConfig: {
    projectRoot: __dirname,
    webpack: (config, options) => {
      config.resolve.alias = {
        ...(config.resolve.alias || {}),
        'react-native$': 'react-native-web',
        '@expo/vector-icons': 'react-native-vector-icons',
      };
      config.resolve.extensions = [
        '.web.js',
        '.web.ts',
        '.web.tsx',
        ...config.resolve.extensions,
      ];
      return config;
    },
  },
});

Re-export the custom Document component in the pages/_document.js file of your Next.js project.

This will ensure react-native-web styling works.

Wraps all the css in style tag on server side (thus preventing css flicker issue)

Or you can create the file using following command

Copy
mkdir pages; touch pages/_document.js

Update your pages/_document.js with the below content.

Copy
import { default as NativebaseDocument } from "@native-base/next-adapter/document";
import NextDocument, { Html, Head, Main, NextScript } from "next/document";
export { default as ExpoDocument } from "@expo/next-adapter/document";

Create a babel.config.js and use

babel-preset-expo

yarn

npx

Update your babel.config.js with the below content.

Copy
module.exports = {
  presets: ['@expo/next-adapter/babel'],
};

Example

Copy
import React from 'react';
import { Box, Icon } from 'native-base';
import Entypo from '@expo/vector-icons/Entypo';

export default function App() {
  return (
    <Box>
      <Icon
        as={Entypo}
        name="user"
        color="coolGray.800"
        _dark={{
          color: 'warmGray.50',
        }}
      />
    </Box>
  );
}
