export error while bundling @fluentui/react with webpack


I am getting webpack 5.25.0 compiled with 7 warnings in 6734 ms with version 7.167.0 and with v8.10.1 I was getting 1513 they were all same and something like this, instead of createElement there will be another react function like useEffect, with v8 it was taking 5 minutes to bundle in dev mode though with v7 took 10 sec.

export 'createElement' (imported as 'React') was not found in 'react'

Here is the webpack config

webpack.common.ts

import path from "path";

      axios: path.resolve(__dirname, "./node_modules/axios"),
    },
  },
  plugins: [
    new HtmlWebpackPlugin({

  },

with v7 at least it is working with warnings and v8 there were webpack export errors too.

What I have tried so far

  1. Removing the tsconfig, so it can use the default one.
  2. allow synthetic default imports
  3. removing react hot loader
  4. Checked on CodeSand box with the same versions, everything working there so probably there is something's wrong with config.
  5. Downgrading to React 16

Solution

  • Somehow, there were multiple version/instance of React were in place, I assumed there is only as hooks were working correctly, aliasing the react with './node_modules/react' solved the issue for me
