Pako/zlib and yoga errors in Webpack 5

[harrismcc]

Describe the bug When I try to use react-pdf in my react app, I get the following error messages from Webpack (5.76.2). Using react 17.0.2, and babel/core 7.14.2. I'm including the polyfill for browserify-zlip in my webpack config, but it's still having these issues.

webpack 5.76.2 compiled with 5 errors in 33408 ms

To Reproduce In my webpack config, I have the following for resolve (note, there is other stuff in there for other libraries)

  resolve: {
    fallback: {
      stream: require.resolve('stream-browserify'),
      vm: require.resolve('vm-browserify'),
      punycode: require.resolve('punycode/'),
      util: require.resolve('util/'),
      os: require.resolve('os-browserify/browser'),
      crypto: require.resolve('crypto-browserify'),
      process: require.resolve('process/browser'),
      zlib: require.resolve('browserify-zlib'),
      stream: require.resolve('stream-browserify'),
      // util: require.resolve('util'),
      buffer: require.resolve('buffer'),
      assert: require.resolve('assert'),
    },
    // need to use require.resolve to ensure that only one instance of these are
    // loaded/bundled
    alias: {
      'styled-components': require.resolve(`styled-components`),
      'react-redux': require.resolve(`react-redux`),
    },
  },

Desktop (please complete the following information):

I was running into this issue and had to manually install pako.

Hello! Did you solve the problem after all? I'm facing the same thing :(

[chrishoward]

@harrismcc Did you manage to resolve this issue?

[alivtar]

Same problem here. Any updates for this?

This issue seems similar to https://github.com/diegomura/react-pdf/issues/2335. Even though Babel isn't mentioned, it might be useful to look at the solution there.

Installing pako fixed the issue for me initially, but I think using packageExtensions from #2335 is a better solution. It shows why pako is needed by fixing missing dependencies. Installing pako alone might be confusing for other developers since it isn’t used directly in the code.
