For people who will meet this problem with tatum io v1 + react ! Developers said that it's problem of react, they will fix it in V2
You can use tatum io V1 with node js !

I've added all dependencies that might fix this bug, but still have fs problem

App.js

import React from "react";

import {

  deployMarketplaceListing,

  sendMarketplaceApproveErc20Spending,

  sendMarketplaceBuyListing,

  sendMarketplaceCreateListing,

  sendCeloSmartContractReadMethodInvocationTransaction,

  sendAuctionApproveNftTransfer,

} from "@tatumio/tatum";



const App = () => {

  <>

    <div>

      <h1>TEST</h1>

    </div>

  </>;

};



export default App;

after this imports I had 40+ errors. I've fixed most of them with this file

config-overrides.js

const webpack = require("webpack");



module.exports = function override(config) {

  const fallback = config.resolve.fallback || {};

  Object.assign(fallback, {

    crypto: require.resolve("crypto-browserify"),

    stream: require.resolve("stream-browserify"),

    assert: require.resolve("assert"),

    http: require.resolve("stream-http"),

    https: require.resolve("https-browserify"),

    os: require.resolve("os-browserify"),

    url: require.resolve("url"),

    path: require.resolve("path-browserify"),

  });

  config.resolve.fallback = fallback;

  config.plugins = (config.plugins || []).concat([

    new webpack.ProvidePlugin({

      process: "process/browser",

      Buffer: ["buffer", "Buffer"],

    }),

  ]);

  return config;

};

Than I have this one err multiple 8 times

ERROR in ./node_modules/@elrondnetwork/bls-wasm/bls_c.js 54:30-43

Than I've tried to fix them with

webpack.config.js

module.exports = (phase, { defaultConfig }) => {

  return {

    ...defaultConfig,



    webpack: (config) => {

      config.resolve = {

        ...config.resolve,

        fallback: {

          fs: false,

          path: false,

          os: false,

        },

        node: {

          fs: "empty",

        },

      };

      return config;

    },

  };

};

It didn't help a lot, than I've add to package.json these lines

"browser": {

    "fs": false,

    "path": false,

    "os": false

  },

So I've stacked at it, and trying to find solution for 2 hours, has anybody some ideas, how to fix that ? Thank you.
