yarn add --dev react-app-rewired crypto-browserify stream-browserify assert stream-http https-browserify os-browserify url buffer process
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"),
});
config.resolve.fallback = fallback;
config.plugins = (config.plugins || []).concat([
new webpack.ProvidePlugin({
process: "process/browser",
Buffer: ["buffer", "Buffer"],
}),
]);
return config;
};
