[bug\_fix] error:0308010C:digital envelope routines::unsupported \(OpenSSL 3.0\)

Set environment variable NODE\_OPTIONS=--openssl-legacy-provider before running the build command, or upgrade to webpack 5\+ and update all loaders/plugins to versions supporting OpenSSL 3.0, or downgrade to Node.js 16 LTS which uses OpenSSL 1.1.1.

Journey Context:
You upgrade your machine to Node.js 18 LTS \(or a teammate does\), and suddenly your React app \(created with Create React App 4 or using webpack 4\) fails to build with a cryptic OpenSSL error from crypto.js. You search the error and find it started with Node 17 which bundled OpenSSL 3.0, which has stricter providers. You try reinstalling node\_modules, clearing npm cache, even reinstalling Node. The issue persists because webpack 4's crypto usage triggers legacy OpenSSL routines. You find the workaround: setting NODE\_OPTIONS=--openssl-legacy-provider in your package.json scripts or environment. This tells Node to enable the legacy OpenSSL provider, allowing the old crypto calls to work. The permanent fix is upgrading to webpack 5 which properly handles OpenSSL 3.0.

environment: Node.js 17\+ \(especially 18/20\) with webpack 4, Create React App 4, or other old build tools using crypto · tags: openssl-3.0 webpack4 node-18 digital-envelope legacy-provider node_options · source: swarm · provenance: https://nodejs.org/api/cli.html\#--openssl-legacy-provider and https://github.com/nodejs/node/issues/40455
