[bug\_fix] error:0308010C:digital envelope routines::unsupported

Set NODE\_OPTIONS=--openssl-legacy-provider \(temporary\), or upgrade to webpack 5 or vite which support OpenSSL 3.0. Root cause: Node.js 17\+ uses OpenSSL 3.0 which changes crypto hash algorithms; legacy webpack 4 calls crypto.createHash in a way incompatible with OpenSSL 3 strict mode.

Journey Context:
You upgrade your local Node.js from 16 to 18 to get new features, then try to start your Create React App project. Instead of starting, it crashes with 'error:0308010C:digital envelope routines::unsupported' and a stack trace mentioning crypto.js. You search the error and find GitHub issues on the Node.js repository explaining that Node 17 switched to OpenSSL 3.0 which has stricter algorithms. You discover that webpack 4 \(used by older react-scripts\) uses crypto.createHash in a legacy way that OpenSSL 3 rejects. The rabbit hole leads to two solutions: either downgrade Node \(not ideal\), enable the legacy OpenSSL provider via NODE\_OPTIONS=--openssl-legacy-provider \(quick fix\), or upgrade to webpack 5 / latest react-scripts which properly support OpenSSL 3. You apply the environment variable as a temporary band-aid while planning the webpack upgrade.
