If you are using NodeJs 17 for development purposes and your framework is either Angular or VueJs or React and using Webpack, This can be caused by web pack nodejs 17: digital envelope routines::unsupported · Issue #14532 · webpack/webpack (github.com).

Node 17 has announced one workaround for this.

If you hit an ERR_OSSL_EVP_UNSUPPORTED error in your application with Node.js 17, it’s likely that your application or a module you’re using is attempting to use an algorithm or key size which is no longer allowed by default with OpenSSL 3.0. A new command-line option, --openssl-legacy-provider, has been added to revert to the legacy provider as a temporary workaround for these tightened restrictions.

To fix this issue you need to set NODE_OPTIONS environment vale to --openssl-legacy-provider there are several ways to set this environment variable.

On UNIX based system you can use export or on windows, you can use the set command.

$ export NODE_OPTIONS=--openssl-legacy-provider

> set NODE_OPTIONS=--openssl-legacy-provider

Or you can do this using package.json the file scripts section as given below

"scripts": {
    "start": "react-scripts --openssl-legacy-provider start",
    "build": "react-scripts --openssl-legacy-provider build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
