webpack, with no configuration

The smallest webpack project there is: two source files, no config file, and the defaults. It exists to show what webpack does before you tell it anything, which is to read src/index.js and write dist/main.js.

Part of the webpack lesson.

Run it

npm install
NODE_OPTIONS=--openssl-legacy-provider npx webpack

One flag you will need

webpack 4 hashes modules with md4, and OpenSSL 3 removed md4 from its default provider, so on Node 17 and later a build stops before it starts:

Error: error:0308010C:digital envelope routines::unsupported
code: 'ERR_OSSL_EVP_UNSUPPORTED'

That is not a problem with this example, and upgrading webpack is not the answer for notes pinned to their era. Ask node for the old provider:

NODE_OPTIONS=--openssl-legacy-provider npm run build

Measured on Node 24: crypto.createHash('md4') throws without that flag and succeeds with it, and the build then completes normally.
