Encountering the dreaded `error:0308010c:digital envelope routines::unsupported` error? Don't panic! This cryptic message usually pops up when running Node.js applications, often after an upgrade. It stems from changes in OpenSSL's default algorithms and how they interact with older libraries.
The most common fix is surprisingly simple: tell Node.js to use the legacy OpenSSL provider. There are a couple of ways to achieve this:
**Option 1: Command Line Flag**
Before running your Node.js command, try prepending this:
`NODE_OPTIONS=--openssl-legacy-provider`
For example: `NODE_OPTIONS=--openssl-legacy-provider npm start`
**Option 2: Package.json Script**
Modify your `package.json`'s `scripts` section. Add the `NODE_OPTIONS` flag to the relevant start/run command:
`"start": "NODE_OPTIONS=--openssl-legacy-provider node app.js"`
These methods essentially tell Node.js to use older, compatible encryption methods. While a temporary workaround, consider updating your project's dependencies to use newer cryptography libraries for a more sustainable solution in the long run. Happy coding!
