How do I fix SSL certificate errors in webpack-dev-server?

I'm getting SSL certificate errors when I run my webpack-dev-server. How can I fix this?

SSL certificate errors usually occur when the server is using a self-signed certificate. You can resolve this by either trusting the certificate or generating a new one.

How do I generate a new SSL certificate for webpack-dev-server?

You can generate a new self-signed certificate using OpenSSL. Run the command: openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365 -nodes.

Once I have the certificate, how do I configure webpack-dev-server to use it?

You need to update your webpack configuration file. Add the following to your devServer settings: https: { key: fs.readFileSync('key.pem'), cert: fs.readFileSync('cert.pem') }.

Will this work for all browsers?

Most browsers will still show a warning for self-signed certificates. You can bypass this by adding an exception in your browser settings.
