pathRewrite not matching regex pattern with variables

[alex996]

I am having an issue getting pathRewrite to match a regex pattern in context to variables in target.

Expected behavior

It should map a regex pattern with expressions (e.g. (.*)) to variables (e.g. $1).

Actual behavior

Proxy is not being created and the Express route yields 404.

Setup

• http-proxy-middleware: ^0.18.0
• server: express@^4.16.3

proxy middleware configuration

proxy('/user/(.*)/posts/(.*)', {
  pathRewrite: {
    '^/user/(.*)/posts/(.*)': '/api/user/$1/posts/$2'
  }
})

Is this functionality supported?

Capture groups are not supported.

You can provide a custom function to do the path rewriting the way you want:

@chimurai Thanks! Then never mind, I'll leave this as a feature request.

Will consider adding it if more users have to need for this.
