Example PathMapper object

• Key of path mapper object takes the string type which can include the regex string. Key must start with leading /
• Value of path mapper object takes the string or object
  • If string then it must be a URL to the destination server.
  • If object then it should have two property URL (Destination Server URL) and rewriteURL (Either to append Destination URL with the incoming url or not);

const pathMapper = {
  '/8080/?(.*)': 'http://localhost:8080', // value must not end with trailing slash
  '/8081/?(.*)': {
    URL: 'http://localhost:8081',
    rewriteURL: false
    // since rewriteURL is false proxy will append '/8081/<regex url>' to http://localhost:8081 -> Final URL: 'http://localhost:8081/8081/<regex url>'
  },
  '/8081/static': {
    URL: 'http://localhost:8081',
    rewriteURL: true
    // since rewriteURL is true proxy will not append '/8081/static' to http://localhost:8081 -> Final URL: http://localhost:8081
  }
