Redirector

Lazy NodeJS Redirect

Don't bother if you can properly set up NGINX.

The premise here is to redirect traffic from URL A to URL B.

Declare domains

Environment Variables

• Set the MAP_PREFIX env variable. All your entries should be prefixed.

• Add multiple variables where:

  1. The key is the: {prefix}{domain_to_redirect_from}

  2. The value is a stringified JSON: {domain: domain_to_redirect_to, keepPath: boolean}

  3. The keepPath property preserves the original path after the mapping

  4. For example

     prefix = RD_
     {prefix}{domain_to_redirect_from} = '{"domain":"{domain_to_redirect_to}","keepPath":true}'

JSON

• Set the REDIRECT_JSON_PATH env variable to the JSON file path
• The path is read like so: process.cwd() + `/` + process.env.REDIRECT_JSON_PATH
• Check here

How to

Standalone server

• Configure these env variables

|Variable|Purpose| |--------|-------| |LAZY_REDIRECTOR_SERVER|Set to true to boot the server| |PORT|The server port. Defaults to 8000| |DEFAULT_ROUTE|A domain to redirect traffic if no mapping is found| |ERROR_ROUTE|A domain to redirect traffic if an error occured| |TOKEN|Optionally set it up. Include it as a URL param to crash the application| |MAP_PREFIX|The prefix that all domain-related env variables should start with| |FORCE_SSL|Set to true to force SSL to all incoming traffic| |REDIRECT_JSON_PATH|Set the filepath to read the JSON file|

Run in DEV

Set the enc variable ENVIRONMENT to "SERVER_DEV", and node server/index.js

Module

• Require the module

• Use the {name}.map function to parse the domain list from

  1. env variables
  2. JSON file

• Add the {name}.redirector middleware to the express chain
