- I needed a https reverse proxy with more complex filtering functionality and nginx and traefik weren't good enough
- to learn a new language I wanted to learn for a long time
- for funnies
- I needed to write tests for my redirecting logic and writing them in a real lang would have made it easier
there is a folder called middlewaresin which every file is executed as middleware, for now only the tool lang is supported buy in the future there will be support for different langs which will be run inside a sandbox env
in the handlers folder again you make a handwr for redirecting logic which should follow this function signature
fn handler(req: Req) -> string | null
where the return is the redirect url and if it is null we invoke the nest handleramd like that until one returns a string
also handles are executed in order e.g. First fails we ge the second etc....
- in the config object (either json file loaded from the config.json or as env) you can specify a file to which to save the logs for each request
- you can define your custom logging handler which must be called logging.scala and located in the root dir, if you dont want to make one you can sepcify the entry
loggingin yourconfig.jsonto eitherallornoneand to use a custom one it should be set tocustom. Also logging handlers are executed in seperate process so dont be afraid that it will hurt latency NOTE: when loading config it is first checked for he existence of an env and then for a file
Dont like json and managing configs, well just like any web server lib you can just pull the dependency in your scala project and start building on top of it. To see more

add this to your
build.sbtlibraryDependencies += "to do" % "to do " % "1.0.0"
Example
import com.to_do.ReverseProxy
class MyCustomReverseProxyImplementation extends ReverseProxy{
