streamingrat/ratproxy

A simple reverse proxy for testing AWS lambda functions locally.

ratproxy

Ratproxy is a simple reverse proxy server to let you simulate something like AWS cloudfront sitting in front of your services.

Installation:

go install github.com/streamingrat/ratproxy@latest

By default ratproxy will use the environment variable RATPROXY_FILENAME to open the config file. If not set uses ratproxy.yaml.

Configuration: You configure the ratproxy with a yaml file like the following, which configures two services listening on two different ports.

ratproxy.yaml

listen: 0.0.0.0:1414
targets:
 - name: server1
   type: lambda
   target: http://localhost:10000
   path: /service1/
 - name: server2
   target: http://localhost:1313
   path: /

ratproxy's Issues

Add admin listener

Add ability to create an admin listener at a port

This will let you look at the request logs, see the config, and change the config and re-write the ratproxy.yaml file.

Add `exec` param to `target` to run a process

In the target section, add exec with a line to run something and capture the logs. The working directory should be relative to the ratproxy.yaml file, with a name exec-working-dir The logs can be seen in the admin listener.

Expected configuration:

listen: 0.0.0.0:1414
targets:
  - name: npm-run-vue-app
    target: http://localhost:5173
    path: /vue/
    exec: npm run dev
    exec-working-dir: ./web/vue-app
  - name: other-target
