run-dev

#!/bin/bash

# This script is a convenient way to run metacpan-web from a local system
# without using Docker or any VM solution.  It should be faster and more
# convenient to debug than running plackup manually.
#
# It starts two web servers.  The first on port 5001 using a simple server
# with no concurrency (to aid in debugging) to handle the dynamic requests.
# The second on port 8000 using a "fast" server that can handle many
# concurrent requests which will serve the static files and proxy to the
# first server.

# Rather than running plackup, you can simply run:
#
# ./run-dev
#
# or
#
# carton exec ./run-dev
#
# Then browse to http://localhost:8000/
