To install Elixir/Erlang we do recommend using asdf.

After installing asdf, you can run those following commands to install Elixir/Erlang:

# enable elixir/erlang plugins on asdf
asdf plugin add elixir
asdf plugin add erlang

# clone the repo
git clone https://github.com/aschiavon91/harpoon.git && cd harpoon

# install version from '.tool-versions' file
asdf install

mv .example.env.local .env.local

mix setup

or using just

just start_dev

or using just

just start_prod

and the respective default value

PHX_HOST="0.0.0.0" # you may want to change this to your respective domain, if its running behind a reverse proxy
DATABASE_FILE="$HOME/.harpoon/harpoon_prod.sqlite"
SECRET_KEY_BASE="<autogenerated>"
PORT="4000"

Browser to http://localhost:4000/ and you should be redirected to http://localhost:4000/<session_id>.

Then, you can start making HTTP requests to http://<session_id>.localhost:4000/, and you should start seeing the requests in the dashboard.
