The nix package manager works on linux & mac, and ensures our app and its dependencies are exactly the same across machines (at the byte-level) by using a system of determinstic builds and input hashing. Using it is the fastest way to get all the needed packages on your machine. Install it with:
https://nixos.org/download.html
You might need to restart your shell or edit your PATH after the install (just follow the prompts).
Running nix-shell in this directory will fetch all the project's dependencies
and (while you're in the shell) add them to your PATH. This is not a
container, it's just a fancy shell environment. On first run it will take a
minute to download everything, so I find it eaiser to make it verbose:
nix-shell --verbose
If you have direnv, you can activate this shell every time you enter it in
the terminal. To enable this, install direnv
and run direnv allow in this directory.
In the nix-shell, the scripts/database script is already in your PATH, so run:
database startThis will install Elixir's dependencies and run migrations: packages using:
mix setup
Elixir will launch your app and put you in a REPL inside the app's context:
iex -S mix phx.server
Now you can visit localhost:4000 from your browser.
