## Installation
Add `:aura` to your list of deps in `mix.exs`:
```elixir
{:aura, "~> 1.0"}
```
Then run `mix deps.get` to install Aura and its dependencies.
## Configuration
```elixir
config :aura,
# The hex-compliant backend for Aura to connect to
# This can also be passed in as an option to all service functions
# Default: https://hex.pm/api
# See "Testing" for other options
repo_url: System.get_env("AURA_REPO_URL", "http://localhost:4000/api"),
# API secret payload to use when making requests from the hex-compliant backend
# This cannot be passed in as an option to service functions.
# Please: Don't put the actual secret payload as plain text in your code.
# Default: nil
api_key: System.get_env("HEX_API_KEY")
```
## Smoke Test
```elixir
# Grab aura
{:ok, package} = Aura.Packages.get_package("aura")
latest_version = package.releases |> hd() |> Map.get(:version)
# Grab aura's latest release
{:ok, release} = Aura.Releases.get_release("aura", latest_version)
{:ok,
%Aura.Model.HexRelease{

## Implementation Overview
🚧 TODO
## Testing
> [!WARNING]
> All Aura tests expect to connect to a local hex instance
> and will **purposely crash** if it discovers it's testing against hex.pm.
You should be very mindful about issuing requests against a production hex API.
To make this easy, you can `docker compose up -d` from the root of this repository to launch a local instance
of [hexpm/hexpm](https://github.com/camatcode/hex_tiny?tab=readme-ov-file#hex_beefy) and set the `repo_url`
to http://localhost:4000/api in [Configuration](#configuration).
```bash
➜ docker compose up -d
[+] Running 1/1
✔ Container hex_beefy Started 0.1s
➜ curl http://localhost:4000/api | jq
{
"documentation_url": "http://docs.hexpm.apiary.io",
"key_url": "http://localhost:4000/api/keys/{name}",
"keys_url": "http://localhost:4000/api/keys",
"package_owners_url": "http://localhost:4000/api/packages/{name}/owners",
"package_release_url": "http://localhost:4000/api/packages/{name}/releases/{version}",
"package_url": "http://localhost:4000/api/packages/{name}",
"packages_url": "http://localhost:4000/api/packages"
}
```
## FAQ
> Why not use hex_core?
Fantastic question! I'd say for most cases, you should just use hex_core, or the associated Mix tasks to interact with
Hex. But here are a couple of motivations for using Aura.
1. hex_core can be intimidating to folks without a strong erlang background.
2. Aura is meant to be friendly to Elixir folks.
3. Aura's first aim is to be documented **to hell and back**.
4. The maintainer has larger plans that would use Aura as a base.
