# Baz
[](https://github.com/atlas-xyz/baz/actions?query=workflow%3Atest)
[](https://hex.pm/packages/baz)
A chain native hybrid bazaar engine
[Getting Started](./docs/GETTING_STARTED.md) | [Commands](./docs/COMMANDS.md)
## What Can I Do? TLDR;
Stream NFT market data to create and manage orders with a near-uniform API across multiple venues
## Venues In Progress
| Venue | Collections | Events | Orders |
| ---------- | :---------: | :----: | :----: |
| OpenSea | [ ] | [ ] | [ ] |
| LooksRare | [ ] | [ ] | [ ] |
| X2Y2 | [ ] | [ ] | [ ] |
| Magic Eden | [ ] | [ ] | [ ] |
| Hyperspace | [ ] | [ ] | [ ] |
## Requirements
- TimescaleDB 2.5+
- Erlang 22+
- Elixir 1.13+
## Install
Add the `baz` package to your list of dependencies in `mix.exs`:
```elixir
def deps do
[
{:baz, "~> 0.0.17"}
]
end
```
Create an `.iex.exs` file in the root of your project and import the `baz` helper
```elixir
# .iex.exs
Application.put_env(:elixir, :ansi_enabled, true)
import Baz.IEx
```
Generate migrations
```bash
$ mix baz.gen.migration
```
Run migrations
```bash
$ mix ecto.migrate
```
## Upgrading Baz
Bump the required version number in `mix.exs` and download the dependencies.
```bash
$ mix deps.update baz
```
Regenerate new or updated migrations
```bash
$ mix baz.gen.migration
```
Rerun ecto migrations
```bash
$ mix ecto.migrate
```
## Logging Oban Jobs
To enable `oban` job logging configure `Oban.Telemetry` or your own logger within your supervision tree
```elixir
def start(_type, _args) do
children = [
MyApp.Repo,
MyApp.Endpoint,
{Oban, oban_opts()}
]
Oban.Telemetry.attach_default_logger(:info)
Supervisor.start_link(children, [strategy: :one_for_one, name: MyApp.Supervisor])
end
```
## Development
Ensure an instance of TimescaleDB is running
```bash
$ make start.db
```
Run an interactive Elixir shell to control `baz` via the [REPL commands](./docs/COMMANDS.md)
```bash
$ make start
```
## Test
```
$ make test
```
## Help Wanted :)
If you think this `baz` thing might be worthwhile and you don't see a feature
or venue listed we would love your contributions to add them! Feel free to
