Bandeira Elixir SDK

Official Elixir client SDK for Bandeira, a self-hosted feature flag service.

Install

Add to mix.exs:

def deps do
  [
    {:bandeira, "~> 0.1.0"}
  ]
end

Then run:

mix deps.get

Usage

alias Bandeira.{Client, Config, Context}

{:ok, client} =
  Client.start_link(%Config{
    url: "http://localhost:8080",
    token: "your-client-token"
  })

if Client.is_enabled(client, "my-flag", %Context{user_id: "user-123"}) do
  # feature is on
end

Client.close(client)

Notes

• The client polls /api/v1/flags in the background and caches flags in memory.
• is_enabled/3 is a pure in-memory lookup and does not do network I/O.
• Initial startup fails fast if the first fetch fails.
• Call close/1 when running unmanaged clients.
