ExFPL

Elixir client for the unofficial Fantasy Premier League public REST API.

Installation

Add :ex_fpl to your dependencies in mix.exs:

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

Quick start

# Bootstrap snapshot — players, teams, gameweeks. Cached in ETS for 1 hour.
{:ok, snapshot} = ExFPL.Bootstrap.fetch()
%ExFPL.Snapshot{teams: teams, players: players, events: events} = snapshot

# All fixtures, or just one gameweek's
{:ok, fixtures} = ExFPL.Fixtures.list()
{:ok, gw1}      = ExFPL.Fixtures.list(event: 1)

# Live gameweek data
{:ok, %ExFPL.LiveSnapshot{}} = ExFPL.Live.fetch(1)

# Per-player history and upcoming
{:ok, %ExFPL.PlayerSummary{}} = ExFPL.Players.summary(player_id)

# Manager / entry data
{:ok, %ExFPL.Entry{}}        = ExFPL.Entries.get(team_id)
{:ok, %ExFPL.EntryHistory{}} = ExFPL.Entries.history(team_id)
{:ok, %ExFPL.Picks{}}        = ExFPL.Entries.picks(team_id, gameweek)

# Classic and H2H league standings
{:ok, %ExFPL.ClassicStandings{}} = ExFPL.Leagues.Classic.standings(314)
{:ok, %ExFPL.ClassicStandings{}} = ExFPL.Leagues.Classic.standings(314, page: 2)

{:ok, %ExFPL.H2HStandings{}}     = ExFPL.Leagues.H2H.standings(999)
{:ok, h2h_matches}             = ExFPL.Leagues.H2H.matches(999, event: 5)

Resource modules

Every fetch function accepts:

• raw: true — return the raw JSON-decoded map (string keys preserved) instead of the struct, useful when you need fields not modelled on the struct.
• Any other key is forwarded to Req (e.g. retry: false, receive_timeout: 30_000).

Caching

ExFPL.Bootstrap.fetch/1 caches its (~1 MB) response in an application-supervised ETS table for one hour. Pass cache: false to bypass the cache; call ExFPL.Cache.invalidate/0 to clear it.

ExFPL.Bootstrap.fetch()                # cache hit on second call
ExFPL.Bootstrap.fetch(cache: false)    # always fetches
ExFPL.Cache.invalidate()               # clear the cache

Authenticated endpoints

/me/ and /my-team/{team_id}/ require a session cookie obtained from a logged-in browser. This library does not implement the login flow itself — construct an ExFPL.Session from the cookie value:

session = ExFPL.Session.new(cookie: "pl_profile=...; sessionid=...")
{:ok, %ExFPL.Me{}}     = ExFPL.Entries.me(session: session)
{:ok, %ExFPL.MyTeam{}} = ExFPL.Entries.my_team(team_id, session: session)

Calling these without a session raises ArgumentError.

Telemetry

Each HTTP request emits a [:fpl, :http, :request] telemetry event with %{duration: native_time} and %{path: path, result: :ok | :error}.

:telemetry.attach("fpl-logger", [:fpl, :http, :request], &MyApp.handle/4, nil)

Testing

Tests stub the network with Req.Test. Configure your tests to use the stub plug:

# test/test_helper.exs
Application.put_env(:ex_fpl, :req_options, plug: {Req.Test, ExFPL.HTTPStub})
ExUnit.start()

Then in any test:

Req.Test.stub(ExFPL.HTTPStub, fn conn ->
  Req.Test.json(conn, %{"teams" => [...], "elements" => [...]})
end)

{:ok, %ExFPL.Snapshot{}} = ExFPL.Bootstrap.fetch(cache: false)
