TeslaCacher

TeslaCacher is a Basic Cache Middleware for Tesla backed by Redix. It will cache GET requests for N milliseconds, if defined, otherwise for the lifetime of the Redis session. Requests other than GET are NOT cached.

Not to be confused with TeslaCache, which is backed by Cachex.

Installation

The package can be installed by adding tesla_cacher to your list of dependencies in mix.exs:

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

Usage:

TeslaCacher does not manage Redix for you, you must start and monitor it yourself and provide the details to the plugin:

defmodule MyClient do
  use Tesla

  plug Tesla.Middleware.Cacher,
    redix: :redix,
    expiry: :timer.seconds(2),
    timeout: :timer.seconds(5),
    prefix: :tesla_cacher
end

Options:

redix -- [required] the connection handle for redix. Can be an atom or a PID.

expiry -- [optional] (integer or :infinity) the expire time, in milliseconds. Default is :infinity.

timeout -- [optional] (integer or :infinity) request timeout, in milliseconds. Default is 5000.

prefix -- [optional] (atom or string) a prefix to be used for redis keys. | (pipe) is used as a separator to avoid lookup conflicts with common redis key schemes. Default is tesla_cacher.
