-
- ## Configuration
-
- A keyword list of rate limiters where a key is a limiter name and value is the limiter configuration. The basic configuration is a tuple where:
-
- * The first element: `scale` (Integer). The time scale in milliseconds.
- * The second element: `limit` (Integer). How many requests to limit in the time scale provided.
-
- It is also possible to have different limits for unauthenticated and authenticated users: the keyword value must be a list of two tuples where the first one is a config for unauthenticated users and the second one is for authenticated.
-
- To disable a limiter set its value to `nil`.
-
- ### Example
-
- config :pleroma, :rate_limit,
- one: {1000, 10},
- two: [{10_000, 10}, {10_000, 50}],
- foobar: nil
-
- Here we have three limiters:
-
- * `one` which is not over 10req/1s
- * `two` which has two limits: 10req/10s for unauthenticated users and 50req/10s for authenticated users
- * `foobar` which is disabled
-
- ## Usage
-
- AllowedSyntax:
-
- plug(Pleroma.Plugs.RateLimiter, :limiter_name)
- plug(Pleroma.Plugs.RateLimiter, {:limiter_name, options})
-
- Allowed options:
-
- * `bucket_name` overrides bucket name (e.g. to have a separate limit for a set of actions)
- * `params` appends values of specified request params (e.g. ["id"]) to bucket name
-
- Inside a controller:
-
- plug(Pleroma.Plugs.RateLimiter, :one when action == :one)
- plug(Pleroma.Plugs.RateLimiter, :two when action in [:two, :three])
-
- plug(
- Pleroma.Plugs.RateLimiter,
- {:status_id_action, bucket_name: "status_id_action:fav_unfav", params: ["id"]}
- when action in ~w(fav_status unfav_status)a
- )
-
- or inside a router pipeline:
-
- pipeline :api do
- ...
- plug(Pleroma.Plugs.RateLimiter, :one)
