## 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 | |||
