Is there a way to clear MongoDB collection for a specific rate limiter programatically?

[yaroslav-perec]

Hi! First of all, thank you for the great library!

I have the next question "Is there a way to clear all data from a collection for a specific rate limiter"?

For example, I've created the next limiter:

const baseLimiter = new RateLimiterMongo({
    storeClient: connection,
    keyPrefix: 'rate_limiter_base',
    points: 100, // 100 attempts
    duration: 15 * 60, // within 15 minutes
});

Now I have this collection("rate_limiter_base") in my DB, and after some time I would like to clear all data from this collection using something like this:

baseLimiter.deleteAll();

But unfortunately, I couldn't find a similar API, so could you please help and tell me if there is a way to do this somehow?

Hi, thank you.
There is no built-in method to clean up a collection.
There is collection.deleteMany({}) in mongodb package for that. For the deleteMany method you'd need a collection name, which can be got from baseLimiter like baseLimiter.tableName.

The code to delete all documents from collections:

connection.collection(baseLimiter.tableName).deleteMany({})

Note, all expired documents removed from a collection automatically with expiring index built for every collection by expire.
