# Why?

**This rate-limiter attempts to keep it e-z, with no additional functions.**

**All in all a basic package to rate-limit your clients.**

***Also used in the Fronvo [server](https://github.com/Fronvo/fronvo)***

# Installing

```

npm i @ezier/ratelimit

```

# Documentation

**Documentation for the Ezier Ratelimiter can be found at https://ezier-project.github.io/ratelimit/.**

# Examples

**Setup an instance of `EzierLimiter`:**

```ts

import { EzierLimiter } from '@ezier/ratelimit';

const ezierLimiter = new EzierLimiter({

    maxPoints: 10,

    clearDelay: 1000

});

```

**Consume points for a client:**

```ts

ezierLimiter.consumePoints('client-uid', 5);

```

**Handle a consumption error:**

```ts

import { EzierLimiterError } from '@ezier/ratelimit';

ezierLimiter.consumePoints('client-uid', 11)

.catch((err: EzierLimiterError) => {

    // EzierLimiterError check

    if(err.currentPoints) {

        console.log(`Client requested ${err.requestedPoints} points when it has ${err.currentPoints} points and maxPoints are ${err.maxPoints}.`);

    } else {

        console.log(`[${err.name}]: ${err.message}`);

    }

});

```

**Register middleware:**

```ts

ezierLimiter.$use({

    beforeConsumption: ({consumerKey, requestedPoints}) => {

        console.log(`Attempting to consume ${requestedPoints} points for ${consumerKey}...`)

    },

    afterConsumption: ({consumerKey, remainingPoints}) => {

        console.log(`[${consumerKey}]: ${remainingPoints} points remaining.`);

    }

});

```

**Stop the rate-limiter:**

```ts

ezierLimiter.stop()

.then(() => {

    console.log('The Ezier Ratelimiter has been stopped.');

});

```
