typeorm-rate-limit-store

rate-limit-typeorm

A TypeORM store for express-rate-limit.
Designed for use with TypeORM as a backing store for express rate limiting in a clustered environment.

Installation

npm install typeorm-rate-limit-store

Usage

You will need to implement an entity for the rate-limiting model, and then instantiate the store by passing in that model.

Implement the IExpressRateLimitModel entity:

// ExpressRateLimitStoreModel.ts
import { Column, Entity, PrimaryColumn } from "typeorm";
import type {IExpressRateLimitModel} from 'typeorm-rate-limit-store';

@Entity()
export class ExpressRateLimitStoreModel implements IExpressRateLimitModel{
    @PrimaryColumn()
    public key: string;

    @Column()
    public totalHits: number;

    @Column()
    public resetTime: Date;
}

Instantiate the store passing in the model:

import {ExpressRateLimitTypeOrmStore} from 'typeorm-rate-limit-store';
import {ExpressRateLimitStoreModel} from "ExpressRateLimitStoreModel.js";

const repository = getDatastore().getRepository(ExpressRateLimitStoreModel)
app.use(
    rateLimit({
        windowMs: 1000,
        limit: 1,
        standardHeaders: true,
        store: new ExpressRateLimitTypeOrmStore(repository),
    }),
);

Options:

The ExpressRateLimitTypeOrmStore constructor takes the following parameters:

Option	Description	Required
repository	The type orm repository that is built from the IExpressRateLimitModel interface	True
prefix	A string that will prefix the key, use this if you require multiple instances of the ExpressRateLimitTypeOrmStore	False

Both CJS and ESM modules are provided, but it is assumed you will be using ESM as this package exports that as the default.
