koa-simple-ratelimit

Rate limiter middleware for koa v2. Differs from koa-ratelimit by not depending on ratelimiter and using redis ttl (time to live) to handle expiration time remaining. This creates only one entry in redis instead of the three that node-ratelimiter does.

Installation

1npm install koa-simple-ratelimit

Example

1import Koa from 'koa';
2import redis from 'redis';
3
4import { ratelimit } from 'koa-simple-ratelimit';
5
6const app = new Koa();
7
8// Apply rate limit
9
10app.use(ratelimit({
11	db: redis.createClient(),
12	duration: 60000,
13	max: 100
14}));
15
16// Response middleware
17
18app.use((ctx, next) => {
19	ctx.body = 'Stuff!';
20	return next();
21});
22
23app.listen(4000);
24console.log('listening on port http://localhost:4000');

Options

db redis connection instance
max max requests within duration [2500]
duration of limit in milliseconds [3600000]
id id to compare requests [ip]
allowlist array of ids to allowlist
blocklist array of ids to blocklist
prefix redis key prefix ["limit"]
