How to use koa-ratelimit - 3 common examples

import logger from './logs/log'
import userAgent from 'koa-useragent'
import error from 'koa-json-error'
import ratelimit from 'koa-ratelimit'
import redis from 'ioredis'

//Routes
import userActionsRouter from './routes/userActions'
import notesRouter from './routes/notes'

//Initialize app
const app = new Koa()

//Here's the rate limiter
app.use(
    ratelimit({
        db: new redis(),
        duration: 60000,
        errorMessage:
            "Hmm, you seem to be doing that a bit too much - wouldn't you say?",
        id: ctx => ctx.ip,
        headers: {
            remaining: 'Rate-Limit-Remaining',
            reset: 'Rate-Limit-Reset',
            total: 'Rate-Limit-Total',
        },
        max: 100,
    })
)

//Let's log each successful interaction. We'll also log each error - but not here,
//that's be done in the json error-handling middleware
