cf workers: TypeError: Cannot read properties of undefined (reading 'eval')

[konsumer]

I am trying to use the Durable Object state as the store, on a CF worker:

import { Ratelimit } from '@upstash/ratelimit'
import { error } from 'itty-router'

import { getClient } from './graphql/index.js'

export default class StoreDurableObject {
  constructor (state, env) {
    this.state = state
    state.cache ||= new Map()
    this.ratelimit = new Ratelimit({
      limiter: Ratelimit.slidingWindow(10, '10 s'),
      ephemeralCache: state.cache
    })
  }

  async fetch (req, env) {
    const { success } = await this.ratelimit.blockUntilReady(req.headers.get('CF-Connecting-IP'), 10_000)
    if (!success) {
      return error(429, 'Rate-limit exceeded.')
    }

    const graphql = await getClient({ req, env, state: this.state })
    const { query, variables = {} } = await req.json()
    return new Response(JSON.stringify(await graphql(query, variables)))
  }
}

And I get this:

✘ [ERROR] Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'eval')

Is there a better way to do this?

Is this project dead?

@konsumer Nope, it's not. We'll take care of it as soon as possible.

Here is a working gist file for you that utilizes ratelimit, redis and durable object: https://gist.github.com/ogzhanolguncu/53b13094c9b123b2e29c9ac8b0078cd8

Also just to make sure I tested this with both local and deployed version both works fine.

@ogzhanolguncu I appreciate the example. I was trying to use the rate-limiter without redis (directly using DO storage for the cache.) I ended up moving to durable-limiter, which does what I want.
