How to handle Bigint cursor? about node-redis

[leibale]

I'm guessing you are using v4.x? for this version the only way to solve it is to use .sendCommand directly:

await client.sendCommand(['SCAN', '0', 'MATCH', '*', 'COUNT', '1000']);

async function* scanIterator() {
  let cursor = '0';
  do {
    const reply = await this.sendCommand(['SCAN', cursor, 'MATCH', '*', 'COUNT', '1000']);
    cursor = reply[0];
    yield reply[1];
  } while (cursor !== '0');
}

for await (const chunk of scanIterator()) {
  // ...
}

this is already fixed in v5 which you can try using @redis/client@next.

Found a configuration 'string_numbers' in the v2.6.0 documentation. However, it does not seem to have that option in v4. the scan operation is still returning a number instead of a "string number". The cursor is still converted to 9286422431637965000
Tried with the small code

const redis = require('redis')
const client = redis.createClient({
    url: <my_redis_url>,
    string_numbers: true
}); 

const test = async () => {
     try { 
        await client.connect() 
        const reply = await client.scan("0", 'MATCH', '*' , 'COUNT', '1000')
        console.log(reply)
     } catch (err) {
        console.error(err)
     }
}
test()

await client.sendCommand(['SCAN', '0', 'MATCH', '*', 'COUNT', '1000']);

Yes, I am using v4.x.
It works when using sendCommand. I will try v5 next.
Thank you
