I finally fixed the issue, the problem is with version 3.62.0 from wrangler, I downgrade it to 3.61.

Hello! I am using

WorkerKV

WorkerKV

for some experiment and this is my code

await this.namespace.put(keyWithPrefix, JSON.stringify(payload), {
  expiration: Math.floor(payload.resetTime.getTime() / 1000),
});

await this.namespace.put(keyWithPrefix, JSON.stringify(payload), {
  expiration: Math.floor(payload.resetTime.getTime() / 1000),
});

await this.namespace.put(keyWithPrefix, JSON.stringify(payload), {
  expiration: Math.floor(payload.resetTime.getTime() / 1000),
});

await this.namespace.put(keyWithPrefix, JSON.stringify(payload), {
  expiration: Math.floor(payload.resetTime.getTime() / 1000),
});

So here are the problems I am facing -

The key is not getting deleted, I am still getting the old value when I fetch it
If I want to update the value for a key but still want to have the same expiration time, what will be implmentation for that? Should I just pass the
```
expiration
```
```
expiration
```
props again?

I

Ian•7/2/24, 3:37 AM

by the way, you'd be better served using a ternary instead of an if statement since a ternary always assigns something.

const payload = wasCreated
  ? {
      totalHits: payload.totalHits + 1,
      resetTime: new Date(payload.resetTime)
    }
  : {
       totalHits: 1,
       resetTime: new Date(Date.now() + this.windowMs),
    }

const payload = wasCreated
  ? {
      totalHits: payload.totalHits + 1,
      resetTime: new Date(payload.resetTime)
    }
  : {
       totalHits: 1,
       resetTime: new Date(Date.now() + this.windowMs),
    }

const payload = wasCreated
  ? {
      totalHits: payload.totalHits + 1,
      resetTime: new Date(payload.resetTime)
    }
  : {
       totalHits: 1,
       resetTime: new Date(Date.now() + this.windowMs),
    }

const payload = wasCreated
  ? {
      totalHits: payload.totalHits + 1,
      resetTime: new Date(payload.resetTime)
    }
  : {
       totalHits: 1,
       resetTime: new Date(Date.now() + this.windowMs),
    }

Now payload is always assigned a value

AAditya Mathur ?

Oh I see, you were asking for help. I thought you were saying you figured it out and wanted to let @Hello, I’m Allie! know how you fixed it.

I

Ian•7/2/24, 3:38 AM

I think your problem is your if statement. It has a semicolon before the

else

else

clause. Try the following

I

Ian•7/2/24, 3:39 AM

if (wasCreated) {
  payload = {
    totalHits: payload.totalHits + 1,
    resetTime: new Date(payload.resetTime),
  }; // <-- semicolon here
} else {  // <-- not here
  payload = {
    totalHits: 1,
    resetTime: new Date(Date.now() + this.windowMs),
  };
}

if (wasCreated) {
  payload = {
    totalHits: payload.totalHits + 1,
    resetTime: new Date(payload.resetTime),
  }; // <-- semicolon here
} else {  // <-- not here
  payload = {
    totalHits: 1,
    resetTime: new Date(Date.now() + this.windowMs),
  };
}

if (wasCreated) {
  payload = {
    totalHits: payload.totalHits + 1,
    resetTime: new Date(payload.resetTime),
  }; // <-- semicolon here
} else {  // <-- not here
  payload = {
    totalHits: 1,
    resetTime: new Date(Date.now() + this.windowMs),
  };
}

if (wasCreated) {
  payload = {
    totalHits: payload.totalHits + 1,
    resetTime: new Date(payload.resetTime),
  }; // <-- semicolon here
} else {  // <-- not here
  payload = {
    totalHits: 1,
    resetTime: new Date(Date.now() + this.windowMs),
  };
}

@Aditya Mathur are you sure you meant to use

expirationTtl

(seconds from now) ? Because I saw your

this.windowMs = 60_000 // 1 minute

this.windowMs = 60_000 // 1 minute

comment, but you also have

expirationTtl: this.windowMs

expirationTtl: this.windowMs

and that would be wrong; it would be 60000 seconds.

IIan @Aditya Mathur are you sure you meant to use `expiration` (seconds since the epo...

A

Aditya Mathur•7/2/24, 5:13 AM

Yeah, you are right about that but it is commented, so it is not getting executed. This is a rate limiter, so the problem is every time a user requests the server I have to update the

totalHits

totalHits

but the expiration time remains that same, thats why it is stored in

resetTime

resetTime

. So when I am updating it, I am passing the

expiration

expiration

again.

I

Ian•7/2/24, 5:14 AM

In the docs

As of January 2022, expiration targets that are less than 60 seconds into the future are not supported. This is true for both expiration methods.

I

Ian•7/2/24, 5:16 AM

@Aditya Mathur when you read the KV, doesn't it also contain the

expiration

expiration

attribute?

I

Ian•7/2/24, 5:17 AM

If so, just merge a default payload with a payload that it found...

A

Aditya Mathur•7/2/24, 5:18 AM

So what you are saying is, by updating the entry I am not overwriting the

expiration

expiration

?

I

Ian•7/2/24, 5:19 AM

yeah, don't bother updating expiration since it's basically "expires at Time", while the expirationTtl is "expires in X"

I

Ian•7/2/24, 5:20 AM

expiration is relative to a fixed point in time, the epoch. while expirationTtl is relative to right now.

I

Ian•7/2/24, 5:21 AM

so do this

have a default payload
get the KV
merge it with the default payload using spread operations
put the KV

A

Aditya Mathur•7/2/24, 5:22 AM

Is there a working example of using

WorkerKV

with

hono

which uses

expiration

expiration

or

expirationTtl

expirationTtl

?

I finally fixed the issue, the problem is with version 3.62.0 from wrangler, I downgrade it to 3.61.
