title: revalidateTag Single Argument Deprecated
|
|
---
|
|
|
|
## Why This Error Occurred
|
|
|
|
You are using `revalidateTag` without providing the second argument, which is now deprecated. The function now requires a second argument to specify the revalidation behavior.
|
|
|
|
## Possible Ways to Fix It
|
|
|
|
### Option 1: Add the second argument
|
|
|
|
Update your `revalidateTag` calls to include the second argument `"max"`:
|
|
|
|
```js
|
|
// Before (deprecated)
|
|
revalidateTag('posts')
|
|
|
|
// After
|
|
revalidateTag('posts', 'max')
|
|
```
|
|
|
|
### Option 2: Use updateTag in Server Actions
|
|
|
|
If you're calling this from a Server Action and need immediate expiration for read-your-own-writes, use `updateTag` instead:
|
|
|
|
```js
|
|
// In a Server Action
|
|
import { updateTag } from 'next/cache'
|
|
|
|
export async function createPost() {
|
|
// ... create post ...
|
|
|
|
// Immediately expire the cache
|
|
updateTag('posts')
|
|
}
|
|
```
|
|
|
|
## Revalidation Behavior
|
|
|
|
- **`revalidateTag(tag, "max")` (recommended)**: The tag entry is marked as stale, and the next time a resource with that tag is visited, it will use stale-while-revalidate semantics. This means the stale content is served while fresh content is fetched in the background.
|
|
|
|
- **`revalidateTag(tag, profile)`**: For advanced usage, you can specify any cache life profile that your application has defined in your `next.config` instead of `"max"`, allowing for custom revalidation behaviors.
|
|
|
|
- **`updateTag(tag)`**: Only available in Server Actions. The tag entry is expired immediately, and the next request to that resource will be a blocking revalidate/cache miss. This ensures read-your-own-writes consistency.
|
|
|
|
- **`revalidateTag(tag)` without second argument (deprecated)**: Same behavior as `updateTag` but shows this deprecation warning.
