Please check the Cloudflare KV bindings, the KV environment variable name should be all uppercase letters.
Please check if NUXT_SITE_TOKEN is set to pure numbers, Sink does not support pure number Tokens, we consider this to be unsafe.
Analytics data requires access to Cloudflare’s settings:
- Verify
NUXT_CF_ACCOUNT_IDandNUXT_CF_API_TOKENare configured correctly (ensure the Account ID matches the deployment zone ID). - Check that the Worker analytics engine is enabled.
Of course. Please set the environment variable NUXT_HOME_URL to your blog or official website address.
NuxtHub's ANALYTICS points to its dataset, you need to set the NUXT_DATASET environment variable to point to the same dataset.
This is a feature of Sink. By default, we automatically convert all links to lowercase to avoid case-sensitive issues and improve usability. This ensures users don’t encounter errors due to accidental capitalization differences.
However, you can disable this feature by setting the NUXT_CASE_SENSITIVE environment variable to true.
Newly generated links will be case-sensitive, treating MyLink and mylink as distinct. Randomly generated slugs will include both uppercase and lowercase characters, offering a larger pool of unique combinations (but not user-friendly that why we default to non-case-sensitive).
To improve query performance, we have limited the amount of data. If you need to query more data, you can adjust it through NUXT_LIST_QUERY_LIMIT.
Set NUXT_DISABLE_BOT_ACCESS_LOG to true.
Import and Export are designed to work within Cloudflare Workers' KV operation limits (50 per request by default).
- Export: Downloads links in batches, automatically paginating until complete.
- Import: Uploads links in batches (half of
NUXT_PUBLIC_KV_BATCH_LIMIT, default 25) since each link requires 2 KV operations (check existence + write). - Expired links: Imported as-is to support migration scenarios.
- Duplicate slugs: Skipped during import (existing links are preserved).
- Validation: All links are validated against the schema before import starts.
