fetch-blob is a lightweight, browser-compatible implementation of the Blob and File APIs, enabling easy creation and manipulation of binary data within web environments. It's particularly useful for situations where native Blob support is limited or inconsistent. Its core focus is simplicity and efficiency, streamlining the process of constructing and handling binary data for purposes like uploading files or manipulating images directly in the browser, making it a valuable tool for enhancing web application functionality.
Fetch-blob's downloads show a strong upward trend from March 2024 to August 2025, growing from ~13 million to ~51 million. September 2025 data is incomplete, showing significantly lower downloads (~17 million) as only part of the month is accounted. The package experienced notable growth throughout 2025.
The fetch-blob npm package had frequent releases between 2019 and 2022, with multiple versions in some months. Release frequency significantly decreased after July 2022, with only one release in May 2023 (version 4.0.0). There have been no releases since May 2023, and none so far in 2025.
