jsonlines simplifies working with newline-delimited JSON. It provides fast and efficient parsing and serialization for data where each line in a file represents a valid JSON object. Ideal for processing large datasets, streaming data, and log files, jsonlines ensures individual JSON payloads are handled correctly, preventing issues common with traditional JSON parsing on multi-line files. Its API is clean and easy to use, making it a great addition to any Node.js project dealing with high-volume JSON data.
The npm package jsonlines has seen very infrequent releases. It had one release in August 2015 (version 0.1.0) and another in June 2017 (version 0.1.1). Since then, there have been no releases, with all months from July 2017 through August 2025 showing zero releases.
Jsonlines npm package downloads show a fluctuating trend from March 2024 to September 2025. Downloads peaked in February 2025 at 3.1 million. While there was a general upward trend through early 2025, the last months show a decrease, with the current month of September 2025 having a very low amount of downloads due to the month not being over yet.
