⛽️ npm in Review: A Retrospective in Numbers

From Socket comes a look at the past year from the perspective of the npm registry, focused largely on statistics (2.5 million live packages!), including download numbers, popular packages, as well as some ‘quirky facts’ like the package with the most maintainers (554, if you're wondering.)

🌲 Tinybench: A Tiny, Simple Benchmarking Library

No dependencies, but uses whatever precise timing capabilities are available (e.g. process.hrtime or `peformance.now`). You can then benchmark whatever functions you want, specify how long or how many times to benchmark for, and get a variety of stats in return.

🌕 ✌️ I built my own Google (sort of...) with Text Transformers and Qdrant Vector Database

Building content search functionality for Next.js project almost always requires deep understanding of how the text similarity search works. Nowadays we have text transformer AI Models from HuggingFace and Vector Databases that easily could be integrated to Next.js giving the powerful similarity search functionality with a blasting speed! This video below explains this in detail.
