Interesting tools

Each week we review 2—3 of the most interesting developer tools. Here's what we featured this week.

Watt

Node.js application server.

What we like

Uses SO_REUSEPORT built into the Linux kernel for connection distribution, eliminating significant overhead. Handles crash restarts, graceful shutdown, monitoring, deployments for multiple applications. Shared HTTP cache across workers. Allows integration of databases, APIs, and multiple frameworks within a single app server.

What we don't like

Supports observability through Prometheus and Jaeger, but needs extra work to get data into services like DataDog unless you ingest through OTLP.

Renovate

Automated dependency updates.

What we like

Creates pull requests for dependency updates from auto-discovered packages. Designed as a more configurable replacement for Dependabot. Can create a “dashboard” tracking issue to easily see pending updates and manage them (individually or as a group). Supports most popular forges, not just GitHub. Run it independently through CI, not just as a hosted service.

What we don't like

Seems to be gradually being absorbed by an enterprise cloud platform (Mend).
