Eleventy Core Dependency Watch (2025 Edition)
In our quest for smoother long term maintenance and hardened security footprint, we wanted to let folks know that we’ve made even more exciting dependency simplification improvements on the v4 canary prereleases!
Notably when comparing v4.0.0-alpha.6 to v3.1.2, we’ve:
- Reduced our total dependency count from
134to105(21.6%) - Dropped third-party dependency count from
123to89(27.6%) - Decreased
node_modulesweight from21 MiBto14 MiB(33.3%)
