Bundlephobia | Size of npm dependencies
What does Bundlephobia do? JavaScript bloat is more real today than it ever was. Sites continuously get bigger as more (often redundant) libraries are thrown to solve new probl ems. Until of-course, the big rewrite happens. Bundlephobia lets you understand the performance cost ofnpmÂ install ing a new npm package before it becomes a part of your bundle.
