State of JavaScript 2025

Libraries

Libraries Experience & Sentiment

Vite has been the most-loved library for a few years now, but it has now overtaken React to also become the #2 most-used item, and seems ready to take the top spot next year.

Meanwhile, while Next.js is the 13th most-loved project, it's also the 5th most-hated, and generated the most comments overall–which goes to show just how polarizing the framework can be.

Changes Over Time

JavaScript libraries commonly display a "boomerang" pattern over time: boosted by early positivity (line goes right), usage increases (line shoots up), but users then get confronted with more edge cases and real-world issues, and opinions can become more negative (line veers left).

This means any project that moves to the right (such as Vue.js) or even just stays vertical (such as Astro) is worth paying attention to!

Each line goes from the earliest to the latest available year of data. A higher point means a technology has been used by more people, and a point further to the right means more users want to learn it; or have used it and would use it again.

  • Some lines skip years.
  • Technologies with only one year of data are not shown.
  • Velocity formula = (most recent opinion - oldest opinion) + (most recent usage) - (oldest usage)
  • A positive velocity means the usage and/or positive opinions have increased over time.

This chart ranks libraries based on their retention ratio (percentage of users who would use a library again). Note that libraries used by less than 10% of survey respondents are not included.

Ratios over Time

The prize for largest relative usage increase goes to Vitest and Playwright, which both gained 14 percentage points year-over-year.

Meanwhile, Rolldown saw a huge increase in name recognition, going from *33%% to 51% awareness. And when looking at satisfaction, Next.js experienced the largest drop, going from 68% to 55%.

Finally, it's also interesting to see that both Preact and React fare much better among respondents who have actually used them than those who have merely heard about the libraries (as shown in the Appreciation tab).

Retention vs Usage

With this year's inclusion of back-end frameworks, Express has joined Vite, React, and Jest in the coveted top-right quadrant. But Vue.js, Storybook, and Vitest are not far behind!

This chart shows each technology's retention ratio over its total user count. It can be divided into four quadrants:

  • ASSESS: Low usage, high retention. Technologies worth keeping an eye on.

  • ADOPT: High usage, high retention. Safe technologies to adopt.

  • AVOID: Low usage, low retention. Technologies probably best avoided currently.

  • ANALYZE: High usage, low retention. Reassess these technologies if you're currently using them.
