We're highlighting interesting features or libraries we think you should know about.

Library Highlight: ElysiaJS

There are many back-end frameworks around, but Elysia stands out as the only one being built on top of Bun.

Leveraging a brand new runtime can be a risky bet, but given Bun's own growing popularity it looks like that bet might pay off. If anything, it's certainly proving to be an interesting experiment!

Back-end Frameworks Ratios Over Time

After three years of absence from the survey, it was high time we checked back on back-end frameworks. And no surprise here, Express is still the leader in terms of usage, even if Nest is progressing at a nice clip.

But things are more interesting when switching to the Satisfactiont tab, where the top three projects (Hono, Nitro, and ElysiaJS) are all new entrants, making this once of the most exciting categories to watch in years to come.

Other Back-end Frameworks

oRPC offers typesafe APIs, which is a big selling point compared to traditional back-end solutions created before the TypeScript sea change.

We asked members of the JavaScript community to share their “pick of the year”

My 2025 Pick: The Atproto Dev Community

I think the atproto dev community deserves a spotlight - one of the official SDKs is TypeScript! Also shout-out to Jason Lengstorf and everyone else involved in this.

Number of Items

Respondents tend to use relatively few back-end frameworks, which might be why Express remains so dominant: once you've picked a back-end, you're unlikely to go out of your way to try out new options.

Back-end Frameworks Pain Points

While *Express is still widely used 15 years after its initial release, some are starting to wish the back-end ecosystem would move on to more modern alternatives.

This is especially true when it comes to providing typesafe, TypeScript-compatible APIs, which is something that venerable framework was never meant to do.
