Deno

FIRST-HAND READS

What people reported, in their own words. Every line links to where it was said.

• “it's generally better to augment Deno to pass for Chrome and fool all the checks and their future versions then to just break a single check that may change soon”

  POSITIVE · features · Hacker News · 2026-07-10

• “I don't think Deno will be able to upgrade until the TypeScript compiler API is ready”

  NEGATIVE · features · Hacker News · 2026-07-08

• “It's just the discrepancy between not needing the newer version of vite/node on bun while invoking an error using deno. Feels like I should have either gotten perfectly matching versions, or error messages (with commands) to update node.”

• “I'd still bet on Deno in the long term, and I personally still use it for any .ts projects”

  POSITIVE · features · Hacker News · 2026-06-25

• “Deno does genuinely have good parts: built-in type checking, LSP server, formatter with sane defaults, and so on.”

• “Deno continues to impress me. It's honestly been quite a while since I started a new project without it. It has fully won my support over Node.js, the ecosystem has really matured nicely.”

• “error: Module not found "file:///D:/source/DenoTest/desktop"”

  NEGATIVE · reliability · Hacker News · 2026-06-22

• “deno hello2.tsx error: Uncaught (in promise) ReferenceError: React is not defined”

  NEGATIVE · performance · Hacker News · 2026-05-23

• “racking up a huge deno deploy and vercel bills ($40-50/mo each)”

  NEGATIVE · price · Hacker News · 2026-05-03

• “it uses Deno as the runtime to constrain network, filesystem, environment, and other types of access at runtime as needed”

  POSITIVE · features · Hacker News · 2026-05-03

• “the one great thing about Deno is that it can directly import without requiring a 'manifest file'”

  POSITIVE · features · Hacker News · 2026-01-28

• “using Deno's built-in tooling (fmt, lint, check, test) instead of fighting with build configs has been refreshing”

  MIXED · features · Hacker News · 2025-10-29

• “Deno's LSP is also sometimes preferred for being a single Rust binary that runs quicker than Typescript's not-quite-LSP”

  POSITIVE · performance · Hacker News · 2025-09-24

• “I mostly like its typescript "required" opinions (I don't configure it much beyond its out of the box configuration). You can use `deno lint` just fine even if you aren't using deno as a runtime.”

  POSITIVE · features · Hacker News · 2025-07-17

• “The API site is sent to Deno Deploy, using Deno KV as the database, and using Deno Queues for the vote calculation work which is probably overkill for the club's current scale but the engineering effort behind it felt like a good idea and makes me happy”
