Why does `deno test` add an older version of the `std` library to my deno.lock?
My testing files do not reference
std/0.165 and my import-map.json is pinned to std/0.177. When I use deno run everything works fine. When I use deno test for some reason std/0.165 is added to my deno.lock file and then I get errors about core.runMicrotasks is not a function.
How do I keep deno test from adding an older version of std to the deno.lock file?...package.json support not working for prisma

FFI Difference between buffer and pointer
I’ve been using interchangeably
Deno.UnsafePointer.of(new Uint8Array()) with type pointer and new Uint8Array() with type buffer. Is there any major difference? Per se I don’t use char[] arrays, just pointers.Detecting invalid JS strings
Is there any built-in way to "detect" invalid strings?

Cache related headers not included in deno deploy for static file serving
I have a hello world level static site using
serveDir. When I run the site locally I see that Weak E-Tag headers are included in responses for the static files and can verify in dev tools that caching works.
When I deploy the site with deno deploy I don't see any caching and each request sends the full response to the browser. I can see that compression is running as described in the caching documentation but the docs seem to suggest that if Weak E-tags are included (which I assume is the case since that is how serveDir is behaving locally) that I would expect them in the responses.
- Any ideas on why deno deploy is not including caching headers in responses?...Error with relativ import path after "deno install"

Suggestions for minimal JSX rendering?
Any suggestions for rendering jsx to a string (or ideally a stream), in the most minimal manner from Deno? I'm currently using preact and preact-render-to-string, but i feel that may just be a bit overkill. I don't need client-side, hooks, or any other preact/react features.
Deno.run Strange Issue
I use
Deno.run + stdout/signals/etc a lot, but this behavior is beyond my current debugging abilities
I have a command nix eval ... which works fine in a python subshell, and on the commandline. However, Deno.run with piped stdout makes it hang indefinitely. To be explicit, in this block: process.status().then(callback).catch(callback) the callback doesn't run until a .kill() is used (SIGHUP/SIGINT/SIGKILL). Tested on Deno 1.29.4 and Deno 1.22.0 for good measure.
What is even more strange is trying to bypass the problem with hackery also fails....Properly continuously read data from a Reader
What's the proper way to continuously read from a
Deno.Reader?
I'm trying to parse incoming HTTP2 frames from a Deno.TlsConn, but my current method of reading involves two sets of while loops, one to continuously perform the read operation, and the other, to try read everything currently available to read from the stream in chunks of 16k.
Naturally, the while loops make it take approximately one entire core of my processor, which is far from ideal.
...npm:redis – everything returns `string`?
Every command I try to use from

Is it possible to compile my app with additional files? Or, setup a config location it looks for?
I'd love the former, will settle for the latter. I found Leaf, but it doesn't seem to work.
