Morgan logger alternative in deno?

Playing around with some deno code and testing a npm import, the original package has types (redaxios) although when I import it it's not showing any intellisence in VS Code

Update value by reference without duplicating the data

Im exploring the world of FFI, porting some C applications I have to TypeScript, with the help of Deno. Currently, I cannot think of an efficient way to update the value that a pointer is pointing to. For instance, in C I could do something like: ```c char *array = calloc(2, sizeof(char)); if (array == NULL) return 1; *(array) = "hello";...

how to hash very large files

We have deprecated the old std/hash code in favor of the crypto module, but I do not know what the standard approach to hashing something piecemeal looks like. The advice around the crypto digest generally looks like this: ```ts async function crypto_hash(filepath: string) { const file_buffer = await Deno.readFile(filepath) const hash_buffer = await crypto.subtle.digest('SHA-256', file_buffer)...

Updating digest with web crypto

For some context, I'm updating some code that was importing from std/hash (specifically std/hash/sha256) to use std/crypto since the hash submodule is long gone. I've run up against a case where I'm not really sure what I should do to move forward. The code looks something like this: ```typescript const digest = new Sha256()...

Pass string to struct FFI

Quick question about Struct-Value feature, what would be the best way to pass *const u8 (or strings) to structs? I am kinda lost after reading the tests to get some examples running, here's what I got working so far : ```ts const lib = Deno.dlopen("./target/debug/libtest_struct.so", { add: {...

module augmentation

Suppose module.ts is some external module that I have no control of. In my file test.ts I want to change the type UserEnv of the external module. How can I do this or does Deno just not support this and you basically need to use node to do this? ...

Looking to chunk the HTML stream on the homepage to reduce initial page load. Are there good docs?

I'm currently reading and transforming every markdown file in the render function and i'd like to instead yield chunks of markup so the browser can get started rendering sooner. is there a paved path for me in fresh? thanks!

Rewind streams

So I'm using web streams (byob) for a project but in some cases I need to peek ahead. Is it possible to do this with webstreams? I want to read a static amount of bytes and then rewind by n bytes (between 0 and 4)...
