QUESTION
Have built myself a CLI tool for my more generic projects using Deno. It's useful, does the stuff I need it to do. However, I'm looking into achieving something similar to npm install -g
but with Deno.
I understand I could easily create a ~/.myDeno
with a bash script and adding export PATH=$PATH:~/.myDeno
but was wondering if there was a proper process to follow to achieve this with Deno. As I have thus far been unable to find one.

installs it the .deno
folder in your home directory and provides an PATH amendment you need to add to your bash profile.

Have created a multi-repo project. Aka each repo can execute seperately but also relies on other modules (which can also execute seperately) for specific tasks.
These are all stored in a private gitlab account/project/repo.
After doing some reading, it looks like GitLab don't support PA tokens for reading a private repo like Deno suggests.

QUESTION
I'm trying to make a mysql-based webapp based in Deno/Drash. A request comes in - it needs await a response from an sql query that is based on the path parameter - and then respond. When I try to await the query in the GET function it complains that I can't await in there (which makes sense) - is the best practice to then make the GET() function async?
...ANSWER
Answered 2021-Jun-02 at 01:38That is correct! Drash supports async HTTP methods and in your case, you would want to make your GET method async.

QUESTION
What is the optimal way of sharing linear tasks between worker threads to improve performance?
Take the following example of a basic Deno web-server:
Main Thread
...ANSWER
Answered 2021-May-26 at 16:43When working with WorkerThread code like this, I found that the best way to distribute jobs was to have the WorkerThread ask the main thread for a job when the WorkerThread knew that it was done with the prior job. The main thread could then send it a new job in response to that message.
In the main thread, I maintained a queue of jobs and a queue of WorkerThreads waiting for a job. If the job queue was empty, then the WorkerThread queue would likely have some workerThreads in it waiting for a job. Then, any time a job is added to the job queue, the code checks to see if there's a workerThread waiting and, if so, removes it from the queue and sends it the next job.
Anytime a workerThread sends a message indicating it is ready for the next job, then we check the job queue. If there's a job there, it is removed and sent to that worker. If not, the worker is added to the WorkerThread queue.
This whole bit of logic was very clean, did not need atomics or shared memory (because everything was gated through the event loop of the main process) and wasn't very much code.
I arrived at this mechanism after trying several other ways that each had their own problems. In one case, I had concurrency issues, in another I was starving the event loop, in another, I didn't have proper flow control to the WorkerThreads and was overwhelming them and not distributing load equally.

I'm trying to find the more information then available on the Deno 1.9 release notes, about the API of the native HTTP/2 server. My aim is to use server sent events (SSE) with the HTTP/2 server. The following code is available in the release notes:
...ANSWER
Answered 2021-May-04 at 19:50The API around Deno.serveHttp is actually quite basic, and is similar to the ServiceWorker fetch-event APIs which are documented on MDN.
Because the native HTTP server is still 'unstable', the Deno docs only show it in unstable mode. Here is a deeplink: https://doc.deno.land/builtin/unstable#Deno.RequestEvent
The summary is that you are given a Request object and are tasked with constructing/responding with a Response object. The MDN page on the Response constructor should be quite useful in showing the options you have when responding to a request.
This example shows a response with a body, status code, and one extra header:
