kandi X-RAY | node-dir Summary
You ever used Firebug? You know the awesome dir function its console has? Well, this is like that, but for Node. That means you get real object inspection that goes up the prototype chain, not the pansy-ass, weak-sauce "inspection" Node’s util.inspect gives you. And it actually returns an object instead of a string, so you don’t have to tediously and explicitly console.log it in the shell to unescape characters. And best of all, since it returns a real object, the output is just as nicely colored and formatted as the native shell. Btw, it turns out Node already has a console.dir, but, uh… it doesn’t seem any different than console.log! So this monkey-patches it to no longer suck.

Answered 2020-Aug-14 at 03:46You don't need ::: if there's nothing after it, and {} is pointless too if you don't have any sources. Without more information about what exactly you would want to parallelize, we can't really tell you what you should use instead.
But for example, if you want to run one find in each of /etc, /usr, /bin, and /opt, that would look like

QUESTION
I tried to use the node-dir module from Nodejs to read files from a directory, after all files are read I then send them to Redis, and finally shutdown the Redis connection, so I used Promise. However, the quitting connection to Redis line always gets to executed first, the "then" clause doesn't seem to wait till the Promise resolves, leading to connection being shut down before any persisting happens, may I seek your help?

QUESTION
I'm building a NodeJS application on Docker in Swarm mode (single node). I'm using bind mount volume for NodeJS source code. Everything runs perfectly and I can see the output in localhost from NodeJS and Express, but when I change something in NodeJS code (which is in a bind mount volume), nothing changes. I have to restart my service to observe the changes. Earlier when I was working with Docker Compose only, it never happened, but now when I have switched to Swarm, I'm experiencing problems.
I'm using Docker 18 with Visual Studio Code 1.39 on macOS 10.14.6
Dockerfile
...ANSWER
Answered 2019-Oct-23 at 17:36If your volume mapping is correct, the source code changes should reach your node.js app container.
You can verify it by inspecting the source code inside the container after you make a change on docker host.
I'm currently in development mode, and I have to test the source code repeatedly so I want to use bind mounts to make development and testing easier.
However, your source code change won't be effective until node process inside the container reloads and picks up the changes.
In order to achieve this you have to use nodemon. Nodemon will pick the changes in the source code and reload node process along with the changes.
Another, longer alternative would be building new docker image and then updating your app using: docker service update --image=...

QUESTION
There are a number of options for traversing a directory tree in Javascript (node-dir, fs.readdir, ...) and most supports asynchronous execution with a callback when finished.
But is there a framework that supports callbacks on each found file? I want to build a loader for audio files that incrementally adds the files as they are found.
Plain Javascript (or Typescript) solutions are also accepted.
...ANSWER
Answered 2019-Feb-05 at 20:21I was thinking that traversing the structure was costly, and wanted to do the work for each file as it was found by the traversal, instead of collecting a list first. But experiments show that this is not the case, traversal is in fact very cheap compared to just opening a file, let alone parsing content. So I'll go with the suggestion from @Joseph and just use one of the options listed and call the function for each file.
I'll make this incremental by doing this asynchronously and update the UI reactively.
Thanks, for straightening out my thinking.

QUESTION
I obtained the code below from the NPM package node-dir, The code works fine as it reads a directory and than reads each file in the directory and spits it back out to the console. What I really want is for it to be sent with JSON.stringify so I can than perform an ajax or $.getJSON call to render it to the UI so I can build reports from the data.
I get where the issue is, the files argument is inside of the second functions scope. So when I try to perform the req.send with files it says files is undefined. If I try to put req.send inside of the function it will say req is not defined, or if I pass in req as an argument it will say req.send is not a function because the function is stored with in router.get.
Im hoping for a simple solution with the current code or is there a better approach? I believe it may have something to do with .apply() or possibly some kind of callback or promise maybe? Sorry im still a noob with this kind of functional programming.
