I need a practical example for SWR with the fallback option
I'm trying to understand better how SWR works paired up with NextJS. I have over studied the example shown in the SWR - Next.JS SSG and SSR tab, but I am still confused as how to get the data from an external API:
Why does the example from the hyperlink above uses '/api/article' as a key?
Is the useSWR hook going to grab this key and navigate to this destination?
Can I use an external API response such as "https://jsonplaceholder.typicode.com/posts"?
What do I put as a value inside the fallback object?
This is a simple snippet that I used to tinker with the fallback option. I do get a 1/4th of a second view of the data being displayed in the browser and it goes away turning into "John Doe".
import useSWR from "swr"
const fetcher = (...args) => fetch(...args).then(x=>x.json())
export default () =>{
const {data, error} = useSWR("/api/hello", fetcher, {fallback:{"/api/hello":{name:"foo bar" }}})
console.log(data)
return {data && data.name}
}
I would like to see some other use cases where this feature would come in handy. If there's a link that I could get in order to understand this feature better, then that would be very beneficial to me.
I also tried to explain in my words to see if there is a mistake in my knowledge and I could be corrected if my logic is wrong.

Can element be a parent of a control?
In a scenario, a parent of a control is responsible for performing & parsing data requests. However, it has no real DOM; the parsed data is for it's children only.
For the parent, one could use core.Control and do a simple render wrap around the children, but my question is, can core.Element be used for the parent & skip the unneeded render step for it, while still rendering its children?
Thanks

Best practice for code-completion after retrieving an Eloquent model using Model::first()
I recently read (and now I can’t find it) an article that claimed it was bad practice to use a DocBlock comment to typehint the return value of Model::first(). If I recall, the article was a code style guide used by a project.
Does anyone happen to know what article I’m talking about?
Here’s the specific thing I recall. They claimed that this was not best practice: /** @var User $user */ $user = User::first();
There was something else they did that allowed the IDE to know that $user was a User type.
Without the comment, my IDE (PhpStorm) can’t do any code-completion for my $user object. Is there something I should be doing so the IDE recognizes $user as a User besides this comment?
Thanks for any help!
Edit: I have the Laravel Idea plugin enabled, and I also use the ide-helpers plugin, but PhoStorm still doesn’t recognize the model in my example. submitted by /u/mtmo

Telegraf save only last line of csv input
I have a script that print a result like that:
somename,bps,running_time
AAA,1886,01:35
BBB,6235,01:35
CCC,2532,01:35
Here is my telegraf config :
[[inputs.exec]]
commands = [ "bash /opt/latency/test.sh" ]
timeout = "5s"
name_override = "latency"
data_format = "csv"
csv_header_row_count = 1
csv_trim_space = true
csv_column_names = ["somename","bps","running_time"]
csv_column_types = ["string","int","string"]
csv_skip_errors = true
csv_comment = ""
csv_skip_rows = 0
When I check on grafana which variables are put on the influxdb, there is only the last line aka with somename=CCC.
How can I add three lines into influxdb and not only last one?

Remix.run useLoaderData returns type any
I was just trying this new thing remix.run and came across this. Everywhere in cos for this framework they are using const data = useLoaderData() to have type of data variable inferred. But for me this is not working:
import { json } from "@remix-run/node";
import type { LoaderFunction, LoaderArgs } from "@remix-run/node";
import { useLoaderData } from "@remix-run/react";
import { getUsers } from "~/models/users.server";
export const loader: LoaderFunction = async (args: LoaderArgs) => {
const users = await getUsers();
return json({ users: users });
};
export default function Users() {
const { users } = useLoaderData();
return (
{users.map((u) => (
{u.username}
))}
);
}
My VSCode says that variable users has any type and there is a squiggly line red line bellow u in map...what is wrong?
package.json:
"@remix-run/css-bundle": "^1.16.0",
"@remix-run/node": "^1.16.0",
"@remix-run/react": "^1.16.0",
"@remix-run/serve": "^1.16.0",

Database revision vs Event sourcing for tracking changes of entity changes
We are developing a platform where there is the possibility of booking hotels. The booking process can consist of various operations: creation, change of dates, cancellation, confirmation, and so on. We need to have access to the history of booking changes to display this on the front end (for now, only for displaying, who knows what might happen in the future).
One of the ways to use this history of changes: Created a booking -> changed the dates -> we show the user the previous dates and current ones.
The entity of Booking: { checkInDate: string, checkOutDate: string, amount: number ... +30 fields }
Found two approaches:
First approach: Versioning the entity at the database level.
If our entity is updated, then a copy of the entity is automatically created, but with new fields. In the case of changing the dates of a just created booking, the client will return an array of bookings, each will have all the fields of the booking and an additional field with the status (created, changed dates etc).
Pros of this approach:
*
Faster backend implementation, changes are mostly required at the database level.
*
One familiar Booking model is used.
*
Ability to configure rollbacks.
*
Good performance.
Cons:
* Difficult to set up auto migration.
* The database stores a lot of excess data, which will be returned to the client who does not need them.
Second approach: Event-driven architecture
There is a described list of possible events that can occur with a booking. An event is created for each operation, which can contain a payload with the data that has changed. In the case of changing the dates of a just created booking, the client will return a booking with an array of events, each of which contains a list of data that has changed. The changed-dates event may contain the previous dates and current ones.
Pros:
*
Only necessary data is stored in the database and returned to the front.
*
Having a list of described events, the flow becomes transparent, which improves the understanding of the code.
*
In the event payload, you can add any data, even those not related to the previous booking change. Easier to expand functionality.
*
Business logic is kept on the backend, the front simply displays the data, business logic does not penetrate the database level.
Cons:
*
Many additional types are added, which need to be used on the front.
*
More complex backend implementation.
Could you suggest which solution is better to choose? Maybe you have a better option?

How would you structure a system with multiple bussiness "regions"?
For example, an e-commerce site, where there are a "region" for the sellers, with feature align to managing products or selling analytic. And a front-facing "region" for regular clients to browse the products, have a cart, bookmark or follow products or brands.
When there are 2 (or more) distinct regions for different functionality and client. How would you structure your Laravel project? Would you follow DDD? Microservices? Or something else?
To be clear it is not strictly e-commerce, but any systems that had multiple regions like that. A travel agency where there are region for hotel owner to register and manage their hotel versus a region for everyone to search and book hotel. A streaming app where everyone can browser their favorite streamer but the streamers have their own managing place as well as analytic... Also count submitted by /u/Lumethys

VBA download file from website - popup window
I am trying to automate a file downloading from a website. When I do the download manually, all I have to do is to click on the "save" icon (floppy disk), then another window pops up for a second and the download begins (while the popped up window disappears).
What I usually do (when I automate a download) is to find the files URL, then I use the URLDownloadToFile function. But in this case I cannot find the url in the html. I tried to use the .click and FireEvent on the object but nothing worked.
So I started to think (based on similar question in this site) that a script generates the URL when I press the "save" icon. Unfortunately I am not familiar with javascript or how it works. Right now I am trying to use my browser's developer tools's console to figure out what happens when I click the object. BTW: this object is an object.
I searched the web for answers, and I think that somehow I will have to call the javascript myself if I want to download the file, with something like execScript. But how do I find out which script gets called when I click on the icon? And more importantly will I be able to understand your answer without completely understanding how a webpage works? :)
P.S.: I know it would be far easier if I could give you the site address, but it requires a login to see the stuff that I am talking about...

Small but powerful CLI apps with Minicli
Minicli is a lightweight PHP structure for building order line applications. While it gives a moderate methodology, you can in any case make strong CLI applications with it. Here are some little yet strong CLI application thoughts that you can carry out utilizing Minicli:
Schedule Director: Make an order line application that permits clients to deal with their errands and plans for the day. Clients can add undertakings, mark them as finished, erase errands, and view their rundown.
Climate Correspondent: Foster a CLI application that gets climate information from a climate Programming interface in view of client input (e.g., city or Postal division). It can show current atmospheric conditions, figures, and other important data.
Document Coordinator: Fabricate a CLI application that sorts out records in a registry in light of their sort, expansion, or different models. Clients can determine the source and objective catalogs, and the application will move or duplicate documents in like manner.
Secret phrase Generator: Make a CLI application that produces solid, irregular passwords in view of client characterized models like length, consideration of extraordinary characters, or explicit person sets.
URL Shortener: Foster a CLI application that interfaces with a URL shortening administration Programming interface to abbreviate long URLs and give an abbreviated variant to more straightforward sharing.
Word Counter: Form a CLI application that takes a text document or contribution from the client and counts the quantity of words, characters, lines, or other pertinent insights.
ASCII Workmanship Generator: Foster a CLI application that changes over a picture or text input into ASCII craftsmanship. Clients can determine the information record, textual style, and other customization choices.
Markdown to HTML Converter: Make a CLI application that changes over Markdown documents to HTML. Clients can indicate the information record and alternatively tweak the result document area and arrangement.
Keep in mind, these are only a few guides to kick you off. With Minicli, you have the adaptability to make different sorts of order line applications in view of your particular prerequisites. You can use the effortlessness and extensibility of Minicli to fabricate little yet strong CLI applications custom fitted to your requirements.
Here new way ....
Building CLI applications can be a lot of fun. We don't have to worry about the UI, and we can write beautiful PHP code that doesn't need any build steps.
When building CLI applications in PHP, we aren't as spoilt for choice as in building web applications - but there are some solid contenders. From using the defacto standard Symfony Console component or the extra spicy Laravel Zero. However, when building a CLI application, you may want to be as dependency free as possible - which is where Minicli comes in. Minicli was released a while ago by Erika Heidi as an experiment to build a dependency-free CLI framework that leaned on PHPs readline extension as its only dependency.
I have been spending a lot of time investigating CLI options for a project I am working on. At first, I started with my usual choice: Laravel Zero. It is familiar to me and any other developer who knows Laravel. Then I started questioning the portability aspect and requiring PHP for people who want to use it. This is for work, and not all of our users have PHP installed. So I dived into the world of compiled languages, looking at both GoLang and Rust. While there aren't many options available, the options out there are excellent.
There has been a lot of talk about native PHP recently, which drew my attention back toward the PHP space. What if I could build a lightweight, easy-to-maintain, and portable PHP CLI application? This was when I took another look at Minicli. Having played with it when it first came out, I was impressed with how nice it was to use for something dependency free - but also how easy it was to get started!
The recommended approach for building a Minicli application is to use the application skeleton and composer to set everything up and ready for you.
composer create-project --prefer-dist minicli/application my-awesome-ideaThe directories should be familiar enough for you as Laravel developers, having an app directory and namespace. The commands you can create are recommended to be built as Command Controllers, which are class-based commands.
We create a command namespace under app/Commands, where you keep your commands.
mkdir app/Commands/LaravelNewsUnder each namespace, you can add multiple commands for different variations. It is inferred that if no arguments are passed, you will want to use the DefaultController. Let's have a look at how to create a command.
declare(strict_types=1); namespace App\Command\LaravelNews; use Minicli\Command\CommandController; final class DefaultController extends CommandController{ public function handle(): void { $this->getPrinter()->display("Laravel News rocks"); }}Each command controller must be handled and doesn't have to return anything - unlike in Symfony or Laravel Zero, where an exit code is expected. To interact with output, you get the printer - and ask it to output something.
So, if we want to add an alternative version - we can create another command controller in our namespace.
declare(strict_types=1); namespace App\Command\LaravelNews; use Minicli\Command\CommandController; final class InfoController extends CommandController{ public function handle(): void { $this->getPrinter()->info("Laravel News rocks"); }}Now we can call our command:
./minicli laravel-news infoWhich will give a different view to the default command, and we can use the following other options:
display(): A simple text output.info(): An informative text output.error(): An error formatted text output.success(): A success formatted text output.
Each option accepts a second argument as alt for alternative output, which will do a block color output with writing instead of colored writing.
It isn't as pretty as something like Laravel Zero using Termwind - but sometimes you don't need pretty!
Usually, when building a CLI application, we want to interact with a third-party API or another service to perform an action or logic. In Minicli, this is done by creating services.
// minicli$app = new App();$app->registerService( 'email', new MyEmailImplementation(),);Then within our commands, we can get the app instance and call our service directly:
public function handle(): void{ $service = $this->getApp()->email; try { $service->send(new EmailTemplate()); } catch (Throwable $exception) { $this->getPrinter()->error($exception->getMessage()); }}So we have a lightweight, powerful CLI framework that we can leverage to aid in our development workflow - that has no dependencies allowing us to write beautiful PHP.
