Showing Direction Arrow on Line in Mapboxgl

Trying to show a arrow as indication of direction in mapboxgl. The arrow is only visible at high zoom and is not visible at low zooms.



Adding a image Layer with 'symbol-placement': 'line'



Line Layer

map.addLayer({
'id': 'route',
'type': 'line',
'source': 'mapSource',
'filter': ['==', '$type', 'LineString'],
'layout': {
'line-join': 'round',
'line-cap': 'round'
},
'paint': {
'line-color': '#3cb2d0',
'line-width': {
'base': 1.5,
'stops': [[1, 0.5], [8, 3], [15, 6], [22, 8]]
}
}
});




Arrow Layer

const url = 'img/arrow.png'
map.loadImage(url, (err, image) => {
if (err) { return; }
map.addImage('arrow', image);
map.addLayer({
'id': 'arrowId',
'type': 'symbol',
'source': 'mapSource',
'layout': {
'symbol-placement': 'line',
'symbol-spacing': 1,
'icon-allow-overlap': true,
// 'icon-ignore-placement': true,
'icon-image': 'arrow',
'icon-size': 0.045,
'visibility': 'visible'
}
});
});




No Arrow at low zoom







Arrow showing at high zoom







I have tried experimenting with symbol-spacing, but it didn't work.
Is there way to force mapbox to show arrow on low zoom?

GCP static website hosting via bucket does not serve configured error and index pages

I'm trying to serve a simple static React SPA through GCP bucket as described here:

In the folder test_2023_11_03_c there is a file "index.html"


But it doesn't work.


For

PHP Input Stream Truncated at 8192 bytes

I'm working on a project on Symfony 3 as an API and Angular as a front (This is not relevant i think but hey).



When some datas are sent through a PUT request to the server, the data are truncated at 8192 bytes.



I checked for every file configurations (apache files, even cli file, .htacces file... but can't seem to find the issue.)



Weirdest thing, is the issue is on the dev server, the same request on the production server works (all the 18 000~ bytes are sent correctly), so i even tried to take the production server's php configuration file, but even that failed. Just to add on the information, the server runs on php 7.



I'm at a loss, what could i have missed ?



I'm pretty sure the issue comes from a configuration file, or a knowledge i'm missing. So help would be greatly appreciated.



Thanks.



Edit: After a bit of forcing... Here is a .tar.gz containing the files requested:

7 Tips for Adding a Second Server to your App

---



Adding a second server to your app can be a great way to improve your app's performance and/or increase its reliability. However, there are a couple of things you need to keep in mind when adding a second server.


In this article, we'll discuss the key things you need to consider when adding an additional server to your app. We’ll use a Laravel hosted in Laravel Forge as the example here, but the concepts can be applied to any kind of application, not even limited to the PHP language.


Current infrastructure




First, to make sure we are speaking the same language, this is the outline of the current infrastructure. This app is currently running on a server created by Laravel Forge and running on AWS.



* Lets Encrypt for the SSL certificate;

* Redis (installed on the machine) for sessions, caching and as the queue driver for storing and processing background jobs;

* MySQL (installed on the machine) as the database;

* Local folder for saving user uploaded content;

* Laravel Scheduler using server’s CRON every minute;

* Deployments are manually triggered by clicking Laravel Forge’s “Deploy now” button;






1. Load balancer




The first thing you will need is a load balancer. This will be the entrypoint of your application, meaning you will point your domain DNS to the load balancer instead of the server directly. The job of a load balancer is, as you guessed, to balance the incoming requests between all the healthy and registered servers.





From now on, every time we mention “App Server”, this will be referring to a single server running our Laravel application.


One of the nice features of a load balancer is the health checks, which serve the purpose of making sure that all connected servers are healthy. If one of the servers fails for some reason, some unscheduled maintenance for example, the load balancer will stop routing requests to that server until the server is up, running, and healthy again.


We recommend using the application load balancer, which gives more robust functionality down the road, if you need it. Application load balancers can route traffic to specific servers based on the requested URL and even route requests to multiple applications. For now, we will have it evenly balance traffic using the round robin method.


Since your domain will now be pointing to the load balancer, your SSL certificate should also be in the load balancer now, instead of in your servers.


2. Database (MySQL), cache & queue (Redis)




Currently, there is one server running our app, local instances of MySQL, and Redis. What happens when the second gets attached to our load balancer?


Having multiple sources of truth for our database and caching layers could generate all kinds of issues. With multiple databases, the user would be registered in one server but not the other. With one Redis instance per server, you could be logged in into App Server 1, but when the load balancer redirects you to App Server 2 you would have to sign in again, since your session is stored in the local Redis instance.


We could make App Server 2, or any future App Servers connected to our load balancer, connect to App Server’s 1 services, but what happens when App Server 1 has to go down for maintenance or it unexpectedly fails? One of the reasons to add a second server is to have more reliability and scalability, which does not solve our problem.


The ideal scenario, when we have multiple app servers, is to have external services like MySQL and Redis running in a separate environment. To achieve this, we can use managed services, like AWS RDS, for databases and AWS Elasticache for Redis or unmanaged services, meaning we are going to set up a separate server to run those services ourselves. Managed services are usually a better option if cost is not an issue since you don’t have to worry about OS and softwares upgrades, and they usually have a better security layer.


Let’s imagine we decided to go with managed services for our application. Our Laravel configuration would become similar as this:
-DB_HOST=localhost
+DB_HOST=app-database.a2rmat6p8bcx7.us-east-1.rds.amazonaws.com
-REDIS_HOST=localhost
+REDIS_HOST=app-redis.qexyfo.ng.0001.use2.cache.amazonaws.com



After everything is set up, our infrastructure would look like this when connecting our App Servers to our services.





3. User uploaded content




Our application allows users to upload a custom profile picture, which shows up when you are logged in. On our current infrastructure, images get saved in an internal folder in our application and also get served from there. Now that we have multiple App Servers, this would be an issue, since the images uploaded in the App Server 1 will not be present on the second server.


There are a few ways to solve this. One of them is to have a shared folder between your servers (Amazon EFS, for example). If we choose this option, we would have to configure a custom filesystem in Laravel which would point to this shared folder location on our App Servers. While a valid option, this requires some knowledge to set up the disk on the servers, and for every new server you set up, you would have to configure the shared folder again.


We usually prefer using a Cloud Object Storage service instead, like Amazon S3 or Digital Ocean Spaces. Laravel makes it really easy to work with these services, if you are using the File Storage options. In this case, you would only have to configure your filesystem disk to use S3, and upload all your previous user uploaded content to a bucket.
-FILESYSTEM_DISK=local
+FILESYSTEM_DISK=s3 

AWS_ACCESS_KEY_ID=your-key
AWS_SECRET_ACCESS_KEY=your-secret-access-key
AWS_DEFAULT_REGION=us-east-1
AWS_BUCKET=your-bucket-name



All your user uploaded content will be stored in the same, centralized bucket. S3 has built in versioning, multiple layers of redundancy and any additional app servers we add to our load balancer can use the same bucket to store content.





If your application grows in the future, you can set up AWS Cloudfront, which acts as a CDN layer sitting on top of your S3 bucket, serving your bucket content faster to your users and often cheaper than S3.


4. Queue workers




In step 2, we set up a centralized Redis server, which is the technology we were using to manage our application queues. This will also work for our load balanced applications, but there are a few good options to explore.


If you continue to process your queues on your app servers leveraging the centralized Redis instance, no changes need to be made. The jobs will get picked up by the server that has a worker available to process a job.


Another option is to use a service like AWS SQS, which can relieve some pressure on your Redis instance as your application grows by offloading that workload to another service.


5. Scheduled commands




When running multiple servers behind a load balancer, scheduled commands would run on each server attached to your load balancer by default, which is not optimal. Not only would running the same command multiple times be a waste of processing power, but could also cause data integrity issues depending on what that command does


Laravel has a built-in way to handle this scenario so that your scheduled commands only run on a single server by chaining a onOneServer() method.
$schedule->command('report:generate')
->daily()
->onOneServer();



Using this method does require the use of a centralized caching server, so Step 2 is critical to making this work.


6. Deployment




When it comes to deploying your application, you now have so many options and things to consider.


We can still deploy our applications using our previous approach, but now we have to make sure we remember to click the deploy button on both servers. If we forget, we would have our servers running different versions of the application, which could cause huge issues.


With multiple servers, it’s probably time to level up the deployment strategy. There are some very good deployment tools and services out there, like Laravel Envoyer or PHP Deployer. These types of tools and services allow you to automate the deployment process across multiple servers, so you can remove human error from the equation.


If we want to go one level deeper in our deployment process, since we now have 2 app servers, one of the great benefits is that we can temporarily remove one of the servers from the load balancer, and that server will stop receiving requests. This allows us to have zero downtime deployment, where we remove the first server from the load balancer, deploy the new code, put it back into the load balancer, remove the second one and do the same process again. Once server 2 is finished, both servers will have the new code and will be attached to the load balancer. To achieve this, we would use tools like AWS CodeDeploy, but the setup is more complex than our previous options.


Deployment is a very important process of our applications, so if we can automate the deployment using Github Actions or any CI/CD services out there, we are greatly improving the process. Making the deployment process simple and where anyone can trigger a deployment really shows the maturity of the development team and the application.





7. Network & security




One additional benefit we have with the use of a load balancer is that our servers are not the entrypoint of our websites anymore. This means we can only have our servers be internally accessible and/or restricted by specific IPs (our IPs, Load Balancer IPs, etc). This greatly improves the security of our servers since they are not directly accessible. The same can (and should) be done for our database and cache clusters.


To achieve this, we are going to only allow traffic to port 22 from our own IPs (so we can SSH into the server) and we are going to only allow traffic to port 80 from the load balancer, so it can send requests to the server. The same rules apply for our database and cache clusters.


Final thoughts




There are a lot of things to consider when adding additional servers to your infrastructure. It adds more complexity to your infrastructure and workflows, but it also increases the reliability and scalability of your application as well as improves your overall security.


When considered from the beginning of the process, these recommendations are simple to implement and can have a large impact on improving your app.

CUDA Compute SM Throughput improvement for multiple loops

I'm interested in exploring different approaches to enhance the Compute (SM) Throughput of a CUDA code. It would be great to discuss with individuals having a good understanding of CUDA optimizations. To ensure a fruitful exchange and better comprehension, I kindly request that you also share code or algorithm snippets. If you are not familiar with CUDA optimizations, please feel free to disregard this request. Thank you!


First, let me describe the serial code. In the C code provided below, within both the first and second loops, we calculate 655 by 655 independent determinants. We then utilize weighted contributions to perform a summation over the second loop. The determinants are computed using LU decomposition. Ultimately, the objective is to compute the weighted contributions of these determinants.
I want to know which parallelization implementation would be better. That is, if there are multiple for loops, which loop should I consider for block and thread computation for time efficiency?


I have provided the details of these loops in the code below.
read_index(ind, ind_u, ind_d); // generates index for qc, det_store used later
int U=6;

for (it = 1; it < 64; it++) { // first loop, can be serial run
double sum1 = 0.0;
double sum2 = 0.0;

for (ii = 0; ii < 24*24*24; ii++) { // second loop, can be made parallel in blocks; values 24^3, 32^3, 48^3, 96^3}

read_qc(qc); // generates 4D qc array, different with each ii; size 3 * 3 * 4 * 4

int al[U], a[U], ap[U], alp[U]; // U=6
double _Complex A[U][U],AL[U][U],AU[U][U];
double _Complex det_store[655][655];

// every 655*655 has a A[6][6]
// det store [655][655]

int i,j,k,l;
for (i = 0; i < 655; i++) { //idx parallelize no dependency on above

for (k = 0; k < U; k++) { // al[k=U=6][i=655]
al[k] = ind[i][k]; //
a[k] = ind[i][k + U];
}

for (j = 0; j < 655; j++) { //jdx

for (k = 0; k < U; k++) {
alp[k] = ind[j][k];
ap[k] = ind[j][k + U];
}

for (k = 0; k < U; k++) {
for (l = 0; l < U; l++) {
A[k][l] = qc[a[k]][al[k]][ap[l]][alp[l]]; //Assigning the matrix element
}
}

Calculating the determinant using LU decomposition and storing them
LU_Decomposition(A, AL, AU);
det_store[i][j] = calculate_determinant(AU);
}
}

double _Complex temp;
//Uses above compute det
//
for (i = 0; i < 2716; i++) { //
for (j = 0; j < 2716; j++) { //
temp = weight[i]
* weight[j]
* det_store[ind_u[i]][ind_u[j]]
* det_store[ind_d[i]][ind_d[j]]; //combining the stored determinants using info from comb_he4.txt files
sum1 = sum1 + creal(temp);
sum2 = sum2 + cimag(temp);
}
}

}
printf("%d\t%.16E\t%.16E\n", it, sum1, sum2);
}



I am exploring various ideas and code snippets for an efficient implementation with minimal time stamp. If you can suggest improvements to LU_Decomposition functions with some CUDA libraries, that would also be helpful. Here is the LU_Decomposition function
void LU_Decomposition(double _Complex A[U][U], double _Complex L[U][U], double _Complex Up[U][U]) {
for (int i = 0; i < U; i++) {
// Upper Triangular Matrix
for (int k = i; k < U; k++) {
double _Complex sum = 0;
for (int j = 0; j < i; j++) {
sum += (L[i][j] * Up[j][k]);
}
Up[i][k] = A[i][k] - sum;
}

// Lower Triangular Matrix
for (int k = i; k < U; k++) {
if (i == k) {
L[i][i] = 1; // The diagonal elements of L are 1
} else {
double _Complex sum = 0;
for (int j = 0; j < i; j++) {
sum += (L[k][j] * Up[j][i]);
}
L[k][i] = (A[k][i] - sum) / Up[i][i];
}
}
}
}



I have parallelized the code mentioned above using CUDA by implementing a global kernel called gpu_sum. This kernel stores the reduced sum values for each iteration of the second loop, as described in the preceding C code. Below is the CUDA kernel
__global__ void gpu_sum(cuDoubleComplex *d_tqprop,
cuDoubleComplex *d_sum_nxyz,
int *d_deg_ind_up, int *d_deg_ind_down, float *d_deg_ind_weight,
int *d_ind, cuDoubleComplex *d_xdet){

int tid = threadIdx.x;
// int bid = blockIdx.x;
int gid = blockIdx.x;// * blockDim.x + threadIdx.x;

x3 = make_cuDoubleComplex(0.0,0.0);
temp_sum = make_cuDoubleComplex(0.0,0.0);
temp_sumA = make_cuDoubleComplex(0.0,0.0);

int start = 0;

}
}

WRN This kernel grid is too small to fill the available resources on this device, resulting in only 0.1 full
waves across all SMs. Look at Launch Statistics for more details.



My grid consists of 64 blocks, with each block containing 64 threads. However, when I increase the grid size, both the compute streaming multiprocessor (SM) throughput decreases and the time taken increases.

Is there a way to use awk to count the number of rows between 2 flags and input that number into a specific field?

I have a set of data that consists of seismic wave travel times and their corresponding information (i.e. source that produced the wave and the time for that wave arriving at each geophone along the spread). I am trying to format the data to fit my code in order to do some tomography using the data, but I'm still relatively new to awk. I am at a point where I need to now insert the number of receivers for each shot/source into the line of shot/source information, but its a variable amount each time. Is there a way to have awk count the number of rows and insert that into the proper field?


My data is formatted like the following.


Each line that documents a source/shot:


s 0.01 0 0 -1 0


Every other line that follows the source/shot information:
r 0.1 0 0 1.218 0.01
r 0.15 0 0 1.214 0.01
r 0.2 0 0 1.213 0.01




I can use the "s" as a flag for the shot lines, and I would like to count the number of "r" lines for each source/shot and insert that number into the corresponding "s" line.


The number of "r" lines for each "s" line varies greatly.


Given this sample input:
s 0.01 0 0 -1 0
r 0.1 0 0 1.218 0.01
r 0.15 0 0 1.214 0.01
r 0.2 0 0 1.213 0.01
s 1.01 0 0 -1 0
r 0.05 0 0 1.159 0.01
r 0.1 0 0 1.127 0.01
r 0.15 0 0 1.106 0.01
r 0.2 0 0 1.115 0.01
r 0.25 0 0 1.107 0.01



The expected output is:
s 0.01 0 3 -1 0
r 0.1 0 0 1.218 0.01
r 0.15 0 0 1.214 0.01
r 0.2 0 0 1.213 0.01
s 1.01 0 5 -1 0
r 0.05 0 0 1.159 0.01
r 0.1 0 0 1.127 0.01
r 0.15 0 0 1.106 0.01
r 0.2 0 0 1.115 0.01
r 0.25 0 0 1.107 0.01



Note the 3 as $4 in the first s line and the 5 as $4 in the second one.


The counted number of rows should be in the 4th column of each "s" line (asterisks here).


My experience with awk is limited to just rearranging/indexing columns, so I don't really know where to begin with this. I've tried googling help with awk, but it's very difficult to find answered awk questions that actually pertain to my specific situation (hence why I have decided to ask it myself).


I'm also new to using stackoverflow, so if I need to include more example data, please let me know. My data consists of approximately 4000 lines.


EDIT: The reason the desired result has slightly different data to the example of my data is because there are hundreds of lines for each "s" line and including that in the question seems excessive. I have cut out the majority of the data for ease of reading.

Disable Jupyter Notebook cell only for whole notebook run

I don't know if it is possible, but I have a Jupyter notebook where I'd like to disable some cells in case of a whole run.
That is, 'Run All' would jump over these cells and not trigger them, but they could still be used if ran alone (e.g. with Ctrl+Enter) without changing the code.


I know %%script false --no-raise-error does the trick, but you need to manually change a constant to re-enable the cells when you need them. Ideally, I'd not have to change anything in the code.

what do you do with model names, etc when the project is not in english?

I'm working on a project to manage specific legal orders in a country where english is not the language.

Although it's possible to translate some names in english, it becomes a little weird in some situations. For example a law requires to compile a form, it's weird if I translate the name of the form from the original language name into english, but it's also weird to have so much code in a language that is not english.

What do you do in these cases? submitted by /u/MobilePenor

cross-table query but filter doesn't works

I have two table,custom(click to show picture) gateway(click to show picture). custom.gateway_id's (pk) value is set as gateway.id
When i give a parameter(ex: 1 )The query is intended to retrieve data from CustomModelSerielPort where CustomModelSerielPort.gateway_id (ex:1)_matches Gateway.id (ex:1), and the data is only returned if Gateway.is_partner_ipc is equal to 1.
def list_serial_port(gateway_id: int, db: Session):
result = {"item_list": []}
serial_ports = (
db.query(CustomModelSerielPort.id, CustomModelSerielPort.path)
.join(Gateway, CustomModelSerielPort.gateway_id == Gateway.id)
.filter(Gateway.id == gateway_id)
.filter(Gateway.is_partner_ipc == 1)
.all()
)



If i give a parameter(ex: 3), i shouldn't get any data because Gateway.is_partner_ipc ==0,
However i still can get data, just like filter doesn't work, and if i change my condition to
.filter(Gateway.is_partner_ipc == 0)



I expect to get data when give a parameter(ex: 3) but no data when give a parameter(ex: 1 ), however both wont get any data, do anyone now what wrong with my code, thank a lot.

How to completely overwrite previous print with a new one? [duplicate]

I have to print a progress status, so update a print with a new one. I read many post that says you have to use "\r", so I tried this: print(string, end="\r", flush=True).


The problem is that when the previous printed string is bigger than the second one, some stuff of old print will reamins in the new print.


Here's the full code:
import time

long_string = "AAAAA"
short_string = "BB"
c = 0
while True:
if c % 2 == 0:
print(long_string, end="\r", flush=True)
else:
print(short_string, end="\r", flush=True)
c += 1
time.sleep(1)




I would expect that in the if it would print "AAAAA" and in the else it would print just "BB", but instead, in the else, it prints "BBAAA" because the "A" remains from previous print. Here's what I mean. I would like it would be just "BB" instead of "BBAAA".


I saw this post answer Python: How to print on same line, clearing previous text? so I tried to use os.sys.stdout.write('\033[K' + long_string + '\r') instead of print, but I still have the same problem and it also print a strange character


How can I completely delete previous clean and make a new one without traces of the old one?


Edit:


@Thierry Lathuille
Here's the full code with the second solution:
import time, os

long_string = "AAAAA"
short_string = "BB"
c = 0
while True:
if c % 2 == 0:
os.sys.stdout.write('\033[K' + long_string + '\r')
else:
os.sys.stdout.write('\033[K' + short_string + '\r')
c += 1
time.sleep(1)



It produces this output





I'm testing it in Windows 10 cmd.


Edit 2:
I said that the solution of "\r" didn't work and you closed my question and said that it has been answered in that thread. Are you kidding me right? Please open it again, that solution doesn't work, I already said it, that thread's answeres doesn't work to me and I explained why.

how would you approach baselining models and all of their relations?

I've been tasked with one of the more challenging things I've had to do in my 18 years+ career and as I try to wrap my head around the best approach to solve this, I thought I would ask here as well to see if I can gain anything from outside perspectives.

Hopefully this is allowed, I know it speaks of a specific problem, but it's also a general problem that others might have to deal with at some point so hoping that this thread could be of some use to others in the future.

In my project I have models who contain many nested relations, all of which themselves contain many nested relations. Including many pivot many-to-many relations. I've been tasked with making it possible to save a snapshot of the top level model, including all of its recursive nested relations. These snapshots, also called baselines or versions, can then be loaded at a later time. They can never be edited however, they are frozen in time.

My first approach was to create a new table for this and save the model and all of its recursive relations as json, with the idea that I could then later hydrate that json back into models and return them via my API. This is proving to be quite tricky as the process of re-hydrating my complex json into models and their relations is cumbersome and feels hacky. The idea with this approach is that I could have my snapshots contained and would not have to pollute my database with tons of "cloned" records.

My second approach would be to create duplicate copies of my models and all their relations whenever a snapshot is created. This feels like it would indeed work, but would result in potentially lots of extra rows, though that in itself shouldn't be much concern.

I was wondering if anyone can think of a better approach to my problem? Or if either of my two above approaches seem sound and valid?

Just thought I would pick some brains! Many thanks for any insight! submitted by /u/spar_x

VSCode IntelliSense autocomplete suddenly stopped working with node modules

I have my SteamUser object declared:
const SteamUser = require("steam-user");

It recognizes the logOn function:





But IntelliSense doesn't work. I tried restarting VSCode, entering command pallete and using the Developer: Reload Window command, but to no avail.


In a discord.js project IntelliSense also doesn't work:





I have run npm install:





Here is my package.json:

Conditionally Assert Throwing An Exception in Pest

---



Pest recently added the throwsUnless() method in Pest v2.24 to conditionally verify an exception if a given boolean expression evaluates to false.





This method is the counterpart to the throwIf() method, which conditionally verifies an exception if a given expression is true:
test('example 1', function () {
// Test that only throws an exception for the mysql driver...
})->throwsIf(DB::getDriverName() === 'mysql', Exception::class, 'MySQL is not supported.');

test('example 2', function () {
// Test that throws unless the db driver is mysql...
})->throwsUnless(DB::getDriverName() === 'mysql', SomeDBException::class);



For example, let's say that you have a PHP package that supports various PHP extensions for manipulating images. Your CI environment might support and test both gd and imagemagick; however, other environments might only support one or the other:
test('gd wrapper can create an image', function () {
$image = imagecreate(width: 200, height: 200);
imagecolorallocate($image, 255, 255, 255);
imagepng($image, '/tmp/new_image_gd.png');

expect(file_exists('/tmp/new_image_gd.png'))->toBeTrue();
})->throwsUnless(extension_loaded('gd'), \Error::class);

test('imagemagic wrapper can create an image', function () {
$image = new Imagick();
// ...

})->throwsUnless(extension_loaded('imagick'), \Error::class);



The throwsIf() and throwsUnless() methods also support callables if you prefer that style or have some custom logic that you want to use to determine if the test should throw an exception:
test('example test with callables', function () {
$image = new Imagick();
// ...
})->throwsUnless(fn () => class_exists(\Imagick::class), 'Class "Imagick" not found');

Write Single Page Applications using Laravel Splade

---



Laravel Splade, created by by Pascal Baljet, is a super easy way to build single-page applications (SPA) using Laravel Blade templates. Splade makes it easy to create modern, dynamic web applications that are a joy to use.





Splade provides useful Blade components that are enhanced with renderless Vue 3 components out of the box, such as the Component component. It provides that SPA-like feeling, but you can use Blade, sprinkled with interactive Vue components when required.


As you can see, in the default installation, the components fetch the page data via XHR and provide that SPA snappy feel without full page reloads.





You can use both Blade and Vue markup. Here's an example from Splade's component. Note the v-show directive and @click listener from Vue, and the Blade-specific component and variable usage {{ }}:

{{ $blog->full_content }}




{{ $blog->excerpt }}
Expand





If you need Custom Vue components, Splade has your back, and you can even utilize Server Side Rendering (SSR) to improve performance in your application.


If you also want to use Laravel Breeze or Laravel Jetstream, Splade provides starter kits for both. Splade also provides useful components out of the box you can use to get started quickly, with or without using the starter kits:



* Forms

* Links

* Events

* Flash

* Modals

* Table

* Teleport

* Toggle

* Transition

* And more!






You can get started with Splade quickly by checking out the homepage and accompanying documentation on splade.dev. You can also dive deeper and learn How Splade works under the hood.

Inertia and React or Vue

Hi just checking your thoughts on whether to learn React or Vue, I want to learn React as it may be better to find work and it has a larger ecosystem but my issue is is there are not a lot of tuts for Laravel and React with Inertia, do you have any recomendations for tuts? Also, what are your guys thoughts on Vue vs React with Laravel?

Here is the Reddit post I read that says they are finding it hard to get jobs with Vue.
