I am trying to generate a session ID and then send that session ID to the front end of my application in the header (I know I should use the body to do this but my prof wants us to use header so we know how to use it).
The fetch response that I get has head but its value is {}, but I'm also getting a 200 'OK' so I know it is at least connected to the front end correctly.
My backend code is this:
router.get('/sid', function (req, res) {
res.setHeader('X-sid', getSid());
res.send();
});
My frontend code is this:
function sessionId() {
fetch('/wordgame/api/v1/sid').then(x => {
console.log(x);
});

I have this retarded amount of product in a collection on Shopify (over 50k products) and I would need to delete them all, is there a way I can automate that? All I can find on the internet is to use the "bulk edit tool" which is the most useless thing I've ever seen as it can only grab 50 products at a time.
I've tried automating a script to update the rows with the CSV export file, but it takes over 6 hours for 20K products to import. Plus, since there are hashtags in the title and handle, it apparently doesn't overwrite the products for some reason. So I just can't use the archive anymore...
Has anyone ran into this issue and found a solution?
Thank you!
When it comes to this kinds of tasks I usually write myself a quick dev console script that will do the job for me instead of relying on an app.
Here is a script that you can use in the dev console of your shopify admin page (just copy /paste):
let productsArray = [];
// Recursive function that will grab all products from a collection
const requestCollection = (collectionId, url = `https://${window.location.host}/admin/api/2020-10/collections/${collectionId}/products.json?limit=250`) => {
fetch(url).then(async res => {
const link = res.headers.get('link');
const data = await res.json();
productsArray = [...productsArray, ...data.products];
if(link && link.match(/<([^\s]+)>;\srel="next"/)){
const nextLink = link.match(/<([^\s]+)>;\srel="next"/)[1];
requestCollection(collectionId, nextLink)
} else {
initDelete(productsArray)
}
})
}
// Get CSRF token or the request will require password
const getCSRFToken = () => fetch('/admin/settings/files',{
headers: {
"x-requested-with": "XMLHttpRequest",
"x-shopify-web": 1,
"x-xhr-referer": `https://${window.location.host}/admin/settings/files`
}
}).then(res => res.text()).then(res => {
const parser = new DOMParser();
const doc = parser.parseFromString(res, 'text/html');
return doc.querySelector('meta[name="csrf-token"]').getAttribute('content')
})
// The function that will start the deleting process
const initDelete = async (products) => {
const csrfToken = await getCSRFToken();
products.forEach(item => {
fetch(`https://${window.location.host}/admin/api/2020-10/products/${item.id}.json`, {
method: "delete",
credentials: 'include',
headers: {
"x-csrf-token": csrfToken,
"x-requested-with": "XMLHttpRequest",
"x-shopify-web": 1,
"x-xhr-referer": `https://${window.location.host}/admin/settings/files`
}
})
})
}
And you start it by using requestCollection(ADD_YOUR_COLLECTION_ID_HERE).
To clarify the script, there are 3 main functions:
requestCollection - this handles the product grabbing from the collection. It's a recursive function since we can't grab more than 250 products at the same time.
getCSRFToken - this grabs the CSRF token since most of the post/update/delete request requires it or they will fail (I grab it from the files page)
initDelete - this function start the delete process where we stack all the request one of the other without waiting, you may want to await each request, but even if you crash your browser I think it will be still faster to repeat the process rather then wait for each request to finish.
If you plan to use this script please TEST IT BEFORE USING IT. Create a collection with a few products and run against that, in case there are issues. I've tested it on my side and it's working but it's a code I wrote in 10 minutes after midnight, there can be issues there.
Have in mind that this script will delete ALL products in the collection you specify in the requestCollection(1231254125) method.
PS: All of this can be done using a Private App as well with the products scope set to read/write, using a back-end language of your choice. The main difference will be that you won't need the CSRF token and most of the headers that I set above. But I like quick solutions that doesn't require you to pull out the big guns.
Im having issues with delete request, my post, get are working fine.
What am I doing wrong?
removeUser(id) {
axios.delete('https://jsonplaceholder.typicode.com/users' + id)
.then(function(response) {
const user = response.data;
this.users.splice(id, user);
});
if response.status === 204, then delete is succeed.
for the client, here is an axios example, notice there is a ' after users
destroy() {
return request.delete('/api/users/' + id)
}
for the server, here is an Laravel example:
if( $article->delete() ) {
return response()->json(null, 204);
} else {
abort(409);
}
I can see only 1 problem on the code you provided.
You're trying to modify the Vue instance $data users object by executing this.users.splice(id, user);. But you're inside the callback function and this no longer represents the Vue instance.
To fix this & make the users object actually modify after the response comes you'll need to do it like this :
removeUser(id) {
let that = this;
axios.delete('https://jsonplaceholder.typicode.com/users' + id)
.then(function(response) {
const user = response.data;
that.users.splice(id, user);
});
Now , I don't have any code from the back-end so I'll just make some assumptions :
The route might not be well defined > if you're using NodeJS then you should check your routes , it should look like this :
router.route('/users:id').delete(async function(req,res,next){ /* ... */ });
You might have a route problem because / is missing before the user value
1 hint : Again , if you're using NodeJS , you could use this inside your .delete route :
res.status(200).json({ errorCode : null , errorMessage : null , users : [] });
To see if you're receiving it on front-end.
I think you do need to append the trailing '/' to the URL, that way the URL is properly formed, such as "https://jsonplaceholder.typicode.com/users/123" (rather than "users123" at the end).
Aside from that, the first parameter to Array.prototype.splice is the position where item removal should begin. The second (optional) parameter, deleteCount, is the number of items to remove. Beyond deleteCount, you can pass a collection of objects which are to be inserted after the start position and after items have been removed.
You just need to find the object in your this.users array and remove it. If you want to use Array.prototype.splice for that, then you can use Array.prototype.findIndex to find the index of the user in the array then remove it:
// Find the index of the item to remove
const indexOfUserToRemove = this.users.findIndex(u => u.id === id);
// Call splice to remove the item
this.users.splice(indexOfUserToRemove, 1);
My thing is a small project.
In main what it does is that the "server" will get a call from the link directly what will run some functions that will update the database and the data that has to be shown.
I will show what I mean:
function updateData(){
connection.query(`SELECT * FROM muzica WHERE melodie = "${updateList()}"`, function (error, rezultat, fields) {
if (error) {console.log('err la selectare')};
//express output
let data = {
melodie: rezultat[0].melodie,
likes: rezultat[0].likes
}
console.log(data.likes);
app.get('/like', (req,res) =>{
res.json(`${data.likes}`);
});
}
setInterval(()=>{
updateData();
}, 20000)
Uhh, how to explain it, I'm so bad at this...
So, in main, I'm new to back-end work, everything that I did was based on their Documentation as I learn way faster by my needs than some guides and so on.
So, when I or someone does my http://website/like it should show just data.likes, cause that is all that I need, don't count data.melodie (i will clean that later on) after I finish all the code.
Anyway, whenever I do website/like data.likes is not updating to the new database data.likes.
For example, data.likes before were 5, in a few minutes it can be 2 but whenever I call website/like show "5" than its new value 2.
Don't be hash on me, I'm new and I want to learn as much as I can, but I can't understand the above case, by my logic it should ALWAYS show what its in database when it refreshes each 10 seconds(I run this in localhost so I will not stress any online server).
But if there is any better way to check for databases update than "setInterval" please notice me.
It's hard to learn alone without a mentor or someone else to talk about this domain.
Thank you for your time!
Kind regards,

You have things a bit inside out. A request handler such as app.get('/like', ...) goes at the top level and you only ever call it once. What that statement does is register an event handler for any incoming requests with the /like path. When the server receives an incoming request for /like, it will then call the function for this route handler.
You then put inside that route handler the code that you want to run to generate the response and send the response back to the client.
app.get('/like', (req, res) => {
connection.query(`SELECT * FROM muzica WHERE melodie = "${updateList()}"`, function (error, rezultat, fields) {
if (error) {
console.log(error);
res.sendStatus(500);
} else {
//express output
let data = {
melodie: rezultat[0].melodie,
likes: rezultat[0].likes
}
res.json(data);
}
});
});
The endpoints need to be outside of any functions in express.
For example, if you look at the express "hello world" example here, you will see that they have a basic app that only has a single GET endpoint defined which is "/" so you would access it by running "localhost/" or "127.0.0.1/".
In your case, you want your endpoint to be "/like", so you must define something like:
const express = require('express')
const app = express()
const port = 3000
app.listen(port, () => console.log(`Example app listening at http://localhost:${port}`))
app.get('/like', (req, res) => {
// do database stuff and assign data variable
// res.json(data);
}
I have a data table in Vuetify that is populated via a REST get request, using a function "getData" that is called when the app is mounted. The <td>'s in the table have buttons that the user can hit to "lock" the period (the row/column intersection).
When they hit the button, they get a popup confirmation dialog. When they hit "OK", there is a save method called to write the current date back to the db via a REST PATCH request (see below).
My problem is, the grid is not updating with the results of the patch request. I have to manually refresh the page to see the result. What is the common pattern here? Should i pull down the data again via getData to refresh the table? Should i update the array that the data-table sits on directly?
getData method:
getData() {
var self = this;
return axios
.get("http://127.0.0.1:5000/api/estimatefinal/periods?dataset=capital")
.then(function(response) {
self.periods = response.data;
})
.catch(function(error) {
alert(error);
});
},
Save method:
save(item) {
var self = this;
axios
.patch("http://localhost:5000/api/estimatefinal/period/" + self.id, {
date: moment(self.selected_date, "YYYY-MM-DD").format(
"YYYY-MM-DDTH:m:s"
)
})
.then(function() {
this.getData(); // ????
})
.catch(function(error) {
alert(error)
});
this.getData(); // ????
this.close();
}
If your PATCH changes only one row in DB, means has visually effect on only one row on your v-data-table, then you can change the data locally when you get "success" response from back-end.
If, in other hand, your PATCH changes many other things in DB (also in v-data-table) your best option is probably to getData() after you get PATCH response.
Point is to keep that same "picture" of values in DB and on screen v-data-table.
I want to call LESS's darken() function on whatever the current color is (I don't have the current color in any variable). Is that possible?
as per seven-phases-max request; in your node backend let say express
var less = require('less'); //also the body parser, express, etc
....
from your page you make an asynchronous request with the actual color of your page, just grabbing it with js and making the request. then in express:
app.post('/whateveryourroute', function(req, res) {
var colorFromReq = req.body.color;
less.render('.class { color: darken(`colorFromReq`, 20%) }', function (e, css) {
res.header("Content-type", "text/css");
res.send(css);
});
});
Something like that would be, didnt test it, but is possible.
