I'm using supabase database to store my data, here is one table:
myTable, then I try to use fetch method in JavaScript to get data back, the code are as follows:
const res = await fetch('-', {headers: {apikey: '-',authorization: 'Bearer -',}}); fieldVal = await res.json();
(I have omitted the link)
Then I got the data back, but the order of the data confused me,
data
So, why the data of id equals 5 is the last data? Shouldn't be after the data of id equals 4?
This is my first time to use supabase, and I have scanned the docs and API, but it's a lot of other stuffs, I can't precisely locate the information I need.
You can order your query using supabase-js: https://supabase.com/docs/reference/javascript/order
const { data, error } = await supabase
.from('countries')
.select('id', 'name')
.order('id', { ascending: false })

I tried so many things and I researched lots of sites. But I can't find that how to parse this data without using modules. I am using node.js for this. My problem is I can't get the data from url to parse it. I hope my question is clear now. Thanks for answers.
const https = require("https");
https.get("https://coderbyte.com/api/challenges/json/rest-get-simple", (resp) => {
}
);
The documentation of the https.get function provides you with an example. Does that help you?
const https = require('https');
https.get("https://coderbyte.com/api/challenges/json/rest-get-simple", (res) => {
res.on('data', (d) => {
obj = JSON.parse(d.toString());
console.log("Hobbies",obj.hobbies);
});
}).on('error', (e) => {
console.error(e);
});
So within the get callback you need a listener on if some data was received.

I'm a bit new to Node.js and writing some GET REST APIs in Express.js. For one of my API, I need to pass 2 parameters to get the data from the database. I have achieved it using a single parameter but not more than 2. anyone help me, please?
Here my function
getByNPPTahunBulan(req,res){
console.log(req.param.tahun_bulan)
Iuran_Dapen.findAll({
where: {
tahun_bulan: req.params.tahun_bulan,
npp: req.param.npp
}
}).then((data) => {
return res.send(data);
}).catch((err) => {
res.status(500).send({
message: err.message || 'Some error occurred while retrieving data.',
});
})
},
and the url router.get('/iuranterakhir/:tahun_bulan/:npp', iuranDapen.getByNPPTahunBulan);
req.params contains a parameter object with its respective value with the following url /:id/:name
ej.
{
'id': 1,
'name': 'foo'
}
and you can do something like this:
const params = req.params;
and access as follows
params.id or params.name
the keys of the objects depends on the name of the parameters that you have given in the definition of your endpoint

If I work with tables (using react-tabele in my case), which store lot of pages of content.
When I first open first page and put that data in localStorage, then open second page and put that data to localStorage, then open third and store data in localStorage.
How should I handle it in reverse?
When I go back to second page, should I try to get data from localStorage() without sending request for those data?
Just bring it back from localStorage and render it?
If someone can give me example of using it in example similar like my case.
I saw mdn example, but they just wanted to show when you close tab you can inherit your old setup.
If I understand correctly, it's something related to caching your data in localStorage.
You can save timestamp together when you save the data to localStorage.
And when you arrive at that page again, you could check the timestamp and decide if you will send request or reuse the data in localStorage.
For example:
// when you save the data to localStorage
localStorage.setItem(KEY, JSON.stringify({
data: YOUR_DATA,
ts: Date.now()
}));
...
// when you read the data from localStorage
// here try/catch is used because JSON.parse will be error
// when the localStorage item is nothing or incorrect json string
try {
const { data, ts } = JSON.parse(localStorage.getItem(KEY));
if (Date.now() - +ts < SOME_SPECIFIC_TIMESTAMP) {
// use data
} else {
// send api
}
} catch (err) {
// send api
}
However it depends on why you save the data to localStorage.

Can anyone help me ?!
I won't like this style just I want to know how can i retrieve data and add it in new html pages in the same style in all courses .
You can retrieve data from a firebase realtime database like so:
// Import Admin SDK
var admin = require("firebase-admin");
// Get a database reference to our posts
var db = admin.database();
var ref = db.ref("path/of/your/information");
// Attach an asynchronous callback to read the data at our posts reference
ref.on("value", function(snapshot) {
console.log(snapshot.val());
}, function (errorObject) {
console.log("The read failed: " + errorObject.code);
});
See Official Documentation here
Note: requires Node.js / npm

I'm new to APIs and am trying to figure out how to make a Zillow call with JavaScript, specifically the "getsearchresults".
Thanks
You'll need to use Javascript on the server-side using Node. It won't be possible to call the API on the front-end with Javascript. See this answer.
For using Node to call the Zillow API, check out the node-zillow package. Here's an example of how to use it with the GetSearchResults API call:
const Zillow = require("node-zillow")
const zillow = new Zillow('your key here')
const parameters = {
address: "2114 Bigelow Ave",
citystatezip: "Seattle, WA",
rentzestimate: false
}
zillow.get('GetSearchResults', parameters)
.then(results => {
console.log(results)
return results
})
Make sure you signup for ZWSID here: https://www.zillow.com/webservice/Registration.htm. You'll use this unique id when making the request to the API. It'll look something like this: X2-Ijdjkxlujnkd_jske2. Keep it secret, keep it safe!
