Best practices for importing and using files in react

I currently load a component when you go to the url /hsk1game. I have 6 urls hsk1game hsk2game etc. My single component loads the different files based on the url. I import my files as such:
import Hsk1Data from '../HskFiles/hsk1.json';
import Hsk2Data from '../HskFiles/hsk2.json';
import Hsk3Data from '../HskFiles/hsk3.json';
import Hsk4Data from '../HskFiles/hsk4.json';
import Hsk5Data from '../HskFiles/hsk5.json';
import Hsk6Data from '../HskFiles/hsk6.json';
I currently put the files into an array and pull out the correct file according to the current url. This works fine but I feel it might be expensive. I can put the data into a database and then only make a single request instead of importing them all. But I was wondering if there's a better way with files?
Thank you

So it depends on how much information is in those JSON files, people make a huge huff about performance when the reality is unless you are working with LOTS of data then its really negligible.
If your JSON files are massive, i'd recommend using the second method you described and returning that information via a request, because it won't be required by the bundler and so will reduce the amount of data that needs to be transferred when the page first loads.
If the JSON files are reasonably small, there is nothing wrong with just importing them.

How to import data from one svelte file to another

Sorry if I'm doing something wrong, I'm just starting with Svelte. I looked around on the web and couldn't find anything
I have a large hard coded data array made of objects that I want to keep in its own file while being able to access the data in app.svelte. I'm trying to keep my app.svelte as simple as possible. I tried export const data=[{data:"mydata"}] along with import {data} from "./data.svelte" but the export keyword means it expects the data to be sent over to data.svelte file, not the other way around. I really have no clue how to acheive this in Svelte. The data could also be json in a json file, as long as it is imported in my app.
Thank you for your help

.svelte files should be reserverd for components only, you can add your data in a regular javascript file instead
in data.js
export const data=[{data:"mydata"}]
in App.svelte
<script>
import { data } from './data.js'
</script>
This is possible with json files as well, but it will require an extra step as svelte does not by default understand json files. Depending on what bundler you use, you will have to add plugin, for Rollup this is https://www.npmjs.com/package/#rollup/plugin-json

Trying to export data to excel file without jquery

Im trying to export the data i have into an excel file without jquery. I've read you can use javascript but most example have jquery. The reason i don't want to use jquery is that the project is build with react.
I already have the data from the database, so i don't need to bring it again.
I want to take that data and make it into an excel file.
little bit of the code below.
<li className='col-md-3 col-height col-middle'>
<span>{fromTime}</span> //contains data
</li>
Some example use table, is it possible to export from
<div>
<li>
<span>
Would appreciate any tips, example or anything

The most common way to export data into excel would be to covert it into a csv (comma seperated values) file which can then be opened in excel.
There are plenty of tutorials on how to do this, there are many different ways with a simple google. In your case doing this in php will likely be best because your getting it from a database.

SheetJS seems perfect for this.
To export your table as an excel file use the code in this link(along with SheetJS)
Just plug in your table element's id into export_table_to_excel

Export object as Excel File in Angular js

I am working on an angular js where I need to export an array of javascript objects. My code already has the provision to export is as a csv. To export as a csv the way is quite simple. I am building an object where each item is separated by a comma and each row by a new line and then using filewriter to write the file. For excel I came across an option like Alasql. Is there anyway I can do it? Is it possible to format the object in such a way so that we can directly use filewriter to save the object as an excel file?
