Hello i'm having issue with uploading image to the cloud (Backblaze B2).

The problem is, when I use the example Thunder client to upload the file everything works fine and file is shown.

Now my problem is that when I upload with JS I don't know why it is corrupted or bugged. Like when I upload an image and download it, Windows File Manager says : file format not supported.

I decoded the file with base64 img decoder and it works fine and image is shown.

How to map through two arrays and send data as props to other component? I want to send data from price and gamedet as a prop to Wishlist Component.As I am new to react, suggest me if this code is not good or unclean too, thanks in advance.

This is the dumb way I send whole array to Wishlist component :

I'm following a tutorial in react that has you fetch from the yelp API a few things i don't understand that i hope someone would be able to clarify.

1: they aren't using async/ await, shouldn't this be common practice in 2021?

2: i don't understand the point/use of the headers in relation to Authorization:Bearer this is a more secure way of passing the key? cant i pass the apiKey in the url?

3: there is no catch or error handling in this, why is that/ where would that be inserted if i were to implement that?

4: this tutorial has me using something called 'https://cors-anywhere.herokuapp.com/' i don't really understand the use for this. it has to do with creating a secure way of retrieving the API from my understanding? but if i wanted to deploy this project on netlify would i just remove that and pass in the normal api url to fetch from? or how would i refactor for production deployment?

At the end of the day im really just looking for some guidance on how this can be improved.

I have a React dApp for a smart contract that I have made. In one of the routes of the application which I go by clicking a button named "All Cryptonauts" as seen in the screenshow below, I try to call all of the minted NFT's of my smart contract. I can successfully get them and map them all, but at first, nothing comes up.

However, after clicking the "All Cryptonauts" button again, all of the intended data gets shown.

Below, there are the codes of my page. I think my problem is with rendering, so I have made some research and someone said that they avoid to manually rerender and fix an identical issue with removing the key attributes from the HTML codes, but it didn't work for me and there were errors in the console when I removed the keys. I can't use this.setState here, too. Can anyone help me with the right way to do what I want please? Thank you!

I am a beginner both in Solidity and React, right now I am trying to create a front end application with React to interact with my smart contract. I have made a connect button in the first page of my application which takes the user to the next page after logging in with MetaMask.

In the second page, I load most of the information about the contract like prices, last minted NFT etc. Everything looks like they work in order except for setting my last minted NFT model.

Here's how my index.js looks, I don't use app.js, I use index.js instead of it. I have followed some tutorials about navigating through pages and followed it, the issue is not on this page, I'm just showing it for further information:

I'm using a 3rd party API https://www.metaweather.com and in my package.json i've added
"proxy": "https://www.metaweather.com",

My app.js is as follows:

I'm currently working on an app based on ionic 3.9.2. I'm trying to send a POST request to an API but I'm getting a 403 forbidden. orignally I had a CORS issue but I temporarily added https://cors-anywhere.herokuapp.com/ to the URL to bypass that. here is the function:

voucher-details.ts:

I'm trying to post some data into my db. In particular, I take the data entered in a form and I send a request to my backend (nodejs) at the address http://localhost:4000/insert. Anyway, when I tried to do that, I received many errors, so I modified the url in "https://cors-anywhere.herokuapp.com/http://localhost:4000/insert". But now, I receive this error: VM161:1 POST https://cors-anywhere.herokuapp.com/http://localhost:4000/insert 403 (Forbidden).

This app is very simple, so I'm not using any type of authentication; and I'm not requiring any type of authentication. How can I solve this problem? Here is my code: Thank you so much for your help!

I'm building an iTunes search project in react.js in which it fetch the music album data of the name entered in the input field. I'm using iTunes search api to get the data the data is in json format which contains 50 objects for each search.

The data which i get from the api is stored/set to the data state(i'm using hook to store the data object) in an array format.

Here i'm getting an data of each object by setData([json.results[0]])

but the problem is that map function is not able to iterate over the data state array.

I have tried all the things but the map function is not iterating over the data state object. And also it also not giving any error.

Can someone tell me why it is not working? Thanks in advance.

Here is the code.
