remix | Redesign experiments with the Maizzle Email Framework | Email library

The goal is to style a prop inside a function (if the prop exists).

More specifically, I basically pass an icon (from styled-icons) as a prop to it and it is supposed to add styling to that icon.

This works with warnings:

welcome to my first SO question. I am trying to make a call to Spotify's API from my Express backend, and I am unable to get the data returned properly. The API request is not the problem - the correct information gets returned, I just can't seem to retrieve that info.

Here is the route which calls the getOldTracks function that contains the API call.

I am testing my smart contract on remix. While testing Start Airdrop function is running successfully but as I approach getAirrop function I receive error :

transact to getAirdrop errored: VM error: revert. revert The transaction has been reverted to the initial state. Note: The called function should be payable if you send value and the value you send should be less than your current balance. Debug the transaction to get more information.

my smart contract code is :

I have this crowdfunding platform that was initially using SafeMath library. And since is deprecated I'm looking for a workaround to make it compile and I'm getting a compilation error with remix in line 131:

I had this piece of code compiling in Solidity 0.6.0 without errors(I'm using Remix). But suddenly SafeMath library got deprecated because it wasn't necessary to import it anymore and I don't know how to fix this line:

uint raiseUntil = now.add(durationInDays.mul(1 days));

where I calculate a future date using the ¨mul¨ function.

I let you all code below. It's the backend of a crowdfunding platform. The raisedUntil variable is the date where the deadline of the crowdfunding project ends.

I just installed Remix IDE, and I'm trying to follow a tutorial for writing smart contracts. The very first step says to click the Environments button in Remix. However, that button is missing from the start page. I only have File, Featured Plugins, and Resources. The only place I see any Environments is when I click the icon for Deploy and Run transactions, there is an Environment dropdown box. However this box is missing the one I need, which is the Solidity environment. This box only contains Javascipt VM, Injected Web3 and Web3 provider. How do I fix this install of Remix? Thanks

I am trying to interact with a smart contract I set up. Basically the goal is to set from an iOS App 5 Parameters projectTitle projectLocation projectStart projectEnd teamType

I want the user to set those parameters and write it on the ropsten testnetwork.

I also would like to get the contract information at a later point whenever the user feels for it.

my solidity code is working properly in remix and the contract is already deployed:

I recently created a BEP20 token on remix etherium. But instead of writing the whole code, I used import "https://github.com/OpenZeppelin/openzeppelin-contracts/blob/master/contracts/token/ERC20/ERC20.sol" and added some 5-6 lines of my own.

1. If by any means, the GitHub repo gets deleted or shifted, will it affect my token? Will it stop working or could there be a loss of coins? If yes, how can I prevent this?

2. Also, while approving my contract on bscscan.com, should I put the contract code with the import statement? Because then it would be only 10 lines. Or should I paste the code from openZeppelin.git + extra added lines?

I realize this is a very beginner question so please bear with me. I recently started my first project in Solidity having come from solely using Python. When working with Python I constantly injected print statements to check the output of my work and ensure all was going to plan.

I'm having immense difficulty replicating this same workflow with Solidity. Even on the IDE front, I used PyCharm with Python which has a run command and output window but I can't find anything comparable Solidity. I'm using Sublime Text but that seems to be good for just writing the actual code and I can't find a way to call functions/mappings etc to a window to check output.

Remix has more features than most, but I'd prefer a local development environment. I've been looking for a while now and feel like I'm looking all the wrong places and not sure why the answer is so difficult to find for what seems like a simple issue. Any insight would be amazing.

Thanks!
