QUESTION
I am trying to save gas by optimize code. In a flash, however, I was wondered what is the best practice of copying from array to array in Solidity.
I present two option. One is copying by pointer (I guess) and the other is using for-loop.
TestOne.sol
...ANSWER
Answered 2022-Apr-10 at 21:23The best practice is copy array from memory to storage without looping over their items. However contract optimization in this example is tricky. The official documentation says as follow:
If you want the initial contract deployment to be cheaper and the later function executions to be more expensive, set it to
--optimize-runs=1
. If you expect many transactions and do not care for higher deployment cost and output size, set--optimize-runs
to a high number.
To illustrate above, consider following contracts:

QUESTION
When I usually write my code in remix solidity a blue dot usually appeared on the left side with code line's numbers as follows:
Kindly tell me what is it for?
Thanks for the help :) .
...ANSWER
Answered 2022-Mar-26 at 04:32That is called a breakpoint. Remix has a debugging feature that helps you debug transactions and analyze them line by line.
You can toggle a breakpoint by clicking on the space on the left side of the line number
QUESTION
While working on a project I noticed a weird behavior of the useLocation
hook that I can`t find an explanation to.
I have a button that when clicked it will redirect you to an EditOrder
page and will pass a state with it:
ANSWER
Answered 2022-Mar-20 at 22:24React's useLocation is based on the history library, which uses the BrowserHistory
in web apps.
Some browsers, like Chrome, persist BrowserHistory
state between sessions, while others (like Firefox) do not.
This is likely why you're seeing this behavior locally but not in a Sandbox. It appears that CodeSandbox's browser clears history state on refresh. It's also why, if you copy the URL into another tab, the redirect works. BrowserHistory
is local to a single tab.
In short, this is intended behavior. Either you need to clear the history state manually or store your application state elsewhere (useContext
could be a good choice if you want to persist across pages but not across a refresh).

QUESTION
I am setting up a Storybook with RemixJS. I got the following error when trying to import a component
...ANSWER
Answered 2022-Mar-11 at 12:09Depending on the webpack version you are using to build your Storybook you need to add fs
, stream
and other Node core module used by Remix packages.
As a rule of thumb you can use the list from Webpack documentation on resolve.fallback
here.
If you are using Stroybook with Webpack 4 the config should look like :

QUESTION
I am wondering if there is a way to redirect a route or return a Response with a data and fetch it at another page with the loader function.
Basically I am trying to create a new object with a form and redirect to another page where I wanted to display a creation success message.
Here is an form page example:
I am trying to send the message in the Response body.
...ANSWER
Answered 2022-Mar-11 at 22:18It's a good use case for session flash message 😎
https://remix.run/docs/en/v1/api/remix#sessionflashkey-value
The documentation provides a good example, but the idea behind that is :
- Get your form data in Index's action
- Store the stringify data in a session cookie flash message
- Return a response, using redirect function (helper imported from remix, that make a Response redirect for you)
- In NewPage's loader, read the session cookie message and return it. Don't forget to commit your session, it'll delete this flash message for you
- Use useLoaderData hook in your component to get the loader's return data
QUESTION
I implemented a dynamic array in solidity for my own use. The following is my implementation. I can get the accurate gas cost of each function call by clicking the debug message in the console of remix. However, manually getting gas costs is tedious and I'm thinking if I can write another solidity script to get the gas cost of my function call. For example, I want to get the gas cost of consecutively calling push
API for 10000 times. The x-axis should be the number of API calls, and the y axis should be the cumulative gas cost up to i API calls. Is there any built-in function in solidity to help me do that?
ANSWER
Answered 2022-Mar-10 at 06:06You can use msg.gas
and store the value to a variable, when the contract is executed the gas amount will be stored.
