            Next failed to load SWC binary
            Asked 2022-Mar-22 at 05:46

            When trying to run the command using nextjs npm run dev shows error - failed to load SWC binary see more info here:

            I've tried uninstalling node and reinstalling it again with version 16.13 but without success, on the vercel page, but unsuccessful so far. Any tips?

            Also, I noticed it's a current issue on NextJS discussion page and it has to do with the new Rust-base compiler which is faster than Babel.

            This worked as suggeted by nextJS docs but it takes away Rust compiler and all its benefits... Here is what I did for those who eventually get stuck...

            ESlint - Error: Must use import to load ES Module
            Asked 2022-Mar-17 at 12:13

            I am currently setting up a boilerplate with React, Typescript, styled components, webpack etc. and I am getting an error when trying to run eslint:

            Error: Must use import to load ES Module

            Here is a more verbose version of the error:



            Answered 2022-Mar-15 at 16:08

            I think the problem is that you are trying to use the deprecated babel-eslint parser, last updated a year ago, which looks like it doesn't support ES6 modules. Updating to the latest parser seems to work, at least for simple linting.

            So, do this:

            • In package.json, update the line "babel-eslint": "^10.0.2", to "@babel/eslint-parser": "^7.5.4",. This works with the code above but it may be better to use the latest version, which at the time of writing is 7.16.3.
            • Run npm i from a terminal/command prompt in the folder
            • In .eslintrc, update the parser line "parser": "babel-eslint", to "parser": "@babel/eslint-parser",
            • In .eslintrc, add "requireConfigFile": false, to the parserOptions section (underneath "ecmaVersion": 8,) (I needed this or babel was looking for config files I don't have)
            • Run the command to lint a file

            Then, for me with just your two configuration files, the error goes away and I get appropriate linting errors.

            Switch' is not exported from 'react-router-dom'
            Asked 2022-Mar-01 at 09:07

            In package.json file react-router-dom dependencies added. App component wrapped by BrowswerRouter , but when I wrap route by switch it says the following error Switch' is not exported from 'react-router-dom'. I deleted the package.json.lock ,node modules, installed npm again and npm install @babel/core --save. Still not working. I successfully wasted 6 hour for this. Can you please help me to fix this? why it's not importing?




            Answered 2021-Nov-04 at 18:10
            Using Routes instead of Switch in react-router v6

            You are using react-router-dom version 6, which replaced Switch with the Routes component

            Why does Math.min() return -0 from [+0, 0, -0]
            Asked 2021-Dec-23 at 08:22

            I know (-0 === 0) comes out to be true. I am curious to know why -0 < 0 happens?

            When I run this code in stackoverflow execution context, it returns 0.



            Answered 2021-Dec-22 at 14:17

            This is a specialty of Math.min, as specified:

            1. For each element number of coerced, do

            a. If number is NaN, return NaN.

            b. If number is -0𝔽 and lowest is +0𝔽, set lowest to -0𝔽.

            c. If number < lowest, set lowest to number.

            1. Return lowest.

            Note that in most cases, +0 and -0 are treated equally, also in the ToString conversion, thus (-0).toString() evaluates to "0". That you can observe the difference in the browser console is an implementation detail of the browser.



            How can I trigger a :hover transition that includes three overlapping div elements (Venn diagram)
            Asked 2021-Oct-31 at 02:25

            My problem is that I have this Venn diagram consisting of three div elements and I want to scale them with :hover, so that when I hover over an intersection all the circles that meet in the intersection scale to my defined value. In the moment I only get one circle to scale at the time.



            Answered 2021-Oct-31 at 02:25

            You can achieve this, but you'll need a little JavaScript. Don't worry, it's nothing too complicated. What you can do is get the dimensions for each circle using the element.getBoundingClientRect() method, like so...



            ESLint broken: Rules with suggestions must set the `meta.hasSuggestions` property to `true`
            Asked 2021-Oct-15 at 01:18

            I am using VSCode, and when I add the line 'react-hooks/exhaustive-deps': 'warn' to my .eslintrc.js, I get the following in the ESLint output:



            Answered 2021-Oct-15 at 00:55

            ESLint 8.0.0 comes with a breaking change for rules that provide suggestions. There is nothing you can put into your .eslintrc.js to make it work if you use rules that haven't been updated to work after this change.

            What you can do:

            • Use ESLint 7 until the plugin is updated to work with ESLint 8.
            • In case of eslint-plugin-react-hooks, the offending rule has already been updated (check this line on GitHub), it's just that there hasn't been a stable release of the package since. However there have been daily alpha releases, at the time of writing the latest version is 4.2.1-alpha-c3a19e5af-20211014. If you really need both ESLint 8 and this plugin, you can use an alpha version until the next stable version comes out.

            Parcel SemVer bug

            So, I've used Parcel multiple times before and I've never had an issue with it. This time it throws some stupid errors about SemVer versioning and I'm literally loosing my mind trying to find a solution which would fix this problem.

            I've started new project: installed npm w/ npm init (no additional options), then installed parcel npm install --save-dev parcel-bundler and then created my folder structure:

            This is a known problem in the newest version of Parcel.

            The solution of this problem was to revert back to version 1.12.3, or by updating to the version 2 of Parcel. You can do the first solution by:
