            You should not use async in useEffect. This is not supported.

            I am not sure why you can't use getProtectedAsse(...).then(res=> {}).

            I am trying to write a function that will handle getting data to and from a server. This function takes the url to contact and uses the token to authorize itself against the server. This function is quite long. I would therefore want every other page in my react app to call this function with the needed url and then let this function handle everything else. I therefore need each page to await this function but I get "Error: Invalid hook call" no matter what I try.

            Cypress for Components Tests React configuration problem absolute path
            Asked 2022-Mar-21 at 21:05

            the goal is to use Cypress for component testing and e2e testing mainly. Install and configure all Cypress correctly, configure Cypress in the 'cypress open' script to open E2E related tests and configure the 'cypress open-ct' script for component tests, all settings work very well.

            Problem

            The project is already ready and I have absolute folders configuration, when I import a component from '~/components' I am accessing 'src/components', I am not able to make the proper settings to be able to access the absolute folders because when I run the cypress open script -ct doesn't seem to run 'file:preprocessor', where you need to run it to run the webpack where you have the absolute folder settings. I tried several alternatives and this was the one that worked the best because when I run the 'cypress open' script cypress executes 'file:preprocessor' it applies the webpack settings and if I try to import a component using '~/component/InputDate' it works , however 'cypress open' is for E2E tests, I can't run unit tests through this script.
            I can be wrong about the cypress open script not running component tests correctly but I'm looking for a solution to the big problem that is these absolute folders.

            Attempts

            I tried the tsconfig.json files configuration solution but I couldn't make it work because I use it in the jsconfig.json project, I tried to use tsconfig.json I used the 'tsconfig-paths' package and got no result.

            Verify JWT Token in angular
            Asked 2022-Mar-09 at 08:37

            My application backend runs on Django Rest Framework and and frontend on Angular.

            I'm already using JWT for authentication and that works fine.

            My requirement is to call a specific API (Not authentication related), which gets me some details in plain text. I don't want it in plain text, So I was thinking I would create a JWT Token and send it in response and decode it in frontend using the secret key.

            I achieved the decoding part using jwt-decode without the secret. My concern is, if an attacker intercepts my response and modifies the token, How do I tackle that situation?

            This is how I decoded the token in angular

            I don't want it in plain text, So I was thinking I would create a JWT Token and send it in response and decode it in frontend using the secret key.

            A JWT token is usually plain-text. There are two types of JWTs - JWS (signed JWTs) and JWE (encrypted JWTs). The latter has the content encrypted, so no one can read it unless they have the key for decryption. Encryption is hard to configure and manage, though, so JWEs are not used very often. You need a really strong reason to be using JWEs. Signed JWTs (JWS) are more common. In fact, when people use the term JWT, they usually mean JWS. A signed JWT is integrity-protected. Using the signature you can verify that the JWT hasn't been changed by an attacker, but they are plain-text. Anyone can read the content of the JWT, they just can't modify it.

            Also remember that an Angular app has all of its code available to users, which means it can't hold any secrets. If you put a secret in your Angular app, then anyone will be able to read that secret and use it to decrypt your JWEs, or forge new JWSs, if you're using symmetric signing (e.g. the HS256 algorithm).

            I achieved the decoding part using jwt-decode without the secret. My concern is, if an attacker intercepts my response and modifies the token, How do I tackle that situation?

            If you're concerned about a Man-in-the-middle attack, so that someone will modify the response from your server, then all you need is an HTTPS connection. If you connect to your API using HTTPS, then you're sure that no one modified the response, nor read it.

            If you're concerned that your response will get modified after HTTPS is terminated (e.g. a malicious code running in the browser), then you can use JWS to ensure the integrity of the response. You just have to remember to use asymmetric signing, so that the Angular app only keeps the public key.

            I don't know which library for JWTs are you using in Angular, but I think all of them are capable of verifying signatures, so that shouldn't be a problem.

            ANSWER

            Answered 2022-Jan-26 at 09:46

            jsonwebtoken is a Node.js module, your previous use of it in a react application relied upon a polyfill of the Node.js std modules. This most likely a) relied on slow js cryptography that isn't maintained anymore and lacks feature parity with Node's crypto and b) increased your js bundle size considerably. Updating react likely meant updating webpack which no longer defaults to using the questionable crypto polyfill.

            It is better to rely on modules made for either browsers or "universal", you can discover such modules amongst the ones listed on jwt.io under "JavaScript". Out of the ones listed there, jose uses purely available Web APIs.

            Vue app with Node backend doesn't render anything except the home page on Windows localhost, works in production and MacOS localhost
            Asked 2021-Dec-14 at 19:01

            The app has been running successfully in production for a year, and works perfectly on MacOS localhost. Recently needed to set up the app to run on Windows 10 localhost, and after resolving all the errors, now the app boots up, requests seem to get through, however, only the '/' page actually renders, all the other routes don't render and stay at a blank page.

            What could be a reason?

            During initial setup, I ran into an issue with windows-build-tools and a missing Python, which I ended up eventually resolving by installing everything through Chocolatey. Could this be related?

            Node version on Windows is newer than one specified in project, could this cause this?

            I'm happy to provide more details and perform any experiments any of you recommend or suggest. My own guess is that it is either something related to setup on Windows or some issue with the packages on Windows.

            Node version could be a problem. That windows-build-tools is required for the installation indicates there's binary dependency that is potentially incompatible with current Node version. Binary NPM dependencies usually provide a subset of precompiled binaries for a specific package version, where a combination of platform and Node.js version that can be considered safe or supported. For any other combination, binary package needs to be compiled for current platform with build tools. This doesn't always mean that the package is incompatible but this is common.

            For example, node-sass (doesn't seem to be used here) has different versions that correspond to specific Node.js versions and provides precompiled binaries for a supported subset; for unsupported Node.js version it falls back to compilation during installation process and most likely fails.

            It's unknown which dependency causes this problem in this case, this needs to be reviewed in npm/yarn logs.

            In order to avoid this situation, Node version could be matched with old one. Project dependencies need to be freshly installed because node_modules in use has been already tied to currently used Node version.

            If you keep handleLogout external to the useEffect hook it should be listed as a dependency as it is referenced within the hook's callback.

            If i put handleLogout to useEffect dependencies warning doesn't change.

            I doubt the warning is the same. At this point I would expect to you to see the warning change to something like "the dependency handleLogout is redeclared each render cycle, either move it into the useEffect hook or memoize with useCallback..." something to that effect.

            From here you've the 2 options.

            1. Move handleLogout into the useEffect so it is no longer an external dependency.
