            Uncaught ReferenceError: process is not defined / Line 0: Parsing error
            Asked 2022-Mar-12 at 16:14

            For a simple project, when running npm install and npm start, my default web browser1 opens, and I hit F12 to see two types of error messages in the console.

            As you can see, the error messages are:

            • Uncaught ReferenceError: process is not defined, and
            • Line 0: Parsing error: ImportDeclaration should appear when the mode is ES6 and in the module context.

            What should I do to rectify these errors?

            I believe these errors are related to ReactJS, which under the hood uses Webpack.

            I have seen these errors elsewhere, sometimes with a reference to version issues for ReactJS and/or Webpack. For more examples, see the list of references below. Some of those links (questions) might be related to the issues here, but I am not sure.

            I provide my .eslintrc.json and package.json files below. But since they will hardly be sufficient to reproduce the error, here is a link to a zip file containing all the necessary project files. 2

            Update all npm packages to their latest versions

            Consider updating all npm packages to their latest versions.
            The purpose is to decrease the risk of getting version conflicts.

            I haven't really grasped the meaning of your component, but I would say that initializing your "radioList" variable to 0 should be sufficient.

            Also, it would be better to go by the id of your ColorValueObjInterface. it would give, in your .ts



            One of my iframe is not working/loading ios ionic
            Asked 2022-Feb-22 at 10:47

            One of my iframe is not working/loading in IOS only (mobile and emulator) while it is working fine android/chrome/safari. It happens to only one iFrame, while a second is working (in IOS).

            I have the following message error: webPageProxy::didFailProvisionalLoadForFrame: frameId = 26, domain = nsurlErrorDomain, code: -999.

            I have implemented both answer from stackoverflow: Ionic iframe loading not fully working on iOS iframe is not working in iOS (ionic framework)

            Plus i have sanitize the url of the iFrame. Nothing seems to work, the iFrame is white.

            The url I am passing (in case it is working:) The url I am passing (in case it is not working

            These two urls are from action POST form, with an iFrame as a target.

            Do you have any idea what to do ? Would it be possible that the host has badly set its website ?

            Would it be possible that it comes from the fact that the iFrame has this error: Indicate whether to send a cookie in a cross-site request by specifying its SameSite attribute ?

            We had the following error: “Refused to load because it does not appear in the frame-ancestors directive of the Content Security Policy.”

            The CPS, from my understanding is what securized your website of being embedded by another one.

            And indeed the third party request header CSP frame-ancestors is set to:



            Ionic - Routerlink not triggering Lifecycle events
            Asked 2021-Dec-02 at 21:41

            I'm struggling with Ionic's lifecycle events used with RouterLink.

            I have my app data in a JSON file that renders each item using the url paramenters when the page is loaded. I need buttons to go to the next or previous item and refresh the page content, ie:

            • I'm on Item 1 (/lecture/item1) => click next => routerLink(/lecture/item2)
            • I'm on Item 1 (/lecture/item1) => click prev => routerLink(/lecture/item0) That means that each time i move to a page i need to get the params from the url (/lecture/:param) and update the page data. The problem i'm facing is that RouterLink isn't triggering any Page Leaving lifecycle, so my states doesn't change, also, i can't clean the states (i can do it through an href param, but the whole app is refreshed). I found similar threads on this, but some of them are outdated/still opened: Routerlink bug github.

            Is there any way/workaround to reload the component and update the states passing different parameters?

            I already tried using useHistory hook, history.replace (Source), and routerDirection="back" but none of them are triggering ion page leaving hooks. I also tried replacing IonRouterOutlet with Switch but this means not having some important ionic features.

            Thank you in advance!!

            Here is an extract of code for reference:

            Answered 2021-Dec-02 at 21:41

            Normally a useEffect with dependency on the route match param is sufficient for issuing side-effects like refetching relevant data.

            The ionic useIonViewWillEnter and useIonViewDidEnter hooks described here are basically mounting lifecycle hooks, and don't seem like they'd trigger if you're already on a view and only changing URL path parameters. Move the logic to a useEffect hook which is called when component mounts and when any of its specified dependencies update.




            Return object from function in a service in ionic (ionic picker)
            Asked 2021-Nov-30 at 19:13

            In my app, I would like to have a different picker, with two or three columns, so I made 2 different functions to simplify the code. Now I'd like to return my object with my result when the Validate button is pressed. I think I need to deal with Promise, but I am not so familiar with it and I think I am doing something wrong.

            Here is my function inside my service :



            Answered 2021-Nov-30 at 19:13

            You can use Promises with async like so. I can't execute your code since I don't have the complete Class, but this should give you the idea.

            Note: I didn't modify the validator method, but you can use the approach I outlined below to do validation work in the handler and resolve or throw an error accordingly.

            First thing to do is return a Promise in the pickerTwoColumns:



            Ionic routing breaks when navigating to url twice
            Asked 2021-Mar-30 at 11:37

            When navigating through a page stack i've discovered that when i visit the same page twice the does not behave as expected. Here is a graphic of the issue.

            It seems that Ionic does not navigate back from the last data of Page 1 but rather of the first occurrence (red arrow). I've found a similar Github issue 16516 which should be fixed but it doesn't work for me.

            Has anyone encountered this or can provide a fix/workaround?

            My Versions



            Answered 2021-Mar-30 at 10:10

            I've come across the exact same issue. I think the issue is based on the page url and not on the page component itself. If you navigate to an url that already exists in the navigation stack history, Ionic will redirect you to that existing page and will also remove all pages in between.

            The workaround I'm using for now is to add a timestamp to each page's url that is likely to be added several times in the navigation stack. This will make sure that a new instance of a page component will be created and pushed into the stack instead of reusing an old one.




            Destructure React component into "building blocks"
            Asked 2021-Feb-14 at 11:19

            I am using IonSlides in my app but due to a bug with them, dynamically adding slides can prove difficult. Because IonSlides is built upon SwiperJS, it has some methods to add and remove slides. The downside to those is that they take a string with HTML in it. In my case, I need to be able to pass in JSX elements so that I can use event listeners on them. Originally, this was my code:



            Answered 2021-Feb-14 at 11:19

            For whatever reason that someone needs this, I found you can do el.type(el.props) where el is a JSX element. This creates an instance of the element so under children instead of seeing the props, you can see the actual child components of the component.



            From Ionic/Angular is it possible to get a reference to the underlying Stencil Web Component?
            Asked 2020-Dec-07 at 19:33

            I have an Ionic 6/Angular 10 app using an ion-content content area.

            The problem I am running into is that the angular ngAfterViewInit() callback is fired before the DOM is completely rendered so any size queries I do during that callback end up being inaccurate. I have been struggling to find some callback to let me know when the render process has completed so that I can query elements for their final sizes, to no avail.

            I came across this github issue discussion:

            It seems to imply that one can get a reference to the underlying Stencil based Web Component in order to hook callbacks at that level and get the callback I'm looking for, namely componentDidRender().

            However, following the example in the thread does not provide any reference to the methods mentioned in the Stencil documentation.

            Is it possible to get a reference to the underlying Ionic Web Component? If so, how?




            Answered 2020-Dec-07 at 19:33

            I assume what you're looking for is DOM element referencing, which is done via ViewChild in Angular.




            Access-Control-Allow-Origin not working with ionic 5 app
            Asked 2020-Aug-10 at 19:27

            I am following a tutorial to send and receive data from my server in an Ionic application and I am having trouble doing that because of CORS. I am very familiar with the CORS issue and have used the "Access-Control-Allow-Origin" solution often when connecting my Javascript Ajax code to the PHP backend on my server. However, nothing seems to work for Ionic. I've seen several questions/answers here on SO, as well as read some blogs, and they all say this should work but it doesn't.

            I have complete control over my endpoint and have created a PHP file there that looks like this:



            Answered 2020-Aug-10 at 19:27

            I found the problem and the fix. As expected it was in the Ionic App's code. But it was not quite what I expected. Hopefully, this may be useful to someone in the same predicament. The problem was this line:



            Get selected tab to switch icons Ionic 5
            Asked 2020-Jul-16 at 15:13

            I'm trying to change my tab icons from filled to outline when someone selects it (filled when selected, outline when not selected).

            On the Ionic 5 Tabs Doc there's a getSelected() method but no examples on how to use this.

            My idea was to use ionTabsDidChange to detect when someone clicked a tab, then use getSelected() and set the icon from 'home' to 'home-outline'.




            Answered 2020-Jul-16 at 15:13

            You are heading the right direction, there are still few missing points. In the Ionic doc you are reading the "events" are not directly accessible in the page without binding them to the component itself and in order to use ViewChild you also need to give the component an id:
