            Using remove() to ensure element is not visible in DOM or by viewing source code
            Asked 2022-Apr-14 at 13:28

            I'm hoping you can help me solve a JS issue we're having.

            The Issue: I am removing an element when a class is present, and while this works to remove the element from the DOM via the inspector when I hit CTR-U and search for the element it is still searchable/visible.

            The blog article: https://www.leatherhoney.com/blogs/leather-care/diy-leather-car-interior-detailing-tips

            Background: The company that developed our website added (2) H1 headers to our blog articles. If the header is present, they are hiding one with CSS. This of course creates issues with multiple H1's on a page, even if it is visually hidden.

            The Fix: The fix is to remove the CSS property that is hiding the element and replace it with the remove() function. This would in theory remove the element entirely from the page (and from SEO crawlers) when the CSS class was present.

            The browser receives the HTML document, converts it into a DOM, and runs the JS which modifies the DOM.

            The source code is unchanged. It's the source code, not a reflection of the current state.

            You wouldn't want web browsers to be able to rewrite the code on your server: That would lead to your homepage being vandalised with new spam 30 times a second.

            If you want to change the HTML that the server sends to the browser (or sends to the search engine indexing bot) then you need to fix it on the server.

            Client-side render some components when using Angular Universal
            Asked 2022-Mar-14 at 23:59

            I am using Angular Universal for most of my website so that I can pre-render the content for SEO. It is meant to be a public facing site.

            I would like to be able to make certain components client-side rendered ONLY to avoid bundling content such as email addresses and social media links from being discoverable by web crawlers.

            I used the Angular Universal generated application to create my app. Currently, ALL my components are being rendered server-side. I couldn't find any specific clear example where someone used Angular in an elegant manner to achieve this specific goal. My intent is make my contact info and social media links components completely client-side rendered and added to the DOM at runtime to avoid bots and web crawlers from seeing it.

            How do others achieve this without doing something hacky?

            How to update a resource view count in REST API?
            Asked 2022-Mar-02 at 06:31

            I have an application containing videos. Each of the videos has a view count (represented by a property total_views) along with other properties such as its title, uploader, etc. A video view count should be incremented by 1 every time a video is requested/watched. The frontend of this application is a Next.js SPA and the backend is a Lumen/Laravel REST API.

            The current REST API backend solution returns the total_views as part of the video entity when the GET /videos/{id} endpoint is called on the API.

            I am not sure how to implement video count updates in the most REST generally accepted convention compliant way. I thought of updating the count on a request to GET /videos/{id} but I believe that this is not common REST standards/specification compliant (causing issues with caching, etc.) since the total_views property of the entity object in the response is being updated too. The second option I thought of is using another endpoint such as POST/PUT/PATCH /videos/{id}/views. However, I do not want to use a request body as the backend API should always increment by 1 only (and this way avoiding the client tampering with the view count). Another drawback of this option is that it introduces extra overhead as it requires sending another HTTP request in addition to the GET request for getting the video info.

            What are your suggestions?

            EDIT: Video view count here might also be seen as page view counts instead of actual video views/plays (Video resource views). Accurate view counting that filters out page views of crawlers, bots, or views where the visitor did not start the video are outside the scope of this question.

            The videos are hosted by external 3-rd party hosts and are only embedded via embed codes (iframe) in this application's video web pages.

            To do what you want correctly, you really want an 'increment' operation. This operation does not need a previous count, send the new total.

            The best fitting HTTP method is indeed PATCH. PATCH can do many things, and it's up to you to decide the meaning. For example, if your PATCH request looks like this, it's 100% correct:

            AWS Lambda@Edge Viewer Request fails with 'The body is not a string, is not an object, or exceeds the maximum size'
            Asked 2021-Nov-15 at 20:59

            I am trying to create a Lambda@Edge function to return Open Graph HTML for my Angular SPA application. I've installed it into the CloudFrond "Viewer Request" lifecycle. This lambda checks the user agent, and if it's the Facebook or Twitter crawler, it returns HTML (currently hard coded in the lambda for testing). If the request is from any other user-agent, the request is passed through to the origin. The pass-through logic is working properly, but if I try to intercept and return the Open Graph HTML for the crawlers, I get an error.

            In CloudWatch, the error reported by CloudFront is:

            ERROR Validation error: The Lambda function returned an invalid body, body should be of object type.

            In Postman (by faking the user-agent), I get a 502 with:

            The Lambda function result failed validation: The body is not a string, is not an object, or exceeds the maximum size.

            I'm pulling my hair out with this one. Any ideas? Here's my lambda.
