Best way to preload route data before accessing the route.
Before rendering the page for a given route, I want to first get the necessary data synchronously. Ideally I'd like to get the data in the page component, but I'm not opposed to doing it in the router file. I've read and tried various approaches, but part of the challenge comes from the fact that there are multiple ways to build components, and the use of certain features varies. In my case, I use CompositionAPI and syntax to build single file components. The VueRouter documentation link talks about "get before navigation" where I have access to beforeRouteEnte

Catching Guzzle exceptions
I'm trying to catch exceptions in a set of tests running on an API I'm developing, and I'm using Guzzle to consume the API methods. I have wrapped the test in a try/catch block but it still throws an unhandled exception error. Adding an event listener as described in their documentation doesn't seem to do anything. I need to be able to retrieve responses with HTTP codes 500, 401, 400, in fact any response that is not 200, because if that doesn't work the system will set the most appropriate code based on the result of the call. Current code example foreach

Stream data from OpenAI's API using AJAX, PHP, and server-sent events
How can I use Server Sent Events (SSE) to stream data from the above API to a browser client using JavaScript and PHP? I've been working on this problem for hours and I can't seem to figure out what's going wrong. For reference, I tried adapting the solution here: StreamDATAFromopenaiGPT-3APIusingPHP The rest of my code is more or less the same as in the question above.

What are the performance numbers next to components in the Vue dev tools?
Does anyone have insights or resources for a certain feature in the Vue development tools? On the components pane, it shows my component, and then these little red and yellow squares, and what I'm assuming is the performance of the component. When I first load the app they don't appear, but for example I updated a text input component that validates its own formatting when the user enters a new value. This updates the Vuex storage and/or computed properties, but what baffles me is why the whole thing lights up like an angry Christmas tree. These performance data are displayed for unrelated components. When I check the Vuex history

How to roll back to PHP version 8.1: Docker phpdockerio/php:8.1-fpm build uses PHP version 8.2
I'm running my project on a PHP-FPM docker container (details of the config file below). When I build the container and try to run Composer, I get an error reporting that the PHP extension is missing. However, I think my build file covers these extensions (see docker/php-fpm/Dockerfile below). It turns out that the container was built with php8.2 as the default version. I've been able to change the symlink to set the default version back to php8.1 but this doesn't seem to be the right solution. Who can suggest more

What is event bubbling? In-depth analysis of event bubbling mechanism

Course Introduction：What is event bubbling? In-depth analysis of the event bubbling mechanism Event bubbling is an important concept in web development, which defines the way events are delivered on the page. When an event on an element is triggered, the event will be transmitted starting from the innermost element and passed outwards until it is passed to the outermost element. This delivery method is like bubbles bubbling in water, so it is called event bubbling. In this article, we will analyze the event bubbling mechanism in depth. The principle of event bubbling can be understood through a simple example. Suppose we have an H

Detailed explanation of JavaScript bubbling events: Understand the common types of bubbling events

Course Introduction：Detailed explanation of JavaScript bubbling events: To understand common bubbling event types, specific code examples are required 1. Introduction In web development, event processing is a very important part. Understanding the bubbling behavior of events and each event type is a prerequisite for efficient and elegant development. This article will introduce in detail the common bubbling event types in JavaScript and demonstrate their usage through specific code examples. 2. Definition of bubbling event A bubbling event refers to bubbling up from the event target element (such as a button) until it reaches the document root element.

Analysis of event bubbling mechanism: What is click event bubbling?

Course Introduction：What is click event bubbling? In-depth analysis of the event bubbling mechanism requires specific code examples. Event bubbling (Event Bubbling) means that in the DOM tree structure, when an element triggers an event, the event will be passed along the DOM tree from the child elements to the root element. This process is like bubbles bubbling, so it is called event bubbling. Event bubbling is a mechanism of the DOM event model, included in documents such as HTML, XML, and SVG. This mechanism allows event handlers registered on the parent element to receive

Course Introduction：As front-end technology continues to evolve, modern web applications are becoming more and more complex. To be able to handle the various events that end users may perform, developers must master some core concepts such as event capturing, bubbling, and delegation. In this article, we will focus on the concept of "event bubbling" and explore how to cancel event bubbling in uniapp. What is event bubbling? Before we dive into ways to cancel event bubbling, let’s first understand what event bubbling is. Event bubbling means that the event is triggered starting from the deepest element and then moving up to

What are the differences in the response mechanisms between bubbling and non-bubbly events?

Course Introduction：What is the difference between bubbling events and non-bubbling events? Specific code examples are required. Events play an important role in programming. They can be user interactive behaviors (such as clicks, drags, etc.), or browsers or web pages. internal behavior (such as loading completion, window size change, etc.). According to different event propagation methods, events can be divided into bubbling events and non-bubble events. Bubbling events (BubblingEvents) Bubbling events refer to events that start from the event target and propagate to the upper elements step by step until they are propagated to the document root.
