I emphatically disagree with BlueFish about observers being difficult to properly unit test. This is precisely the biggest point that distinguishes them from lifecycle callbacks: you can test observers in isolation, and doing so discourages you from falling into many of the state- and order-heavy design pitfalls BlueFish refers to (which again I think is more often true of lifecycle callbacks).

Some call them the lifecycle methods of elements which I think is an apt description.

In effect, the $ syntax we've seen above will actually setup a subscription to the store. And the subscription will be cancelled when the component is destroyed. If the store is subscribed by multiple components, the store will be disposed only when the last component unsubscribes (it will be reinitialized, if a new subscription is made). This is very handy to manage the lifecycle of disposable things in your code.

Third configurable block to run.
I like how they identify in the description which order things run in: 1st, 2nd, 3rd, and last.
Though, it would be more readable to have a list of them, in chronological order, rather than having them listed in alphabetical order.

Last configurable block to run. Called after frameworks initialize.

What I think is happening is that instantiating the component is immediately running the $: reactive code, which dispatches the event synchronously, before the parent component attaches the listener.
-
Thanks to that I have chance and time to properly initialise all the properties without reactive calls and I do not have to ignore these "initialising" events before proper initialisation.

Knowing exactly what happens in your application can mean the difference between feeling in full control or experiencing deep frustration. Personally, unknowns drive me crazy, which in turn often leads to all sorts of experiments and/or debug sessions.

The best place to initialize a FormValidation instance is inside the component's onMount event:
Why? Presumably because it needs access to a form element (
document.getElementById('loginForm')
)...

To fix our Svelte version you might think we could use beforeUpdate or afterUpdate, but these lifecycle functions are related to the DOM being updated, not to prop updates. We only want to rerun our fetching when the album prop is changed.

Svelte doesn't re-render, so you need to respond to component mount/dismount and prop changes separately as they are distinct concepts and never tied together, unlike in React.

Other lifecycle functions are onMount, onDestroy, etc. It is arguably less obvious that setContext is such a lifecycle method.

(Note that you're responsible for handling any race conditions that arise as a result of the component being destroyed before the promise resolves, though assigning state inside a destroyed component is harmless.)

With useEffect, you can handle lifecycle events directly inside function components. Namely, three of them: componentDidMount, componentDidUpdate, and componentWillUnmount. All with one function!

It's recommended to put the fetch in onMount rather than at the top level of the <script> because of server-side rendering (SSR). With the exception of onDestroy, lifecycle functions don't run during SSR, which means we can avoid fetching data that should be loaded lazily once the component has been mounted in the DOM.

Towards teaching as design: Exploring the interplay between full-lifecycle learning design tooling and Teacher Professional Development.
This article explores the theory of training teachers as learning designers to promote innovate and creativity. Included in the article are studies of designers with little teaching experience compared with those that are full-cycle teachers and the effect of TPD and LD upon training.

The Data Life Cycle: An Overview The data life cycle has eight components: Plan : description of the data that will be compiled, and how the data will be managed and made accessible throughout its lifetime Collect : observations are made either by hand or with sensors or other instruments and the data are placed a into digital form Assure : the quality of the data are assured through checks and inspections Describe : data are accurately and thoroughly described using the appropriate metadata standards Preserve : data are submitted to an appropriate long-term archive (i.e. data center ) Discover : potentially useful data are located and obtained, along with the relevant information about the data ( metadata ) Integrate : data from disparate sources are combined to form one homogeneous set of data that can be readily analyzed Analyze : data are analyzed
The lifecycle according to who? This 8-component description is from the point of view of only the people who obsessively think about this "problem".
Ask a researcher and I think you'll hear that lifecycle means something like:
collect -> analyze -> publish
or a more complex data management plan might be:
ask someone -> receive data in email -> analyze -> cite -> publish -> tenure
To most people lifecycle means "while I am using the data" and archiving means "my storage guy makes backups occasionally".
Asking people to be aware of the whole cycle outlined here is a non-starter, but I think there is another approach to achieve what we want... dramatic pause [to be continued]
What parts of this cycle should the individual be responsible for vs which parts are places where help is needed from the institution?
