+subtitle: Observing the life cycle of an element
+---
+
+Catalyst Controllers - like many other frameworks - have several "well known" method names which are called periodically through the life cycle of the element, and let you observe when an element changes in various ways. Here is a comprehensive list of all life-cycle callbacks. Each one is suffixed `Callback`, to denote that it will be called by the framework.
+
+### `connectedCallback()`
+
+The [`connectedCallback()` is part of Custom Elements][ce-callbacks], and gets fired as soon as your element is _appended_ to the DOM. This callback is a good time to initialize any variables, perhaps add some global event listeners, or start making any early network requests.
+
+JavaScript traditionally uses the `constructor()` callback to listen for class creation. While this still works for Custom Elements, it is best avoided as the element won't be in the DOM when `constructor()` is fired, limiting its utility.
+
+### `attributeChangedCallback()`
+
+The [`attributeChangedCallback()` is part of Custom Elements][ce-callbacks], and gets fired when _observed attributes_ are added, changed, or removed from your element. It required you set a `static observedAttributes` array on your class, the values of which will be any attributes that will be observed for mutations. This is given a set of arguments, the signature of your function should be:
+
+```typescript
+attributeChangedCallback(name: string, oldValue: string|null, newValue: string|null): void {}
+```
+
+### `disconnectedCallback()`
+
+The [`disconnectedCallback()` is part of Custom Elements][ce-callbacks], and gets fired as soon as your element is _removed_ from the DOM. Event listeners will automatically be cleaned up, and memory will be freed automatically from JavaScript, so you're unlikely to need this callback for much.
+
+### `adoptedCallback()`
+
+The [`adoptedCallback()` is part of Custom Elements][ce-callbacks], and gets called when your element moves from one `document` to another (such as an iframe). It's very unlikely to occur, you'll almost never need this.
