Change Detection

Sling supports two change detection strategies: automatic and manual. The default mode is automatic.

Strategy	Description
s.CHANGE_STRATEGY_AUTOMATIC	Automatically update components after browser events and requests. This is the default setting.
s.CHANGE_STRATEGY_MANUAL	Manually update components after browser events and requests.

Automatic change detection performs updates upon the following:

• All browser events (click, mouseover, keyup, etc.)
• setTimeout and setInterval
• XMLHttpRequest and Fetch API requests

Automatic change detection does not perform updates upon the following:

• Websocket events
• IndexedDB callbacks

For versions of setTimeout and setInterval that do not trigger automatic change detection, use the following:

• s.DETACHED_SET_TIMEOUT()
• s.DETACHED_SET_INTERVAL()

For example:

s.DETACHED_SET_TIMEOUT(() => {
    console.log('Hello, world!');
}, 0);
