--- tags: brew-js --- # Breaking changes ## Upgrading to 0.6.x (Preview changes) ### Pure app event Event emitted to `app` itself no longer emit to `<html>` element. ```typescript app.emit('event'); // this is treated as pure app event // only event handler registered as app.on('event', handler) // will receive pure app event ``` I the event is intended to associates with the document root element, explicitly specifies as: ```typescript app.emit('event', document.documentElement); ``` Event listener registered to `app` will still receive the event. ```typescript app.on('event', () => {}); // this still works ``` On the other hand, if you are listening pure app event with target set to, move the target: ```typescript // before app.on(document.documentElement, 'event', () => {}); // after app.on('event', () => {}); ``` ## Upgrading to 0.4.x ### Feature moved to HtmlRouter When using router with html template, change to `useHtmlRouter`. ### Loading and error scope `loading` variable no longer automatically set when asynchronous operation is registered to DOM using `notifyAsync`. Add `loading-scope` to `<html>` to enable it. ```htmlembedded! <html loading-scope set-class="{ loading: loading }"> ... </html> ``` ## Upgrading to 0.3.x Starting v0.3, extensions must be loaded by `brew.with` in order to use when using Webpack. ```typescript brew.with(Router)(app => { }); ```
