Despite the current health situation, resulting difficulties with travel and event restrictions, EmberConf 2020, March 16th-18th is around the corner and will definitely be on! As usual, you can enjoy inspiring talks about Ember, the web and open-source from community members from all around the world at EmberConf's first-ever all-virtual conference!
100% of the conference talks will be delivered remotely at the regularly scheduled time at emberconf.com - ready to watch together with your colleagues and Ember friends. Hangout with other conference attendees at #ember-conf on the Ember Discord to share your thoughts on your favorite presentations and do not miss out on your digital conference swag bag.
Last but not least, we would like to thank everyone involved in the setup of this amazing conference we all love; in particular, we would like to thank and also ask you to please extend a warm thank you to Leah Silber (@wifelette) who is making this year's awesome EmberConf possible against all odds. If you meet her virtually, be sure to send her a ❤️!
As reported by the CSSE blog, "the dashboard, first shared publicly on January 22, illustrates the location and number of confirmed COVID-19 cases, deaths and recoveries for all affected countries. It was developed to provide researchers, public health authorities and the general public with a user-friendly tool to track the outbreak as it unfolds. Further, all the data collected and displayed is made freely available, initially as google sheets, now in a GitHub repository, along with the feature layers of the dashboard, which are now included in the ESRI Living Atlas." The data layer Github repo can be found here.
While the spread of the virus is concerning and has impacted and will continue to impact many lives, it is inspiring to see Ember being used as a force for good and helping to inform health care providers, researchers, policy makers and the broader public about how cases are developing across the globe.
Extracted from @NullVoxPopuli'schat project, ember-jsqr is an integration with jsQR, a fast QR code scanner that demonstrates how addon developers may want to integrate with an external library using dynamic import to avoid adding to the initial load cost of an app. The jsQR library itself is 45kb (after min+gzip). This addon adds only bytes to the initial vendor bundle, or the cost of a single Glimmer component, a private service, and modifiers.
Raja S (@srajas0), who has worked with Ember since 2018, recalls their experience of being unable to find many examples of how to write unit, rendering, and application tests. To help others and future Ember developers, Raja has created a demo app that uses QUnit DOM, ember-cli-mirage, and ember-cli-code-coverage for testing.
But even though these APIs are already sufficient to go about our lives as application developers, it is still a limiting way for addon authors to create useful community projects. What if your addon could add teardown work to host apps in a non-hierarchical manner, so it can never conflict with other addon's teardown functionalities?
If you want to know the answer to this question, you shouldn't miss out on reading Chris Garrett's (@pzuraq) recent Request for Comments (RFC) about Destroyables - an API proposal for addon authors and framework contributors. Be sure to join the discussion in the comments section of the original RFC!
