do you know Popular dashboard Made by Johns Hopkins University System Science and Engineering Center Is the part used to track Corona COVID-19 virus cases built using Ember.js?

According to reports CSSE Blog, “The dashboard was shared publicly for the first time on January 22, showing the location and number of confirmed COVID-19 cases, deaths and recovery in all affected countries. It was developed to provide a solution for researchers, public health authorities and the public User-a friendly tool to track outbreaks. In addition, all collected and displayed data is provided for free, initially as Google Sheets, now in the GitHub repository, and the functional layer of the dashboard, now included in ESRI Atlas is alive in .” The data layer Github repo can be found Here.

Although the spread of the virus is worrying and has affected and will continue to affect the lives of many people, seeing Ember being used as a force for good and helping inform healthcare providers, researchers, policy makers and the wider How the public has cases is developing on a global scale.

Thank you Rene Rubalkawa (@odoe) in order to tweet This made us realize.

After nine months of hard work, version 3.0.0 ember-models-table Released from beta Oleg Nechiporenko (@onechiporenko).

This major version includes some breaking changes, so please check Release notes When you update.Supplements to the version and a new demonstration of version 3.x Bootloader 3, Bootloader 4, ember-paper with plain-html.

From @NullVoxPopuli Chat item,
man-jsqr Is an integration with jsQR, one quickly QR code scanner, demonstrating how plugin developers might want to integrate with external libraries using the following methods Dynamic import Avoid increasing the initial loading cost of the application. The jsQR library itself is 45kb (after min+gzip).This plugin only adds byte
To the initial supplier bundle, or the cost of individual Glimmer components, private services and modifiers.

QR and barcode scanning will not increase the package size (thanks, Manual automatic import!) can also be in Man scanner.

Raja S (@srajas0)I have been working with Ember since 2018, and recalled that they could not find many examples of how to write units, rendering and application testing.To help others and future Ember developers, Raja created A demo application Use QUnit DOM, ember-cli-mirage and ember-cli-code-coverage for testing.

We encourage you View Raja’s tutorial See how you can improve your test today!

As Ember developers, when components or routes are removed, we benefit from framework cleanup.Most importantly, we can even instruct the components we build to perform additional Disassembly instructions, After Override the willDestroy hook (available in both Ember and Glimmer components).

However, even if these APIs are sufficient for our lives as application developers, for plugin authors, it is still a restrictive way to create useful community projects. What if your plugin can add teardown work to host the application? Unranked Way, so it will never conflict with the disassembly function of other plugins?

If you want to know the answer to this question, you should not miss reading Chris Garrett (@pzuraq) recent Request for Comments (RFC) on Destructible items -API proposals for plugin authors and framework contributors.Remember to join the discussion in the comment area Original RFC!
