Stimulus 2.0-alpha - What's new?

Light talk about the upcoming features of Stimulus.js.

1. Stimulus 2.0-alpha What’s new?
2. TLDR Two new APIs with a nice surprise
3. Data Map API
4. Data Map API • A way to pass data to a controller. • Use cases: ◦ Storing small strings, such as URLs, dates, or color values; ◦ Bootstrapping a controller with a JSON object or array.
5. HTML Controller
6. However, the Data Map API only works with string values. That means we must manually convert to and from other types as needed
7. Values API
8. Values API • Makes possible to define values (data maps) in the controller itself; • Create properties to accessing them.
9. Usage The Value object keys are Data Map keys, and the values declare their data types
10. Value Properties They work just as the Target API works
11. A nice surprise: Value Changed Callback
12. Usage Now it’s easier to make your good old HTML template look modern
13. How many times have you seen the following pattern?
14. HTML Controller
15. We’re coupling the controller to the class name
16. Maybe using the Data Map API?
17. HTML Controller
18. Classes API
19. HTML Controller
20. All that with a very small cost
21. Unifying target attributes Both syntaxes will be supported, but using the original syntax will display a deprecation message in the developer console
22. Excited? Start using it now! Just add it to your package.json
