## NEW: Reactive Forms guide (2017-01-31)
|
||||
The new [**Reactive Forms**](reactive-forms.html) guide explains how and why to build a "reactive form".
|
||||
"Reactive Forms" are the code-based counterpart to the declarative "Template Driven" forms approach
|
||||
introduced in the [Forms](forms.html) guide.
|
||||
Check it out before you decide how to add forms to your app.
|
||||
Remember also that you can use both techniques in the same app,
|
||||
choosing the approach that best fits each scenario.
|
||||
|
||||
## NEW: Deployment guide (2017-01-30)
|
||||
The new [Deployment](deployment.html) guide describes techniques for putting your application on a server.
|
||||
It includes important advice on optimizing for production.
