Css keeps validating
It turns out, that the construnctor of From Control does not only take the default value, but also an array of validators.
So let's make all of our fields required like this: Now that we have talked about the first use-case that comes to mind, let's talk about the second one: email address validation.
This article describes helpful patterns for testing styled-components with Jest snapshots. We want them to be a fail-safe in case something breaks unexpectedly, but don’t expect them to lead your component design process or validate component behavior.
Snapshot tests provide really helpful validation to ensure styles stay consistent. Snapshots provide detailed feedback, but it can be overwhelming and difficult to diagnose for large, complex components.
I’ve added a companion repo on Github for this article, if you’d like to code-along. A recent article, Structuring Our Styled Components, describes helpful patterns for keeping your components manageable. This immediate failure feedback is incredibly helpful for pinpointing the issue.
It’s challenging to remember context after making large changes. One of the strongest criticisms against snapshots is unclear intent, and that’s a fair critique.
A final 👍 is really helpful for the reviewer when a PR is submitted.
To do that properly, it requires a list of validators that are specific to the input of the form.To create that component we again use the angular cli: That's all we need to add to our for now. We also assign each field of our Form Control to one HTML-Element using "form Control Name".Now that we have our Form Control, it is time to define the visuals in our template. You might have noticed, that we are using our first form of validation here.In this tutorial you are going to learn how you can validate your angular reactive forms.We are going to create a basic form and discover, how we can validate each field using angular validators.
This obscurity can lead to frustration and tempt you to blow away the snapshot. Keep in mind that you can minimize this frustration by following the previous two tips.
