Prettier formatting configuration

Question

I'm pulling my hair trying to configure Prettier formatting for Angular HTML component. I tried different configuration overriding but I can't get what I want.

By default, on VS Code + Prettier, the following markup :

<ng-container *ngIf="emailRef.hasError('email')">A valid email address must be used</ng-container>

is formatted to (because of line length) :

<ng-container *ngIf="emailRef.hasError('email')"
  >A valid email address must be used</ng-container
>

which I don't like at all. I don't want Prettier to split the tag like that. I'd rather prefer :

<ng-container *ngIf="emailRef.hasError('email')">
  A valid email address must be used
</ng-container>

Does anyone knows how to override its default behavior ? I'm OK with the default formatting when multiple attributes are used, like in :

<input
  id="email"
  name="email"
  type="email"
  email
  required
  [(ngModel)]="email"
  #emailRef="ngModel"
/>

Answer 1

What works for me is to add a space between the content and the opening and closing tags:

<ng-container *ngIf="emailRef.hasError('email')"> A valid email address must be used </ng-container>

With the spaces, prettier formats it correctly

I know this question is months old, but I posted something similar on Prettier's issues and found a better solution. Leaving it here for people who land here by search.

Set the option --html-whitespace-sensitivity to ignore and you will get your desired output:

<ng-container *ngIf="emailRef.hasError('email')">
  A valid email address must be used
</ng-container>

Although this is not recommended as whitespace formatting can cause issues like extra spacing around text and stuff, which might affect your UI design's consistency.
