Dblatcher/apps email sign up placement 2

[dblatcher]

What does this change?

[no visible changes] Defines a function to insert a NewsletterSignup element into an Item.body in apps rendering, if the article has a promotedNewsletter and is "Standard" (IE does not a blog, interactive page etc). The function is not called as the component to be rendered is no functional yet.

The exported insertNewsletterIntoItem function will try to insert a NewsletterSignUp according to the following rules:

• Don't put straight after bold text
• Don't put under headings
• Must have plain body text above and below
• Must be within 3 elements from the middle of the article
• Should not be next to an adSlot
• The best place is the last place meeting the criteria above.

If no suitable place is found, the article body is not modified.

How to trial

In "apps-rendering/src/server/page.tsx", import the function and add the following the render function before the call to renderBody on line 186.

	item.promotedNewsletter = {
		kind: 0,
		value: {
			identityName: 'patriarchy',
			description:
				'Reviewing the most important stories on feminism and sexism and those fighting for equality',
			name: 'The Week in Patriarchy',
			frequency: 'Weekly',
			theme: 'opinion',
			successDescription: 'signed up',
		},
	};
	insertNewsletterIntoItem(item);

Why?

The new sign-up blocks are implemented on DCR and the equivalent feature is being rolled out on App-rendering. When the NewsletterSignup is functional, the placement logic can be used to add the NewsletterSignUp BodyElement to the Item.
