Internationalization

[wiledusc]

Hey guys,
I'm creating a blog with this template and I would like to know how to add the same posts in different languages.

Hello @wiledusc,

The Internalization (i18n) is something pending. We had given it a low priority assuming that few people could need it, but no. Since you published the issue I've been thinking about it, but to give you a detailed and generic solution we need time to develop and test it.

For now, if you give some details we can talk about a solution that suits your needs. For this, the following doubts come to me mind:

• How are you translating the pages that are not posts? Do you use astro-i18next?
• Do you plan to add languages ​​over time or have you defined the limit number of languages ​​you want to translate into?
• Are the posts still loaded from src/data/posts folder or are loaded from an API?

How are you translating the pages that are not Posts?
Right now I'm just creating the blog in English, but I want to use the astro-i18next.

Do you plan to add languages ​​over time or have you defined the limit number of languages ​​you want to translate into?
I plan to have only Portuguese and English.

Are the posts still loaded from src/data/posts folder or are loaded from an API?
Right now they are loaded froms rc/data/posts folder, but I'm planning to load from an API.

Hi @wiledusc

Here some changes that could work to make your blog multilingual (en, pt). These are ideas that I propose to you assuming that you do not use astro-i18next, you do not need many page translations and you are focused on the posts.

On these days I will make some updates to the template so that it becomes part of the AstroWind core.

Assuming you want the urls like this:

• https://domain.com/en/blog/post-in-english
• https://domain.com/pt/blog/post-in-portuguese

Note: The new folders in data are just for organizing the posts by language, it is not functionally necessary.

Changes in .astro pages related to Blog

Note: First you need to go to this file src/utils/getNormalizedPosts.js and add the mapping of the new frontmatter variables: lang and alternate

[slug].astro

From:

/// (...)
export async function getStaticPaths() {
  const posts = await fetchPosts();
  return posts.map((post) => ({
    params: { slug: post.slug },
    props: { post },
  }));
}

To:

/// (...)
export async function getStaticPaths() {
  const posts = await fetchPosts();
  return posts.map((post) => ({
    params: {
      slug: post.slug,
+     lang: post.lang
    },
    props: { post },
  }));
}
/// (...)

Also you need to get the alternates extracted from the frontmatter of the post and add them to the meta tags of the HTML.

[...post].astro

/// (...)
export async function getStaticPaths({ paginate }) {
  const posts = await fetchPosts();

  return paginate(posts, {
    pageSize: BLOG.postsPerPage,
  });
}
/// (...)

/// (...)
export async function getStaticPaths({ paginate }) {
  const posts = await fetchPosts();
  const postsGroupedByLang = await someSmartFunction(posts);

  return Object.keys(postsGroupedByLang).map( lang => 
    paginate(postsGroupedByLang[lang], {
      params: { lang },
      pageSize: BLOG.postsPerPage,
    })
  );
}
/// (...)

In addition to all this you should also review making changes to the menu (change language), detect default language, SEO aspects, add the lang attribute to the main HTML tag, etc etc.
