Summary

LINEAR:
DEVPORT-9: Developer Portal Translation Infrastructure

[JoblersTune]

We should add info to the README about how to handle and maintain translations

[JoblersTune]

We need a redirect from /developers/blog/es to /developers/es/blog/
And from /developers/blog/el-universo-interledger/ to /developers/es/blog/el-universo-interledger

[JoblersTune]

If you navigate to page 2 of the blog posts view (when there are not two pages of Spanish posts), and then choose to switch to Spanish you get an error

Perhaps by default we should return page 1 results every time you switch languages?

[JoblersTune]

If we add dummy Spanish posts you'll see that pagination divides the pages appropriately but clicking to view pages links back to English pages and doesn't maintain the Spanish navigation.

The arrows work, but not the numbers

There is a realted issue -> https://linear.app/interledger/issue/DEVPORT-29/clicking-the-page-navigation-numbers-clears-the-tag-filter
So we can break this out into that issue if needed.

[JoblersTune]

If you navigate to a blog post that is only in English (e.g. /developers/blog/web-monetization-wrapped-2025) and then select to see the page in Spanish (/developers/es/blog/web-monetization-wrapped-2025) the URL changes but the language selector still highlights EN

This means, for instance, that the menu still displays in English

Ideally we'd switch to Spanish navigation and then have a Spanish disclaimer, like we do for the foundation blog.

[JoblersTune]

When you are inside a Spanish blog, there is no menu feedback

I created new Linear issues for non urgent fixes:

• DEVPORT-30:

  • Handle switching to ES for blogs that don;t have a spanish translation

  • from /developers/blog/es to /developers/es/blog/ and from /developers/blog/el-universo-interledger/ to /developers/es/blog/el-universo-interledger

• DEVPORT-32: Document translation handling in README
