Don’t Let AI Erase The Next Generation Of Dev Leaders

Don’t let AI erase the next generation of dev leaders

As AI tools take over more routine coding work, some companies are cutting early-career dev roles — a short-sighted move that could quietly erode the next generation of tech leaders if we aren’t careful.

  1. Hi friend. It is a great article, With your tutorial I have set i18n in my next.js application with Lingui.js thanks.
    But I come with some issues that I resolve, may be it will help other if it happens.

    NB: I don’t use Typescript

    1
    – I get Module not found: Can’t resolve ‘fs’ when I add Lingui configurations and tools
    – to fix: configure .babelrc like this
    {
    “presets”: [“next/babel”],
    “plugins”: [“macros”]
    }

    2
    – In most Next.js application folder I think we don’t have “src” folder so the path where Lingui will look at translation can be an issue if they start with “src”, lingui extract will not return any data

    3
    – “npm run lingui extract” result as an issue because we don’t setup the script.
    – to fix: in script of package.json we can add :
    {
    “extract”: “lingui extract”,
    “compile”: “lingui compile”
    }

    4
    – In _app.js I remove “firstRender.current” because it blocks the rendering when I change the language in my menu.

    But again thank you I set translation in my app and may be I’ll add NEXT_LOCALE.
    Great article.

  2. Thanks, If you have any problems with the code you can file an issue on the github repo, and we can take it from there.

  3. Thank you for the writeup, wondering why you put the code for loading translations inside getStaticProps? This means you have the overhead of adding the same code to every page that relies on translated content. Wouldn’t offloading the message loading to _app also work, where you have access to the routers locale and can act accordingly?
    Cheers

  4. Hey, the locale works only If I visit the index root, but I load another url in my website, the locale doesnt work… the locale doesnt appear in my url. Do you know why?

  5. Hi Ivan, thank you for the great tutorial. I’m trying to migrate to App Router atm. Are you aware of any tutorial where the App Router is being used?
