From 6ada8549f868a5032857dd710075f1e55210a62d Mon Sep 17 00:00:00 2001 From: Helge Sverre Date: Thu, 29 Oct 2026 10:46:15 +0100 Subject: [PATCH 1/2] feat: translate link preview titles and descriptions with the post Translate on a post now also translates the title and description of its link preview. Translations are cached by the preview's content, so posts linking the same page share one. A failed preview translation is reported and the post is still shown translated. --- app/Actions/CreateCommitTranslation.php | 62 ++++++++++++++++ app/Ai/Agents/LinkPreviewTranslator.php | 57 ++++++++++++++ app/Services/CommitTranslations.php | 52 ++++++++++++- resources/js/components/commit-card.tsx | 4 +- resources/js/components/commit-thread.tsx | 4 +- .../js/components/commit-translation.tsx | 6 +- resources/js/types/commit.ts | 4 + .../CommitTranslationControllerTest.php | 74 +++++++++++++++++++ 8 files changed, 259 insertions(+), 4 deletions(-) create mode 100644 app/Ai/Agents/LinkPreviewTranslator.php diff --git a/app/Actions/CreateCommitTranslation.php b/app/Actions/CreateCommitTranslation.php index 83607841f..91c4e34a8 100644 --- a/app/Actions/CreateCommitTranslation.php +++ b/app/Actions/CreateCommitTranslation.php @@ -5,9 +5,11 @@ namespace App\Actions; use App\Ai\Agents\CommitTranslator; +use App\Ai\Agents\LinkPreviewTranslator; use App\Enums\CommitStatus; use App\Exceptions\CommitProcessingFailed; use App\Models\Commit; +use App\Models\LinkPreview; use App\Services\CommitTranslations; use Illuminate\Support\Facades\Cache; use Illuminate\Support\Facades\DB; @@ -21,7 +23,32 @@ public function __construct(private CommitTranslations $translations) // } + /** + * Detects the post's language, or translates it into the given language along with the title and description of + * its link preview.
