🚀 Get Started • 📚 Documentation • 📦 VSCode Extension • 💬 Discord
npm install -g stringer-cli
If you're updating to a new version and the stringer command doesn't use the latest version, uninstall and reinstall:
# For npm users
npm uninstall -g stringer-cli
npm install -g stringer-cli
# For pnpm users
pnpm uninstall -g stringer-cli
pnpm install -g stringer-cli
This ensures the global symlink is properly updated. The postinstall script will verify your installation automatically.
Stringer CLI is a project by Titus Decali, a full-stack developer living in Seoul, S. Korea.
This project was selected and funded in part by the Korean government's K-Startup Social Venture program in February of 2025.
After the pain of localizing many React and Vue projects using i18n, I decided to build a tool that would make this complex and frustrating process easier for all devs. Stringer handles the intricacies of i18n for you: manually extracting, translating and managing text strings in your app.
The CLI itself is built with Clack and utilizes Stringer's own open-source clack-tree-select prompt for selecting files to process:
clack-tree-select.
Stop wrestling with manual string extraction and translation management. Stringer CLI automates the entire internationalization process, letting you focus on building great products while we handle the complexity of going global.
Beyond simple string extraction, Stringer handles the heavy lifting of i18n configuration—URL-based routing, automatic link prefixing, and even middleware repair to ensure your existing code works seamlessly with i18n routing (without breaking what you've already built). Under the hood, a multi-step processing pipeline combines logical operations with fine-tuned AI to deliver accurate results quickly and affordably.
From this:
<h1>Welcome to our application</h1>
<p>Please enter your email address</p>
To this in seconds:
<h1>{{ t('welcome.9824') }}</h1>
<p>{{ t('welcome.2516') }}</p>
And will even generate the i18n locale files for you!
{
"welcome": {
"9824": "Welcome to our application",
"2516": "Please enter your email address"
}
}

When working with a team, Stringer automatically tracks changes to your base language file via a .stringer-sync.json file in your locales folder. This file should be committed to Git — it enables automatic sync detection across all team members without any additional setup.
Key benefits:
⚠️ Important: Do not add
.stringer-sync.jsonto your.gitignore— this file must be committed to enable team sync.
Add language prefixes to your URLs (e.g., /en/..., /fr/...) to improve global SEO while minimizing risk to existing routing and middleware.
