Lowcoder Translation Script

This script is used to automatically update translation files for Lowcoder using DeepL as translation provider. It allows you to keep your non-English translation files in sync with the master English translation, and automatically fill any missing keys.

Translation Files Structure

The translation files follow a very simple ES Module export format.

English file (en.js — master file):

export const en = {
  "productName": "Lowcoder",
  "productDesc": "Create software applications for your company and customers with minimal coding experience. Lowcoder is an excellent alternative to Retool, Appsmith, and Tooljet.",
  "create": "Create",
  "api": {
    "publishSuccess": "Published Successfully",
    "recoverFailed": "Recovery Failed",
    "needUpdate": "Your current version is outdated. Please upgrade to the latest version."
  },
  ...
};

Target language files (de.js, fr.js, etc):

export const de = {
  ...en,
  "productName": "Lowcoder",
  "productDesc": "",          // missing translation will be auto-filled
  "notSupportedBrowser": "Ihr aktueller Browser ist möglicherweise nicht kompatibel...",
  "create": "Erstellen",
  "api": {
    ...en.api,

  "publishSuccess": "Erfolgreich veröffentlicht",
  "recoverFailed": "Wiederherstellung fehlgeschlagen",
  "needUpdate": "Deine aktuelle Version ist veraltet. Bitte aktualisiere auf die neueste Version.",
  },
  ...
};

Missing or empty keys will be automatically translated and filled.

How The Script Works

Uses en.js as master translation source.
Loads the target language file (e.g. de.js).
Recursively checks all keys.
For any missing keys or empty values, uses DeepL API to translate from English.
Safely preserves placeholders (e.g. {name}, {count}) during translation.
Saves the updated file as de-updated.js (non-destructive overwrite).

Folder Structure

All translation files and the script should be located inside:

/translations/locales/
    ├── en.js
    ├── de.js
    ├── fr.js
    └── translate.js

🚀 Running The Script

You must execute the script from inside the /translations/locales/ directory.

cd translations/locales
node translate.js <targetLang> <targetFile> <deeplApiKey>

Example:

node translate.js de ./de.js YOUR_DEEPL_API_KEY

Where:

de — The target language code (ISO 639-1, e.g. de, fr, es, it, etc.)
./de.js — Path to the existing target translation file.
YOUR_DEEPL_API_KEY — Your personal DeepL API key.

DeepL API Key

You need a valid DeepL API Key to perform automatic translations.

You can get a free developer account at https://www.deepl.com/pro-api
Store your key securely.

Notes

The script preserves all existing translations.
Only missing or empty fields will be translated.
Placeholders inside curly braces (e.g. {count}, {userName}) are automatically detected and protected.
Output will be saved into a new file de-updated.js to avoid overwriting your existing file directly.

Typical Workflow

1️⃣ Start by maintaining your master file en.js with new keys. 2️⃣ Update (or create) your target language file (e.g. de.js), even if empty. 3️⃣ Run the script to automatically fill in missing keys.

node translate.js de ./de.js YOUR_DEEPL_API_KEY

4️⃣ Review and manually adjust translations if needed. 5️⃣ Rename or replace de-updated.js into de.js after verification.

Happy Translating! 🌍
