ngx-translate-extract

Extract translatable (ngx-translate) strings and save as a JSON or Gettext pot file. Merges with existing strings if the output file already exists.

Usage

Install the package in your project:

npm install @biesbjerg/ngx-translate-extract --save-dev

Add an extract script to your project's package.json:

"scripts": {
  "extract": "ngx-translate-extract --input ./src --output ./src/assets/i18n/*.json --clean --sort --format namespaced-json"
}

You can now run npm run extract to extract strings.
