# ng2-translate-extract
Extract translatable (ng2-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/ng2-translate-extract --save-dev`

Add an `extract` script to your project's `package.json`:
```
"scripts": {
  "extract": "ng2-translate-extract --dir ./src --output ./ --format=json --clean"
}
```
You can now run `npm run extract` to extract strings from your project's `src` dir. The extracted strings are saved in `JSON`-format in your project's root.

Modify the scripts arguments as required.
