Usage

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 a script to your project's package.json:

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

You can now run npm run extract-i18n and it will extract strings from your project.

Examples

Extract from dir and save to file

ngx-translate-extract --input ./src --output ./src/assets/i18n/template.json

Extract from multiple dirs

ngx-translate-extract --input ./src-a ./src-b --output ./src/assets/i18n/template.json

Extract and save to multiple files using path expansion

Note: This method does not work on Windows!

ngx-translate-extract --input ./src --output ./src/i18n/{da,en}.json

On Windows you must specify each output destination individually:

ngx-translate-extract --input ./src --output ./src/i18n/da.json ./src/i18n/en.json

JSON indentation

Tabs are used by default for indentation when saving extracted strings in json formats:

If you want to use spaces instead, you can do the following:

ngx-translate-extract --input ./src --output ./src/i18n/en.json --format-indentation ' '

Mark strings for extraction using a marker function

If, for some reason, you want to extract strings not passed directly to TranslateService's get() or instant() methods, you can wrap them in a marker function to let ngx-translate-extract know you want to extract them.

Install marker function: npm install @biesbjerg/ngx-translate-extract-marker

import { marker } from '@biesbjerg/ngx-translate-extract-marker';
 
marker('Extract me');

Add the marker argument when running the extract script:

ngx-translate-extract ... -m extract

You can alias the marker function if needed:

import { marker as _ } from '@biesbjerg/ngx-translate-extract-marker';
 
_('Extract me');

ngx-translate-extract ... -m _
