ionic 4/5 using ngx-translate auto add to subtitle files in i18n

Issue

Is there a way to auto add translation words to i18n folders? Is there a way to automatically add subtitle words to i18n folders?

Using below url https://ionicframework.com/docs/v3/developer-resources/ng2-translate/

When I add below lines as an example:

<ion-title>{{ 'HELLO' | translate }}</ion-title>
<p>{{ 'HI' | translate }}</p>

I expect to find under files ./assets/i18n/en.json ./assets/i18n/es.json

{
  ...
  "HELLO": "HELLO",
  "HI": "HI"
}

After that, it is easier to update json files.

Solution

Sure, ngx-translate-extract does exaclty what you need.

{
    "scripts": {
      "i18n:init": "ngx-translate-extract --input ./src --output ./src/assets/i18n/template.json --key-as-default-value --replace --format json",
      "i18n:extract": "ngx-translate-extract --input ./src --output ./src/assets/i18n/{en,da,de,fi,nb,nl,sv}.json --clean --format json"
    }
}
