Key Referencing

You can reference specific keys within other keys in the same translation file. This feature allows for dynamic translations, where one key can depend on another.

Example:

en.json

{
  "alert": "alert {{value}} english",
  "home": "home english",
  "fromList": "from {{home}}"
}

In this case, calling service.translate('fromList') will return: "from home english".

Key Referencing Within Scopes

When using key references inside a scope, be sure to prefix the referenced key with the scope name.

Example:

admin/en.json

{
  "alert": "alert {{value}} english",
  "home": "home english",
  "fromList": "from {{admin.home}}"
}

Here, calling service.translate('admin.fromList') will return: "from home english".

Passing Parameters to Reused Keys

You can also pass parameters to the reused key. This allows you to dynamically insert values into the translation.

Example:

en.json

{
  "hello": "Hello {{name}},",
  "greet": "{{hello}}, have a good day!"
}

In this case, calling service.translate('greet', {name: 'John'}) will return: "Hello John, have a good day!".

Avoid Circular References

Be cautious when creating key references that may result in circular references. This can lead to infinite loops and unexpected behavior.

Example:

en.json

{
  "key": "{{key2}}",
  "key2": "{{key}}"
}

This will create a circular reference, which should be avoided.
