    tldr: ng2-translate, but with positional instead of named arguments, and the support for pluralization, ordinals and a "switch statement" from MessageFormat, with a simpler JSON format that does away with the need for a parser.

Translations are stored in JSON format.
Each translation is stored and retrieved with a key.
Translations can use positional placeholders to be replaced by variables, which are passed as an array of String and/or Number values.
The {r0} placeholder is replaced with the first value from the input array, the {r1} is replaced with the second and so on.
Besides simple replacement, there are other three special placeholders: The Plural placeholder {p0}, the Ordinal placeholder {o0} and the Select or Switch placeholder {s0}. These are inspired by @SlexAxton/messageformat.js, and use the same ICU keys where applicable (zero, one, two, few, many, other).
When the Plural placeholder {p0} is used, the translation file can provide nouns for the appropriate ICU keys (zero, one, many etc.)
For the Selector or Switch placeholder {s0}, the translation file can provide a map of arbitrary keys and values.
Finally, for the Ordinal placeholder {o0}, the translation file can provide the appropriate ordinal number translations.
In addition to the placeholders in the translated string, values passed to the Plural, Selector/Switc and Ordinal placeholders can themselves contain Nested Placeholders in the format {(p|s|o)<input_index>.<arbitrary_key>}. For example: {p0.1}.
An Angular service would be provided to select and load language JSON files, as well as a simple translate(msg:string, input:Array) method.
A TranslatePipe could be provided as well, mimicking @ocombe/ng2-translate:
@Compoenent({
  template: `
    <div class="notifications">{{ "new-notifications" | translate[unreadNotifications.length] }}</div>
    
    <a (click)="loginWithGoogle()">{{ "login-with" | translate["Google"] }}</a>
    <a (click)="loginWithGitHub()">{{ "login-with" | translate["GitHub"] }}</a>
    
    <div class="assistant-research-results">
      {{ "found-x-in-nth-cat" | tanslate[assistant.gender, results.length, category.index] }}
    </div>
  `
})
This gist includes the example translation files en.json and pt.json. Note that in the Portuguese translation, one of the replacement values required a Nested Replacement, written as {p1.0}.
