Internationalization Piotr Lewandowski
INTERNATIONALIZATION I18N LOCALIZATION L10N
Adapting product to region „look and feel” ! Localization "
Translator
Enables easy localization ! Internationalization " Developer
ANGULAR I18N Dates Currencies Numbers Plurals Translations Grammar forms
WHY OFFICIAL SOLUTION? ngx-translate deprecated official solution not ready?
GOALS Re-use existing standards Process works at scale No rutime
overhead
<h1 i18n>Hello, {{ name }}!</h1> <img src="avatar.png" i18n-title title="It’s you!"
/> <p i18n="UserModule|User Profile"> Last time seen at {{ lastVisited | date }} </p>
PLURAL FORMS
ICU EXPRESSIONS <p>Alicja { count, plural, =0 { nie złapała
Pokémona } one { złapała Pokémona } few { złapała {{count}} Pokémony } many { złapała {{count}} Pokémonów } other { złapała Pokémonów: {{count}} } }</p> Alicja złapała 5 Pokémonów count = 5
XLIFF <trans-unit id="dfd67d0cbc87b3e8b89570c00031a4751cf4b76c" datatype="html"> <source>Hello, <x id="INTERPOLATION" equiv-text="{{name}}"/>!</source> <!-- ...
stuff ... --> </trans-unit> <h1 i18n>Hello, {{name}}!</h1>
ID GENERATION <h1 i18n="@@topbar.header"> Angular is cool </h1> <h1 i18n>
Angular is cool </h1> Custom ID Generated ID hash Content changes = ID changes Never changes
PROCESS Mark HTML with i18n attributes Extract messages from HTML
to XLIFF Copy & translate XLIFF Generate new app version for each language Outside Angular
PAIN POINTS
PAIN POINTS
MULTIPLE BUNDLES
MULTIPLE BUNDLES ! Currently... Everything at build time with AOT
Duplicated builds for each locale " Desired... ONE bundle for all locales Translating before application bootstraps
MULTIPLE BUNDLES ! On the roadmap since 2.0 " Planned
for Ivy compiler # Already in master since June 2018 STATUS
DURING COMPILATION... <h2 i18n="User profile@@page.header"> Hello, Gdańsk! </h2> interface I18nDef
{ value: 'Hello, Gdańsk!'; id?: 'page.header'; meaning?: undefined; description?: 'User profile'; }
MULTIPLE BUNDLES PR #24037 205 review comments J OVERVIEW Loading
BEFORE Angular bootstraps All locales in ONE bundle Choose: AOT or RunTime
IN-CODE TRANSLATIONS
IN-CODE TRANSLATIONS ! Currently... Everything in HTML " Desired... Translation
in services
IN-CODE TRANSLATIONS ! Planned with Ivy compiler " Work in
progress # Polyfill already exists @ngx-translate/i18n-polyfill STATUS
IN-CODE TRANSLATIONS OVERVIEW constructor(i18n: I18n) { this.message = i18n('Speaking at
meetup in {{myVar}} !', { myVar: 'Wrocław, Poland' });
WHY NOT YET RELASED
IS IVY READY YET? Ninety – ninety rule ! Alpha-version
first Last-updated: November 2018
SPECULATIVE FUTURE
ID GENERATION More stable IDs Same IDs for all formats
Migration tool After Ivy
LAZY LOADING Localize single module Better library support See #14331
After Ivy
OPENING THE API Allow custom parsers, generators and loaders →
JSON suport NOT CONFIRMED
TIPS
TSLINT RULE
Enable i18n TSLint rule // tslint.json "i18n": [ true, "check-id",
"check-text" ] * Requires codelyzer Optional, depending on your translation strategy
Enable i18n TSLint rule <h1> Angular i18n is cool </h1>
!
Enable i18n TSLint rule <h1 i18n="@@article.header"> Angular i18n is cool
</h1> !
ENABLE EXTRACTOR
ENABLE EXTRACTOR // package.json "scripts": { "build": "ng build &&
ng xi18n" },
NESTED I18N <div> <div> Angular i18n is cool </div> </div>
! <article i18n> <h1 i18n="@@article.header"> Angular i18n is cool </h1> <p> ... </p> </article> Error: Could not mark an element as translatable inside a translatable section

</form-field>
DETACHED TEXT <form-field> <ng-container i18n> Name </ng-container> <error i18n> Invalid
name </error> </form-field>
WHY OFFICIAL SOLUTION?
BUT... Use whatever fits you
