Question: How to add new language and set it as a default?

KaMeHb-UA commented 6 years ago

I had look on src/reducers/locale/languageType.ts and found my language described (russian), so I created src/locale/ru.json similar to src/locale/en.json and changed exported environment.settings.defaultLanguage to LanguageType.Russian in src/config/environment.dev.ts, but got next error:

TypeError: Cannot read property 'code' of undefined

What I'm doing wrong?

Thanks for asking!😀 I assume that you are using the last version of React Social Network. To set a new language:

Create a copy of en.json in locale folder then rename with the convention {country language code}.json. ( For your case the name of your file would be ru.json). Then translate the file in your language.
Set your file ru.json in localSaga.ts.
- To do that in initLocalization() function add the object { name: 'Russian', code: LanguageType.Russian } to const languages = [ ] array.
- Then add const russianLocale = require('locale/ru.json') which import your file in localeSaga
- By that now you can use yield put(addTranslationForLanguage(russianLocale, LanguageType.Russian)) to add your language in Redux Store.

With this you have your language installed. 👍

However for the debug TypeError: Cannot read property 'code' of undefined mostly cause if you don't use Immutable function to get code value. So please be sure in HomeComponent mapStateToProps() instead of bellow code:

getActiveLanguage(state.locale).code,

You should use :

getActiveLanguage(state.get('locale')).code

As state is Immutable so you need to use get() function to access value.

Let me know if any issue.
