Example for retrieving Stories, via Storyblok Management API with translated fields with `__i18n__<langcode>` suffix

stories-list.js

// 1. Import the Storyblok client
import StoryblokClient from "storyblok-js-client";
const spaceId = 325423;

// 2. Initialize the client with the oauth token
// from the my account area at https://app.storyblok.com
const Storyblok = new StoryblokClient({
  oauthToken: process.env.STORYBLOK_OAUTH_TOKEN,
});
// Select all the stories (eventually you can filter only the needed story)
let response = await Storyblok.get("spaces/" + spaceId + "/stories/", {
  // additional query parameters to filter the stories
});
response.data.stories.forEach(async (story) => {
  // retrieving the story
  let responseStory = await Storyblok.get(
    "spaces/" + spaceId + "/stories/" + story.id,
    {},
  );
  let currentStory = responseStory.data.story;
  // for demostration purpose i will print the headline field only for the story "welcome-to-mars"
  if (currentStory.slug === "welcome-to-mars") {
    // Retrieving the field named "headline
    console.log(
      "Headline in default language: " + currentStory.content.headline,
    );
    // appending `__i18n__` + language code for retrieving the translated headline field
    console.log(
      "Headline in it language: " + currentStory.content.headline__i18n__it,
    );
    console.log(
      "Headline in es language: " + currentStory.content.headline__i18n__es,
    );
    // in the case a field is not translated (in my case headline in es is not yet translated) i will see `undefined`
    /*
      The output in my case (where i have headline translated only in italian lang:)
      Headline in default language: Welcome to Mars
      Headline in it language: Benvenuti
      Headline in es language: undefined
      */

    /*
      console.log(" A totally different approach is to use the export endpoint, useful in case you have complext richtext")
      let responseExportStory = await Storyblok.get("spaces/" + spaceId + "/stories/" + story.id + "/export.json", {
        "lang_code" :  "it",
        "export_lang": true,
        "version": 2
      })
      console.log(responseExportStory.data)
       */
  }
});
