Personality Insights Nodejs Starter Application

The IBM Watson Personality Insights service uses linguistic analysis to extract cognitive and social characteristics from input text such as email, text messages, tweets, forum posts, and more. By deriving cognitive and social preferences, the service helps users to understand, connect to, and communicate with other people on a more personalized level.

i18n Support

The application has i18n support and is available in English and Spanish. The language is automatically selected from the browser's locale.

To add a new translation follow the steps below:

Translating the static text: 1. Locate the en.json file present in the i18n directory. This file includes all the messages and labels in English. 1. Copy en.json and name the new file with the format ll-CC.json or ll.json, where ll is the language code and CC is the country code. For example, a new translation for argentinian Spanish would be named after es-AR.json. You may omit the country code to make the translation global for the language. 1. Translate each English string to the desired language and save it.
Translating the personality summary: 1. Locate the JSON files present in public/json/ directory. These are: * facets.json * needs.json * summary.json * traits.json * values.json 1. Copy each file and name it with the format <filename>_ll-CC.json or <filename>_ll-CC.json. For example, a Portuguese language translations for facets.json will result in a new file named facets_pt.json, an UK English translation for traits.json will result in a new file named traits_en-UK.json. 1. Translate all the strings present in the new files to the desired language and save them.
