translate-client-js

What is it ?

It's a javascript client to use translate api.

How does it work ?

Technical stack

• ECMAScript 6 to use last functionalities like class, promise, async/await, etc... http://es6-features.org
• Webpack to manage modules https://webpack.js.org/
• Babel to compile the javascript to be compatible with old browsers https://babeljs.io/
• Tools executed with Node.js version 10 https://nodejs.org/en/
• ESLing to linting the code https://eslint.org/

How to install it and modify it

• Execute command npm ci
• Generate development file: execute command npm run start (result path: dist/translate.js)
  It will keep a process to re-generate the file each times you change the sources
• Generate dist file: execute command npm run build (result path: dist/translate.js)
• Execute unit tests: execute command npm run test (code coverage page path: coverage/lcov-report/index.html)
• When you push your changes, don't forget to generate dist file !
• Update the npm package: npm login(to log with yoctu account) and npm publish(don't forget to change version in package.json)

How to integrate it

How to get the client

Without ES6 modules

• Fetch the project files (download, clone, etc...)
• Add a <script> to use file in dist/translate-client.js

With ES6 modules

• Fetch the project files (download, clone, etc...)
• Import the client with import TranslateClient from 'translate-client-js''

How to use it

• Create a new instance of Translate with var translateClient = new TranslateClient(config)
  Here is the default configuration :
  

{
    baseUrl: '',
    defaultLanguage: 'fr_FR',
    fallbackLanguage: 'en_US',
    namespace: '',
    cacheDuration: 86400,
    localStorageKey: 'translations'
} 

• Call translate method translateClient.translate(key)
  The translate method will return a promise (check https://developer.mozilla.org/fr/docs/Web/JavaScript/Reference/Objets_globaux/Promise)
• Use the promise
  

translateClient.translate(key)
    .then(function(translation) {
        console.log('Result: ' + translation);
    })
    .catch(function(error) {
        console.log(error);
    });

• You can use translateClient.translateMultiple(keys) to translate an array of keys. It return the same type of promise as translateClient.translate(key)
• You can use translateClient.getAllTranslations() to have an object with all the keys and theirs values. It return the same type of promise as translateClient.translate(key)
