What are the best practices for localizing web applications?

1 Use a localization framework

A localization framework is a set of tools and libraries that help you implement localization in your web application. It can handle tasks such as detecting the user's language, loading the appropriate resources, and formatting the output. Some examples of localization frameworks are i18n for Node.js, Django for Python, and Rails for Ruby. Using a localization framework can save you time and effort, as well as ensure consistency and quality across your web application.

2 Follow internationalization standards

Internationalization standards are guidelines and specifications that define how to design and develop web applications that can be easily localized. They cover aspects such as encoding, character sets, fonts, date and time formats, currencies, units of measurement, and directionality. Some examples of internationalization standards are Unicode, ISO 639, and W3C recommendations. Following internationalization standards can help you avoid common errors and compatibility issues, as well as make your web application more accessible and user-friendly.

3 Leverage localization tools

Localization tools are software applications that help you manage and automate the localization process. They can help you with tasks such as extracting and storing strings, translating and editing content, and synchronizing and deploying changes. Some examples of localization tools are Transifex, Crowdin, and Lokalise. Leveraging localization tools can help you speed up and streamline the localization workflow, as well as reduce costs and errors.

4 Use a content management system

A content management system (CMS) is a software application that helps you create and manage web content. It can help you with tasks such as editing, publishing, and updating content, as well as organizing and storing content in different languages. Some examples of CMS are WordPress, Drupal, and Joomla. Using a CMS can help you separate content from code, as well as make it easier to update and maintain your web content.

5 Test your localized web application

Testing your localized web application is a crucial step to ensure that it works correctly and meets the expectations of your target audience. It can help you identify and fix issues such as layout, functionality, usability, and quality. Some methods of testing your localized web application are manual testing, automated testing, and user testing. Testing your localized web application can help you improve your web application's performance and user satisfaction.

6 Hire professional translators

Hiring professional translators is a best practice for localizing web applications that require high-quality and accurate translations. Professional translators can help you with tasks such as translating and proofreading content, as well as ensuring cultural and linguistic appropriateness. Some ways of hiring professional translators are working with a translation agency, using a freelance platform, or hiring in-house translators. Hiring professional translators can help you enhance your web application's credibility and reputation.
