Feb 1, 2025February 2025 – Must/ Mustang repository (mustang-im/mustang) performance-focused monthly summary. Overview: Delivered two high-impact initiatives to increase build reliability and scale localization capabilities, enabling faster multi-language releases and reducing manual translation effort. Key features delivered: - Internationalization overhaul: migrated i18n to FormatJS runtime, introduced a lightweight L10n, implemented Vite-based string extraction, and integrated DeepL-derived translations with an automated CI workflow for translations. Major bugs fixed: - E2 build Conditional Compilation: fixed non-functioning conditional compilation by wiring in vite-plugin-conditional-compile to honor the isWebMail flag during build (commit dd8893934b7a58c0747042ee0798946282f7c473). Overall impact and accomplishments: - Improved build reliability for E2 pipelines and established a scalable localization pipeline, reducing manual translation effort and accelerating multilingual feature releases. - Demonstrated strong tooling and automation skills, with end-to-end localization workflow support from extraction to deployment. Technologies/skills demonstrated: - Vite, FormatJS runtime, custom L10n implementation, translation automation, DeepL integrations, CI workflows, and plugin integration (vite-plugin-conditional-compile).
