Tools: Automatically translate your i18n messages while you develop

What is Interceptor? ## Quick start ## Why this matters during development ## Works with your stack ## Try it out Missing translations slow teams down. You add a string, run the app, and your UI shows a raw key or a fallback. Then someone forgets to fill it later, and you ship partial locales. Interceptor fixes this by automatically translating your i18n messages while you develop. @wrkspace‑co/interceptor is an on‑demand translation compiler that: It supports popular libraries like react-intl, i18next, vue-i18n, and custom t() calls. It’s TypeScript‑first, and includes watch mode + batching. Create interceptor.config.ts: When you’re iterating fast, missing translations are easy to ignore. Interceptor helps you keep locale files complete as you code, so your UI always reflects the current language state. You get: Interceptor is designed to fit into modern tooling: Webpack plugin example: Repo: https://github.com/wrkspace-co/Interceptor MIT‑licensed. If you’ve been battling missing i18n keys during development, I’d love feedback — especially edge cases, new library support, or workflow ideas. Templates let you quickly answer FAQs or store snippets for re-use. Are you sure you want to hide this comment?
