The i18n library for modern JavaScript

Framework-agnostic. Predictable translation behavior.

npm install intor

Configuration-Centric

Isolation through configuration. No global instance. Behavior stays consistent.

Config 1
Config 2
Config 3
<Component>
t("hello")
<Component>
t("hello")
</Component>
</Component>
<Component>
t("hello")
</Component>

Type-Safe by Design

Type safety covers the full message structure. Across the entire translation call.

ui.title
profile.name
error.message
ui.title
t("ui"), { . . . })
name

Consistent API

One translator interface. Consistent across frameworks and environments.

Clientconst { t } = useTranslator()
Next.js
Serverconst { t } = await getTranslator()
Next.js

Explicit loading

Translations are data. Loading is explicit. Bundle them with the application, or resolve them at runtime through the Loader.

Bundled

Load translations via static or dynamic imports. Included in the application bundle.

Static Importimport EN from "../messages/en/index.json"
Dynamic Importawait import(`../messages/${locale}/index.json`)

Loader

Load translations at runtime. From local or remote sources.

Flexible File Structure
