Typed i18next

The generated file augments i18next automatically once it is part of your TypeScript program (import its types anywhere, e.g. in the setup below). Keys work through i18next's own t:

import i18next from "i18next";
i18next.t("common:common.welcome"); // autocompleted, checked

For typed interpolation params, wrap t with the shipped helper:

import i18next from "i18next";
import { createTypedT } from "@language-bridge/cli/runtime";
import type { TranslationParams } from "./@types/resources";

export const tt = createTypedT<TranslationParams>(i18next.t);

tt("common:common.welcome", { name: "Ada" }); // params required + typed
tt("auth:auth.signin");                        // no params -> no second arg

Plural keys (item_one / item_other) collapse to the base key item with a required numeric count.

Generate the file with lb sync (or lb generate); the default output is src/@types/resources.d.ts (--out to change).
