Usage as an NPM package

import type { ApiMethods } from "@gramio/types";

type SendMessageReturn = ReturnType<ApiMethods["sendMessage"]>;
//   ^? type SendMessageReturn = Promise<TelegramMessage>

Imports

• methods - exports ApiMethods which describes the api functions
• objects - exports objects with the Telegram prefix (for example Update)
• params - exports params that are used in methods

Write you own type-safe TBA API wrapper

import { stringify } from "node:querystring";
import type { ApiMethods } from "@gramio/types";

const TOKEN = "";

const api = new Proxy<ApiMethods>({} as ApiMethods, {
    get: (_target, method: string) => async (args: Record<string, any>) => {
        const url =
            `http://api.telegram.org/bot` +
            TOKEN +
            "/" +
            method +
            `?` +
            stringify(args);

        const response = await fetch(url, {
            method: "GET",
        });

        const data = await response.json();
        if (!response.ok) throw new Error("some error");

        return data.result;
    },
});

api.sendMessage({
    chat_id: 1,
    text: "msg",
});
