@gramio/scenes

WIP. The API can be changed, but we already use it in production environment.

Usage

import { Bot } from "gramio";
import { scenes, Scene } from "@gramio/scenes";

const testScene = new Scene("test")
    .params<{ test: boolean }>()
    .step("message", async (context) => {
        if (context.scene.step.firstTime || context.text !== "1")
            return context.send("1");

        if (context.scene.params.test === true) await context.send("DEBUG!");

        return context.scene.step.next();
    });

const bot = new Bot(process.env.TOKEN as string)
    .extend(scenes([testScene]))
    .command("start", async (context) => {
        return context.scene.enter(testScene, {
            test: true,
        });
    });

Share state between steps

import { Scene } from "@gramio/scenes";

const testScene = new Scene("test")
    .step("message", async (context) => {
        if (context.scene.step.firstTime || context.text !== "1")
            return context.send("1");

        return context.scene.update({
            messageId: context.id,
            some: "hii!" as const,
        });
    })
    .step("message", async (context) => {
        if (context.scene.step.firstTime || context.text !== "2")
            return context.send("2");

        console.log(context.scene.state.messageId);
    });

Storage usage

import { redisStorage } from "@gramio/storage-redis";

const bot = new Bot(process.env.TOKEN as string)
    .extend(
        scenes([testScene], {
            storage: redisStorage(),
        })
    )
    .command("start", async (context) => {
        return context.scene.enter(someScene, {
            test: true,
        });
    });
