src/index.ts

import { App } from '@slack/bolt';
import { ConsoleLogger, LogLevel } from '@slack/logger';
import { Sequelize } from 'sequelize';
import { SequelizeInstallationStore } from 'slack-bolt-sequelize';

const logger = new ConsoleLogger();
logger.setLevel(LogLevel.DEBUG);

const sequelize = new Sequelize('sqlite::memory:');
const installationStore = new SequelizeInstallationStore({
  sequelize,
  clientId: process.env.SLACK_CLIENT_ID,
  logger,
});

const app = new App({
  socketMode: true,
  appToken: process.env.SLACK_APP_TOKEN,
  signingSecret: process.env.SLACK_SIGNING_SECRET,
  clientId: process.env.SLACK_CLIENT_ID,
  clientSecret: process.env.SLACK_CLIENT_SECRET,
  stateSecret: process.env.SLACK_STATE_SECRET,
  scopes: ['commands', 'chat:write', 'app_mentions:read'],
  installerOptions: {
    directInstall: true,
  },
  installationStore,
  logger,
});

app.event('app_mention', async ({ event, say }) => {
  await say({
    text: `<@${event.user}> Hi there :wave:`,
    blocks: [
      {
        type: 'section',
        text: {
          type: 'mrkdwn',
          text: `<@${event.user}> Hi there :wave:`,
        },
      },
    ],
  });
});

(async () => {
  await app.start();
  logger.info('⚡️ Bolt app is running!');
})();

Run the app
