@deploybaseline/slack

Slack API emulator for local development and tests: auth, chat, conversations, users, profiles, presence, files, pins, bookmarks, views, reactions, team, OAuth, incoming webhooks, interactivity, slash commands, Socket Mode, and an inspector.

Part of Baseline: local drop-in replacement services for CI and no-network sandboxes.

Usage

npx @deploybaseline/cli start --service slack

Socket Mode needs the opt-in WebSocket package next to the CLI:

npx -p @deploybaseline/cli -p @deploybaseline/ws baseline start --service slack

In tests:

import { createEmulator } from "@deploybaseline/cli";
import { WebClient } from "@slack/web-api";

const slack = await createEmulator({ service: "slack" });
const client = new WebClient("xoxb-local-test", { slackApiUrl: `${slack.url}/api/` });

await client.chat.postMessage({ channel: "general", text: "Hello" });
await slack.close();
