@loopstack/oauth-examples

OAuth integration workflow examples for the Loopstack  automation framework.

Two integration patterns demonstrated for two providers. Each provider has:

• A scripted overview/summary workflow — single-pass, hand-rolled tool sequence
• An interactive agent workflow — Claude with the full tool set, OAuth auto-retry

Both shapes share the same OAuth retry pattern: on unauthorized error, launch the OAuth sub-workflow inline, then retry from start.

Install as Source (Recommended)

npx giget@latest gh:loopstack-ai/loopstack/registry/examples/oauth-examples src/oauth-examples

Then register the module:

import { Module } from '@nestjs/common';
import { LoopstackModule } from '@loopstack/loopstack-module';
import { OAuthExamplesModule } from './oauth-examples/oauth-examples.module';
 
@Module({
  imports: [LoopstackModule.forRoot(), OAuthExamplesModule],
})
export class AppModule {}

Install as a Dependency

npm install @loopstack/oauth-examples

import { OAuthExamplesModule } from '@loopstack/oauth-examples';

Required app-module configuration

The Agent examples (GitHub Agent, Google Workspace Agent) use Claude via @loopstack/llm-provider-module — @Global, configured once in your root module to set the default model:

import { Module } from '@nestjs/common';
import { LoopstackModule } from '@loopstack/loopstack-module';
import { LlmProviderModule } from '@loopstack/llm-provider-module';
import { OAuthExamplesModule } from '@loopstack/oauth-examples';
 
@Module({
  imports: [
    LoopstackModule.forRoot(),
    LlmProviderModule.forRoot({ model: 'claude-sonnet-4-6' }),
    OAuthExamplesModule,
  ],
})
export class AppModule {}

OAuthExamplesModule re-imports ClaudeModule, GitHubModule, and GoogleWorkspaceModule. The latter two transitively pull in the global OAuthModule and register the provider implementations — no additional OAuth wiring required in your AppModule. LlmProviderModule.forRoot(...) sets the default model for the agent workflows.

The scripted (non-agent) overview/summary workflows also use Claude for the markdown rendering step, so LlmProviderModule.forRoot(...) is required for them too.

Environment

ANTHROPIC_API_KEY=sk-ant-...
GITHUB_CLIENT_ID=...
GITHUB_CLIENT_SECRET=...
GOOGLE_CLIENT_ID=...
GOOGLE_CLIENT_SECRET=...

Refer to @loopstack/github-module and @loopstack/google-workspace-module for the full OAuth setup (redirect URLs, scopes).

Examples

GitHub Overview

A scripted (non-agent) GitHub workflow that walks every major GitHub read tool: user info, orgs, repo details, branches, issues, PRs, directory contents, workflow runs, and code search. On any unauthorized error it pauses, launches the OAuthWorkflow sub-workflow inline, then retries from the start.

Files

• templates/repoOverview.md — Handlebars markdown summary template

GitHub Agent

An interactive Claude chat agent with 25 GitHub tools wired in: repos, issues, PRs, code, actions, and search. When a tool returns unauthorized, the agent calls authenticateGitHub to launch the OAuth sub-workflow and retries.

• github-agent-example.workflow.ts — workflow class
• github-agent-example.ui.yaml — chat prompt-input widget
• templates/systemMessage.md — system prompt

Google Calendar Summary

Fetches the user’s upcoming calendar events via GoogleCalendarFetchEventsTool and renders a markdown summary. On unauthorized it launches the OAuthWorkflow sub-workflow inline and retries.

Files

• google-calendar-summary-example.workflow.ts — workflow class
• templates/calendarSummary.md — Handlebars markdown summary

Google Workspace Agent

An interactive Claude chat agent with 11 Google Workspace tools (Calendar, Gmail, Drive). When a tool returns unauthorized, the agent calls authenticateGoogle to launch the OAuth sub-workflow and retries.

Files

• google-workspace-agent-example.workflow.ts — workflow class
• google-workspace-agent-example.ui.yaml — chat prompt-input widget
• templates/systemMessage.md — system prompt
