Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Facebook/Google OAuth2 service written in TypeScript

Readme

🧩 multi-oauth2-nodejs

Facebook / Google OAuth2 service được viết bằng TypeScript — dùng đơn giản cho bất kỳ ứng dụng Node.js hoặc Express nào.

🚀 Giới thiệu

  • Thư viện này giúp bạn tích hợp đăng nhập OAuth2 với Google và Facebook một cách nhanh chóng. Nó cung cấp các service sẵn sàng để gọi API xác thực người dùng, và trả về thông tin cơ bản (id, email, name, picture).

📦 Cài đặt

npm install multi-oauth2-nodejs

🧠 Cấu trúc cơ bản

  • Sau khi cài đặt, bạn có thể tạo OAuth2 service cho từng nền tảng như sau:
import express from "express";
import OAuth2Factory, { OAuth2Service } from "multi-oauth2-nodejs/index.js";

const app = express();
app.use(express.json());

// Tạo 2 service OAuth2 cho Google và Facebook
const googleOAuth2Service: OAuth2Service = OAuth2Factory.createService("google", {
  clientId: "GOOGLE_CLIENT_ID",
  clientSecret: "GOOGLE_CLIENT_SECRET",
  redirectUri: "http://localhost:3000/verify/google",
});

const fbOAuth2Service: OAuth2Service = OAuth2Factory.createService("facebook", {
  clientId: "FACEBOOK_CLIENT_ID",
  clientSecret: "FACEBOOK_CLIENT_SECRET",
  redirectUri: "http://localhost:3000/verify/facebook",
});

// ==== ROUTES ====

// Lấy URL để người dùng truy cập vào Facebook login
app.get("/auth/facebook/verify-uri", (req, res) => {
  res.json({
    uri: fbOAuth2Service.getAuthorizationUrl(),
  });
});

// Callback từ Facebook trả về sau khi người dùng đồng ý đăng nhập
app.get("/verify/facebook", async (req, res) => {
  const code = req.query.code as string;
  const user = await fbOAuth2Service.getUserDetails(code);
  res.json(user);
});

// Lấy URL để người dùng truy cập vào Google login
app.get("/auth/google/verify-uri", (req, res) => {
  res.json({
    uri: googleOAuth2Service.getAuthorizationUrl(),
  });
});

// Callback từ Google trả về
app.get("/verify/google", async (req, res) => {
  const code = req.query.code as string;
  const user = await googleOAuth2Service.getUserDetails(code);
  res.json(user);
});

app.listen(3000, () => {
  console.log("✅ Server is running on http://localhost:3000");
});

⚙️ Cấu hình OAuth2

  • Để sử dụng được, bạn cần đăng ký ứng dụng của bạn trong:

    • Google Cloud Console
    • Meta for Developers (Facebook)
  • Và lấy:

    • client_id
    • client_secret
    • redirect_uri

📘 Ví dụ phản hồi từ API /verify/google

{
  "id": "114567834567890",
  "email": "[email protected]",
  "name": "John Doe",
  "picture": "https://lh3.googleusercontent.com/a-/AOh14Ggk...."
}
