The Basics

What Is Vibe Coding?

Put simply, vibe coding means using AI coding agents to help you write software. You describe what you want in plain language, then tools like Claude Code, Codex, and Doubao generate or modify the code while you run the app, review the results, and keep refining it.

That does not mean you can get away with knowing nothing about code. A better way to think about it is this: you decide what to build, make the trade-offs, and check the final result, while AI handles much of the hands-on implementation.

What Is a Web App?

A web app is an application you access through a browser. Google, Bing, tanvibecoding.com, online tools, and admin dashboards are all common examples.

Web apps are only one type of software. Others include:

  • Desktop applications such as Chrome, VS Code, and Codex
  • Mini programs
  • Mobile apps such as TikTok and Taobao
  • Browser extensions

Web apps are a great place to start with vibe coding. Users do not need to install anything, you can see most changes by simply refreshing the browser, and once the app is ready, you can share it with a link.

Development

A web app usually has two main parts:

  • A server: Handles business logic, stores data, and provides APIs. It can be built with Java, PHP, JavaScript, or many other languages.
  • A front end: Everything the user sees and interacts with, usually built with HTML, CSS, and JavaScript.

Small projects do not always need a full server and database from day one. A calculator or a simple to-do list can run entirely in the browser. You can add a backend and database later when you need features such as user accounts, shared access, or persistent data.

Why JavaScript?

Because you can use it across the entire stack. JavaScript runs in the browser on the front end and on the server with Node.js. There are also mature npm packages for building interfaces, APIs, database integrations, and deployment workflows.

For vibe coding, a consistent tech stack means less context for the AI to juggle and fewer moving parts when something breaks. As the project grows, you can switch to TypeScript for stronger type checking.

Why Start with a Template?

When you are just getting started, there is no need to get stuck on every technical choice at once:

  • React or Vue?
  • Next.js or TanStack Start?
  • D1 or Supabase?
  • Build authentication yourself or use a third-party service?

It is easy to lose more than ten hours comparing these options, only to discover a fresh set of problems behind each one. AI can generate a stack from scratch, but there is little reason to repeat the same setup work when a proven template already exists.

Popular templates include ShipFast, ShipAny, TinyShip, and TanStarter. Choose one based on who maintains it, where you plan to deploy, and which technologies it uses. A template does not need to be packed with features. It only needs to cover what your project needs right now.

A Simple Development Workflow

  1. Define the problem your first version should solve, and focus on one core flow.
  2. Let the AI inspect the project structure before asking it to change the code.
  3. Build one small feature at a time. Run and test each change instead of saving all the debugging for the end.
  4. Do not stop at checking whether the page looks right. Click through it and make sure the data is actually saved and still there after a refresh.
  5. Keep API keys and database passwords in environment variables, never in front-end code.

Deployment

Once the app is finished, how do you let people use it? You cannot exactly send them to localhost:3000.

You need to put the code on an internet-connected platform so other people can access it. That process is called deployment.

Popular options include Cloudflare, Vercel, and Netlify. You can also rent and manage your own server.

Why Cloudflare?

Cloudflare is a good option for beginners because it brings domains, HTTPS, CDN delivery, static pages, and backend APIs together on one platform. Once you connect a Git repository, new commits can be built and deployed automatically, without requiring you to maintain a server yourself.

With Cloudflare Workers, you can deploy front-end assets and API endpoints together. If you need a database, file storage, or a simple cache, you can add services such as D1, R2, and KV as needed. The cost is usually low for personal projects and early prototypes, although you should always check the latest plan limits before launching.

Cloudflare is not the only good choice. If your project depends heavily on a traditional Node.js runtime, needs a more advanced relational database, or already fits well with Vercel or another cloud platform, choose what suits the project. There is no reason to migrate just for the sake of a free tier.

The Basic Deployment Process

  1. Push your code to GitHub.
  2. Import the repository into your deployment platform and enter the build command.
  3. Configure your environment variables.
  4. Test everything on the temporary domain, then connect your real domain once it is working properly.

Final Thoughts

Vibe coding lowers the barrier to writing software, but it does not make product decisions for us. For a beginner, the simplest path is to pick a small problem, choose a suitable JavaScript template, let AI help you build it step by step, and deploy it as early as possible.

Get one small but complete web app working first. You can learn more about frameworks, databases, and performance optimization as you go. That is usually far more effective than trying to settle every technical decision before you have built anything.
