Project Scaffolding Showdown: create-react-app vs degit vs sao

When kicking off a new JavaScript project, you rarely start from scratch. Instead, you use a scaffolding tool to generate a baseline structure. But not all tools serve the same purpose. create-react-app, degit, and sao each solve different problems in the project initialization workflow. Let’s break down how they work, when to use them, and what trade-offs they involve.

🧱 Core Philosophy: Opinionated Stack vs Template Copier vs Generator Engine

create-react-app is an opinionated, full-stack setup for React apps. It bundles Webpack, Babel, ESLint, Jest, and more into a single dependency, hiding configuration behind a stable abstraction.

# One command gives you a complete dev environment
npx create-react-app my-app

It assumes you’re building a React app and provides everything needed out of the box — including hot reloading, testing, and optimized production builds.

degit is a dumb file copier. It clones a Git repo but strips away the .git folder and history, leaving only the raw files. There’s no logic, no prompts, no transformation.

# Copies files from a repo as plain text
npx degit user/repo my-project

Think of it as git clone --depth 1 followed by rm -rf .git, but faster and more reliable for templates.

sao is a programmable scaffolding engine. You write a sao.js config file that defines prompts, file templates, and actions. When run, it asks questions and generates a tailored project.

# Runs a generator (published as an npm package or local path)
npx sao my-generator my-project

It’s designed for authors who want to distribute reusable, interactive project starters.

🛠️ Template Handling: Static vs Dynamic Generation

create-react-app uses a fixed, internal template. You can’t change it without ejecting (which exposes all config and makes updates impossible). The template includes React, ReactDOM, and basic CSS support.

// No user-facing template customization
// The template is hardcoded in the package

degit copies static files verbatim. If your template has {{name}} placeholders, they stay as literal text unless you add your own post-processing.

# Template file: src/index.js
console.log('Hello from {{projectName}}!');

# After degit:
# File remains unchanged — no variable substitution

sao supports dynamic templating using EJS-like syntax. It processes files through a template engine, replacing variables based on user answers or context.

// sao.js generator config
export default {
  prompts: [{ name: 'name', message: 'Project name?', default: 'my-app' }],
  actions: [{ type: 'add', files: '**', templateDir: 'template' }]
};

// template/src/index.js
console.log('Hello from <%= name %>!');

// Output after running sao:
// console.log('Hello from my-cool-app!');

💬 User Interaction: Silent vs Interactive Setup

create-react-app is non-interactive. It takes a project name and runs. No questions asked. This ensures consistency but offers no flexibility during creation.

npx create-react-app dashboard  # Done. No prompts.

degit is also non-interactive. It’s a fire-and-forget copy operation. Great for scripts or CI, but not for guided setups.

npx degit vitejs/vite my-app  # Copies instantly

sao is built for interaction. It uses Inquirer.js under the hood to ask questions, validate input, and branch logic.

// sao.js
export default {
  prompts: [
    { name: 'typescript', type: 'confirm', message: 'Use TypeScript?' },
    {
      name: 'lint',
      type: 'confirm',
      message: 'Add ESLint?',
      when: answers => answers.typescript // Only ask if TS is chosen
    }
  ]
};

This makes it ideal for public generators where users expect choices.

📦 Extensibility and Maintenance

create-react-app is not extensible without ejecting. Once you eject, you own all 50+ config files forever. The React team explicitly discourages ejecting and focuses on keeping the default setup modern via upgrades.

# Ejecting is a one-way door
npm run eject

degit has zero extensibility — and that’s by design. It does one thing well. If you need more, you layer other tools on top (e.g., run a script after degit).

npx degit user/template my-app && cd my-app && npm install

sao is highly extensible. Generators can include lifecycle hooks (prepare, post), custom actions, and even call external binaries. You can publish your generator to npm and version it independently.

// sao.js
export default {
  async prepare() {
    // Run before file generation
  },
  async post({ chalk }) {
    console.log(chalk.green('Project ready!'));
  }
};

🧪 Real-World Use Cases

Case 1: Starting a Standard React App

You’re building a marketing site with React and need something that just works.

• ✅ Best choice: create-react-app
• Why? Zero config, official support, and optimized defaults.

npx create-react-app promo-site

Case 2: Bootstrapping a Vite + Vue Project from a Team Template

Your team maintains a private GitHub repo with a pre-configured Vite + Vue 3 setup.

• ✅ Best choice: degit
• Why? You just need the exact files, no questions.

npx degit github:myorg/vue-template my-project

Case 3: Creating a Public CLI Tool Starter Kit

You’re publishing an open-source generator for Node.js CLI tools that supports TypeScript, tests, and bin linking.

• ✅ Best choice: sao
• Why? Users should choose features interactively, and files must be customized per answer.

npx sao sao-cli my-cli-tool
# Prompts: TypeScript? Yes/No
# Prompts: Include tests? Yes/No
# Generates tailored package.json, src/, etc.

⚠️ Important Notes on Current Status

As of 2024, create-react-app is in maintenance mode. The React team recommends using frameworks like Next.js or Remix for new projects, or Vite for simpler setups. While it still works, it won’t receive major new features.

degit and sao remain actively useful for their respective niches. degit is stable and minimal; sao continues to be used by projects like Poi and SAO-based generators in the ecosystem.

📊 Summary Table

💡 Final Guidance

• Need a React app yesterday with no config hassle? → create-react-app (but consider Vite or Next.js for new greenfield projects).
• Just want to copy a folder from GitHub without Git baggage? → degit.
• Building a reusable, interactive project generator for your team or community? → sao.

These tools aren’t competitors — they’re specialists. Pick the one that matches your workflow: opinionated stack, silent copier, or programmable scaffold.
