📌 How to Use @compodoc/compodoc?

✅ Install It

npm install --save-dev @compodoc/compodoc

✅ Generate Documentation

Run the following command to generate documentation:

npx compodoc -p src/tsconfig.app.json -d docs

or

npx compodoc -p tsconfig.json -d docs

• -p → Path to tsconfig.app.json

• -d → Output directory (e.g., docs/)

✅ Serve Documentation Locally

To open the documentation in a browser:

npx compodoc -s

If Error - 

[15:10:45] No configuration file found, switching to CLI flags.
[15:10:45] ./documentation/ folder doesn't exist

mkdir documentation

Alternative depedency instead of Compodoc depedency for angular or typescript project

Yes! While Compodoc is the most popular tool for generating documentation for Angular projects, Angular does not officially recommend any specific documentation tool. However, here are some alternative tools that you can use:

---

✅ 1. TypeDoc (Officially Recommended for TypeScript)

TypeDoc is the officially recommended documentation generator for TypeScript projects. Since Angular is built with TypeScript, this can be a good alternative.

📌 How to Install TypeDoc?

npm install --save-dev typedoc

📌 How to Generate Documentation?

npx typedoc --out docs src

Pros:

✅ Recommended by TypeScript maintainers.
✅ Works well for TypeScript-based Angular projects.
✅ Simple and fast.

Cons:

❌ Lacks Angular-specific support (no component/module diagrams like Compodoc).

---

✅ 2. Angular CLI ng doc (For Official Angular Docs)

If you only need to refer to official Angular documentation, you can use the Angular CLI:

ng doc component

This opens the official Angular documentation for the queried keyword. However, it does not generate documentation for your project.

---

✅ 3. Dgeni (Used by Angular Team)

Dgeni is a documentation generator used internally by the Angular team to generate their official docs.

📌 How to Install Dgeni?

npm install --save-dev dgeni dgeni-packages

📌 How to Configure?

You'll need a configuration script to process your files. Example:

const Dgeni = require('dgeni');
const packages = require('dgeni-packages');

const dgeni = new Dgeni([packages.basePackage]);
dgeni.generate().then(docs => {
  console.log('Generated ' + docs.length + ' docs');
});

Pros:

✅ Used by the Angular team for their documentation.
✅ Highly customizable.

Cons:

❌ Requires manual configuration.
❌ Less beginner-friendly than Compodoc.

🚀 Which One Should You Choose?

Alternative	Best For	Pros	Cons
Compodoc (Recommended)	Angular projects	Easy to use, supports Angular concepts	May have issues with large projects
TypeDoc	TypeScript documentation	Officially recommended for TypeScript	Lacks Angular-specific support
Angular CLI ng doc	Quick reference	Opens official Angular docs	Doesn't generate project documentation
Dgeni	Advanced customization	Used by Angular team, highly flexible	Requires configuration

---

🎯 My Recommendation

• If you want Angular-specific documentation, stick with Compodoc.

• If you just need TypeScript-based documentation, use TypeDoc.

• If you need full customization, Dgeni is an option (but complex).
