How to Setup apiDoc? (An Ultimate Guide)

Setting up apiDoc involves a few steps, including installation, annotating your API code, and generating documentation. Here's a step-by-step guide with an example:

Step 1. Install apidoc on Windows 10

To install ApiDoc on Windows 10, you'll need to use the Node Package Manager (npm), which comes with Node.js. Here are the steps to install ApiDoc on Windows 10:

Install Node.js: If you haven't already, download and install Node.js from the official website: Node.js Download
Open Command Prompt or PowerShell: Once Node.js is installed, open either Command Prompt or PowerShell on your Windows machine.
Install ApiDoc: In the command line interface, use the following command to install ApiDoc globally:

npm install -g apidoc

This command installs ApiDoc globally, allowing you to use it from any directory on your machine.

4. Verify Installation: After the installation is complete, you can verify it by checking the installed version:

apidoc -v

This command should display the installed ApiDoc version.

Step 2: Create a Node.js Project

Create a new directory for your Node.js project and navigate into it using the command line:

mkdir my-api-project
cd my-api-project

Step 3: Initialize a Node.js Project

Run the following command to initialize a new Node.js project. This will create a package.json file:

npm init -y

Step 4: Install apiDoc

Install apiDoc as a development dependency:

npm install apidoc --save-dev

Step 5: Annotate Your API Code

Create a file (e.g., app.js) with a simple Express.js API and add apiDoc annotations:

// app.js/**
 * @api {get} /api/greet Get a Greeting
 * @apiName GetGreeting
 * @apiGroup Greetings
 *
 * @apiSuccess {String} message A welcome greeting.
 */const express = require('express');
const app = express();
const port = 3000;
app.get('/api/greet', (req, res) => {
  res.json({ message: 'Welcome to the API!' });
});
app.listen(port, () => {console.log(`Server is running at http://localhost:${port}`);
});

Step 6: Configure apiDoc

Create a apidoc.json configuration file in your project's root directory:

// apidoc.json{"name": "My API Documentation","version": "1.0.0","description": "Documentation for my API","title": "My API Docs","url": "http://localhost:3000"}

Step 7: Generate API Documentation

Run the following command to generate API documentation based on your annotations:

npx apidoc -i . -o docs

This command tells apiDoc to look for annotated source code files in the current directory (-i .) and output the generated documentation to the docs/ directory (-o docs).

Step 8: View the Documentation

Open the generated documentation in your browser.
