How to Setup CrawlBot on Local PC (Step-by-Step Guide)

If you want to test and develop CrawlBot locally before deploying it to a live server, this guide will walk you through the complete setup process on your PC. This tutorial is beginner-friendly and works for Windows, macOS, and Linux users.

Step 1: Install Required Software

1. Install Node.js

CrawlBot runs on Node.js, so you must install it first.

1. Go to the official Node.js website.
2. Download the LTS (Long Term Support) version.
3. Install it using default settings.
4. Verify installation by running:

node -v
npm -v

If version numbers appear, Node.js is installed correctly.

2. Install Git

Git is required to clone the CrawlBot project from a repository.

1. Download Git from the official website.
2. Install with default settings.
3. Verify installation:

git --version

Step 2: Download CrawlBot

Open Command Prompt or Terminal and run:

git clone https://github.com/your-repo/crawlbot.git
cd crawlbot

This will download the project and move you into the project directory.

Step 3: Install Project Dependencies

Inside the project folder, run:

npm install

This command installs all required packages listed in the package.json file.

Step 4: Configure Environment Variables

Create a .env file in the root directory and add necessary configuration values:

PORT=3000
API_KEY=your_api_key
DATABASE_URL=your_database_url

If the project includes a .env.example file, copy it and rename it to .env, then update the values accordingly.

Step 5: Setup Database (If Required)

If CrawlBot requires a database:

• Install MongoDB locally and start the service.
• Or use a cloud database like MongoDB Atlas.
• Update your .env file with the database connection string.

Step 6: Run CrawlBot

Start the application using:

npm start

Or for development mode:

npm run dev

If successful, you should see something like:

Server running on http://localhost:3000

Step 7: Test in Browser

Open your browser and visit:

http://localhost:3000

If the page loads correctly, your CrawlBot is running successfully on your local PC.

Optional: Use Nodemon for Auto Restart

Install Nodemon globally:

npm install -g nodemon

Run the application:

nodemon index.js

This will automatically restart the server whenever you make changes.

Common Errors & Fixes

Port Already in Use

Change the PORT number in your .env file.

Module Not Found

Run:

npm install

Database Connection Failed

Make sure your database service is running and your connection string is correct.

Conclusion

Setting up CrawlBot on your local PC allows you to safely test features, debug errors, and develop improvements before deploying to a live server. Once everything works properly on localhost, you can deploy it to a VPS or cloud hosting platform.
