Setting Up MongoDB for Local Development

This guide explains how to install MongoDB, set it up, and run it locally for your development environment.

Prerequisites

• macOS: Homebrew installed
• Windows: Chocolatey or download from MongoDB website
• Linux: Package manager (apt, yum, etc.)

Installation

macOS

1. Install MongoDB using Homebrew

   Open your terminal and run the following commands to install MongoDB:

   brew tap mongodb/brew
   brew install mongodb-community
   brew install mongosh

2. Verify the Installation

   Check if MongoDB has been installed correctly:

   mongod --version

Windows

1. Install MongoDB using Chocolatey

   Open PowerShell as Administrator and run the following command:

   choco install mongodb

   Alternatively, you can download MongoDB from the MongoDB Download Center and follow the installation instructions.

2. Verify the Installation

   Check if MongoDB has been installed correctly:

   mongod --version

Linux

1. Install MongoDB on Ubuntu

   Follow these commands to install MongoDB on Ubuntu:

   sudo apt update
   sudo apt install -y mongodb

2. Start MongoDB

   Start the MongoDB service:

   sudo systemctl start mongodb

3. Verify the Installation

   Check if MongoDB has been installed and is running:

   mongod --version

Setup

1. Create Data Directory

   MongoDB requires a data directory to store its data. Create this directory in your home directory:

   mkdir -p ~/data/db

2. Set Permissions

   Ensure that you have the necessary permissions for the data directory:

   sudo chown -R `id -un` ~/data/db

3. Create a Configuration File

   Create a MongoDB configuration file (e.g., mongodb.conf) in your home directory with the following content:

   storage:
     dbPath: /Users/your_username/data/db
   net:
     bindIp: 127.0.0.1
     port: 27017
   

   Replace your_username with your actual username.

Running MongoDB Locally

1. Start MongoDB

   Start the MongoDB server using the configuration file:

   mongod --config ~/mongodb.conf

2. Verify MongoDB is Running

   Open another terminal window and start the MongoDB shell:

   mongosh

   You should see the MongoDB shell prompt (>).

Importing Data into MongoDB

To import your jobs data into MongoDB for testing, follow these steps:

1. Save Your Data to a JSON File

   Save your job data to a file named jobs.json. Ensure the file is properly formatted as a JSON array.

   [
     {
       "_id": { "$oid": "667444b7c7529daf4422f3c8" },
       "id": { "$numberInt": "3" },
       "title": "Data Scientist",
       "company": "Data Wizards Corp",
       "description": "We are hiring a Data Scientist to help us extract insights from large datasets...",
       "date_created": "2024-05-20T09:00:00Z",
       "date_updated": "2024-05-20T09:00:00Z",
       "location": "San Francisco, CA, USA",
       "type": "Full-time",
       "salary": "95,000 - 120,000 USD",
       "requirements": ["Master's degree in Data Science, Statistics, or related field", "3+ years of experience in data analysis", "Proficiency in Python, R, and SQL"],
       "responsibilities": ["Analyze large datasets to extract actionable insights", "Develop predictive models", "Collaborate with cross-functional teams"],
       "benefits": ["Health insurance", "Stock options", "Gym membership"],
       "application_deadline": "2024-08-01T23:59:59Z",
       "contact_information": { "email": "jobs@datawizards.com", "phone": "456-789-1230" },
       "job_category": "Data Science",
       "experience_level": "Mid-level",
       "education": "Master's degree",
       "company_logo": "https://example.com/logos/data_wizards_logo.png",
       "remote": true,
       "how_to_apply": "Send your resume to jobs@datawizards.com"
     }
     // Add more job objects as needed
   ]

   Or download this more comprehensive file:

   jobs.json

2. Import the Data

   Use the mongoimport tool to import the data into your MongoDB database:

   mongoimport --db testDB --collection jobs --file path/to/jobs.json --jsonArray
   

   Replace path/to/jobs.json with the actual path to your jobs.json file.

3. Verify the Import

   Open the MongoDB shell:

   mongosh
   

   Switch to your database and check the imported data:

   use testDB
   db.jobs.find().pretty()

Environment Configuration

To configure your application to use different MongoDB instances for development and production, use environment variables.

1. Create a .env File

   Create a .env file in the root of your project with the following content:

   MONGODB_LOCAL_URI=mongodb://localhost:27017/testDB
   

By following these steps, you can set up MongoDB for local development, import data for testing, and configure your application to use different MongoDB instances for development and production.
