Cryptallion Backend: Getting Started
This guide outlines the steps to set up and run the Cryptallion backend project effectively.
Prerequisites:
- Node.js (version 14 or later): https://nodejs.org/en
- npm (Node Package Manager) or yarn (usually included with Node.js installation)
- MongoDB (version 4 or later): https://www.mongodb.com/try/download/community
Installation:
-
Clone the Repository:
git clone https://github.com/your-username/cryptallion-backend.git
-
Navigate to the Project Directory:
cd cryptallion-backend
-
Install Dependencies:
npm install # or yarn install
Environment Variables:
-
Create a file named
.env
in the project's root directory. This file should not be committed to version control. -
Fill the
.env
file with the following variables, replacing the placeholders with your actual values:# Database DB_HOST=localhost # Your MongoDB host address DB_PORT=27017 # MongoDB port (default: 27017) DB_DATABASE=cryptallion # Your database name DB_USERNAME=your_username # Your MongoDB username (if required) DB_PASSWORD=your_password # Your MongoDB password (if required) # Server PORT=5000 # Port on which the server will run (default: 5000) # Node Environment NODE_ENV=development # Set to 'production' for deployment (default: development) # Redis Server (optional) REDIS_URL=redis.cloud.redislabs.com # Your Redis server URL (if using) REDIS_PASSWORD=your_password # Your Redis password (if using) REDIS_PORT=19094 # Your Redis port (if using) # JWT Secret (for authentication) JWT_SECRET=your_secret_key # A strong and unique secret key # File Storage Path (optional) FILES_PATH=/tmp/cryptallion # Path for storing uploaded files
-
Important: Consider using a secure environment variable management tool like dotenv for managing sensitive information like passwords.
Running the Development Server:
-
Start the MongoDB instance:
Follow MongoDB's installation instructions to set up your MongoDB server and create the desired database (
cryptallion
in this case). -
Start the Server:
npm run start-server # or yarn start-server
This will start the backend server, typically listening on port
5000
(as defined in.env
). You can access the API athttp://localhost:5000/
in your browser (depending on your API endpoints).
Deployment (Optional):
-
Set
NODE_ENV=production
:In your deployment environment, ensure the
NODE_ENV
variable is set toproduction
. This might involve environment variable configuration steps specific to your deployment platform. -
Build for Production (Optional):
Some projects benefit from creating a production build to optimize the code for deployment. Consult your project's build instructions if applicable.
-
Start the Server:
The command to start the server in production mode might differ. Refer to your project's specific instructions.
Available Scripts:
npm lint
oryarn lint
: Runs the linter to check for code style and potential errors.npm check-lint
oryarn check-lint
: Checks for lint errors in specifically numbered files (e.g.,1.js
,2.js
).npm start-server
oryarn start-server
: Starts the backend server in development mode.npm start-worker
oryarn start-worker
: Starts any background workers for tasks like image processing (if applicable).npm dev
oryarn dev
: Starts the server and any workers for development.npm test
oryarn test
: Runs the test suite to ensure code quality.
Key Dependencies:
- Express: The web framework used for building the server.
- MongoDB: The NoSQL database used for data storage.
- Redis: An in-memory data store used for caching and potentially for task queues.
- Bcrypt: A password-hashing library for secure authentication.
- JSON Web Tokens (JWT): A library for creating and verifying authentication tokens.
- Image-Thumbnail: A library for generating image thumbnails (if applicable).
- Bull: A library for handling background job queues (if applicable).
By following these steps and customizing them as needed, you should be able to successfully set up and run the Cryptallion backend project.
