helixml / demo-recipes

Prerequisites

Before deploying the helixml/demo-recipes project, ensure you have the following tools installed and configured properly:

  • Node.js (>= 14.x)
  • npm (Node Package Manager)
  • Docker
  • TypeScript
  • A cloud service provider account (AWS, Azure, GCP, etc.) if deploying to the cloud

Step 1: Building the Project

First, ensure that the project is built correctly. Navigate to the project directory in the terminal and run:

npm install
npm run build

This will install all the required dependencies and compile the TypeScript code into JavaScript.

Step 2: Setting Environment Variables

Set the necessary environment variables required for a production environment. Create a .env file in the root of the project with the following structure:

NODE_ENV=production
API_URL=https://api.yourservice.com
DATABASE_URI=mongodb://user:password@host:port/database

Ensure that you replace the example values with actual service configurations.

Step 3: Dockerizing the Application

To deploy the project using Docker, create a Dockerfile in the root directory of the project if it’s not already present. A basic Dockerfile for this project might look like this:

# Use the official Node.js image.
FROM node:14

# Set the working directory.
WORKDIR /usr/src/app

# Copy package.json and package-lock.json.
COPY package*.json ./

# Install dependencies.
RUN npm install --production

# Copy the built application.
COPY dist ./dist

# Expose the port the app runs on.
EXPOSE 3000

# Command to run the application.
CMD ["node", "dist/index.js"]

Step 4: Building the Docker Image

To build the Docker image for your application, run the following command:

docker build -t your-application-name .

This command compiles the Dockerfile instructions and produces an image tagged with your-application-name.

Step 5: Running the Docker Container

You can run the Docker container using the following command:

docker run -d -p 3000:3000 --env-file .env your-application-name

This will start a detached container and map port 3000 on your host to port 3000 in the container, making the application accessible via http://localhost:3000.

Step 6: Setting Up the Database

If using a database like MongoDB, ensure the instance is running and accessible from your application’s environment. Update the DATABASE_URI in the .env file as needed.

Step 7: Deploying to a Cloud Provider

If deploying to a cloud provider, follow the specific guidelines for deploying Docker containers. For example, with AWS Elastic Beanstalk, you would:

  1. Create a new Elastic Beanstalk Application.
  2. Choose a Docker platform and upload the Docker image or Dockerfile.
  3. Configure your application environment with the required instance type and scaling settings.
  4. Set the environment variables from the .env file in the Elastic Beanstalk configuration.
  5. Deploy the application.

For Azure, you could use Azure Web Apps for Containers with a similar process or use Google Cloud Run for deploying containers in GCP.

Step 8: Monitoring and Logging

Set up monitoring and logging to keep an eye on application performance and errors. You could integrate services like AWS CloudWatch, Azure Monitor, or Google Cloud Operations Suite.

Conclusion

This guide outlines the essential steps for deploying the helixml/demo-recipes project into a production environment. Ensure all configurations align with your organization’s security and operational practices.
