contract-manager

Prerequisites

Before you begin, ensure you have met the following requirements:

• Node Version Manager (nvm) installed
• pnpm package manager installed

Setup

1. Make sure to fill your .env (see .env.sample):

cat .env.sample

2. Use the required Node.js version using nvm:

nvm use

On Windows, you can use the following command:

nvm use $(Get-Content .nvmrc)

This ensures that the project uses the specified Node.js version.

3. Install project dependencies using pnpm:

pnpm install

This will install all the necessary dependencies for your project.

Usage for development

1. Watch for changes and automatically restart the server in development:

pnpm dev

This command will use nodemon to watch for changes and restart your application when changes are detected.

Generators

1. Generate TypeScript types for Mongoose using mongoose-tsgen:

pnpm gen-types

This command will generate TypeScript types based on your Mongoose models.

2. Generate Swagger API doc with:

pnpm gen-swagger

This command will generate Swagger documentation, accessible at http://localhost:{port}/api-docs/#/

3. Generate Source Code documentation with:

pnpm gen-docs

This command will generate documentation using TypeDoc for the source code and save it in a "docs" folder.

Building the project for production

1. Build the project:

pnpm build

This command will clean the build/ directory and compile your TypeScript code.

2. Start your Node.js application:

pnpm start

This command will start your application using the compiled code.

Docker

1. Clone the repository from GitHub: git clone https://github.com/prometheus-x/contract-manager.git
2. Navigate to the project directory: cd contract-manager
3. Configure the application by setting up the necessary environment variables. You will need to specify database connection details and other relevant settings.
4. Create a docker network using docker network create ptx
5. Start the application: docker-compose up -d
6. If you need to rebuild the image docker-compose build and restart with: docker-compose up -d
7. If you don't want to use the mongodb container from the docker compose you can use the command docker run -d -p your-port:your-port --name contract-manager contract-manager after running docker-compose build

Terraform

1. Install Terraform: Ensure Terraform is installed on your machine.
2. Configure Kubernetes: Ensure you have access to your Kubernetes cluster and kubectl is configured.
3. Initialize Terraform: Run the following commands from the terraform directory.

cd terraform
terraform init

4. Apply the Configuration: Apply the Terraform configuration to create the resources.

terraform apply

5. Retrieve Service IP: After applying the configuration, retrieve the service IP.

terraform output contract_manager_service_ip

• Replace placeholder values in the kubernetes_secret resource with actual values from your .env.
• Ensure the server_port value matches the port used in your application.
• Adjust the host_path in the kubernetes_persistent_volume resource to an appropriate path on your Kubernetes nodes.

Deployment with Helm

1. Install Helm: Ensure Helm is installed on your machine. You can install it following the instructions here.

2. Package the Helm chart:

   helm package ./path/to/contract-manager
   

3. Deploy the Helm chart:

   helm install contract-manager ./path/to/contract-manager
   

4. Verify the deployment:

   kubectl get all -n contract-manager
   

5. Retrieve Service IP:

   kubectl get svc -n contract-manager
   

• Replace placeholder values in the values.yaml file with actual values from your .env.
• Ensure the server_port value matches the port used in your application.
• Configure your MongoDB connection details in the values.yaml file to point to your managed MongoDB instance.

Tests

1. Run tests:

pnpm test

This command will run your tests using Mocha. Make sure your tests are located in ./src/tests/*.test.ts.
