NodeJS Microservice Project#

This guide provides a step-by-step example of creating a basic NodeJS microservice project. It includes the necessary configurations for platform, runtime, language, and dependencies.

type: Project
kind: Application
name: Example.NodeJSMicroservice
metadata:
  tags: [backend, nodejs]
specifications:
  name: NodeJSMicroservice
  platform:
    type: NodeJS
    version: 14
  runtime:
    type: NodeJS
    version: 14
  language:
    type: JavaScript
    version: ES6
  project_type: webapi
  package: com.example.nodejsmicroservice
  path: /services/nodejsmicroservice
  configuration:
    layers:
    - name: Controllers
      path: controllers
      package: com.example.nodejsmicroservice.controllers
    - name: Services
      path: services
      package: com.example.nodejsmicroservice.services
    dependencies:
    - name: express
      version: 4.17.1
    - name: mongoose
      version: 5.10.9

Key Sections Explained#

  • type: The type of the project. Always set to Project.
  • kind: The kind of the project. Should be Application.
  • name: A unique identifier for your project.
  • metadata: Additional information about your project. Here, tags like backend and nodejs are used.
  • specifications: Detailed configuration of your project.
    • name: The name of the project instance.
    • platform: Specifies the platform type and version. Here, NodeJS version 14 is used.
    • runtime: Specifies the runtime environment. Here, NodeJS version 14 is used.
    • language: Specifies the programming language and version. Here, JavaScript version ES6 is used.
    • project_type: The type of the project. Here, it is a webapi.
    • package: The package or namespace for the project.
    • path: The relative path where the project will be located.
    • configuration: Configuration details for the project.
      • layers: Defines the directory and package structure.
      • dependencies: Lists the external dependencies, such as NPM packages.

Detailed Steps#

  1. Set Project Type and Kind:

    • Ensure type is Project and kind is Application.

  2. Provide Unique Name:

    • Set a unique name for the project under name (e.g., Example.NodeJSMicroservice).

  3. Add Metadata Tags:

    • Use metadata to add tags like backend and nodejs.

  4. Define Specifications:

    • name: The name of the project instance (e.g., NodeJSMicroservice).
    • platform: Specify the platform type and version (e.g., NodeJS version 14).
    • runtime: Specify the runtime environment (e.g., NodeJS version 14).
    • language: Specify the programming language and version (e.g., JavaScript version ES6).
    • project_type: Define the type of the project (e.g., webapi).
    • package: Define the package or namespace for the project (e.g., com.example.nodejsmicroservice).
    • path: Specify the relative path where the project will be located (e.g., /services/nodejsmicroservice).

  5. Configure Layers:

    • Define layers for organizing the project's directory and package structure.
    • Example layers:
      • Controllers: Manages HTTP requests.
      • Services: Contains business logic.

  6. Specify Dependencies:

    • List external dependencies using NPM packages.
    • Example dependencies:
      • express version 4.17.1
      • mongoose version 5.10.9

This example shows how to configure a basic NodeJS microservice project with the necessary settings for platform, runtime, language, layers, and dependencies. Follow these steps and use the YAML structure provided to create a fully functional NodeJS microservice project.

By following this guide, you will have a clear understanding of how to set up a basic NodeJS microservice project with the required configurations. This serves as a foundation for more advanced configurations and customizations.
