microServiceBaseConsumer

This is dummy but extended example of a NodeJS microservice that can be used as a base for creating new one, more reliable and complete. It was created as resulting from my study about microservices which I did from my short experience creating NodeJS APIs and reading some good tutorials listed bellow.

I hope it can help you learn about microservice and enhance this base.

Considere the microServiceBaseProducer running in other terminal for a complete example.

How it works

This microservices acts like a messaging consumer

Folder structure

• config: contains the configuration files with the parameters used by the microservice (rename de default.json.template to default.json and fullfill it with your own parmeters)
• db: contains the MongoDB connection object
• models: contains all the models responsible for manipulating the data (documents) from/to MongoDB
• services: contains serives that interacts with the external world and other tools (RabbitMQ, fi)
• utils: contains other general purpose utilities like logger object

How to Run

1. have a MongoDB instance running
2. have a RabbitMQ instance running
3. rename config/defaul.json.template to config/default.json
4. fullfill the config/defaul.json with you own parameters
5. install the packages npm i
6. run npm start
7. have a microServiceBaseProducer running and access its endpoints :-)
