Fragments Microservice

Back-end cloud-based microservice using AWS cloud technologies.

Overview

Unlike the monolithic architectures, microservice allows each service to be independently scaled to meet demand for the application feature it supports.

Instructions on running the service

1. npm install to install all the dependencies along with node modules folder.

2. After installing all the dependencies, you can run the service with the following methods:

npm start # normal - ready for the production
npm run dev # Run with nodemon and watch src/** folder for any changes
npm run debug # Run with nodemon and node inspector

Run Eslint to make sure the code is following the proper JS coding standards

npm run lint # Run eslint

Notes

◎ ESLint

If you have issues with process.env, add node:true to the env section of your .eslintrc file. Eslint needs to know if you are using node variables like process.

◎ node-inspector

To debug Node, --inspect lets you listen for debugging client. Before running, first make sure you have launch.json. Also ensure you have toggled attach to process in the debugger. If not, do this by cmd + shift + p and search for attach to process and select smart option. References

◎ Curl

You can use this command in terminal to test the service. Make sure you pipe it with jq when required this will make it more readable.

curl localhost:8080 | jq
curl -i localhost:8080 # to get the response headers

◎ Pino-colada

If you want to use simpler than the default (Pino) logger you can use the following minimalistic logger (pino-colada).

1. Comment out the logger in src/logger.js
2. Add the following script to your package.json

"dev": "LOG_LEVEL=debug nodemon ./src/server.js --watch src | pino-colada"
