This template is intended to be used as single service in a REST multi-service application using Cloud Pub/Sub asmessage broker

use in local with Skaffold and in cloud with GKE

To know more about how to implement GKE and run with Skaffold please refer to this folder:

./infra

The application uses express as framework and is configured with the following features:

• MySQL ready to go configuration with mysql2
• CORS feature enabled
• RBAC logic to authorize people with specific roles to use the endpoints.
• Passport logic to add an authentication layer if neeeded.
• Sparkpost email service support with sparkpost.
• Error Handling errors custom middleware and helpers globally configured
• Multer File uploading configured to use in routes as middleware
• Google Cloud Storage middleware configured to use Google Cloud Storage as upload bucket
• Google Cloud Pub/Sub pub/sub support for event driven events added
• Axios globally configured in./src/utils/api.utils.js
• Swagger documentation reachable athttp://localhost:3000/api/v1/docs
• Jest Testing tool support
• Logger Logging support with Winston
• Docker ready configuration with multi-stage option
• Terraform ready configuration to instantiate infrastracture in GCP
• Agenda ready to emit events through agenda jobs
• Best practices in naming files

• For more information about the k8s configuration please check the README file
• k8s - folder contains all production kubernetes manifests
• k8s-dev - folder contains all development kubernetes manifests to run with skaffold
• scripts - older contains all script related to the creation of a cluster or running skaffold or secretcreation

src/

• api/ - containing all api logic with model, services, controller and routes
• bin/ - server configuration folder
• config/ - this folder contains all the configs file (database, passport, etc...)
• constants/ - this folder contains all the global constants
• logs/ - the logger file will be stored here
• helpers/ - some helpers func i.e. an error helper that returns json everytime an error comes in
• middlewares/ - here you can find all the custom middlewares
• services/ - here we store all the services; i.e. here we define methods to manipulate a db model entity
• tests/ - here we store all the jest test
• utils/ - containing some utils function to be reused in the code (i.e. axios global configuration)

Copy the .env.example to .env. Be sure to fill all the global variables. Alternatively you can use the scriptgenerate-env.sh in the scripts folder. This script will generate a.env.test.local and you can copy this file to .env

cp env.example .env

Then replace:

1. MONGO_URI string with your Mongo connection
   1. MONGO_URI_TEST string with your Mongo Test connection
2. MYSQL_HOST_STAGE string with your mysql host name

6. SENDGRID_SENDER_EMAIL with yours

In order to Google Cloud Storage works follow instructions located in./src/config/gcloud/README.md

To get started with this repo npm install in the root folder

npm install

To getting started with a dev environment. Here we use nodemon and babel-node to restart the server asa we changesomething

npm run start:dev

To compile the code and create a production build

npm run compile

This command will create a build in the root directory

To start with a production ready build you can run this command

# This set the NODE_ENV to production, npm-run-all, create a build and run the server commandnpm run start

If you have a build and you want to node the build you can run

# This command launch the node instance inside the ./build/bin/servernpm run server

If you use Docker and wanna dockerize the app you can run the command

docker build -t<dockerhubusername>/<docker-image-name>:<tag>.

then

docker run --name<docker-process-name> -d - p 3000:3000<dockerhubusername>/<docker-image-name>:<tag>
