Zeroslope GoLang

This is the zeroslope microservice architecture using GO. Average response times are around ~2ms for api calls that use a database, and non-database api calls ~28μs. Memory footprint seems to be around 9.9mb of ram allocated to the go process when running the most expensive call.

Recently updated to reflect changes in GO 1.13.X.

Technologies

Here is a list of the technologies used in this project:

• We use MODULES for package management.
• We use SWAG for swagger generation.
• We use DLV for Debugging in VSCODE
• We use GIN for http routing.
• We use VEGETA for load testing.
• We use GORM for our ORM layer.
• We use PG for postgres database access.

Endpoints

Here is an overall layout of what endpoints come with this architecture:

Method	Route	Description
N/A	/swagger/index.html	Swagger UI
GET	/health/	Health check.
POST	/auth/login	Creates a JWT token for access.
GET	/sample	Gets a list of records.
GET	/sample/:id	Gets a record by id.
POST	/sample/	Creates a record.
PUT	/sample/	Updates a record.
DELETE	/sample/:id	Deletes a record.

Development

Currently I write my golang in VSCODE and use the following commands:

Installing dependencies

go mod vendor

Updating swagger docs

cd src; swag init; cd ..

Running locally

go run main.go

Visit: http://localhost:8080/swagger/index.html

Setting up postgres in docker

docker run --name pgdb -p 5432:5432 -e POSTGRES_PASSWORD=P4ssw0rd! -e POSTGRES_DB=zeroslope -d postgres
