Developing a Rest API with GIN

Tech stack:

• Go
• GIN

$ go get -u github.com/gin-gonic/gin

• GORM:

$ go get -u gorm.io/gorm
$ go get gorm.io/driver/postgres # postgres driver

• Validator: https://pkg.go.dev/gopkg.in/validator.v2

go get gopkg.in/validator.v2

• Test: github.com/stretchr/testify

go get github.com/stretchr/testify

• To execute just one test

go test -run TEST_name

• Postgres
• PGAdmin
• docker
  • Find Postgres IP:

  $ docker inspect CONTAINER_ID | grep IPAdd

Go mod init:

• go mod init github.com/luciormoraes/go-rest-api
• go mod init go-rest-api

Day 24/100: Developing a Rest API with GIN

• Installing gin
• creating a gin server / first Endpoint(GET)
• creating packages: routes/ controllers/ models

Day 25/100: Developing a Rest API with GIN

• Installing GORM
• Change controller to create students / new endpoint
• using autoMigrate from gorm: Struct Student as gorm.Model

Day 27/100: Developing a Rest API with GIN

• return all students from DB
• new endpoints: SearchStudentByID, DeleteStudent, EditStudent, SearchStudentByIRD

Day 30/100: Developing a Rest API with GIN

• writing validations: installing Validator.v2

Day 31/100: Developing a Rest API with GIN

• applying validations model / controller: not null strings, length, just numeric values
• creating tests: check status code
• adding Testify to assert

Day 32/100: Developing a Rest API with GIN

• testing endpoints
• creating student mock, delete student mock

Day 36/100: Developing a Rest API with GIN

• rendering html pages with gin: index and 404
• register a path for static files
