▶  New Project
  Module
  Endpoint
  DB Service

Enter Project Name: yourprojectname

Modules

To create a new module with crud flow: please use snake_case when the module name consist of two or more words

  New Project
▶  Module
  Endpoint
  DB Service

Enter Module Name: your_module_name

Endpoint

To create a new db service client with Mysql, Gorm or Prisma:

  New Project
  Module
  Endpoint
▶  DB Service

Mysql - to learn more visit (https://github.com/go-sql-driver/mysql)

Enter DB(mysql, gorm) Name: mysql

Gorm - to learn more visit (https://github.com/jinzhu/gorm)

Enter DB(mysql, gorm) Name: gorm

This will generate a database connection in data/db.go


For Mysql and Gorm import the service in your repository like for example:

db "yourProjectName/data"

Example for Mysql:

// Insert new tasks
res, err := db.Client().Exec("INSERT INTO tasks VALUES(DEFAULT, 'Title', 'Desc')")
if err != nil {
  fmt.Println("ERROR: ", err)
}
fmt.Println(res)

  Description: "This is a description",
})

Async

How to use async:

package main

import async "yourProjectName/helpers"

//This functions wait 3 seconds to return 1
func DoneAsync() int {
	fmt.Println("Warming up ...")
	time.Sleep(3 * time.Second)
	fmt.Println("Done ...")
	return 1
}

func main() {
	fmt.Println("Let's start ...")

  //Here you call the function as async function
	future := async.Exec(func() interface{} {
		return DoneAsync()//The function that will await
	}).Await()

	fmt.Println("Done is running ...")
	fmt.Println(future)
}

Swagger

Build your application and after that, go to http://localhost:5000/swagger/index.html , you to see your Swagger UI.

When you create a new module swagger will be added automatically then you only need to modified what you need, but remember each time you modified swagger use the next command

swag init
