We are using the github [issue tracker](https://github.com/vardius/gocontainer/issues) to manage them.
## π Documentation
For __examples__ **visit [godoc#pkg-examples](http://godoc.org/github.com/vardius/gocontainer#pkg-examples)**
For **GoDoc** reference, **visit [pkg.go.dev](https://pkg.go.dev/github.com/vardius/gocontainer)**
[MustInvokeMany](https://godoc.org/github.com/vardius/gocontainer#example-package--MustInvokeMany)
π HOW TO USE
==================================================
First file `main.go` simply gets the repository from the container and prints it
we use **MustInvoke** method to simply present the way where we keep type safety
```go
package main
import (
"github.com/vardius/gocontainer/example/repository"
"github.com/vardius/gocontainer"
)
func main() {
gocontainer.MustInvoke("repository.mysql", func(r Repository) {
fmt.Println(r)
})
}
```
Our database implementation uses `init()` function to register db service
```go
package database
import (
"fmt"
"database/sql"
"github.com/vardius/gocontainer"
)
func NewDatabase() *sql.DB {
db, _ := sql.Open("mysql", "dsn")
return db
}
func init() {
db := gocontainer.MustGet("db")
gocontainer.Register("db", NewDatabase())
}
```
Our repository accesses earlier on registered db service
and following the same patter uses `init()` function to register repository service within container
```go
package repository
import (
"fmt"
"database/sql"
"github.com/vardius/gocontainer"
_ "github.com/vardius/gocontainer/example/database"
)
type Repository interface {}
func NewRepository(db *sql.DB) Repository {
return &mysqlRepository{db}
}
type mysqlRepository struct {
db *sql.DB
}
func init() {
db := gocontainer.MustGet("db")
gocontainer.Register("repository.mysql", NewRepository(db.(*sql.DB)))
}
```
You can disable global container instance by setting `gocontainer.GlobalContainer` to `nil`.
This package allows you to create many containers.
```go
package main
import (
"github.com/vardius/gocontainer/example/repository"
"github.com/vardius/gocontainer"
)
func main() {
// disable global container instance
gocontainer.GlobalContainer = nil
mycontainer := gocontainer.New()
mycontainer.Register("test", 1)
}
```
