component

ExampleComponent shows how Component() is used in a bootstrap registration chain. It reads PostgreSQL connection parameters from env during Init():

db.host, db.port, db.name, db.schema, db.username, db.password

Open verifies connectivity with an eager ping — if the database is unreachable, Init() returns a non-nil error and bootstrap aborts startup.

bootstrap.New().
    Add(envComp.Component(...)).
    Add(logComp.Component()).
    Add(dbComp.Component()).
    PreReady(func() error {
        _, err := dbsqlx.Default().Exec(schemaSQL)
        return err
    }).
    Run()

package main

import (
	"fmt"

	dbComp "github.com/phcp-tech/common-library-golang/dbsqlx/postgres/component"
)

func main() {
	c := dbComp.Component()
	fmt.Println(c != nil)
}

Output:
true
