pgx_migrant
===========
Golang library for migrations and sync interfaces versions of PostgreSQL databases. pgx driver only.
Status
------
It works, but API is unstable. And docs needed.
Usage Example
-------------
```go
package db_sync_helper
import (
"fmt"
"github.com/i-erokhin/pgx_migrant"
"github.com/jackc/pgx"
"giterica.io/project/repo/config"
"giterica.io/project/repo/constants"
)
func DBSyncHelper(c *config.Conf, db *pgx.ConnPool) error {
tx, err := db.Begin()
if err != nil {
return err
}
defer tx.Rollback()
if err = migrate(c, tx); err != nil {
return err
}
return tx.Commit()
}
func migrate(c *config.Conf, tx *pgx.Tx) error {
sm := migrant.SyncMap{
Migration: migrant.MigrationMap{
Path: c.SQlArtifacts.MigrationsPath,
Schema: constants.DBSchema,
},
Interfaces: migrant.InterfacesMap{
Path: c.SQlArtifacts.InterfacesPath,
Schema: constants.DBInterfacesSchema,
},
TemplateData: c,
}
result, err := migrant.SyncDB(tx, sm)
if err != nil {
return err
}
if len(result.Migrations.Files) != 0 {
fmt.Printf("DB state: %d, migrations applied:\n", result.Migrations.Number)
for _, name := range result.Migrations.Files {
fmt.Printf(" %s\n", name)
}
}
if len(result.Interfaces.Files) != 0 {
fmt.Printf("Actual DB interfaces schema: %s, SQL files applied:\n", constants.DBInterfacesSchema)
for _, name := range result.Interfaces.Files {
fmt.Printf(" %s\n", name)
}
}
return nil
}
```
Output:
```
DB state: 2, migrations applied:
01-tables.sql
02-seeds.sql
Actual DB interfaces schema: tabel_interfaces_0, SQL files applied:
01-active_employee.sql
```
