Pull Request Overview

This pull request refactors migration management by implementing dependency inversion principles and reorganizing the project structure for better maintainability. The changes include moving from function-based migrations to interface-based handlers, restructuring the codebase into distinct packages, and adding support for both MongoDB and MySQL databases.

Key changes:

• Introduces adapter pattern with MigrationHandler interface for better extensibility
• Reorganizes code into src/ directory with separate packages for adapters, DTOs, repositories, and core logic
• Adds comprehensive test coverage with mocks and unit tests
• Removes old global migration approach in favor of dependency injection

The variable tableName is used in the SQL query but the function parameter is name. This will cause a compilation error.

Parameter name has a typo: 'reccord' should be 'record' for consistency with other methods.

Suggested change

	func (erm *MigrationRepositoryMongo) FindOne(reccord *entity.VersionRecord) (*entity.VersionRecord, error) {
	filter := bson.M{"version": reccord.Version, "description": reccord.Description, "type": reccord.Type}
	func (erm *MigrationRepositoryMongo) FindOne(record *entity.VersionRecord) (*entity.VersionRecord, error) {
	filter := bson.M{"version": record.Version, "description": record.Description, "type": record.Type}

The constant AllAvailable is duplicated across multiple files (also in src/pkg/migrate.go). This should be defined in a single location to avoid inconsistency.

Suggested change

	)
	const defaultMigrationsCollection = "migrations"
	const AllAvailable = -1
	"github.com/iamviniciuss/golang-migrations/src/pkg" // import the package where AllAvailable is defined
	)
	const defaultMigrationsCollection = "migrations"

Remove the commented placeholder code as it serves no purpose and clutters the codebase.

Suggested change

//repositoryXXXX: XXXXX

The table schema in CreateCollectionIfNotExists creates a table with 'nome' and 'idade' columns which don't match the migration table structure that should have 'version', 'description', and 'type' columns.

Suggested change

	id INT AUTO_INCREMENT PRIMARY KEY,
	nome VARCHAR(255),
	idade INT
	version BIGINT PRIMARY KEY,
	description VARCHAR(255) NOT NULL,
	type VARCHAR(50) NOT NULL

Comments are in Portuguese. Consider using English for consistency with the rest of the codebase.

The package name 'contact_api' doesn't match the project purpose of golang-migrations. This should be updated to reflect the actual project.
