build a simple bank service in Go

Create Database Schema

Setup Database & Perform Database Migration on Docker (manually)

1. Pull the database from Docker Hub:

docker pull postgres:15.3-alpine3.18

2. Run the database container:

sudo docker run --name postgres15.3 -p 9876:5432 -e POSTGRES_USER=root -e POSTGRES_PASSWORD=1903 -d postgres:15.3-alpine3.18

3. Login to the database:

sudo docker exec -it postgres15.3 psql -U root

4. Create the simple_bank database:

CREATE DATABASE simple_bank OWNER root;

5. Import the .sql file into the simple_bank database.

Setup Database & Perform Database Migration on Docker (automatically)

You can also perform database migration automatically without doing it manually using Go Database migrations. First, make sure you have pulled the appropriate database image:

docker pull postgres:15.3-alpine3.18

Then, install the required library for Go Database migrations:

go install -tags 'postgres' github.com/golang-migrate/migrate/v4/cmd/migrate@latest

Use the provided Makefile to simplify execution.

Install SQLC and Go Postgres Driver

1. Install SQLC.

2. Install Go Postgres driver for database/sql.

Implement SQLC:

1. Change directory to your project path:

cd /to/your/path/project

2. Initialize SQLC:

sqlc init

3. Set the configuration in sqlc.yaml.

Implement .sql

Implement queries account.sql, entry.sql, transfer.sql .

Implement Unit Tests

1. Install testify for testing.

2. Implement main_test.go to connect to the database.

3. Implement account_test.go, entry_test.go, transfer_test to test the functions.

4. Additionally, you can use random_generate.go to generate random data for testing purposes.
