Advanced Backend Development with Go

Learn Go’s syntax, types, functions, structs, interfaces, error handling, and modules while setting up the course project. You’ll be able to write and organize basic Go code and build a foundation for the API.

• Set Up the Go Toolchain and Course Module

  Initialize a Go module, configure an editor with Go support, and verify the toolchain with go version, gofmt, and go test.

• Use Go Declarations, Types, and Zero Values

  Implement a small package that uses Go declarations, built-in types, conversions, and zero values idiomatically.

• Model Domain Data with Structs and Methods

  Define domain structs and methods that encapsulate state and behavior in a cohesive Go package.

• Compose Interfaces and Handle Errors Explicitly

  Implement an interface-based workflow that returns and handles contextual errors without relying on exceptions.

• Project: Build a Tested Go Domain Package

  Build and test a reusable domain package with structs, methods, interfaces, and explicit error handling.

• Capstone: Create the Course API Foundation

  Create a version-controlled Go API starter with a runnable HTTP endpoint, organized packages, and passing tests.

Apply Go conventions and core backend patterns, including context, concurrency, configuration, and structured error handling. You’ll shape the project into a maintainable service ready to handle requests.

• Go Service Toolchain and Workspace Setup

  Configure a Go development workspace with gofmt, go test, and golangci-lint for the module.

• Idiomatic Service Structure and Structured Errors

  Organize a backend service into cohesive Go packages and return errors that preserve context and support inspection.

• Context Propagation Across Request Lifecycles

  Propagate context through handlers and service dependencies to enforce cancellation and deadlines.

• Reliable Configuration and Structured Logging

  Load and validate service configuration at startup and emit structured logs with request-relevant fields.

• Project: Build a Concurrent Request-Processing Service

  Build a runnable Go service that processes requests with bounded concurrency, context cancellation, validated configuration, and structured errors.

• Graceful Shutdown and Service-Level Testing

  Implement graceful shutdown and integration tests that verify request handling, cancellation, and error responses.

• Capstone: Harden and Deliver an Idiomatic Go Backend

  Deliver a production-ready backend service that integrates idiomatic structure, configuration, context propagation, concurrency, structured errors, and graceful shutdown.

Build REST endpoints with Go’s net/http package, using request validation, middleware, and consistent response patterns. You’ll create the first working API features for the ongoing project.

• Set Up the Go HTTP API Development Environment

  Configure a Go module, API test workflow, and HTTP client for developing and exercising the project API.

• Build HTTP Routes and Handlers with net/http

  Implement method-aware routes and handlers that translate HTTP requests into application operations.

• Validate Requests and Standardize JSON Responses

  Apply request validation and return consistent JSON success and error responses with appropriate status codes.

• Compose Middleware for Cross-Cutting HTTP Concerns

  Add reusable middleware for request IDs, structured logging, and panic recovery to the API handler chain.

• Project: Implement the First API Features

  Build and test a cohesive set of project endpoints using routing, validation, response patterns, and middleware.

• Capstone: Deliver a Reliable HTTP API

  Integrate and verify an end-to-end API feature with consistent errors, middleware, and HTTP-level tests.

Connect the service to PostgreSQL using Go’s database/sql package, and implement data access, schema changes, and transaction handling. You’ll persist project data and handle common database failures.

• Set Up PostgreSQL and Go Database Tooling

  Configure a local PostgreSQL environment and Go project with a database/sql-compatible driver.

• Design PostgreSQL Schemas and Apply Versioned Migrations

  Create a relational schema and manage its evolution with versioned migrations.

• Connect Go Services with database/sql and Configure Connection Pools

  Establish and configure a database/sql connection pool using application settings and context-aware operations.

• Implement Safe Repository Operations and Handle Database Errors

  Build parameterized repository methods for CRUD operations and map common PostgreSQL failures to application errors.

• Use Transactions to Preserve Data Integrity

  Implement multi-step database operations with transactions, rollback behavior, and constraint-aware error handling.

• Capstone Project: Persist Project Data in a Go Service

  Build and test a Go service persistence layer that uses migrations, repositories, connection pooling, and transactions.

Add automated tests and strengthen the API with authentication, authorization, input validation, and secure configuration practices. Document its endpoints with OpenAPI so the finished service is safer and easier to use.

• Set Up Go API Testing and Security Tooling

  Configure Go test tooling, a test database, and security analysis tools for the existing API.

• Test API Behavior with Unit, Integration, and HTTP Tests

  Implement tests that verify handler behavior, database interactions, and API error responses.

• Implement Authentication and Authorization

  Protect API endpoints with authenticated identity and role- or policy-based access checks.

• Build a Validated API with Secure Configuration

  Create a tested API feature that validates inputs and loads secrets and security settings safely.

• Document and Validate the API with OpenAPI

  Write an OpenAPI specification that documents endpoint schemas, security requirements, and error responses.

• Capstone: Deliver a Tested, Secured, Documented Go API

  Integrate automated tests, authentication, authorization, input validation, secure configuration, and OpenAPI documentation into a deployable service.

Package the service with Docker and deploy it on AWS using Amazon ECS with Fargate, connecting it to Amazon RDS for PostgreSQL and using AWS IAM and CloudWatch for operational needs. You’ll publish and verify the live API, completing the course project.

• Set Up the AWS Deployment Toolchain

  Configure Docker, the AWS CLI, Terraform, and secure AWS account access for the Go API deployment.

• Build a Production-Ready Go API Container

  Package the Go API in a secure, minimal Docker image and verify it locally with its required configuration.

• Provision AWS Networking, IAM, and PostgreSQL

  Define the network, least-privilege IAM roles, and private RDS for PostgreSQL resources required by the API.

• Publish the Container and Configure ECS Fargate

  Push the API image to Amazon ECR and configure an ECS Fargate service to connect securely to RDS.

• Operate and Troubleshoot the AWS API Service

  Use CloudWatch logs, ECS health checks, and deployment events to diagnose and resolve service issues.

• Capstone Project: Deploy and Verify the Live Go API

  Deploy the complete Go API to ECS Fargate, verify live endpoints and PostgreSQL connectivity, and confirm operational logs in CloudWatch.
