LP Learning

Foundation

Go for JS Developers

Types, zero values, multiple returns, no exceptions — mental model shift from JS

Structs, interfaces (implicit), pointers, slices, maps, defer

error type, nil-check pattern, fmt.Errorf, errors.As/Is, panic vs return

Craft

Naming, small interfaces, accept interfaces/return structs, table-driven tests

Ignoring errors, goroutine leaks, global state, panic abuse

Goroutines, channels, context, sync primitives, errgroup — with real LP examples

Project

Git Flow & Commits

Branch strategy and commit conventions for CLM projects

Annotated repo layout — where to add handlers, services, repos

Libraries & Integrations

Fiber, GORM, MongoDB, Redis, Kafka, ECI, Viper, retry, rate limit, transactions

Project Standards

Handler→Service→Repo rules, Fiber patterns, repository interfaces, DI, zlog

main.go → middleware chain → handler → response. Graceful shutdown.

Dev Environment

Clone, .env setup, make run/build/tidy, docker-compose up — first run checklist

Unit tests with mock repositories, table-driven tests, make test-coverage

make build, Dockerfile, GitLab CI, blue/green deployment strategy

Change Data Capture

CDC concepts, Kafka JDBC sink connector, DB→topic pipeline, failure modes
