Setup Dev Environment Skill

Setup Dev Environment Skill

Use this skill when initializing or resetting the development environment.

---

When to Use

• First time setting up the project after cloning
• After pulling major changes that affect dependencies or database schema
• When the local environment is in a broken state and needs a fresh start
• When switching between branches with different dependency requirements

Prerequisites

• Docker and Docker Compose installed
• Go toolchain installed
• .env file configured (see README for required values)

Initialization Options

Option 1: Full Setup (with Node.js dependencies)

Use when you need to work with the tarkov.dev GraphQL schema or regenerate the client:

task init

This runs:

1. deps:install:go - Installs Go tools
2. deps:install:node - Installs Node.js tools
3. migrate:up - Applies all database migrations

Option 2: Go-Only Setup (recommended for most development)

Use for general development when you don't need to update external schemas:

task init:go-only

This runs:

1. deps:install:go - Installs Go tools (golangci-lint, goose, genqlient)
2. migrate:up - Applies all database migrations

What Gets Set Up

1. Go Dependencies: Linter, migration tool, GraphQL client generator
2. Docker Services: PostgreSQL database (and any other services in docker-compose.yml)
3. Database Schema: All migrations applied to create tables and indexes
4. Environment: Loads variables from .env file

Verification

After initialization, verify the setup:

# Check Docker services are running
docker compose ps

# Run unit tests (no database needed)
task test:unit

# Run integration tests (uses database)
task test:integration

Troubleshooting

Database connection fails:

• Ensure .env has correct POSTGRES_* values
• Check if port 5432 is already in use: lsof -i :5432
• View logs: docker compose logs postgres

Migration errors:

• Check if previous migrations ran: docker compose exec postgres psql -U $POSTGRES_USER -d $POSTGRES_DB -c "\dt"
• Rollback and reapply: task migrate:down && task migrate:up

Go dependencies fail to install:

• Ensure Go is properly installed: go version
• Check GOPATH: go env GOPATH
• Manually install failing tool, e.g.: go install github.com/​golangci/​golangci-lint/​cmd/​golangci-lint@latest

Clean Reset

If you need to completely reset the environment:

# Stop and remove all containers and volumes
task compose:down
docker compose down -v

# Clean build artifacts
task clean

# Re-initialize
task init:go-only

Next Steps

After setup, you can:

• Start the API: task api:start
• Start the importer: task importer:start
• Start the evaluator: task evaluator:start
• Run tests: task test:unit or task test:integration
