# ============================================================================
# DEVELOPERS NOTE:
# THE PURPOSE OF THIS DOCKERFILE IS TO BUILD THE MAPLEPRESS BACKEND
# EXECUTABLE IN A CONTAINER FOR DEVELOPMENT PURPOSES ON YOUR
# MACHINE. DO NOT RUN THIS IN PRODUCTION ENVIRONMENT.

# Start with the official Golang image
FROM golang:1.24.4

# ============================================================================
# SETUP PROJECT DIRECTORY STRUCTURE
# ============================================================================
# Set the working directory first
WORKDIR /go/src/codeberg.org/mapleopentech/monorepo/cloud/maplepress-backend

# ============================================================================
# DEPENDENCY MANAGEMENT (DO THIS FIRST FOR BETTER CACHING)
# ============================================================================
# Copy dependency files first to take advantage of Docker layer caching
COPY go.mod go.sum ./
# Download all dependencies
RUN go mod download

# INSTALL DEVELOPMENT TOOLS
# ============================================================================
# Install CompileDaemon for hot reloading
RUN go install github.com/githubnemo/CompileDaemon@latest

# Install Wire for dependency injection
RUN go install github.com/google/wire/cmd/wire@latest

# Install goimports for code formatting
RUN go install golang.org/x/tools/cmd/goimports@latest

# Install staticcheck for linting
RUN go install honnef.co/go/tools/cmd/staticcheck@latest
