just

Overview

just is a command runner — like make but without the build system baggage. Define commands in a justfile, run with just <command>.

Instructions

Step 1: Install

brew install just

Step 2: Justfile

# justfile — Project commands
set dotenv-load

default: dev

dev:
    npm run dev

test *args:
    npm test {{args}}

build:
    npm run build

db-reset: && db-migrate db-seed
    npx prisma migrate reset --force

db-migrate:
    npx prisma migrate deploy

db-seed:
    npx prisma db seed

deploy env="staging":
    echo "Deploying to {{env}}..."
    npx vercel deploy

up:
    docker compose up -d

down:
    docker compose down

logs service="app":
    docker compose logs -f {{service}}

Guidelines

• Unlike make, just doesn't track file dependencies — purely a command runner.
• Supports arguments with defaults: deploy env="staging".
• just --list shows all available commands.
