Local development

Run the full Carbon stack locally with the crbn CLI — isolated per-worktree environments.

Carbon is a pnpm + Turborepo monorepo — the ERP and MES apps plus their shared packages. Local development runs on the crbn CLI (in packages/dev), a per-worktree environment manager: every git worktree gets its own compose stack — Postgres, Kong, Supabase, Inngest, and Inbucket (mail) — with its own ports, Redis database, and JWT credentials. So you can work several branches at once without their stacks colliding.

Setup

Add crbn to your PATH (it installs a small shell wrapper):

source ./setup.sh

Bring up the stack

From any worktree:

crbn up

This boots the compose stack and the ERP and MES dev servers, and generates a .env.local with per-worktree ports, local Supabase keys, REDIS_URL, Inngest dev settings, and DEV_BYPASS_EMAIL so you can sign in without a magic link. Reach the apps at their portless .dev URLs or at localhost:<port>.

HEADS UP

DEV_BYPASS_EMAIL is local-only — it signs you in as that email with no magic link. Never set it in a deployed environment.

Stack commands

Command	What it does
`crbn up`	Boot the compose stack and apps.
`crbn up --no-portless`	Localhost mode — fixed ports (API `54321`, ERP `3000`, MES `3001`).
`crbn up --no-apps`	Services only — Postgres, Kong, Supabase, Inngest, mail.
`crbn up --no-migrate`	Skip database migrations on boot.
`crbn up --no-regen`	Skip type and Swagger regeneration.
`crbn up --borrow`	Reuse another worktree's already-running containers.
`crbn up --pull`	Force `docker compose pull` even if images exist locally.
`crbn down`	Stop the stack (volumes preserved).
`crbn reset`	Wipe volumes and flush the Redis db, then boot again.
`crbn migrate`	Apply database migrations against the running stack.
`crbn status`	Show port assignments and container health.

NOTE

pnpm dev is shorthand for crbn up --no-portless — localhost mode on fixed ports.

Worktrees

Each branch gets an isolated worktree and stack, so several can run side by side.

Command	What it does
`crbn checkout <branch>`	Switch into a branch's worktree, creating it if missing (auto-fetches from origin).
`crbn checkout -b <branch>`	Create a new branch and worktree from `--base` (default HEAD).
`crbn checkout <pr-number>`	Fetch a PR's head into a `pr-<num>` branch and worktree.
`crbn checkout main`	Return to the main checkout (never a separate worktree).
`crbn new [branch]`	Create a worktree interactively.
`crbn list`	List all worktrees with their stack status.
`crbn remove`	Multi-select worktrees to tear down; add `--prune` to delete the branch too.

Portless vs localhost

By default crbn up uses portless to serve a TLS .dev URL per app (for example erp.<branch>.dev), giving each worktree stable, shareable hostnames. Pass --no-portless — or set CARBON_PORTLESS=0 — for localhost mode on fixed ports:

Service	Port
Supabase API (Kong)	`54321`
ERP	`3000`
MES	`3001`

Sync files from main

A fresh worktree doesn't carry your gitignored local files. Pull them across from the main checkout:

Command	What it does
`crbn copy <file…>`	Copy specific file(s) from the main checkout into this worktree.
`crbn env sync`	Copy the files listed in `package.json` under `crbn.copy`.

Configuration

Your local settings live in the generated .env.local. See Environment variables for the full configuration surface, and Deployment to self-host on AWS.
