dust-hive

What is dust-hive?

dust-hive is a CLI tool for running multiple isolated Dust development environments simultaneously. Each environment gets its own:

• Git worktree (separate branch)
• Port range (no conflicts between environments)
• Docker containers (isolated volumes)
• Database instances (Postgres, Qdrant, Elasticsearch)

Detecting a dust-hive Environment

To check if you're currently running in a dust-hive environment:

1. Check working directory: dust-hive worktrees are located at ~/dust-hive/{env-name}/
2. Check for worktree: The .git file (not directory) indicates a git worktree

# Check if in worktree path
pwd | grep -q "$HOME/dust-hive/" && echo "In dust-hive environment"

Environment States

Environments can be in one of three states:

State	What's Running	Can Run Tests?
stopped	Nothing	No
cold	SDK watch only	Yes (front tests use shared test DB)
warm	All services (front, core, connectors, oauth, workers) + Docker	Yes

Check the current state:

dust-hive status [ENV_NAME]

Environment Variables (direnv)

Each dust-hive worktree contains a .envrc file that automatically loads environment variables when you cd into the directory. This is powered by direnv.

What this means:

• Environment variables (ports, database URIs, API keys, etc.) are automatically available
• Variables like FRONT_DATABASE_URI, CORE_API, CONNECTORS_API are pre-configured for the environment's port range

If environment variables are missing, manually source the environment:

source ~/.dust-hive/envs/{ENV_NAME}/env.sh

Port Allocation

Each environment gets a 1000-port range starting at 10000:

• 1st env: 10000-10999 (front:10000, core:10001, connectors:10002, oauth:10006)
• 2nd env: 11000-11999
• 3rd env: 12000-12999

Running Linters, Type Checks, and Builds

For dust-hive itself (in x/henry/dust-hive/):

# Run ALL checks before committing (MANDATORY)
bun run check

# Individual checks
bun run typecheck    # TypeScript strict checks
bun run lint         # Biome linting
bun run lint:fix     # Auto-fix lint issues
bun run format       # Code formatting
bun run test         # All tests

For Dust apps (in worktree or main repo):

# TypeScript SDK (watch is running - check logs if issues after SDK changes)
dust-hive logs [ENV_NAME] sdk

# Front (Next.js)
cd front && npm run lint                                              # ESLint
cd front && NODE_OPTIONS="--max-old-space-size=8192" npx tsgo --noEmit  # Type-check
cd front && npm run build                                             # Build

# Core (Rust)
cd core && cargo check && cargo clippy

# Connectors
cd connectors && npm run lint   # ESLint
cd connectors && npm run build  # Type-check + build

# OAuth (Rust)
cd oauth && cargo check && cargo clippy

Quick health check after warming:

curl -sf http://localhost:10000/api/healthz  # front
curl -sf http://localhost:10001/             # core

Running Front Tests in Cold Environments

The front project requires a Postgres database and Redis to run tests. dust-hive provides shared test containers that allow running front tests without warming up the full environment.

How it works

• A shared Postgres container runs on port 5433 (started by dust-hive up)
• A shared Redis container runs on port 6479 (started by dust-hive up)
• Each environment gets its own test database: dust_front_test_{env_name}
• TEST_FRONT_DATABASE_URI and TEST_REDIS_URI are already set in each environment's env.sh

Running front tests

IMPORTANT: You must set NODE_ENV=test when running front tests.

# From any cold environment, run front tests directly
cd front && NODE_ENV=test npm test

# Run specific test file
cd front && NODE_ENV=test npm test lib/resources/user_resource.test.ts

# Run with verbose output
cd front && NODE_ENV=test npm test --reporter verbose path/to/test.test.ts

No need to warm the environment - the shared test Postgres and Redis are always available.

Troubleshooting front tests

If front tests fail with database connection errors:

1. Check if test postgres is running: docker ps | grep dust-hive-test-postgres
2. If not running, start it: docker start dust-hive-test-postgres
3. Verify the database exists: docker exec dust-hive-test-postgres psql -U test -l

Known Issues

Node modules structure

In dust-hive environments, node_modules for front and connectors uses a shallow copy structure:

• A real node_modules directory with symlinks to packages from the main repo
• @dust-tt/client is overridden to point to the worktree's SDK (ensuring correct type resolution)

Running npm install requires manual cleanup:

rm -rf node_modules && npm install

SDK watcher doesn't detect changes after git rebase

The SDK watcher uses nodemon which relies on filesystem events. When running git rebase, git pull, or git checkout, nodemon may not detect file changes.

Symptoms: Type errors in front about missing types that should exist in the SDK.

Solution: Restart the SDK watcher after git operations that change SDK files:

dust-hive restart [ENV_NAME] sdk

Or manually trigger a rebuild:

touch sdks/js/src/types.ts
