CLI

Run registry-build from config roots, CI, or local package scripts.

The CLI is the normal runtime entrypoint. Run registry-build build from the package or app that owns the config and generated outputs.

Main command

registry-build build

The CLI discovers registry-build.config.* starting from the current working directory unless --config or --cwd is set.

Build flags

Flag	Purpose
`-c, --config <path>`	Use a specific config file
`--cwd <path>`	Change config discovery root
`--silent`	Hide banner and summary output
`--json`	Emit machine-readable build summary
`--verbose`	Print full error stack
`--changed-only`	Reuse cached work aggressively
`--changed <paths...>`	Narrow rebuild work to affected paths

Common examples

Default build

registry-build build

Use a specific config file

registry-build build --config ./configs/registry-build.config.ts

Run from CI with JSON output

registry-build build --json --silent

Warm local rebuild for changed files only

registry-build build --changed-only --changed ../../packages/registry-ui/src/button/button.tsx

Package script patterns

Minimal:

{
  "scripts": {
    "build:reg": "registry-build build"
  }
}

Split raw build and formatting:

{
  "scripts": {
    "build:reg": "bun run build:reg:cli && bun run format:reg",
    "build:reg:cli": "registry-build build",
    "format:reg": "bunx biome format --write ./__ui_registry__/index.tsx"
  }
}

build:reg is the default one-command workflow; build:reg:cli stays available for direct flag usage.

Exit behavior

Validation or load errors fail the command with a non-zero exit code.
--verbose includes the full stack for debugging.
--json is useful for CI, custom dashboards, or local tooling wrappers.

Config discovery rules

The loader searches for these filenames:

registry-build.config.ts
registry-build.config.mts
registry-build.config.cts
registry-build.config.js
registry-build.config.mjs
registry-build.config.cjs
registry-build.config.json

Config-relative paths are normalized as soon as the config is loaded. That prevents the usual confusion between current working directory and config file location.
