# Custom title via passthrough
api-tools redocly build-docs -- --title "My API Documentation"

`redocly bundle`

Bundle API descriptions into a single file.

Note: The bundle command differs from the join command. The bundle command takes a root OpenAPI file as input and follows the $ref mentions to include all the referenced components into a single output file. The join command can combine multiple OpenAPI files into a single unified API description file.

Usage:

api-tools redocly bundle [input] [options]

Options:

[input] - Document path (default: openapi/openapi.yaml)
--output <path> - Output file path (default: dist/bundle/openapi.yaml)
--ext <extension> - Output extension (overrides --output extension)
- Choices: json, yaml, yml
--dereferenced - Generate fully dereferenced bundle (no $ref)
--config <file> - Config file path (overrides auto/bundled)

Examples:

# Bundle with defaults
api-tools redocly bundle

# Bundle to JSON
api-tools redocly bundle --ext json

# Fully dereferenced bundle
api-tools redocly bundle --dereferenced

# Custom output
api-tools redocly bundle --output dist/api-bundle.yaml

# Remove unused components via passthrough
api-tools redocly bundle -- --remove-unused-components

`redocly generate-arazzo`

Generate Arazzo workflow description from OpenAPI document.

Usage:

api-tools redocly generate-arazzo [input] [options]

Options:

[input] - OpenAPI document path (default: openapi/openapi.yaml)
--output <file> - Output file path (default: arazzo/auto-generated.arazzo.yaml)

Note: Generated Arazzo files require manual editing to be functional.

Examples:

# Generate from default OpenAPI
api-tools redocly generate-arazzo

# Custom output
api-tools redocly generate-arazzo --output arazzo/workflows.arazzo.yaml

`redocly init`

Create a default redocly.yaml config file.

api-tools redocly init [--force]

`redocly join`

Join multiple OpenAPI 3.x documents into a single file.

Note: The join command differs from the bundle command. The bundle command takes a root OpenAPI file as input and follows the $ref mentions to include all the referenced components into a single output file. The join command can combine multiple OpenAPI files into a single unified API description file. Unlike the bundle command, join does not execute preprocessors or decorators and combines the API description files as-is without modifying the original source files.

Usage:

api-tools redocly join <inputs...> [options]

Options:

<inputs...> - REQUIRED. At least 2 document paths to join
--output <file> - Output file path (default: dist/join/openapi.yaml)
--prefix-components-with-info-prop <property> - Prefix component names with info property to resolve conflicts (e.g., version, title)
--prefix-tags-with-info-prop <property> - Prefix tag names with info property (e.g., title, version)
--prefix-tags-with-filename - Prefix tag names with filename to resolve conflicts
--without-x-tag-groups - Skip automated x-tagGroups creation (avoids tag duplication)
--config <file> - Config file path (overrides auto/bundled)

Note: The options --prefix-tags-with-info-prop, --prefix-tags-with-filename, and --without-x-tag-groups are mutually exclusive.

Examples:

# Join two documents
api-tools redocly join api-1.yaml api-2.yaml

# Join with custom output
api-tools redocly join users-api.yaml orders-api.yaml \
  --output dist/combined-api.yaml

# Resolve component naming conflicts using version
api-tools redocly join museum-v1.yaml museum-v2.yaml \
  --prefix-components-with-info-prop version

# Prefix tags with title to avoid conflicts
api-tools redocly join first-api.yaml second-api.yaml \
  --prefix-tags-with-info-prop title

# Prefix tags with filename
api-tools redocly join api1/openapi.yaml api2/openapi.yaml \
  --prefix-tags-with-filename

# Skip x-tagGroups for duplicate tags
api-tools redocly join api-a.yaml api-b.yaml --without-x-tag-groups

# Advanced passthrough options
api-tools redocly join *.yaml -- --lint-config error

`redocly lint`

Validate and lint OpenAPI, AsyncAPI, and Arazzo documents using Redocly.

--openapi - Lint only OpenAPI at openapi/openapi.yaml
--asyncapi - Lint only AsyncAPI at asyncapi/asyncapi.yaml

Examples:

# Auto-detect and lint all specs
api-tools redocly lint

# Lint only OpenAPI
api-tools redocly lint --openapi

# JSON output
api-tools redocly lint --format json

# Custom config
api-tools redocly lint --config custom-redocly.yaml

`redocly respect`

Execute Arazzo workflow tests.

Usage:

api-tools redocly respect [input] [options]

Options:

[input] - Arazzo document path (default: arazzo/arazzo.yaml)
--workflow <names...> - Run only specified workflows
--skip <names...> - Skip specified workflows (conflicts with --workflow)
--verbose - Enable verbose output
--input <params...> - Workflow input parameters (key=value or JSON)
--server <overrides...> - Server overrides (name=url)
--json-output <file> - Save results to JSON file
--har-output <file> - Save HTTP interactions to HAR file

# Custom ruleset

# Passthrough advanced options
api-tools spectral lint -- --ignore-unknown-format

Default File Locations

The tool expects the following directory structure:

project/
├── openapi/
│   └── openapi.yaml        # Main OpenAPI spec
├── asyncapi/
│   └── asyncapi.yaml       # Main AsyncAPI spec
├── arazzo/
│   ├── arazzo.yaml         # Production Arazzo workflows
│   └── auto-generated.arazzo.yaml  # Generated starter
└── dist/
    ├── bundle/
    │   ├── openapi.yaml    # OpenAPI bundled output
    │   └── asyncapi.yaml   # AsyncAPI bundled output
    ├── format/
    │   └── asyncapi.json   # AsyncAPI format output
    ├── generated/          # AsyncAPI template output
    ├── join/
    │   └── openapi.yaml    # Joined output
    └── docs/
        ├── openapi.html    # OpenAPI docs
        └── asyncapi.html   # AsyncAPI docs (or asyncapi/ for multi-file)

Configuration Files

Auto-Discovery

The tool automatically discovers local config files:

.spectral.yaml, .spectral.yml, .spectral.json, .spectral.js, .spectral.mjs, spectral.yaml, spectral.yml, spectral.json, spectral.js, spectral.mjs
.redocly.yaml, .redocly.yml, redocly.yaml, redocly.yml

Bundled Defaults

If no local config exists, opinionated bundled configs are used with stricter-than-default rules:

Spectral: defaults/spectral.yaml - Comprehensive OpenAPI/AsyncAPI/Arazzo validation
Redocly: defaults/redocly.yaml - Strict API design standards

These bundled configs enforce best practices and may be more restrictive than upstream tool defaults. Create a local config file to customize rules for your project.

Custom Configs

Override with CLI options:

api-tools spectral lint --ruleset custom/.spectral.yaml
api-tools redocly lint --config custom/redocly.yaml

Passthrough Arguments

For advanced options not exposed by the wrapper, use -- to pass arguments directly to the underlying tool:

# Spectral advanced options
api-tools spectral lint -- --ignore-unknown-format

# Redocly advanced options
api-tools redocly bundle -- --remove-unused-components
api-tools redocly respect -- --max-steps 100 --execution-timeout 1800000

Troubleshooting

Command not found

Ensure the package is installed and npm scripts are configured:

npm install -D @bymbly/api-tools@latest

Config not found

Check config file names and locations. Use --config or --ruleset to specify custom paths.

Bundled config issues

To use your own config instead of bundled defaults, create a local config file that will be auto-discovered.
