Usage

# Validate with a custom schema
config-validate -c config.json -s schema.json

# Validate common configs (built-in schemas for package.json, tsconfig.json)
config-validate -c package.json

# Strict mode — disallow additional properties
config-validate -c config.yaml -s schema.json --strict

# JSON output for CI pipelines
config-validate -c config.json -s schema.json --json

# Verbose — list all checked fields
config-validate -c package.json --verbose

Options

| Flag | Description | |------|-------------| | -c, --config <path> | Path to the config file (JSON or YAML) | | -s, --schema <path> | Path to the JSON Schema file | | --strict | Disallow additional properties | | --json | Output results as JSON | | --verbose | Show all validated fields | | -V, --version | Show version | | -h, --help | Show help |

Built-in Schemas

When no -s flag is provided, the tool uses built-in schemas for:

• package.json — validates name, version, scripts, dependencies
• tsconfig.json — validates compilerOptions, include, exclude

Exit Codes

• 0 — config is valid
• 1 — config is invalid or an error occurred
