@percy/config
Handles loading and adding options to Percy configuration files. Uses cosmiconfig to load configuration files and JSON schema with AJV to validate those configuration files.

Loading config files

The .load() method will load and validate a configuation file, optionally merging it with any provided overrides. If no path is provided, will search for the first supported config found from the current directory up to the home directoy. Configuration files are cached and reused unless reload is true.
import PercyConfig from '@percy/config'

// loading is done synchronously
const config = PercyConfig.load(options)

Options

  • path — Config file path or directory containing a config file
  • overrides — Config option overrides
  • reload — Do not use cached config (default false)
  • bail — Return undefined when failing validation (default false)
  • print — Print info and error logs (default false)

Supported files

  • "percy" entry in package.json
  • .percyrc YAML or JSON file
  • .percy.json JSON file
  • .percy.yaml or .percy.yml YAML file
  • .percy.js or percy.config.js file that exports an object

Extending config options

The .addSchema() function will add a sub-schema to the Percy configuration file which will be parsed and validated when PercyConfig.load() is called. See JSON schema for possible schema options.
import PercyConfig from '@percy/config'

PercyConfig.addSchema({
  propertyName: JSONSchema
})
