@istanbuljs/load-nyc-config

@istanbuljs/load-nyc-config

The utility function which NYC uses to load configuration. This can be used by outside programs to calculate the configuration. Command-line arguments are not considered by this function.

const {loadNycConfig} = require('@istanbuljs/load-nyc-config');

console.log(loadNycConfig());

loadNycConfig([options])

options.cwd

Type: string Default: cwd from parent nyc process or process.cwd()

options.nycrcPath

Type: string Default: undefined

Name of the file containing nyc configuration. This can be a relative or absolute path. Relative paths can exist at options.cwd or any parent directory. If an nycrc is specified but cannot be found an exception is thrown.

If no nycrc option is provided the default priority of config files are:

• .nycrc
• .nycrc.json
• .nycrc.yml
• .nycrc.yaml
• nyc.config.js

Configuration merging

Configuration is first loaded from package.json if found, this serves as the package defaults. These options can be overridden by an nycrc if found. Arrays are not merged, so if package.json sets "require": ["@babel/register"] and .nycrc sets "require": ["esm"] the effective require setting will only include "esm".

nyc

While nyc itself is primarily a command-line tool for capturing code coverage, it inherently deals with loading and applying configuration for its operation. Compared to @istanbuljs/load-nyc-config, nyc offers a broader set of functionalities including instrumentation, reporting, and configuration management as part of its core features.

config

The 'config' package is used for managing configurations across Node.js applications. It doesn't specifically target nyc configurations but provides a general-purpose solution for loading and merging configurations from various sources. Unlike @istanbuljs/load-nyc-config, it's not tailored to code coverage tools but can be adapted for various configuration needs.
