+# @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.
+
+```js
+const {loadNycConfig} = require('@istanbuljs/load-nyc-config');
+
+(async () {
+  console.log(await 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
+* nyc.config.cjs
+* nyc.config.mjs
+
+## 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"`.
+
+## isLoading
+
+```js
+const {isLoading} = require('@istanbuljs/load-nyc-config');
+
+console.log(isLoading());
+```
+
+In some cases source transformation hooks can get installed before the configuration is
+loaded.  This allows hooks to ignore source loads that occur during configuration load.
