Usage

Install:

npm add browserslist-load-config -D

loadConfig

import { loadConfig } from "browserslist-load-config";

// Pass a path to the configuration file
const config = loadConfig({
  /**
   * Specify the directory where the configuration file is located
   */
  path: "./path/to/project/root",

  /**
   * Specify the environment to load
   * @default "production"
   */
  env: "production",
});

// Pass a browserslist config directly
const config = loadConfig({
  /**
   * Specify the directory where the configuration file is located
   */
  path: "./path/to/project/root",

  /**
   * Specify the environment to load
   * @default "production"
   */
  env: "production",
});

console.log(config);
/**
 * [
 *   // browserslist config
 * ]
 */

If both config and path are provided, config will be used.

findConfig

import { findConfig } from "browserslist-load-config";

const config = findConfig("./path/to/project/root");

console.log(config);
/**
 * {
 *   defaults: [
 *     // default browserslist config
 *   ],
 *   development: [
 *     // development browserslist config
 *   ],
 *   production: [
 *     // production browserslist config
 *   ],
