Lint your package.json before build, give you better exports

⚠️   ./dist/index.js
⚠️ Cannot export `import` field with .cjs extension in ESM package, only .js and .mjs extensions are allowed

Clean your dist folder before building

If you dont want to auto clean build bundles, just use --no-clean option

bunchee --no-clean # clean is by default

development and production export conditions

src/index.js can be injected with NODE_ENV based on the export conditon when using development or production

{
   "exports": {
      "development":  "./dist/index.development.js",
      "production":  "./dist/index.production.js",
   }
}
