+# Unpub
+
+[![pub](https://img.shields.io/pub/v/unpub.svg)](https://pub.dev/packages/unpub)
+
+Unpub is a self-hosted private Dart Pub server for Enterprise, with a simple web interface to search and view packages information.
+
+## Screenshots
+
+![Screenshot](https://raw.githubusercontent.com/bytedance/unpub/master/assets/screenshot.png)
+
+## Usage
+
+### Command Line
+
+```sh
+pub global activate unpub
+unpub --database mongodb://localhost:27017/dart_pub # Replace this with production database uri
+```
+
+Unpub use mongodb as meta information store and file system as package(tarball) store by default.
+
+Dart API is also available for further customization.
+
+### Dart API
+
+```dart
+import 'package:mongo_dart/mongo_dart.dart';
+import 'package:unpub/unpub.dart' as unpub;
+
+main(List<String> args) async {
+  final db = Db('mongodb://localhost:27017/dart_pub');
+  await db.open(); // make sure the MongoDB connection opened
+
+  final app = unpub.App(
+    metaStore: unpub.MongoStore(db),
+    packageStore: unpub.FileStore('./unpub-packages'),
+  );
+
+  final server = await app.serve('0.0.0.0', 4000);
+  print('Serving at http://${server.address.host}:${server.port}');
+}
+```
+
+### Options
+
+| Option | Description | Default |
+| --- | --- | --- |
+| `metaStore` (Required) | Meta information store | - |
+| `packageStore` (Required) | Package(tarball) store | - |
+| `upstream` | Upstream url | https://pub.dev |
+| `googleapisProxy` | Http(s) proxy to call googleapis (to get uploader email) | - |
+| `uploadValidator` | See [Package validator](#package-validator) | - |
+
+
+### Usage behind reverse-proxy
+
+Using unpub behind reverse proxy(nginx or another), ensure you have necessary headers
+```sh
+proxy_set_header X-Forwarded-Host $host;
+proxy_set_header X-Forwarded-Server $host;
+proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+proxy_set_header X-Forwarded-Proto $scheme;
+
+# Workaround for: 
+# Asynchronous error HttpException: 
+# Trying to set 'Transfer-Encoding: Chunked' on HTTP 1.0 headers
+proxy_http_version 1.1;
+```
+
+### Package validator
+
+Naming conflicts is a common issue for private registry. A reasonable solution is to add prefix to reduce conflict probability.
+
+With `uploadValidator` you could check if uploaded package is valid.
+
+```dart
+var app = unpub.App(
+  // ...
+  uploadValidator: (Map<String, dynamic> pubspec, String uploaderEmail) {
+    // Only allow packages with some specified prefixes to be uploaded
+    var prefix = 'my_awesome_prefix_';
+    var name = pubspec['name'] as String;
+    if (!name.startsWith(prefix)) {
+      throw 'Package name should starts with $prefix';
+    }
+
+    // Also, you can check if uploader email is valid
+    if (!uploaderEmail.endsWith('@your-company.com')) {
+      throw 'Uploader email invalid';
+    }
+  }
+);
+```
+
+### Customize meta and package store
+
+Unpub is designed to be extensible. It is quite easy to customize your own meta store and package store.
+
+```dart
+import 'package:unpub/unpub.dart' as unpub;
+
+class MyAwesomeMetaStore extends unpub.MetaStore {
+  // Implement methods of MetaStore abstract class
+  // ...
+}
+
+class MyAwesomePackageStore extends unpub.PackageStore {
+  // Implement methods of PackageStore abstract class
+  // ...
+}
+
+// Then use it
+var app = unpub.App(
+  metaStore: MyAwesomeMetaStore(),
+  packageStore: MyAwesomePackageStore(),
+);
+```
+
+#### Available Package Stores
+
+1. [unpub_aws](https://github.com/bytedance/unpub/tree/master/unpub_aws): AWS S3 package store, maintained by [@CleanCode](https://github.com/Clean-Cole).
