Polkadot-JS
The Polkadot-JS project is a collection of tools, interfaces, and libraries around Polkadot and Substrate.
Note: While the project is named after "Polkadot", know that these tools, interfaces, and libraries are fully compatible with any Substrate based chain.
Polkadot-JS API
Polkadot-JS API 是一系列用于与 Polkadot 和 Substrate 的节点沟通的接口库。
The API provides application developers the ability to query a node and interact with the Polkadot or Substrate chains using Javascript.
开始
Polkadot-JS API 的开发者文档可在其网站中找到。 Follow the Getting Started guide to learn how to install and start using the Polkadot-JS API right away.
Polkadot-JS Apps
Polkadot-JS 应用是一个用作与 Polkadot 或 Substrate 开发节点互动而扩展性高的用户界面。
This is pre-built user-facing application, allowing access to all features available on Substrate chains.

与本地节点连接
To connect the Polkadot-JS Apps to your local node, you must go into Settings and change the "endpoint to connect to" to Local Node (127.0.0.1:9944).
Note: If you are connected to the Polkadot-JS Apps over a secure HTTPS connection, you will need to use a browser which also supports bridging to an insecure WebSocket endpoint. For example, Google Chrome supports this, but Mozilla Firefox does not.
Polkadot-JS 扩展
The Polkadot-JS Extension is a simple proof-of-concept for managing accounts in a browser extension and allowing the signing of extrinsics using these accounts. It also provides simple interface for interacting with extension-compliant dApps.
