A Portal into the Polkadot network. Provides a view and interaction layer from a browser.

This can be accessed as a hosted application via https://polkadot.js.org/apps/ or via https://poc-2.polkadot.io with the latter not requiring a locally-hosted node.

The repo is split into a number of packages, each representing an application. These are -

• apps This is the main entry point. It handles the selection sidebar and routing to the specific application being displayed.
• app-accounts A basic account management app.
• app-addresses A basic address management app.
• app-explorer A simple block explorer. It only shows the most recent blocks, updating as they become available.
• app-extrinsics Submission of extrinsics to a node.
• app-rpc Sumission of raw data to RPC endpoints.
• app-staking A basic staking management app, allowing staking and nominations.
• app-storage A simple node storage query application. Multiple queries can be queued and updates as new values become available.
• app-toolbox Utilities to manage data.
• app-vanitygen A toy that allows you to generate vanity addresses. Running yarn run vanitygen --match <string> runs the generator as a Node CLI app. (Orders of a magnitude faster due to the use of libsoldium bindings)

In addition the following libraries are also included in the repo. These are to be moved to the @polkadot/ui repository once it reaches a base level of stability and usability. (At this point with the framework being tested on the apps above, it makes development easier having it close)

• ui-app A reactive (using RxJS) application framework with a number of useful shared components.
• ui-keyring A browser-specific wrapper around the base @polkadot/util-keyring library.
• ui-signer Signer implementation for apps.
• ui-identicon Identity icon generator with raw publicKey as input
• ui-react A collection of base React components
• ui-react-rx Base components that use the RxJS Observable APIs

Contributions are welcome!

To start off, this repo (along with others in the @polkadot family) uses yarn workspaces to organise the code. As such, after cloning dependencies should be installed via yarn, not via npm, the latter will result in broken dependencies.

To get started -

1. Clone the repo locally, via git clone https://github.com/polkadot-js/apps <optional local path>
2. Ensure that you have a recent version of Node.js, for development purposes Node >=10.1.0 is required.
3. Ensure that you have a recent version of Yarn, for development purposes Yarn >=1.3.2 is required.
4. Install the dependencies by running yarn
5. Ready! Now you can launch the UI (assuming you have a local Polkadot Node running), via yarn run start
6. Access the UI via http://localhost:3000

Should you not run a local Node, you can connect to a remote node on the POC-2 network with the WS_URL environment variable. For example - the apps entry point can be launched with a WebSocket connection to Polkadot POC-2 with WS_URL=wss://poc-2.polkadot.io:9944 yarn run start and accessing the application of http://localhost:3000

There are additional environment UI flags that change both the theme and mode -

• Running with UI_MODE=light|full switches from a full (the default) to a light mode interface that only has specific applications highlighted.
• Running with UI_THEME=substrate|polkadot switches from a Polkadot theme (the default) to a Substrate-branded UI

Demos for the different libraries can be viewed with yarn run demo:<name> and then browsing to http://localhost:3000. Available demo -

• yarn run demo:identicon
• yarn run demo:ui
• yarn run demo:rx
