This repo is a simple demo of how to use aelf-bridge.

# using npm
npm i
# using yarn
yarn

Since there are two ways Dapp can communicate with the AElf chain, aelf-command provides the socket way.

1. start Dapp server in aelf-command

   You need to install aelf-command before next step.

   npm i aelf-command -g

   start the Dapp server

   aelf-command dapp-server

   by default, the Dapp server will listen on port 35443

2. start webpack

   In project directory

   npm run dev

   open the page http://0.0.0.0:9527/dapp.html.

1. add chain node url in .env

   touch .env

   add your own END_POINT

   END_POINT=http://127.0.0.1:8000

2. start webpack

   Firstly, init aelf-bridge with post message channel javascript const bridgeInstance = new AElfBridge(); In project directory

   npm run dev

   open the page http://0.0.0.0:9527/container.html. When you inspect this page, you can find an iframe inside the HTML, the iframe holds the dapp page.

   There are two pages in this repo, as you can see in the directory src/pages/, there are dapp and dappContainer.

   Since Dapp needs to interact with Native apps which holds wallet info, we provide dappContainer to support your development. Think dappContainer is a wallet App, which hold the wallet info and can interact with AElf chain node directly. And it provides the abilities to support Dapp communication. Any Developers can use this page as the Native app to develop Dapp.

   dappContainer uses iframe and rewrite iframe's postMessage, so dapp can send messages to dappContainer

   dapp is a simple Dapp demo which uses aelf-bridge to interact with dappContainer, you can take it as an example and write your own code.
