Code examples

Environments

• Browser depends on window.crypto
• Nodejs >= v10.0

In the Nodejs environment, gRPC is supported and used by default, you can choose to close it, and still use Http to request

XuperSDK.getInstance({
    ...,
    env: {
        node: {
            disableGRPC: true // disable gRPC
        }
    }
})

How to build a test environment

Read the documentation , compile and deploy XuperChain

Use XuperChain Docker image to build a single-node service

1. Pull image (XuperChian v3.7 - Repository)

   docker pull smilingxinyi/xuperchain

2. Start container

   docker run -d -p 8098:8098 -p 37101:37101 -p 47101:47101 –name xc smilingxinyi/xuperchain

Plugin

Endorsement service plugin

The plugin must be used on the public network

EndorsementPlugin

Example:

const params = {
    server: process.env.ENDORSE_SERVER, // ip, port
    fee: process.env.FEE, // fee
    endorseServiceCheckAddr: process.env.SERVICE_SIGN_ADDRESS, // sign address
    endorseServiceFeeAddr: process.env.SERVICE_FEE_ADDRESS // fee address
}

const xsdk = new XuperSDK({
    node,
    chain,
    plugins: [
        EndorsementPlugin({
            transfer: params,
            makeTransaction: params
        })
    ]
});
