Asynchronous reading of data from Stream, such as uint8, int64, null terminated string

AsyncBinaryStream

This library helps in developing or implementing protocols that use functions similar to those of DataView in asynchronous form.

Example of usage:

const AsyncBinaryStream = require("async-binary-stream")

// "someDuplexStream" can be Readable but cannot be used for "write" and "flush" methods
// Same with Writable
// Can take Socket or another Duplex/Readable/Writable implementation
let binaryStream = new AsyncBinaryStream(someDuplexStream)

;(async () => {
    let num = await binaryStream.readUInt64BE()
    
    binaryStream.writeNullTerminatingString(`UInt64BE bytes: `)
    binaryStream.writeUInt64BE(num)
    
    // Send all writed data
    await binaryStream.flush()
})()
