Sockets joining two messages. about node

Do you want repo of whole this process?

+"\u0004" at write, and parsing on recieving socket solves the problem, but IMO it should be automatic, so reclassify this as feature request if you wish.

Yes, providing reproduction steps (and code) is the best way for people to see and understand what went wrong

I don't know if it's expected, but it mostly doesn't happen.

Like I understand, if it's sends in a buffer at one time it's two different thing, but I never managed to break the JSON.parse being in on('data', like that, I fixed it with unicode symbol, but anyhow, it feels broken.

Now I see, that I should write my own encoding, where there is size of JSON specified and read up buffer up to that length, but it takes away ease of javascript, I expected it to be done by default.

Solution I have is to encode/decode JSON String by following thing:

const { Buffer } = require('node:buffer')

const encode = (string, encoding)=>{
    string = Buffer.from(string, encoding)
    let length = string.byteLength
    length = Buffer.from(`<${length}>`)
    let buffer = Buffer.concat([length, string])
    return buffer
}

const decode = (buffer, encoding, perChunk)=>{
    let stop = false
    while(!stop) {
        let index = buffer.indexOf('>')
        let sub = buffer.subarray(1, index)
        let length = Number(sub.toString())
        let ourChunk = buffer.subarray(index+1, length+index+1)
        perChunk(ourChunk.toString())
        buffer = buffer.subarray(length+index+1)
        if(buffer.byteLength===0) stop = true
    }
}

module.exports = (encoding)=>{
    return {
        encode: (string)=>{
            return encode(string, encoding)
        },
        decode: (buffer, perChunk)=>{
            return decode(buffer, encoding, perChunk)
        }
    }
}
