I don't think the EventSource class will work here so we need to write our own parser for it. I don't think this is a compatibility issue that's on us, OpenAI does the same in their client here, but it is unfortunate

const decoder = new TextDecoder()
while (true) {
const { done, value } = await reader.read()
if (done) {
break
}

const decodedValue = decoder.decode(value)
const lines = decodedValue.split('\n')

let i = 0
while (i < lines.length) {
const line = lines[i]
if (line.length === 0) {
i++
continue
}

if (!line.startsWith('event: ')) {
responseText.innerHTML = `Unexpected event type line: ${line}`
return
}

const dataLine = lines[i + 1]
if (!dataLine.startsWith('data: ')) {
responseText.innerHTML = `Unexpected data line: ${dataLine}`
return
}

const eventType = line.substring('event: '.length)
const data = dataLine.substring('data: '.length)
const json = JSON.parse(data)
if (eventType === 'content') {
const { response } = json
responseText.innerHTML += response
} else if (eventType === 'error') {
const { message, code } = data
responseText.innerHTML = `Error: ${message} (${code})`
}

i += 2
}
}
}
