How to create a separate chat via API?

[Aviv1000]

import ollama from 'ollama'

const message = { role: 'user', content: 'What color of the sky?' }
const response = await ollama.chat({ model: 'llama2', messages: [message], stream: true })
for await (const part of response) {
  process.stdout.write(part.message.content)
}

const message2 = { role: 'user', content: 'What was my first prompt?' }
const response = await ollama.chat({ model: 'llama2', messages: [message2], stream: true })
for await (const part of response) {
  process.stdout.write(part.message.content)
}
//result: your first prompt was "What color of the sky?"

The documentation is not clear enough,
How am I supposed to save a session of the current conversation (to continue talking later) and create a new separate chat conversation?

Just tested this exact same code and the same doesn't happen for me

[imareo]

for one separate chat (in pseudo code):

1. create empty chat=[] or [{role:'system', content:'...you system prompt here...'}]
2. add new message: chat=[...chat, message]
3. await ollama.chat({ model: 'llama2', messages: chat, stream: true })
4. after get response add answer: chat=[...chat, answer] (answer must be {role:'assistant', content: 'ai bla-bla-bla'})
5. goto 2

save this chat for late as you wish
