Using it for react-native throws [TypeError: Cannot read property 'toLowerCase' of undefined]

[BhavinPatel04]

Usage

import ollama from 'ollama/dist/browser';
const response = await ollama.chat({
  model: 'llama3.2:1b',
  messages: [{
    role: 'user',
    content: 'Why is the sky blue?',
  }],
});

Issue

While using with react-native, it throws the below error

[TypeError: Cannot read property 'toLowerCase' of undefined]

RootCause

After debugging it seems the error is thrown in getPlatform() on line#95
This is because navigator.platform is deprecated.

Workaround

(In case someone is stuck here as well)

const fetchResponse = await fetch('http://localhost:11434/api/chat', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    model: 'llama3.2:1b',
    messages: [{
      role: 'user',
      content: 'Why is the sky blue?',
    }],
    stream: false
  }),
});
const response = await fetchResponse.json();
