This package is a Node.js TypeScript wrapper around [ChatGPT](https://openai.com/blog/chatgpt) by [OpenAI](https://openai.com).
You can use it to start experimenting with ChatGPT by integrating it into websites, chatbots, etc...
## Auth
It uses headless Chromium via [Playwright](https://playwright.dev) under the hood, so **you still need to have access to ChatGPT**, but it makes it much easier to access programatically.
Chromium is opened in non-headless mode by default, which is important because the first time you run `ChatGPTAPI`.init, you'll need to log in manually. Chromium is launched with a persistent context, so you shouldn't need to keep re-logging in after the first time.
## Usage
```ts
async function example() {
const api = new ChatGPTAPI()
// open chromium and wait until the user has logged in
await api.init({ auth: 'blocking' })
// send a message and wait for a complete response, then parse it as markdown
const response = await api.sendMessage(
'Write a python version of bubble sort. Do not include example usage.'
)
console.log(response)
}
// which outputs:
/*
Here is an implementation of bubble sort in Python:
\`\`\`python
def bubble_sort(lst):
# Set the initial flag to True to start the loop
swapped = True
# Keep looping until there are no more swaps
while swapped:
# Set the flag to False initially
swapped = False
# Loop through the list
for i in range(len(lst) - 1):
# If the current element is greater than the next element,
# swap them and set the flag to True
if lst[i] > lst[i + 1]:
lst[i], lst[i + 1] = lst[i + 1], lst[i]
swapped = True
# Return the sorted list
return lst
\`\`\`
*/
```
Here's the same response rendered as markdown:

```python
def bubble_sort(lst):
# Set the initial flag to True to start the loop
swapped = True
# Keep looping until there are no more swaps
while swapped:
# Set the flag to False initially
swapped = False
# Loop through the list
for i in range(len(lst) - 1):
# If the current element is greater than the next element,
# swap them and set the flag to True
if lst[i] > lst[i + 1]:
lst[i], lst[i + 1] = lst[i + 1], lst[i]
swapped = True
# Return the sorted list
return lst
```
Note that the default functionality is to parse ChatGPT responses as markdown using [html-to-md](https://github.com/stonehank/html-to-md). I've found the markdown quality to be excellent in my testing, but if you'd rather output plaintext, just pass `{ markdown: false }` to the `ChatGPTAPI` constructor.
