Maybe have a StreamLogger.isSupported() method so you don't have to use window.ReadableStream everywhere. Then in create() you can also assert that it's supported.

Counting newlines might be more fair and/or fit your window better but I can see why you'd also do this instead.

I wonder if you might wanna throw 50000 in a config file since it's used in several spots.

npm/yarn and prettier always fight the formatting of these lines. I try to make prettier win since that's easier to keep up with.
Supports:
- Reading the head of a log
- Reading the tail of a log
- Following a log in one of two ways:
- Streaming the HTTP request (using fetch res.getReader)
- Polling the log endpoint (using EC timeouts)
Just verifying the log code works
Until they can be mocked, they can't be used
This will need to get better for testing the offset stitching logic in the polling case.

Supports:
In order to not destroy browsers, the log will only show 50k characters. When streaming or reading the tail, anything before the last 50k characters will be truncated. When reading the head, anything after the first 50k characters will be truncated.
Having scroll back is nice, and I want to make this better, but I think this is a good first iteration.
