Blob is too big.

[SunnyQjm]

Now, I want to use webtorrent API to share a file (seed it). In the same time, use the magnetURI to download this file.
But if this file too big. (For example in chrome, the file bigger than 800M). Use "file.getBlob()" or "file.getBlobUrl" can not create a Blob Object. The Web page will cash.

I have test that the demo web "https://instant.io/" also have this problem.

If I want to trans a Big file, How can I fix it.

There is certainly a hard limit of the browser, resp. the machines RAM, but also at https://webtorrent.io/docs ->file.appendTo->opts->maxBlobLength->default: 200 * 1000 * 1000 bytes

@SunnyQjm,

What browser are you using @SunnyQjm?

Browsers handle blobs differently, with some storing them solely in memory while others store the blob on disk, a good breakdown of the different limits between browsers can be seen here.

The Web page will cash.

Chrome specifically states that

Creating a lot of blobs, especially if they are very large blobs, can cause the renderer memory to grow too fast and result in an OOM on the renderer side. This is because the renderer temporarily stores the blob data while it waits for the browser to request it.

Using a different store would possibly help you with this issue; something like the indexeddb-chunk-store.

Hope this helps.
