Add canonical content-length header to memos #459

Open polyrainbow opened 1 year ago

polyrainbow commented 1 year ago

As a developer working on a webapp with Noosphere integration, I want to have a way to get the file size of a file stored in a sphere, without having to "consume" and free the file by calling SphereFile.intoBytes(). To achieve this functionality, all memos referring to byte streams should have a canonical/well-known content-length header. Also, the SphereFile interface of the NPM package should have a method to return the file size, e. g. SphereFile.size().

This is important, thanks for filing it.

Content-Length will make sense for anything that we currently encode using paged BodyChunkIpld. This is almost everything except for the SphereIpld and its related substructure.

Perhaps putting it another way: any raw binary content can benefit from Content-Length, and any structured IPLD probably cannot.
