Question

As the title, how do I download the file of older versions.

const firstVersion: IVersion = sp.web.getFileByUrl("path/to/file").versions.getById(512); // first version
# then what?

[gomain]

This hack works

const stream = await (<IFile>firstVersion).getStream().then(res => res.body);

Is this reliable?

[patrick-rodgers]

Yes, that should be reliable. Each version points to a "file" so we could expose all the file methods on versions. Will need to do some validation to see if that is 100% true, but I think there is room to improve what we are doing for versions.

Hi +1 for adding the ability to get contents of older versions of files. I have a need to do that in a current project. (And I couldnt get gomains hack to work :-() Russell

[patrick-rodgers]

Added methods for getting content of versions to IVersion as well improved the typing of IVersionInfo to include returned fields.
