Thank you.

This needs to be reverted. Buffer is not defined in browser settings, so this change effectively breaks Proto2TypeScript for non-Node environments.

[kalbasit]

Not sure reverting is the right solution here as I only brought the library up to date. Should we source the definition of Buffer instead?

[tamird]

No, that would not be correct in non-Node environments.

Note that encodeNB throws in non-Node environments, so it is not expected to be usable from a browser.

[kalbasit]

@tamird true but again, this repo provides the TD of a protobuf, it does not assume NodeJS or Browser. So perhaps we could add a flag to enable node-only definitions?

@yellowiscool we should add node-only and browser-only tests to this repo?

[fungiboletus]

I don't know whether we should revert the commit. The "master" branch has never been very stable.

But we should definitely fix that. The flag to enable the node-only definitions is a good idea. The tests could also be improved, they were develop when I was the single user of the project, and they are far from perfect.
