Found that https://github.com/anywhichway/proxy-observe , but seem too heavy

[domguinard]

Thanks franckOL. We actually did see that this was deprecated and started experimenting with alternatives. Will report on our findings and hopefully provide a patch soon. For now, the ideal is to stick with the current Node LTS: 4.X which still supports Object.observe().

Hi,
What about the pull request, it works for all version of node js, and it's really minor change.

Sorry about that Franck, we missed the PR. This is really simple and great. I just accepted the PR, thanks a lot!

[domguinard]

Reopening as the new Node LTS is now 6 we'll be looking into this.

Running the latest commit in master as of today. Still seeing the Object.observe is not a function issue.

Hi Guys ! Any solution to this problem ? I am going through chapter 7 of webofthings, and I am stuck because of this Object.observe problem when i try to execute the wot.js

[domguinard]

Hi guys, we have tested a number of solutions but haven't found a totally nice and simple one yet, we are still working on it but meanwhile I would stick to Node 4.X which supports Object.observe(). (you can install several version of node with NVM)

Any update on this?
