This is very useful IMO. We had to manually do this ourselves.

I found this problem to check permissions on CLP so i decide share my solutions, this is based on ACL.
Just to sumarize my approach (similar to basic vs advanced on parse-dashboard):
write access = update && create && delete && addField access
read access = find && count && get access

[JeromeDeLeon]

Haven't look it up thoroughly.

@brunocosta91 thanks for the PR. It is a great job! I have some questions:

• Would it be possible to also support requiresAuthentication and pointer permissions? @dplewis @acinader am I missing something else?
• Could you provide an example on how it will integrate with the other functions we have here in the SDK? I mean, how would we use the ParseCLP object and setup the CLP of a certain class?
• Could you please increase the test coverage? Only 50% of the ParseCLP.js file is currently covered.
• It would be greate to also have a PR to the JS Docs explaining how to use it.

@davimacedo looks good to me.

[brunocosta91]

This weekend I will add more test and try improve PR with suggestions by @davimacedo

[dplewis]

@brunocosta91 Any updates on this? It would be awesome to include this in the SDK. Let us know if you need assistance.

[brunocosta91]

I will try get some time to improve this PR

[dplewis]

@brunocosta91 I can finish this PR up for you. I just need write access to your fork. This is an amazing feature!

[dplewis]

@davimacedo @mtrezza I believe this is ready for review.
