Achieve compatibility with Meteor examples

[AlekSi]

Test https://github.com/meteor/examples with FerretDB, create and link issues there.
Check that those examples use OpLog.

Examples

Beta Give feedback

1. tic-tac-toe
2. tailwindcss it doesn't rely on MongoDB
3. parties
4. nft-marketplace AFAIK it doesn't rely on MongoDB for persisting any type of data. But I am running it locally and perhaps that is a factor.
5. cordova
6. complex-todos-svelte - we could ignore sparse indexes because that seems to work, sparse indexes offer performance AFAIK, see here.
7. chakra-ui it's a UI so the example doesn't require MongoDB AFAIK, I asked here for a project that could be useful for testing.
8. https://simpletasks.meteorapp.com/ (not techncially an example) a project created by a user from the meteor slack channel, we are compatible if we exclude Support partial indexes (partialFilterExpression, sparse) #2448.

Sounds good!

We are basically compatible with the blaze tutorial if we exclude #2448. This tutorial is what https://github.com/wreiske/meteor-ferretdb is pulling from.

To test it I ignored sparse indexes and it worked.

It doesn't seem to be using the $ projection operator to refresh user tokens, so I don't get logged out of the session. But I still see the below error:

If you really want to stress test out Meteor and MongoDB integration, I suggest using my old meteor-peerdb test suite. It has managed to find issues with Meteor implementation itself. :-)

thanks @mitar, we will check it out!

We just released a new version with OpLog tailing support, which was a major blocker for supporting Meteor apps: https://github.com/FerretDB/FerretDB/releases/tag/v1.18.0
