Does the library provide any built-in mechanism for handling rate limits? If not, what is the recommended way to handle it?

👋 this not part of the library as it is more of a server concern than the graphql concern

If you wanted to do rate limiting by field you can create a custom directive but then it will be up to you to write the logic still to determine who is calling and how much they have called already. A lot of solutions in the JS ecosystem use Redis to keep that info in sync across instances
