Is there such a thing as JSON schema for MongoDB query language itself?

MongoDB queries--at least in JavaScript--are structured as JSON, but it's very flexible so I am aware this wouldn't be a simple thing to do and in fact not even sure if this is possible, but was just wondering.

Is there a JSON schema to detect if a random JSON is a valid MongoDB query object?

You may validate that the structure is valid, but if you want to know if the query is actually correct, like has the right syntax and can be executed - then no, not really.

You can use something like mongodb-language-model

How to use

var accepts = require('mongodb-language-model').accepts;

console.log(accepts('{"ns":{"$in":["foo", "bar", "baz"]}}'));  // true
console.log(accepts('{"ns":{"$in":{}}}'));                     // false
console.log(accepts('{"ns":{"$regex": "foo"}}'));              // true

It seems like the MongoDB Compass has (at least partly) implemented a Query Language verification for many commands like $or, $and $text / $search etc. Compass does not simply check if your query is a valid JSON, but also validates that you provided a correct query format. If you are interested in how it has been implemented I would recommend you to check the github sourcecode.
