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

Question

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?

Answer 1

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
