mongqee v1.0.0

Mongqee

Mongqee is a query language that translate into mongodb filter. What I want to achieve is to be able to parse it directly using mongoose for examle

const mongqee = require("mongqee");
//... rest of import

// parse a query
const query = `Customer.age > 40 AND customer.address LIKE "Jakarta"`;
const filter = mongqee.parse(query);
// this would parse into
// {
//   "$and": [
//     {
//       "Customer.age": {
//         "$gt": 40
//       }
//     },
//     {
//       "customer.address": {
//         "$eq": new Regexp('Jakarta', 'gim')
//       }
//     }
//   ]
// }
// then you can use it directly inside mongo
const customers = await Customer.find(filter);

// it also support grouping query
const query2 = `(Customer.age > 40 AND customer.address LIKE "Jakarta") or 
                (Customer.type = 'vvip' and customer.attempt > 5)`;
const filter = mongqee.parse(query2);
//  will parse into
// {
//   "$or": [
//     {
//       "$and": [
//         {
//           "Customer.age": {
//             "$gt": 40
//           }
//         },
//         {
//           "customer.address": {
//             "$eq": new Regexp('Jakarta', 'gim')
//           }
//         }
//       ]
//     },
//     {
//       "$and": [
//         {
//           "Customer.type": {
//             "$eq": "vvip"
//           }
//         },
//         {
//           "customer.attempt": {
//             "$gt": 5
//           }
//         }
//       ]
//     }
//   ]
// }

Roadmap

• basic query
• combining query with filter:
• • AND filter
• • OR filter
• Add more non-primitive (>, < , >=, etc):
• • LIKE operand
• Grouping Query with parentheses
• conditional (IF)
• aggregate function (SUM, AVERAGE) ?
