mongo-to-mysql

Convert simple mongodb queries to mysql command. See example below

We will soon be coming up with more queries with proper documentation. Stay tuned

Installation

Using npm:

$ npm i mongo-to-mysql

Usage

Insert

const MoMy = require("mongo-to-mysql")

let mongoDoc = {userName: "x", password: "y"}
let tableName = "user"
let getQuery = MoMy.insert(mongoDoc, tableName)

console.log(getQuery)
// Result: "insert into user (userName, password) values (x, y)"

Update

"$in" example:

const MoMy = require("mongo-to-mysql")

let mongoFind = {name: {$in: ["abc", "def", "ghi"]}}
let mongoUpdate = {$inc: {visits: 1}}
let tableName = "user"
let getQuery = MoMy.update(mongoFind, mongoUpdate, tableName)

console.log(getQuery)
// Result: "update user set visits = visits + 1 where name in ("abc","def","ghi")"

"$gt" example:

const MoMy = require("mongo-to-mysql")

let mongoFind = {hour: {$gt: 9}}
let mongoUpdate = {$inc: {visits: 1}}
let tableName = "user"
let getQuery = MoMy.update(mongoFind, mongoUpdate, tableName)

console.log(getQuery)
// Result: "update user set visits = visits + 1 where hour > 9"

Combined example:

const MoMy = require("mongo-to-mysql")

let mongoFind = {name: {$in: ["abc", "def", "ghi"]}, hour: {$gt: 9}}
let mongoUpdate = {$inc: {visits: 1}}
let tableName = "user"
let getQuery = MoMy.update(mongoFind, mongoUpdate, tableName)

console.log(getQuery)
// Result: "update user set visits = visits + 1 where name in ("abc","def","ghi") and hour > 9"

Multiple updates ("$inc" and "$set"):

const MoMy = require("mongo-to-mysql")

let mongoFind = {name: {$in: ["abc", "def", "ghi"]}, hour: {$gt: 9}}
let mongoUpdate = {$inc: {visits: 1}, $set: {hasVisited: 1}}
let tableName = "user"
let getQuery = MoMy.update(mongoFind, mongoUpdate, tableName)

console.log(getQuery)
// Result: "update user set visits = visits + 1, hasVisited = 1 where name in ("abc","def","ghi") and hour > 9"

Supported mongodb operations currently: "$in", "$nin", "$eq", "$ne", "$gte", "$gt", "$lte", "$lt"
