Atomic find-or-create plugin for mongoose
npm install find-or-create-mongooseA findOrCreate plugin that's atomic). A necessary characteristic for use in scaled, distributed systems. Achieved by reducing the findOrCreate determination to a single mongo operation.
#### You can set the plugin on the mongoose instance:
``
// app.js
const mongoose = require('mongoose');
const findOrCreate = requir ('find-or-create-mongoose');
mongoose.plugin(findOrCreate);
#### Or on individual schemas:
`
// people.model.js
const findOrCreate = require('find-or-create-mongoose');
const schema = new mongoose.Schema({
name: { type: String },
age: { type: Number }
});
schema.plugin(findOrCreate);
module.exports = mongoose.model('People', schema, 'people');
`
#### Then use it ...
`
// people.controller.js
const findBy = { name: 'John' };
const onCreate = { name: 'John', age: 29 };
const result = await model.findOrCreate(findBy, onCreate);
/*
* result === {
* writeResult: 'create' / 'find',
* document: { THE_MONGO_RECORD }
* }
**/
