Installation

npm install jsonotron-memdocstore --save

Usage

To instantiate a MemDocStore you have to provide 2 parameters:

docs - An array of "documents". Each document is just a POJO.
docVersionGenerator - A function (doc) that returns a unique version number string given a document. This can be a hash based on the given document or just a unique number. Simplest method is to pass it the uuid/v4 library as this will generate a UUID.

const { createMemDocStore } = require('jsonotron-memdocstore')
const uuid = require('uuid/v4')

const docs = []
const memDocStore = createMemDocStore(docs, uuid)

memDocStore.upsert('test', {
  id: '0001',
  docType: 'test',
  hello: 'world'
})
