Maokai

Experimental, you have been warned.

npm install maokai

Experimental in-memory database for NodeJS that journals mutations/changes to disk and repeats them on load to restore the model to previous state. It also supports in-memory transaction of sorts, see kernel.js and it's usage of proxywrapper.js

Currently there is one function available named execute and it's Promise-based. It works for both commands and queries and detects when a operation changes the model with the help of proxywrapper.js, only changes are journaled to disk.

const Maokai = require('maokai');

const configuration = {
      path: './test/temp/',
      readonlyJournal: false,
      forceNewJournal: false
    };

const core = new Maokai(configuration);

// Update/Insert, second parameter is what should be supplied as data
// to the function passed in the first parameter
core.execute((model, data) => model.name = data, "CodeDux");

// You can also return data
core.execute((model) => { return model.name; })
  .then((result) => {/* Do something with the result */});
// Or as part of changes
core.execute((model, data) => {
    model.name = data;
    return model.age;
  }, "CodeDux").then((result) => {/* Do something with the result */});
