nfdb

nfdb

terribly simplistic kv store for local fs

nfdb

creates a namespace (object) that will be written to disc (and read from disc upon start).

const nfdb = require('nfdb').nfdb;

var myLocalJsonFileStore = nfdb(
  'engagedUserList',                                    // name of the db
  process.cwd() + '/data/engagedUserList.ndfb.json',    // file to save the data in
  {
    saveOnWrite: false,                                 // save data on every data change (this is slow as it's sync and uses JSON.stringify)
    saveInterval: 30000                                 // (additionally) save every X milliseconds .. 
  }
);


myLocalJsonFileStore.set(
  'usernames',
  [
    'user1',
    'user2'
  ]
);

var un = myLocalJsonFileStore.get(
  'usernames'
);

## persists

persists will monitor changes to an object/array and persists that single object to disc

const persists = require('nfdb').persists;

var pArray1 = persists( 'Array', // works for Array and Object .. fallback is an Object 'pArray1', // name ... currently only used for events './pArray1.persist.json', // filepath for saving { //options .. saveOnChange: true, // each change is written to disc saveInterval: null, // a write to disc interval in ms loadOnInit: true, // load 'old' data from the filepath (if it exists) events: null, // if an event-emitter is given, any change will trigger a name + '_change' event and a discwrite a name +'_fswrite' event } );

// NOTE ... re-initializing the persists object will lose all 'watch' effects.
