A Lightweight Disk based JSON Database with a MongoDB like API for Node.You will never know that you are interacting with a File SystemContentsGetting StartedDocumentationConnectLoad CollectionsWrite/SaveReadUpdateRemoveCountExamplesPerformanceContributingRelease HistoryGetting StartedInstall the module locally :var db = require('diskdb');db = db.connect('/path/to/db-folder', ['collection-name']);// you can access the traditional JSON DB methods hereDocumentationConnect to DBdb.connect(pathToFolder, ['filename']);Filename will be the name of the JSON file. You can omit the extension, diskDB will take care of it for you.var db = require('diskdb');db = db.connect('/examples/db', ['articles']);// or simplydb.connect('/examples/db', ['articles']);This will check for a directory at given path, if it does not exits, diskDB will throw an error and exit.If the directory exists but the file/collection does not exist, diskDB will create it for you.Note : If you have manually created a JSON file, please make sure it contains a valid JSON array, otherwise diskDBwill return an empty array.Else it will throw an error likeundefined:0^SyntaxError: Unexpected end of inputLoad CollectionsAlternatively you can also load collections likevar db = require('diskdb');// thisdb = db.connect('/examples/db');db.loadCollections(['articles']);//ordb.connect('/examples/db');db.loadCollections(['articles']);//ordb.connect('/examples/db') .loadCollections(['articles']);//ordb.connect('/examples/db', ['articles']);Load Multiple Collectionsvar db = require('diskdb');db.connect('/examples/db', ['articles','comments','users']);Write/Save to Collectiondb.collectionName.save(object);Once you have loaded a collection, you can access the collection's methods using the dot notation likedb.[collectionName].[methodname]To save the data, you can usevar db = require('diskdb');db.connect('db', ['articles']);var article = { title : "diskDB rocks", published : "today", rating : "5 stars"}db.articles.save(article);// ordb.articles.save([article]);The saved data will be[ { "title": "diskDB rocks", "published": "today", "rating": "5 stars", "_id": "0f6047c6c69149f0be0c8f5943be91be" }]You can also save multiple objects at once likevar db = require('diskdb');db.connect('db', ['articles']);var article1 = { title : 'diskDB rocks', published : 'today', rating : '5 stars'}var article2 = { title : 'diskDB rocks', published : 'yesterday', rating : '5 stars'}var article3 = { title : 'diskDB rocks', published : 'today', rating : '4 stars'}db.articles.save([article1, article2, article3]);And this will return the inserted objects[ { title: 'diskDB rocks', published: 'today', rating: '4 stars', _id: 'b1cdbb3525b84e8c822fc78896d0ca7b' }, { title: 'diskDB rocks', published: 'yesterday', rating: '5 stars', _id: '42997c62e1714e9f9d88bf3b87901f3b' }, { title: 'diskDB rocks', published: 'today', rating: '5 stars', _id: '4ca1c1597ddc4020bc41b4418e7a568e' } ]Read from CollectionThere are 2 methods available for reading the JSON collectiondb.collectionName.find(query)db.collectionName.findOne(query)db.collectionName.find()var db = require('diskdb');db.connect('/examples/db', ['articles']);db.articles.find();This will return all the records[{ title: 'diskDB

Rocks', published: 'today', rating: '5 stars', _id: '0f6047c6c69149f0be0c8f5943be91be'}]You can also query with a criteria likevar db = require('diskdb');db.connect('/examples/db', ['articles']);db.articles.find({rating : "5 stars"});This will return all the articles which have a rating of 5.Find can take multiple criteriavar db = require('diskdb');db.connect('/examples/db', ['articles']);db.articles.find({rating : "5 stars", published: "yesterday"});This will return all the articles with a rating of 5, published yesterday.Nested JSON :var articleComments = { title: 'diskDB rocks', published: '2 days ago', comments: [{ name: 'a user', comment: 'this is cool', rating: 2 }, { name: 'b user', comment: 'this is ratchet', rating: 3 }, { name: 'c user', comment: 'this is awesome', rating: 2 }]}var savedArticle = db.articles.save([articleComments);foundArticles = db.articles.find({rating : 2});Since diskDB is mostly for light weight data storage, avoid nested structures and huge datasets.db.collectionName.findOne(query)var db = require('diskdb');db.connect('/examples/db', ['articles']);db.articles.findOne();If you do not pass a query, diskDB will return the first article in the collection. If you pass a query, it will return first article in the filtered data.var db = require('diskdb');db.connect('/examples/db', ['articles']);db.articles.findOne({_id: '0f6047c6c69149f0be0c8f5943be91be'});Update Collectiondb.collectionName.update(query, data, options);You can also update one or many objects in the collectionoptions = { multi: false, // update multiple - default false upsert: false // if object is not found, add it (update-insert) - default false}Usagevar db = require('diskdb');db.connect('/examples/db', ['articles']);var query = { title : 'diskDB rocks'};var dataToBeUpdate = { title : 'diskDB rocks again!',};var options = { multi: false, upsert: false};var updated = db.articles.update(query, dataToBeUpdate, options);console.log(updated); // { updated: 1, inserted: 0 }Remove Collectiondb.collectionName.remove(query, multi);You can remove the entire collection (including the file) or you can remove the matched objects by passing in a query. When you pass a query, you can either delete all the matched objects or only the first one by passing multi as false. The default value of multi is true.var db = require('diskdb');db.connect('/examples/db', ['articles']);db.articles.remove({rating : "5 stars"});var db = require('diskdb');db.connect('/examples/db', ['articles']);db.articles.remove({rating : "5 stars"}, true); // remove all matched. Default - multi = truevar db = require('diskdb');db.connect('/examples/db', ['articles']);db.articles.remove({rating : "5 stars"}, false); // remove only the first matchUsing remove without any params will delete the file and will remove the db instance.var db = require('diskdb');db.connect('/examples/db', ['articles']);db.articles.remove();After the above operation db.articles
