A simple database for Node.js, using a single flat file as the storage medium.
The goal is to provide a simple, lightweight, and fast key value store that is not only easy to setup but also small in size and fast.
In this article, we will see how we can use Simple-DB to store our data in the database. The data will be stored in the local filesystem of your computer and you can use it as a local cache or persist them on the cloud (Amazon S3).
Simple Database For Node Js
NodeJS JSON Database is a simple, lightweight and fast NoSQL database. It is written in JavaScript and uses the same API as node-sqlite3.
It provides all the features you would expect from a modern key/value store: atomic updates, transactions, global secondary indexes, query planning and more.
The project aims to provide a simple interface to store and retrieve data, while providing efficient performance and the ability to handle complex queries.
If you want to use it as an embedded database for your web application, check out the web demo or the example below.
SQLite is a relational database management system contained in a C library, which interfaces with the host system’s built-in SQLite client API.
SQLite is ACID-compliant and implements most of the SQL standard, using the same engine as MySQL but without the MySQL server. SQLite is public domain software.
SQLite is an embedded relational database that does not require a separate server process and acts as a lightweight alternative to larger DBMSs. It is included in macOS and iOS, and available for Windows and Linux/POSIX systems such as Android or Ubuntu Touch.
nodejs sqlite
A NodeJS library that implements a subset of the MongoDB API (our fork). This includes support for queries, indexing, transactions, etc. The goal of this project is to have 100% compatibility with MongoDB API so that all existing code can be used with minimum changes needed.
Node.js is a server side programming language that is capable of running on the back end of client-side applications. This allows developers to create web apps that are capable of communicating with each other, and it also allows for the creation of desktop apps.
Node.js is built on top of Google’s V8 JavaScript engine, which means that it has access to all the same features as JavaScript, such as built-in objects and syntax.
In this article we will cover some simple databases for Node.js developers.
Simple Database For Node Js: SQLite
SQLite is an in-process library that implements a self-contained, serverless, zero-configuration, transactional SQL database engine. It is free and open source software released under the BSD license. While SQLite is not a client/server database like MySQL or PostgreSQL, it can be used as the backing store for web applications when combined with an application server such as Apache or nginx (as well as other non-web servers).
Here are some of the best SQLite3 databases for Node.js:
node-sqlite3, a simple and easy to use wrapper for sqlite3.
node-sqlite, a pure JavaScript port of SQLite, which allows you to store data on the client side without having to send it to a server.
node-inmemory, an in-memory key/value database for Node.js and the browser. It supports transactions, callbacks and index creation/updates etc. It also has support for storing binary data such as images!
db-sqlite3, an extension of node-sqlite3 that adds support for SQL queries on top of it. In addition to that it also supports multiple connections at the same time using different dialects (MySQL, Sqlite).
An in-memory database for testing.
A simple NoSQL database for NodeJS & the browser.
Simple JSON database with an API designed to be flexible and easy to use.
A powerful, scalable, high performance, open source NoSQL datastore.
Lightweight and fast, with a built-in HTTP server for your data.
Node.js in memory database for testing is a lightweight, easy to use, and fast NoSQL database. It is based on LevelDB, a key-value store built by Google, and written in C++. LevelDB stores data in a tree structure, making it extremely efficient for reading and writing large sets of data.
The database is intended for small datasets (under 1GB). For larger datasets, we recommend using MongoDB or Redis.
Demo: https://github.com/NodeJS/node-levelup
Installation: npm install levelup
Example: var levelup = require(‘levelup’); var db = levelup(‘./mydb’, {name: ‘mydb’}); db.put(‘name’, ‘foo’); db[‘name’] === ‘foo’;
Node.js is a JavaScript runtime environment built on Chrome’s V8 JavaScript engine. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient. It’s perfect for data-intensive real-time applications that run across distributed devices.
The content of this tutorial is based on the following module:
NodeJs – In Memory Database (MongoDB)
In this article we will talk about how to use a database in NodeJS, and what are the different databases that are available for NodeJS like SQLite3, MongoDB, PostgreSQL etc…
The most common databases used in Node.js applications are SQLite and MongoDB.
SQLite is a flat file database, which means it doesn’t have a pre-defined schema, and there’s no need to install a database server. It’s lightweight and easy to use.
MongoDB is an open source document-oriented database that uses JSON-like documents with dynamic schemas.
Node.js is a platform built on Chrome’s JavaScript runtime for easily building fast, scalable network applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.
Node.js has been gaining popularity as a web development technology in recent years. In fact, it’s the most popular server-side technology used on the web today according to the 2018 Stack Overflow Survey. Its popularity can be attributed to how easy it is to use and how quickly you can get results by using it for your projects. It’s much easier to learn than other technologies like PHP or Ruby on Rails, so developers don’t have to spend as much time studying before they can get started with real projects.
There are lots of reasons why so many people are choosing NodeJS over other programming languages:
It’s quick & easy – NodeJS uses Javascript which makes it very simple & easy to learn and use!
It’s scalable – You can use NodeJS to build large scale apps with millions of users without any problems!
It runs on multiple platforms – You can run your app on Windows, Mac OSX or Linux without any problem!
A database is a structured collection of data. Databases are used to store and retrieve large amounts of information, and they can be used to create reports and analyses.
The most popular database systems are SQLite, MySQL, PostgreSQL, MongoDB and Redis.
SQLite is a file-based database system that can be embedded in applications or run on the desktop. It is lightweight, easy to use, self-contained and runs everywhere. SQLite has many of the features of a large server-side database system but in a small package that can be embedded in an application or run on an ordinary desktop computer.
MySQL/MariaDB are open source relational database management systems (RDBMS). They are multi-user capable databases that provide high availability through clustering technology, as well as having strong security features such as auditing, encryption and user authentication via SSL/TLS connections.
PostgreSQL is an object-relational database management system (ORDBMS) with an emphasis on extensibility and standards compliance. It has been developed since 1986 by Berkeley Software Design, Inc., now known as Sleepycat Software; it was acquired by Oracle Corporation in 2007.[4] The PostgreSQL community consists of a large number of contributors from organizations.
