![]() ![]() ![]() They are also crash-resistant, reliable, and have a small footprint. Node.js and SQLite are easy to use because they are simple, efficient, and fast due to their asynchronous I/O and the use of a single thread. ![]() With Node.js and SQLite, you can quickly build lightweight, fast, and reliable applications. SQLite is a self-contained, high-reliability, embedded, full-featured, public-domain SQL database engine. Node.js is an open-source, cross-platform runtime environment for developing server-side and networking applications. They can run on various platforms, making them versatile, especially in mobile development. It is easy to deployīoth Node.js and SQLite are lightweight and don’t require a lot of resources to run. It is easy to get startedīoth node.js and SQLite are open source and have a large community of developers and users. The combination of Node.js and SQLite is popular because it provides a fast and efficient way to build web applications. Therefore, it is easy to develop applications using data from an SQLite database without connecting to a separate database server. The two technologies work well together because developers can easily embed SQLite databases within a Node.js application. SQLite is a lightweight, self-contained database popular for its ease of use and portability. In this tutorial, you have learned how to connect to an SQLite database either in-memory or disk file based is a JavaScript runtime environment that allows you to build server-side applications. Note that you will learn how to query data in the next tutorial. So you now can open an SQLite database and provide the detailed information if an error occurred as follows: let db = new sqlite3.Database( ':memory:', (err) => ) Code language: JavaScript ( javascript ) In case the database is opened successfully, the open event is emitted regardless of whether a callback is provided or not. If you don’t provide the callback function and an error occurred during opening the database, an error event will be emitted. If an error occurred, the error object is not null, otherwise, it is null. The callback function has the error object as the first parameter. The sqlite3.Database() accepts a callback function that will be called when the database opened successfully or when an error occurred. The sqlite3.Database() returns a Database object and opens the database connection automatically. Second, create a Database object: let db = new sqlite3.Database( ':memory:') Code language: JavaScript ( javascript ) Notice that the execution mode is set to verbose to produce long stack traces. ![]() To open a database connection to an in-memory database, you use the following steps.įirst, import the sqlite3 module: const sqlite3 = require( 'sqlite3').verbose() Code language: JavaScript ( javascript ) Second, call the Database() function of the sqlite3 module and pass the database information such as database file, opening mode, and a callback function.To connect to an SQLite database, you need to: You can use npm to do so using the following command: > npm install sqlite3 Code language: JavaScript ( javascript )Īfter installing the sqlite3 module, you are ready to connect to an SQLite database from a Node.js application. To interact with the SQLite database, you need to download and install sqlite3 module. Summary: in this tutorial, you will learn how to connect to an SQLite database from Node.js applications. ![]()
