mongodb-connection-string-url
Advanced tools
The mongodb-connection-string-url npm package is designed to parse and manipulate MongoDB connection strings according to the MongoDB connection string specification. It provides a convenient way to work with MongoDB connection strings, allowing users to easily read, modify, and construct connection strings in a programmatic way.
Parsing a MongoDB connection string
This feature allows you to parse a MongoDB connection string and access its components, such as hosts, database name, and options.
"const { ConnectionString } = require('mongodb-connection-string-url');\nconst connectionString = new ConnectionString('mongodb://localhost:27017');\nconsole.log(connectionString.hosts); // Outputs: ['localhost:27017']"
Modifying the database name
This feature demonstrates how to modify the database name in a MongoDB connection string using the package.
"const { ConnectionString } = require('mongodb-connection-string-url');\nconst connectionString = new ConnectionString('mongodb://localhost:27017/mydatabase');\nconnectionString.pathname = '/anotherdatabase';\nconsole.log(connectionString.toString()); // Outputs: 'mongodb://localhost:27017/anotherdatabase'"
Adding query parameters
This feature shows how to add query parameters to a MongoDB connection string, which can be used to specify options such as retryWrites.
"const { ConnectionString } = require('mongodb-connection-string-url');\nconst connectionString = new ConnectionString('mongodb://localhost:27017');\nconnectionString.searchParams.set('retryWrites', 'true');\nconsole.log(connectionString.toString()); // Outputs: 'mongodb://localhost:27017/?retryWrites=true'"
The mongodb-uri package is similar in that it also provides functionality for parsing and formatting MongoDB URIs. However, mongodb-connection-string-url offers a more modern API and additional capabilities for manipulating the connection string components directly.
While connection-string is a more general-purpose package for parsing and building connection strings, not limited to MongoDB, mongodb-connection-string-url is specifically tailored for MongoDB connection strings, providing more specialized functionality in that context.
MongoDB connection strings, based on the WhatWG URL API

const cs = new ConnectionString('mongodb://localhost');
cs.searchParams.set('readPreference', 'secondary');
console.log(cs.href); // 'mongodb://localhost/?readPreference=secondary'
