There’s a dizzying number of components available for building Node projects. Every type of task – from building a UI to unit testing – has multiple component solutions varying in features and complexity. For many of the most common tasks, there are several tools that stand out due to their utility, maturity, or popularity. We’ll look at these tools and how they improve the Node landscape.
React attempts to solve the problem of updating a web page’s Document Object Model (DOM) as efficiently as possible. It uses a virtual DOM to manage sections of a page as individual components, allowing you to refresh a component without refreshing the entire page. Developed by Facebook, it’s used by hundreds of projects.
Vue is a UI framework similar to React. While React is better suited for large projects, Vue is smaller and uses a simpler syntax. Vue also lets you use any valid HTML in templates, whereas React uses JSX.
Koa is a minimalist framework from the creators of Express. It makes heavy use of async/await to reduce nested callbacks and simplify code. Koa only provides a base framework and requires third-party libraries for features such as routing.
Express is one of the most popular Node.js frameworks and is used on over 250,000 websites. Like Koa, Express is billed as a minimalist framework, but it does include middleware for essential features such as routing, serving static assets, parsing JSON, and parsing URL-encoded payloads.
Bunyan is a simple JSON logger with support for customizable fields, multiple log levels, nested loggers, and multiple log streams. Bunyan also includes a CLI tool for viewing prettified log files and filtering the contents of logs.
Compared to Bunyan, Winston is a more versatile and configurable utility. You can use multiple formats including JSON, send logs to a larger variety of output streams (called transports), and log uncaught exceptions.
Axios is a Promise based HTTP client with the ability to make, intercept, transform, and cancel requests. It supports multiple concurrent requests, automatic JSON parsing, HTTP authentication, and proxies. It also supports comprehensive global configuration options which are applied to each request.
Request is a feature-rich HTTP client designed for simplicity. It supports various HTTP authentication methods, OAuth signing, Unix Domain Signing, and piping requests to and from files. While it natively uses callbacks, it provides libraries for Promise and async/await based requests.
Sequelize is a Promise based ORM supporting PostgreSQL, MS SQL, MySQL, and SQLite. As a true ORM, Sequelize lets you easily map database entries to objects and synchronize both data and schema changes. It features multiple database states, relations, eager loading, and a comprehensive querying syntax.
Knex is a Promise based query builder for PostgreSQL, MS SQL, MySQL, MariaDB, SQLite3, and Oracle databases. While it’s not a full ORM, it lets you build complex queries, pipe incoming data via streams, and track database transactions. Knex is part of the Bookshelf ORM.
Mocha is an established and widely adopted testing framework. Mocha is extremely flexible, allowing you to even choose your own assertion library. However, this does mean it requires setup and configuration before it can be used.
Developed by Facebook, Jest offers parallelized testing, snapshot testing, mocking, support for asynchronous code, and automatic test detection. Jest is a newer tool than Mocha, but it requires less configuration and runs out of the box.
