New Tools and Updates

Announcing Node v17

node.js v17 release
The latest major version of Node.js brings several improvements to the runtime, as well as additional promisified APIs, OpenSSL 3.0 support, and an update of the JavaScript engine to V8 9.5.

The team introduces in Node.js 17 promise-based APIs for the Readline module. It provides an interface for reading data from a Readable stream one line at a time. Besides, the new release includes OpenSSL 3.0, which provides QUIC support. However, FIPS support remains available via the new FIPS module. Follow the link to read the full list of updates.

What’s New in Gatsby 4

Gatsby is a popular open-source frontend framework that blends the functionality from React, GraphQL, and Webpack. According to the Gatsby team, the recent release is the most impactful one since it provides enhanced user experience and blazing-fast speed for end-users.

Gatsby 4 introduces two new page rendering modes, Deferred Static Generation (DSG) and Server-Side Rendering (SSR), that cut down long build time and allow developers to choose how content is generated. The release also includes support for Parallel Query Processing, which introduces a multithreaded approach and provides a 40% reduction in build times for some sites.

Having added SSR and DSG features to Gatsby Cloud, developers have to rebuild infrastructure. As a result, the team noted a significant reduction (by up to 90%) in deploy times for data-intensive websites. Moreover, Gatsby 4 includes new CMS integration APIs and support for React 18.

React Bootstrap 2.0 Release

React-Bootstrap is one of the oldest React libraries that has evolved alongside React. Each component was built from scratch in pure React, so the library can be used instead of Bootstrap JavaScript. The second major release includes full compatibility with Bootstrap 5.1 and goes under the MIT license.

Announcing TypeScript 4.5 Beta

Microsoft announced TypeScript 4.5 Beta, which comes with ECMAScript module support in Node.js, new file extensions, and a new utility type called Awaited type that was designed to help with modeling existing APIs, including JavaScript built-ins.

Besides, TypeScript 4.5 can narrow values that have template string types as well as recognize template string types as discriminants. Also, to ensure that TypeScript and JavaScript support works well out of the box, TypeScript provides a series of declaration files that represent the available APIs in the JavaScript language and the standard browser DOM APIs. Other updates include CommoJS interop, tail-recursion elimination on conditional types, disabling import elision, import assertion, and much more.
