What's Reactive Programming Libraries?

RxJS (Reactive Extensions for JavaScript) is a library for composing asynchronous and event-based programs using observable sequences. It provides a powerful way to work with asynchronous data streams, enabling developers to manage events, asynchronous calls, and data transformations in a declarative manner. RxJS-compat is a compatibility layer that allows developers to migrate from RxJS version 5 to version 6 without having to refactor their existing code immediately. It provides the same API as RxJS 5, making it easier to transition to the newer version while maintaining existing functionality.

Feature Comparison: rxjs vs rxjs-compat

API Design

  • rxjs:

    RxJS offers a rich set of operators and a more modular approach to handling asynchronous data streams. It introduces a new way of composing operations using pipeable operators, which can be more efficient and easier to read compared to the previous version.

  • rxjs-compat:

    RxJS-compat maintains the API of RxJS 5, allowing developers to use the same operators and methods without modification. This makes it easier for teams to transition without needing to rewrite their existing code immediately.

Performance

  • rxjs:

    RxJS 6 introduces performance optimizations, including better tree-shaking capabilities, which help reduce the final bundle size by allowing unused code to be eliminated during the build process. This results in faster load times and improved application performance.

  • rxjs-compat:

    While RxJS-compat allows for backward compatibility, it does not include the performance enhancements of RxJS 6. Using rxjs-compat may lead to larger bundle sizes and slower performance compared to using the latest RxJS.

Learning Curve

  • rxjs:

    RxJS has a steeper learning curve due to its extensive set of operators and concepts like Observables, Subjects, and Schedulers. However, mastering these concepts can significantly enhance a developer's ability to manage complex asynchronous workflows effectively.

  • rxjs-compat:

    RxJS-compat is easier for developers familiar with RxJS 5, as it allows them to continue using the same patterns and practices without needing to learn the new API immediately. This can ease the transition for teams with existing codebases.

Community and Support

  • rxjs:

    RxJS has a large and active community, with extensive documentation, tutorials, and resources available. This support makes it easier for developers to find solutions to problems and learn best practices.

  • rxjs-compat:

    RxJS-compat, while useful for migration, is not actively developed and may not receive the same level of community support as RxJS. Developers are encouraged to transition to RxJS for long-term support and updates.

Future-Proofing

  • rxjs:

    Using RxJS ensures that your application is built on the latest standards and features, making it more adaptable to future changes in the ecosystem. It is actively maintained and updated, ensuring compatibility with new JavaScript features and frameworks.

  • rxjs-compat:

    RxJS-compat is intended as a temporary solution for migration. Relying on it for the long term may hinder your application's ability to leverage new features and improvements available in RxJS.

How to Choose: rxjs vs rxjs-compat
  • rxjs:

    Choose RxJS if you are starting a new project or if you want to take advantage of the latest features and performance improvements. RxJS provides a more modern API and better support for tree-shaking, which can help reduce bundle size.

  • rxjs-compat:

    Choose RxJS-compat if you have an existing codebase that relies on RxJS 5 and you need to upgrade to RxJS 6 gradually. It allows you to maintain your current code while you refactor it to use the new RxJS 6 API.

Similar Npm Packages to rxjs

rwxjs is a powerful library for reactive programming using Observables, making it easier to compose asynchronous or callback-based code. It provides a robust set of operators to handle events, asynchronous data streams, and more, allowing developers to manage complex data flows in a clean and efficient manner. While rxjs is a popular choice for reactive programming, there are alternatives that can also help with similar tasks. Here are a couple of alternatives:

  • lodash is a widely-used utility library that provides a variety of functions for common programming tasks, such as manipulating arrays, objects, and strings. While lodash is not specifically designed for reactive programming, it offers a rich set of utilities that can simplify data manipulation and enhance productivity in JavaScript applications. If your project requires extensive data manipulation and you prefer a more functional programming style, lodash can be a great complement to rxjs or even a standalone solution for simpler use cases.

  • rxjs-compat is a compatibility layer that allows developers to migrate from older versions of rxjs to the latest version without breaking existing code. It provides a bridge for using deprecated operators and features that were part of previous rxjs versions. If you are maintaining a legacy codebase that relies on older rxjs functionality, using rxjs-compat can help ease the transition to the latest version while still leveraging the benefits of reactive programming.

Similar Npm Packages to rxjs-compat

rxjs-compat is a compatibility layer for RxJS, designed to help developers transition from RxJS version 5 to version 6. It provides a way to use the older RxJS 5 APIs while migrating to the newer version, allowing for a smoother upgrade path without breaking existing codebases. This package is particularly useful for projects that rely heavily on RxJS 5 and need to gradually adopt the newer features and improvements introduced in RxJS 6.

The primary alternative to rxjs-compat is rxjs, which is the latest version of the Reactive Extensions for JavaScript. RxJS is a powerful library for reactive programming using Observables, allowing developers to compose asynchronous and event-based programs using operators. RxJS 6 introduced several improvements, including a more modular approach, better performance, and a new pipeable operator syntax. While rxjs-compat is helpful for legacy code, using the latest version of RxJS is recommended for new projects or when fully migrating existing applications, as it provides the latest features and optimizations.

The Roadmap from RxJS 7 to 8

Curious what's next for RxJS? Follow along with Issue 6367.

RxJS 7

FOR 6.X PLEASE GO TO THE 6.x BRANCH

Reactive Extensions Library for JavaScript. This is a rewrite of Reactive-Extensions/RxJS and is the latest production-ready version of RxJS. This rewrite is meant to have better performance, better modularity, better debuggable call stacks, while staying mostly backwards compatible, with some breaking changes that reduce the API surface.

Versions In This Repository

  • master - This is all of the current work, which is against v7 of RxJS right now
  • 6.x - This is the branch for version 6.X

Most PRs should be made to master.

Installation and Usage

ES6 via npm

npm install rxjs

It's recommended to pull in the Observable creation methods you need directly from 'rxjs' as shown below with range. If you're using RxJS version 7.2 or above, you can pull in any operator you need from the same spot, 'rxjs'.

import { range, filter, map } from 'rxjs';

range(1, 200)
  .pipe(
    filter(x => x % 2 === 1),
    map(x => x + x)
  )
  .subscribe(x => console.log(x));

If you're using RxJS version below 7.2, you can pull in any operator you need from one spot, under 'rxjs/operators'.

import { range } from 'rxjs';
import { filter, map } from 'rxjs/operators';

range(1, 200)
  .pipe(
    filter(x => x % 2 === 1),
    map(x => x + x)
  )
  .subscribe(x => console.log(x));

CDN

For CDN, you can use unpkg:

https://unpkg.com/rxjs@^7/dist/bundles/rxjs.umd.min.js

The global namespace for rxjs is rxjs:

const { range } = rxjs;
const { filter, map } = rxjs.operators;

range(1, 200)
  .pipe(
    filter(x => x % 2 === 1),
    map(x => x + x)
  )
  .subscribe(x => console.log(x));

Goals

  • Smaller overall bundles sizes
  • Provide better performance than preceding versions of RxJS
  • To model/follow the Observable Spec Proposal to the observable
  • Provide more modular file structure in a variety of formats
  • Provide more debuggable call stacks than preceding versions of RxJS
