To import only what you need by patching (this is useful for size-sensitive bundling):

To import what you need and use it with proposed bind operator:

Note: This additional syntax requires transpiler support and this syntax may be completely withdrawn from TC39 without notice! Use at your own risk.

CommonJS via npm

Import all core functionality:

Import only what you need and patch Observable (this is useful in size-sensitive bundling scenarios):

Import operators and use them manually you can do the following (this is also useful for bundling):

You can also use the above method to build your own Observable and export it from your own module.

CommonJS with TypeScript

If you recieve an error like or when using RxJS you may need to install a supplemental set of typings.

RxJS - Latest Updates



We are using RxJS version 6 in this tutorial. RxJS is commonly used to deal with reactive programming and used more often with Angular, ReactJS. Angular 6 loads rxjs6 by default.

RxJS version 5 was handled differently in comparison to version 6. The code will break in case you update your RxJS 5 to 6. In this chapter, we are going to see the difference in ways of handling the version update.

In case you are updating RxJS to 6 and don't want to make the code changes, you can do that too, and will have to install the following package.

npm install --save-dev rxjs-compact

This package will take care of providing backward compatibility and old code will work fine with RxJS version 6. If you want to make the code changes that works fine with RxJS 6, here are the changes that needs to be done.

The packages for operators, observables, subject were restructured and hence, the major changes go in for imports and they are explained below.

Imports for operators

As per version 5, for operators the following import statements should be included −

import 'rxjs/add/operator/mapTo' import 'rxjs/add/operator/take' import 'rxjs/add/operator/tap' import 'rxjs/add/operator/map'

In RxJS version 6 the imports will be as follows −

import {mapTo, take, tap, map} from "rxjs/operators"

Import of Methods to create Observables

As per version 5, while working with Observables, the following import methods should be included −

import "rxjs/add/observable/from"; import "rxjs/add/observable/of"; import "rxjs/add/observable/fromEvent"; import "rxjs/add/observable/interval";

In RxJS version 6 the imports will be as follows −

import {from, of, fromEvent, interval} from 'rxjs';

Import of Observables

In RxJS version 5, while working with Observables, the following import statements should be included −

import { Observable } from 'rxjs/Observable'

In RxJS version 6, the imports will be as follows −

import { Observable } from 'rxjs'

Import of Subject

In RxJS version 5, subject should be included as follows −

import { Subject} from 'rxjs/Subject'

In RxJS version 6, the imports will be as follows −

import { Subject } from 'rxjs'

How to use operators in RxJS 6?

pipe() method is available on the observable created. It is added to RxJS from version 5.5. Using pipe() now you can work on multiple operators together in sequential order. This is how the operators were used in RxJS version 5.

Example

import "rxjs/add/observable/from"; import 'rxjs/add/operator/max' let list1 = [1, 6, 15, 10, 58, 2, 40]; from(list1).max((a,b)=>a-b).subscribe(x => console.log("The Max value is "+x));

From RxJS version 5.5 onwards, we have to use pipe() to execute the operator −

Example

import { from } from 'rxjs'; import { max } from 'rxjs/operators'; from(list1).pipe(max((a,b)=>a-b)).subscribe(x => console.log( "The Max value is "+x) );

Operators Renamed

During restructuring of the packages some of the operators were renamed as they were conflicting or matching with javascript keywords. The list is as shown below −

OperatorRenamed to
do()tap()
catch()catchError()
switch()switchAll()
finally()finalize()
throw()throwError()

Right way to upgrade RxJS to latest version?

EDIT 2020

The easiest way to force upgrade any package would be to do append an to the required package.

In our use case it would be

This would force your current setup to install the latest stable version available.

Bear in mind that the latest version might not always be compatible with all the libraries in use. In case a specific range is needed due to compatibility issues you should install specific versions(e.g for the use case)

In the previous answer it was also included the -g flag. This would (as for any npm package installation) install the specified package globally in your system and not only on the current project

Previous Answer

You can always try to force the version by doing

Or you can have a more modern approach and use yarn :)

NOTE

Since the release of npm 5.x the comment about yarn is no longer necessarily true :)

RxJS Latest Release Updates

next →← prev

The latest version of RxJS is v6. It is version 6, which is released recently, and we are doing this tutorial in RxJS version 6. We know that RxJS is used to deal with reactive programming. It is common and most often used with Angular and ReactJS. Angular 6 loads rxjs6 by default.

Why update RxJS Version 6?

RxJS v6 is the major version change from RxJS 5.x to RxJS 6.x. The developers have done a lot of work to keep the hard breaking changes to a minimum as usual. In most cases, this allows application and library developers to update incrementally and use RxJS v6 without any modifications to their code. But, RxJS version 5 was handled differently in comparison to RxJS version 6. The code will break if you update your RxJS 5 to 6.

How to update RxJS v5 to RxJS v6 efficiently?

The backward-compatibility layer makes the update process easy and allows you to keep your apps working without failure while making changes in your code. This complete process is carried out in the following stages.

Here, we will see the different ways of handling the version update:

  • Update to the latest version of RxJS 5.5 and fix all issues caused by bug fixes.
  • Install RxJS v6 along with the backward-compatibility package, by using the command rxjs-compact.
  • If your app faces problems and the breaking changes are not covered by rxjs-compat, then update the affected code according to the instructions provided below.
  • Drop the compatibility layer to complete the update to RxJS v6. By doing this, it will significantly decrease the size of your apps.
  • Use the rxjs-tslint command to refactor the TypeScript code so that it doesn't depend on rxjs-compat.
  • Remove and replace all the deprecated functionality before the release of RxJS v7.

If you want to update your RxJS v5 to RxJS v6 and don't want to make the code changes, you can do it by installing the following package:

After installing this package, it will take care of providing backward compatibility, and your old code will work fine with RxJS version 6.

If you want to make changes in the code that it works fine with RxJS v6, you can do the following changes. The packages for operators, observables, and subject were restructured and so you have to change them how they have import for RxJS v6 in the following way:

Changes in Imports for operators

In RxJS v5, the operators and the following import statements are included as following:

In RxJS v6, these would be import as following:

Changes in Import of Methods to create Observables

In RxJS v5, when we work with Observables, we have to import methods as following:

In RxJS v6, this would be done as following:

Changes in Import of Observables

In RxJS v5, when we work with Observables, we have to import statements as following:

In RxJS v6, this would be done as following:

Changes in Import of Subject

In RxJS v5, we have to import subjects as following:

In RxJS v6, this would be done as follows:

This is how we use the operators in RxJS version 5. See the following example. In this example, we will find out the maximum value from a list.

Example:

This example is only compatible in RxJS version 5. If you run it in RxJS v6, it will give an error. See the following image:

RxJS Latest Release Updates

The pipe() method is available in RxJS v6 when the observable is created. It is added to RxJS from version 5.5. By using this method, you can work on multiple operators together in sequential order.

From RxJS version 5.5 onwards, we have to use pipe() method to execute the operator. See how the above example will be wrtten in rxJS v6:

Output:

RxJS Latest Release Updates

You can see that it has shown the correct output.

Operators that have been renamed

During the restructuring of the packages in RxJS v6, some of the operators are renamed because they were conflicting or matching with JavaScript keywords. The following list shows those operators:

OperatorRenamed to
do()tap()
catch()catchError()
switch()switchAll()
finally()finalize()
throw()throwError()

Installation and Usage

ES6 via npm

It's recommended to pull in the Observable creation methods you need directly from as shown below with . And you can pull in any operator you need from one spot, under .

import{range}from"rxjs";import{map,filter}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/[email protected]^7/dist/bundles/rxjs.umd.min.js

The global namespace for rxjs is :

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

Building/Testing

  • build everything
  • run tests
  • run dtslint tests
