What is RxJS

Reactive Extensions for JavaScript (RxJS) is a precise alternative for callback or Promise-based libraries. It treats any ubiquitous source of events in the exact same manner, whether it is reading a file, making an HTTP call, clicking a button, or moving the mouse. RxJS is built on top of the pillars of functional and reactive programming, as well as a few popular design patterns such as Observer and Iterator.

Way to integrate RxJS with Vue

Technology

– Vue 2.5
– RxJS 6
– Vue-Rx 6

Install RxJS & Vue-Rx plugin

First, we need to install RxJS and Vue-Rx in our Vue App.
Run command: npm install rxjs vue-rx

Add Vue-Rx plugin to Vue instance

Now we use the Vue-Rx plugin with Vue.use(). It makes an internal call to the plugin’s install() method
Open src/main.js:

Vue.use(VueRx, RxJS) tells Vue to use the Vue-Rx plugin with the entire RxJS library. We can only import what we need to reduce bundle size:

Use RxJS in Vue App

Now we can use RxJS inside of Vue application. Open App.vue, import necessary modules from RxJS:

Then create an Observable data stream:

Now we declare our subscriptions as a function:

The subscriptions() function return unique observables for each component instance:

integrate-rxjs-vue-rx-observables

Display the results

We can use v-for directive to iterate over the array and display the results:

integrate-rxjs-vue-rx-results

Source Code

integrate-vue-rxjs-example

Commands to run:
npm install
npm run dev
