rxmetics v0.2.1

Arithmetics for RxJS observables.

npm i rxmetics

This is a minimal RxJS library for lazy people. Instead of this:

import { combineLatest, ... } from 'rxjs';
import { map, ... } from 'rxjs/operators';

// ...

combineLatest(a, b).pipe(map(([a, b]) => a + b))...

You can do this:

import { add } from 'rxmetics';

// ...

add(a, b)...

Or this:

import { add } from 'rxmetics/pipes';

// ...

a.pipe(add(b))...

But its not just for numbers (its RxJS arithmetics):

import { and, eq } from 'rxmetics';

// ...

and(a.pipe(eq(32)), b.pipe(eq('halo')))...

import { rxl } from 'rxmetics';
import { interval } from 'rxjs';

// ...

rxl`hellow ${interval(1000)}`.subscribe(console.log);

// RESULT:
// > hellow
// > hellow 1
// > hellow 2
// > hellow 3
// ...
