linkString Operations

String operations allow you to do string manipulation with observables.

linkconcat()

Concats two or more observables or values. The first value MUST be a string or an observable emitting strings:

1import { concat } from 'rxmetics';

2import { mod } from 'rxmetics/pipes';

3import { interval } from 'rxjs';

4

5concat('', interval(1000), ' : ', interval(10).pipe(mod(100)))

6.subscribe(v => document.body.textContent = v);

You can also use the concat() pipe instead. As before, you MUST pipe it to an observable emitting strings:

1import { mod, concat } from 'rxmetics/pipes';

2import { interval, of } from 'rxjs';

3

4of('').pipe(

5  concat(interval(1000), ' : '),

6  concat(interval(10).pipe(mod(100)))

7).subscribe(v => document.body.textContent = v);

linkString Templates

You can use rxl template prefix to use observables in your template strings:

1import { rxl } from 'rxmetics';

2import { mod } from 'rxmetics/pipes';

3import { interval } from 'rxjs';

4

5rxl`[PRECISE TIMER]:: ${interval(1000)} : ${interval(10).pipe(mod(100))}`

6  .subscribe(v => document.body.textContent = v);
