RxJS JMESPath package

Adaptation of the official Javascript JMESPath package to work along with RxJS.

Passes all the original compliance tests.

Installation

``bash
yarn add @platyplus/rx-jmespath
`

Usage

$3

`typescript
function search$(
expression: string | Observable,
options: SearchOptions
): (data$: Observable) => Observable
`

Example:

`js
import { search$ } from '@platyplus/rx-jmespath'
import { of } from 'rxjs'

of({ a: { b: { c: 'hello' } } })
.pipe(search$('a.b.c'))
.subscribe((result) => {
console.log(result) // <- returns 'hello'
})
`

$3

Exact same function as in the official package:

`typescript
search(obj: any, expression: string ) => any
`

Options

`typescript
type SearchOptions = T & {
getField?: FieldGetter
getIdentity?: IdentityGetter
circularData?: boolean
}
`

$3

`typescript
const getField: FieldGetter> = (
obj: any,
property: string | number,
options: SearchOptions
): Observable => {
return of(obj[key] ?? null)
}
`

$3

`typescript
const getIdentity: IdentityGetter> = (
obj: any,
options: SearchOptions
): Observable => {
return of(obj)
}
`

$3

Sometimes, objects are mutually referenced, so browsing them entirely would create an infinite loop. You can prevent this in setting this option to true.

When true, the expression * expression raises an error instead of making the processing fail.

The circularData option defaults to false.
