A library to make it easy to work with remote data. Compatible with the fp-ts
ecosystem, but it's not required.
RemoteData represents a value that can be in one of four states:
- Loading
- Error
- Empty
- Success
import * as D from '@jvlk/fp-ts-remote-data'
import { pipe } from 'fp-ts/function'
import useBlogRequest from './useBlogRequest'
import Loading from './Loading'
import Error from './Error'
import Empty from './Empty'
import Blog from './Blog'
function Component() {
const blog = useBlogRequest()
return pipe(
blog,
D.fold(
() => <Loading />),
err => <Error error={err}>,
() => <Empty/>,
entries => <Blog entries={entries}>
)
}
Using NPM:
npm i @jvlk/fp-ts-remote-data
Using Yarn:
yarn add @jvlk/fp-ts-remote-data
The start of this repo began as a clone of https://github.com/sylcastaing/fp-ts-remote-data. I have modified it and diverged from it. That library is much more "sound" from a fp-ts
types perspective, but I wanted to create something that was focused more on developer usability. I've removed many of the functions in favor of simplifying things. I have also added the 4th state of empty
to avoid having to use a value of Option
if the results don't contain any data.
The original concept of the RemoteData type comes from How Elm Slays a UI Antipattern.
