RemoteData type Build Status

Description

RemoteData is an ADT (algebraic data type) described in this article. Heavily based on fp-ts lib.

Installation

npm i --save @devexperts/remote-data-ts

How to lift (wrap) your data in RemoteData:

As you remember RemoteData is an union of few types: RemoteInitial, RemotePending, RemoteFailure and RemoteSuccess.

While your data in initial or pending state just use initial or pending constant, because you don't have any real values in this case.

import { initial, pending } from '@devexperts/remote-data-ts';

const customers = initial;
// or
const customers = pending;

When you receive data from server, use failure or success function, it depends on what you received:

import { failure, success } from '@devexperts/remote-data-ts';
import { apiClient } from 'apiClient';
import { TCustomer } from './MyModel';

const getCustomers = (): RemoteData<TCustomer[]> => {
   const rawData: TCustomer[] = apiClient.get('/customers');

   try {
        const length = rawData.length;

        return success(rawData);
   }
   catch(err) {
        return failure(new Error('parse error'));
   }
}

How to fold (unwrap) your data from RemoteData:

Finally you pass data to the component and want to render values, so now it's time to get our values back from RemoteData wrapper:

import { NoData, Pending, Failure } from './MyPlaceholders';
import { TCustomer } from './MyModel';

type TCustomersList = {
    entities: RemoteData<TCustomer[]>;
};

const CustomersList: SFC<TCustomersList> = ({ entities }) => entities.foldL(
    () => <NoData />,
    () => <Pending />,
    err => <Failure error={err} />,
    data => <ul>{data.map(item => <li>{item.name}</li>)}</ul>
);
