Redux Requests Factory

Examples

Installation

redux-requests-factory is available on npm.

npm install redux-requests-factory

store.js

import { createStore, applyMiddleware, combineReducers } from 'redux';
import {
  stateRequestsKey,
  requestsReducer,
  createRequestsFactoryMiddleware,
} from 'redux-requests-factory';

export const reducer = combineReducers({
  [stateRequestsKey]: requestsReducer,
  // ... others reducers
});

const {
  middleware: requestsFactoryMiddleware,
} = createRequestsFactoryMiddleware();

const reduxMiddleware = applyMiddleware(requestsFactoryMiddleware);

const store = createStore(reducer, reduxMiddleware);

export default store;

Usage

import { requestsFactory } from 'redux-requests-factory';

const loadUsersRequest = () =>
  fetch('https://mysite.com/users').then(res => res.json());

export const {
  // actions
  loadDataAction, // do request once (can be dispatched many times, but do request once)

Requests Factory Config

import { requestsFactory } from 'redux-requests-factory';

const {...} = requestsFactory({
  request: ({ id }) => fetch(`https://mysite.com/api/user/${id}`).then(res => res.json()),
  stateRequestKey: 'user',
  serializeRequestParameters: ({ id }) => `${id}`,
  // Debounce
  useDebounce: true,
  debounceWait: 500,
  stringifyParamsForDebounce: ({ id }) => `${id}`,
  debounceOptions: {
    leading: true,
    trailing: false,
    maxWait: 500,
  },
  // Request rejected

    return { type: 'SHOW_NOTIFICATION' }
  }],
  // Request fulfilled
  transformResponse: (response) => response || {},

    // return the actions that should be dispatched when request is fulfilled
    return { type: 'SHOW_NOTIFICATION' }
  }],
  // Loading
  includeInGlobalLoading: true,
});

Required

`config.request`

request is required field, it is should be function that takes parameters (or not) and returns Promise

with params:

const {
  doRequestAction,
  forcedLoadDataAction,
  loadDataAction,
} = requestsFactory({
  request: ({ id }) =>
    fetch(`https://mysite.com/api/user/${id}`).then(res => res.json()),
  stateRequestKey: 'user',
});

doRequestAction({ id: 1 });
// or
forcedLoadDataAction({ id: 1 });
// or
loadDataAction({ id: 1 });

or without params:

const {
  doRequestAction,
  forcedLoadDataAction,
  loadDataAction,
} = requestsFactory({
  request: () => fetch('https://mysite.com/api/users').then(res => res.json()),
  stateRequestKey: 'users',
});

doRequestAction();
// or
forcedLoadDataAction();
// or
loadDataAction();

`config.stateRequestKey`

stateRequestKey is required field, it is should be unique string key between all requests

const {...} = requestsFactory({
  stateRequestKey: 'users',
});

const {...} = requestsFactory({
  stateRequestKey: 'user-posts',
});

// Now the state is like here
// state = {
//   [stateRequestsKey]: {
//     responses: {
//       users: {
//         status: RequestsStatuses.None,
//         response: undefined,
//         error: undefined,
//       },
//       'user-posts': {
//         status: RequestsStatuses.None,
//         response: undefined,
//         error: undefined,
//       },
//     },
//   },
// };

Serialize

`config.serializeRequestParameters`

serializeRequestParameters is not required field, it is should be function that takes parameters and returns string.

When used serializeRequestParameters all selectors return function that takes parameters and returns selected value. When used serializeRequestParameters params are required for all actions.

const {
  loadDataAction,
  forcedLoadDataAction,
  doRequestAction,
  cancelRequestAction,
  requestFulfilledAction,
  requestRejectedAction,
  setErrorAction,
  setResponseAction,
  resetRequestAction,

  responseSelector,
  errorSelector,
  requestStatusSelector,
  isLoadingSelector,
  isLoadedSelector,
} = requestsFactory({
  request: ({ id }) =>
    fetch(`https://mysite.com/api/user/${id}`).then(res => res.json()),
  stateRequestKey: 'user',
  serializeRequestParameters: ({ id }) => `${id}`,
});

loadDataAction({ id: 1 });
forcedLoadDataAction({ id: 1 });
doRequestAction({ id: 1 });
cancelRequestAction({ id: 1 });
setErrorAction({
  error: new Error(),
  params: { id: 1 },
});
setResponseAction({
  response: { id: 1, name: 'Name' },
  params: { id: 1 },
});
resetRequestAction({ id: 1 });

responseSelector(store)({ id: 1 });
errorSelector(store)({ id: 1 });
requestStatusSelector(store)({ id: 1 });
isLoadingSelector(store)({ id: 1 });
isLoadedSelector(store)({ id: 1 });

// loadDataAction({ id: 1 });
// loadDataAction({ id: 2 });
// loadDataAction({ id: 3 });
//
// Now the state is like here
// state = {
//   [stateRequestsKey]: {
//     responses: {
//       user: {
//         '1': {
//           status: RequestsStatuses.Loading,
//           response: undefined,
//           error: undefined,
//         },
//         '2': {
//           status: RequestsStatuses.Loading,
//           response: undefined,
//           error: undefined,
//         },
//         '3': {
//           status: RequestsStatuses.Loading,
//           response: undefined,
//           error: undefined,
//         },
//       },
//     },
//   },
// };

Debounce

`config.useDebounce`

useDebounce is not required field, default value - false.

When useDebounce: true requestsFactory creates debounced actions doRequestAction, forcedLoadDataAction and loadDataAction that delays dispatch action with same params until after wait config.debounceWait milliseconds have elapsed since the last time the debounced action was dispatched. Detect same params helps config.stringifyParamsForDebounce. For debounce used lodash.debounce and you can use own debounce options config.debounceOptions.

const {...} = requestsFactory({
  useDebounce: true,
});

`config.debounceWait`

debounceWait is not required field, default value - 500. Used when config.useDebounce: true.

const {...} = requestsFactory({
  debounceWait: 300,
});

`config.debounceOptions`

debounceOptions is not required field, default value:

{
  leading: true,
  trailing: false,
  maxWait: config.debounceWait,
}

It is options for lodash.debounce. Used when config.useDebounce: true.

const {...} = requestsFactory({
  debounceOptions: {
    leading: true,
    trailing: false,
    maxWait: 300,
  },
});

`config.stringifyParamsForDebounce`

stringifyParamsForDebounce is not required field, default value - JSON.stringify. It is should be function that takes parameters and returns string. Used when config.useDebounce: true.

const {...} = requestsFactory({
  request: ({ id }) => fetch(`https://mysite.com/api/user/${id}`).then(res => res.json()),
  stateRequestKey: 'user',
  stringifyParamsForDebounce: ({ id }) => `${id}`,
});

Transform

`config.transformError`

transformError is not required field, it is should be function that takes request error or undefined and returns transformed error or undefined. transformError used for errorSelector.

const { errorSelector } = requestsFactory({
  transformError: error => error && `Error: ${error.message}`,
});

errorSelector(state); // undefined  or `Error: ${error.message}`

`config.transformResponse`

transformResponse is not required field, it is should be function that takes request response or undefined and returns transformed response. transformResponse used for responseSelector. Better use transformResponse for setting default value.

NOTE: For best performance, do not use transformResponse with serializeRequestParameters for expensive transformations. For all expensive transforms better use reselect.

const {
  responseSelector,
} = requestsFactory({
  transformResponse: (response) => response || [],,
});

responseSelector(state); // []

Actions

`config.rejectedActions`

rejectedActions is not required field, default value - []. It is should be array with actions or with functions that takes object { error, request, state } as parameter and returns action or [action, action, ...] that will be dispatched when request is rejected.

const {...} = requestsFactory({
  request: ({ id }) => fetch(`https://mysite.com/api/user/${id}`).then(res => res.json()),
  stateRequestKey: 'user',
  rejectedActions: [
    { type: 'SHOW_NOTIFICATION' }, // simple action
    ({ error, request: { id }, state }) => {
      // ...
      return id === 1 ? { type: 'SHOW_ERROR' } : null;
    }, // function that returns an action or null
    ({ error, request: { id }, state }) => {
      // ...
      return [{ type: 'SHOW_ERROR' }, (id === 1 ? { type: 'SHOW_ERROR' } : null) ];
    }, // function that returns an array with actions or null
  ],
});

`config.fulfilledActions`

fulfilledActions is not required field, default value - []. It is should be array with actions or with functions that takes object { response, request, state } as parameter and returns action or [action, action, ...] that will be dispatched when request is fulfilled.

const {...} = requestsFactory({
  request: ({ id }) => fetch(`https://mysite.com/api/user/${id}`).then(res => res.json()),
  stateRequestKey: 'user',
  fulfilledActions: [
    { type: 'SHOW_NOTIFICATION' }, // simple action
    ({ response, request: { id }, state }) => {
      // ...
      return !response ? { type: 'SHOW_ERROR' } : null;
    }, // function that returns an action or null
    ({ response, request: { id }, state }) => {
      // ...
      return [{ type: 'SHOW_NOTIFICATION' }, (!response ? { type: 'SHOW_ERROR' } : null) ];
    }, // function that returns an array with actions or null
  ],
});

Global Loading

`config.includeInGlobalLoading`

includeInGlobalLoading is not required field, default value - true. It is should be boolean. When includeInGlobalLoading: true and request is loading, global isSomethingLoadingSelector will be return true. If includeInGlobalLoading: false you can use isLoadingSelector

import { isSomethingLoadingSelector } from 'redux-requests-factory';

const { isLoadingSelector } = requestsFactory({
  includeInGlobalLoading: false,
});

Use the silent option for the following actions to temporarily disable the includeInGlobalLoading property:

loadDataAction(params, { silent: true });
forcedLoadDataAction(params, { silent: true });
doRequestAction(params, { silent: true });
cancelRequestAction(params, { silent: true });

`config.globalLoadingTimeout`

globalLoadingTimeout is value in ms. After the specified time has passed, the request is excluded from global loading but is not cancelled.

Others

`config.dispatchFulfilledActionForLoadedRequest`

dispatchFulfilledActionForLoadedRequest is not required field, default value - false. It is should be boolean. When dispatchFulfilledActionForLoadedRequest: true and the request is loaded and new loadDataAction is dispatched, then the requestFulfilledAction and config.fulfilledActions will be dispatched again.

const { loadDataAction, requestFulfilledAction } = requestsFactory({
  dispatchFulfilledActionForLoadedRequest: true,
});

Create Redux Requests Factory

Used if you need more than one instance of createReduxRequestsFactory

import createReduxRequestsFactory from 'redux-requests-factory';

export const {
  stateRequestsKey, // 'api-key-one'
  createRequestsFactoryMiddleware, // Middleware for 'api-key-one'
  requestsFactory, // requestsFactory for 'api-key-one'
  requestsReducer, // requestsReducer for 'api-key-one'
  isSomethingLoadingSelector, // isSomethingLoadingSelector for 'api-key-one'
} = createReduxRequestsFactory({
  stateRequestsKey: 'api-key-one',
});

export const {
  stateRequestsKey, // 'api-key-two'
  createRequestsFactoryMiddleware, // Middleware for 'api-key-two'
  requestsFactory, // requestsFactory for 'api-key-two'
  requestsReducer, // requestsReducer for 'api-key-two'
  isSomethingLoadingSelector, // isSomethingLoadingSelector for 'api-key-two'
} = createReduxRequestsFactory({
  stateRequestsKey: 'api-key-two',
});

SSR

store.js

const makeStore = initialState => {
  const { middleware, toPromise } = createRequestsFactoryMiddleware();
  const reduxMiddleware = applyMiddleware(middleware);

  const store = createStore(reducer, initialState, reduxMiddleware);

  store.asyncRequests = toPromise;

  return store;
};

app.js

const loadData = async ({ isServer, store }) => {
  store.dispatch(loadUsersAction());

  if (isServer) {
    await store.asyncRequests();
  }
};
