redux-cycles-http v0.5.0

redux-cycles-http

Default HTTP flow cycle to use with redux-cycles.

Installation

yarn add redux-cycles-http

or

npm install --save redux-cycles-http

Usage

Setup

Setup redux-cycles as usual along with Cycle.js HTTP driver and add httpCycle to your cycles:

import { createCycleMiddleware } from 'redux-cycles'
import { run } from '@cycle/run'
import { makeHTTPDriver } from '@cycle/http'
import { combineCycles } from 'redux-cycles'
import httpCycle from 'redux-cycles-http'

const cycleMiddleware = createCycleMiddleware()
const { makeActionDriver } = cycleMiddleware
const middlewares = [cycleMiddleware]

export const cycles = combineCycles(
  httpCycle
)

run(cycles, {
  ACTION: makeActionDriver(),
  HTTP: makeHTTPDriver(),
})

Dispatch actions

export function somedataFetch(id) {
  return {
    type: ACTION_TYPE,
    request: {
      url: `${API_ENDPOINT}/path/${encodeURIComponent(id)}`,
      method: 'GET',
    }
  }
}

Match it in reducer

export default function reducer(state = INITIAL_STATE, action) {
  switch (action.type) {
    case success(ACTION_TYPE):
      return {
        ...state,
        response: action.payload,
      }
    default:
      return state
  }
}

Success action payload contains:

• data - response data,
• request - request matching this response,
• initial - initial action payload.

Waiting for requests to finish

E.g. if you need it for server side rendering.

NB! This requires redux-thunk or similar middleware.

import { awaitable } from 'redux-cycles-http'

static async getInitialProps({ query, store, isServer }) {
  const { id } = query
  await store.dispatch(awaitable(somedataFetch(id)))
  return { isServer }
}

or

import { awaitable } from 'redux-cycles-http'

function getInitialActions() {
  const awaitableFetch = awaitable(somedataFetch())
  return store.dispatch(awaitableFetch).then(response => {
    console.log('My data:', response.body)
    return response
  })
}
