Request middleware for Redux

Works like redux promise middleware. Resolves request objects from superagent or BackboneORM models. Can work with anything with a similar callback style api.

requestMiddleware, responseParserMiddleware

Usage

1. Add to your middleware

import {createStore, applyMiddleware} from 'redux'
import {requestMiddleware, responseParserMiddleware} from 'redux-request-middleware'
import rootReducer from './reducers'

const store = createStore(
  rootReducer,
  applyMiddleware(requestMiddleware, responseParserMiddleware),
)

2. Add a request property to your actions that contains the request you want to dispatch

// Superagent
import request from superagent

dispatch({
  type: 'GET_SOMETHING',
  request: request.get('/something'),
  callback: err => console.log('This will be called when the request completes. Useful for navigating after a request returns (login, etc). Errors should not be handled here - an error action is sent, work with that.'),
})


// BackboneORM
import Task from './models/task'

dispatch({
  type: 'GET_TASKS',
  request: Task.cursor({active: true}),
})


// Callback
import Task from './models/task'

dispatch({
  type: 'GET_TASKS',
  request: callback => loadSomeThingsManually(callback),
})

requestModifierMiddleware

Appends a user id to any superagent request or BackboneORM cursor function it finds on an action.

It's designed to work alongside redux-request-middleware which will perform the request and dispatch the relevant (sub)-actions.

It must be included before redux-request-middleware when combining middleware, otherwise the requests will be sent before it has a chance to alter the query.

Options

• getValue(store): A function that takes a store and returns a value object to append to the request. You need to supply this.

• getRequest(action): Return a request from an action, defaults to returning action.request

• setValue(request, value): A function that appends value to the request somehow. By default it's this:

export function setValue(request, value) {
  if (_.isObject(request._cursor)) {
    _.merge(request._cursor, value)
  }
  if (_.isFunction(request.query)) {
    request.query(value)
  }
  return request
}

Usage

This example creates middleware that adds a $user_id param with the current user's id to requests

const requestModifierMiddleware = createRequestModifierMiddleware({
  getValue: store => {
    const {auth} = store.getState()
    const value = {}
    if (auth.get('user')) value.$user_id = auth.get('user').get('id')
    return value
  },
})

i.e. if you have a user with id 1234, all modified requests will now look like /api/some_model/?$user_id=1234

requestLoggerMiddleware

Auto logs all requests to the console. Add to your redux middleware to have each request logged (useful for react-native debugging).
