Redux-api

Flux REST API for redux infrastructure

Introduction

redux-api solves the problem of writing clients to communicate with backends. It generates actions and reducers for making AJAX calls to API endpoints. You don't need to write a lot of boilerplate code if you use redux and want to exchange data with server.

Inspired by Redux-rest and is intended to be used with Redux.

Documentation

See DOCS.md for API documentation.

Use cases

• AuthorizationJWT.md - example of JWT Authorization
• Scoping.md - use scoping or using multiple redux-api instance without naming intersections.

Install

With npm:

npm install @3plus/redux-api --save

=======

Remote calls

redux-api doesn't bind you to a technology to make AJAX calls. It uses configurable adapters - a pretty simple function which receives 2 arguments: endpoint and options, and returns a Promise as result. The default adapter uses isomorphic-fetch, and has an implementation like this:

function adapterFetch(url, options) {
  return fetch(url, options);
}

However, you are not tied to using isomorphic-fetch. For instance, if you prefer to use jQuery, you can use the following adapter:

function adapterJquery(url, options) {
  return new Promise((success, error)=> {
    $.ajax({ ...options, url, success, error });
  });
}

This implementation allows you to make any request and process any response.

And of course you have to set up adapter to your redux-api instance before using.

  reduxApi(....).use("fetch", adapterFetch)

Example

rest.js

import "isomorphic-fetch";
import reduxApi, {transformers} from "@3plus/redux-api";
import adapterFetch from "@3plus/redux-api/lib/adapters/fetch";
export default reduxApi({
  // simple endpoint description
  entry: `/api/v1/entry/:id`,
  // complex endpoint description
  regions: {
    url: `/api/v1/regions`,
    // reimplement default `transformers.object`
    transformer: transformers.array,
    // base endpoint options `fetch(url, options)`
    options: {
      headers: {
        "Accept": "application/json"
      }
    }
  }
}).use("fetch", adapterFetch(fetch));
