react-native-http-module

react-native-http-module is a light weight library that provides the functionality to make sample HTTP requests.

WHY react-native-http-module ?

React-native basically uses XHR to make API requests. But the android Wear OS does not support XHR requests. Hence the need to build this custom library has come.

This react-native-http-module library supports HTTP requests in wear OS.

Being promise based is another advantage of this library

GETTING STARTED

$ npm install react-native-http-module --save

MOSTLY AUTOMATIC INSTALLATION

$ react-native link react-native-http-module (in react-native versions <= 60)

CURRENT SUPPORT & USAGE

This react-native-http-module library currently supports/exports the basic methods(get, post & request) to make a API request. The request method supports all the available methods like get, post, delete, put...

import HttpModule from 'react-native-http-module';

const httpModule = new HttpModule(baseURL, headers);

This module supports a default constructor that takes the following args:

• baseURL - The application's default endpoint URL. If this is empty, complete endpoint URL given is considered.
• headers - The default headers that can be set for set of upcoming requests.

GET

httpModule.get(URL, HEADERS).then(...).catch(...);

POST

httpModule.post(URL, HEADERS, BODY).then(...).catch(...);

REQUEST

httpModule.request(URL, METHOD: 'get'|'post'|'delete'|'put', HEADERS, BODY).then(...).catch(...);
