react-native-fetch-blob dev environment

This repository is for developers who interested in modifying and improving react-native-fetch-blob.

prerequisites

  • node.js > 5.1.0
  • A valid Dropbox API token
  • [rnpm](npm unlink) react native package manager

clone the repository

This repository use git submodule, for first time clone

$ git clone --recursive -j8 https://github.com/joltup/react-native-fetch-blob-dev.git

update submodules

$ git submodule update --init --recursive

run and install test app

Before install the test app, you should replace constants DROPBOX_TOKEN and TEST_SERVER_URL in src/test/tests.js

// replace this with your machine's IP, it can be "localhost:8123" when using simulator
+ const TEST_SERVER_URL = 'http://192.168.0.14:8123'                                                                                     
// replace this with your dropbox token
+ const DROPBOX_TOKEN = 'fsXcpmKPrHgAAAAAAAAAoXZhcXYWdgLpQMan6Tb_bzJ237DXhgQSev12hA-gUXt4'

To generate test app template, simply execute npm test <platform> command from root folder.

$ npm test ios
# or
$ npm test android
  • Note: This repo currently uses Node >=6.9.0. Make sure you have a compatible version.

The script will initialize a new RN app named RNFetchBlobTest (right in the project's /RNFetchBlobTest folder), it will also launch the test app by the platform given, and a nodejs server for test. You only need to run this script once.

dev server

There is a test server for sending and receiving requests from test app, also it watches files in several directories and copy changed files to test app's folder.

To install dev server modules, execute the following command from root folder

$ npm install

To start dev server, go test-server folder and execute

$ node server

work on android native code

After the test app installed, change settings.gradle in RNFetchBlobTest/android/

rootProject.name = 'RNFetchBlobTest'

include ':app'
include ':react-native-fetch-blob'
// change this line so that the fetch-blob module in test app points to android project in src folder
- project(':react-native-fetch-blob').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-fetch-blob/android')                         
+ project(':react-native-fetch-blob').projectDir = new File(rootProject.projectDir, '../../src/android')

Now open the android project in RNFetchBlobTest/android folder with you IDE, every changes you made to react-native-fetch-blob project will directly maps to src folder.

Always keep in mind, once you changed native code you have to recompile it otherwise it uses the same native executables.

work on ios native code

After the test app installed, open the .xcodeproj file inside RNFetchBlobTest/ios with XCode.

Delete existed RNFetchBlob.xcodeproj in RNFetchBlobTest -> Libraries since this one is the one in RNFetchBlobTest/node_modules/react-native-fetch-blob/ios/ we're going to change its reference to src/ios/RNFetchBlob.xcodeproj.

Right click on Libraries select add new files to "RNFetchBlobTest.xcodeproj" .. and select src/ios/RNFetchBlob.xcodeproj. Now every changes you made to RNFetchBlob project will directly maps to the one in src folder.

Also, you have to add CameraRoll to the RNFetchBlobTest project otherwise the test case will crash the app.

Always keep in mind, once you changed native code you have to recompile it otherwise it uses the same native executables.
