Add blob implementation with WebSocket integration
Summary: This is the first PR from a series of PRs grabbou and me will make to add blob support to React Native. The next PR will include blob support for XMLHttpRequest. I'd like to get this merged with minimal changes to preserve the attribution. My next PR can contain bigger changes. Blobs are used to transfer binary data between server and client. Currently React Native lacks a way to deal with binary data. The only thing that comes close is uploading files through a URI. Current workarounds to transfer binary data includes encoding and decoding them to base64 and and transferring them as string, which is not ideal, since it increases the payload size and the whole payload needs to be sent via the bridge every time changes are made. The PR adds a way to deal with blobs via a new native module. The blob is constructed on the native side and the data never needs to pass through the bridge. Currently the only way to create a blob is to receive a blob from the server via websocket. The PR is largely a direct port of https://github.com/silklabs/silk/tree/master/react-native-blobs by philikon into RN (with changes to integrate with RN), and attributed as such. > **Note:** This is a breaking change for all people running iOS without CocoaPods. You will have to manually add `RCTBlob.xcodeproj` to your `Libraries` and then, add it to Build Phases. Just follow the process of manual linking. We'll also need to document this process in the release notes. Related discussion - https://github.com/facebook/react-native/issues/11103 - `Image` can't show image when `URL.createObjectURL` is used with large images on Android The websocket integration can be tested via a simple server, ```js const fs = require('fs'); const http = require('http'); const WebSocketServer = require('ws').Server; const wss = new WebSocketServer({ server: http.createServer().listen(7232), }); wss.on('connection', (ws) => { ws.on('message', (d) => { console.log(d); }); ws.send(fs.readFileSync('./some-file')); }); ``` Then on the client, ```js var ws = new WebSocket('ws://localhost:7232'); ws.binaryType = 'blob'; ws.onerror = (error) => { console.error(error); }; ws.onmessage = (e) => { console.log(e.data); ws.send(e.data); }; ``` cc brentvatne ide Closes https://github.com/facebook/react-native/pull/11417 Reviewed By: sahrens Differential Revision: D5188484 Pulled By: javache fbshipit-source-id: 6afcbc4d19aa7a27b0dc9d52701ba400e7d7e98f
