You may add metadata to a file on the client side by setting the file. It is sometimes useful to add metadata to a file prior to uploading the file. event.error The I/O error that was encountered. Event PropertiesĪn error was encountered in the saving of the file. There are 147 other projects in the npm registry using socket.io-stream. Start using socket.io-stream in your project by running npm i socket.io-stream. It is recommended that you check to tell whether or not the file was saved without errors. Latest version: 0.9.1, last published: 7 years ago. event.interrupt true if the client said that the data was interrupted (not completely sent) false otherwiseĪ file has been saved.event.buffer A buffer containing the data received from the client npm install socket.io-client You can then proceed to import and create a connection like so: import React from 'react' import io from 'socket.io-client' let ENDPOINT ' let socket io(ENDPOINT) Socket connection and disconnection We have succeeded in setting up both our server side and client side.event.file The same file object that would have been passed during the start event earlier.Note: In the "progress", "complete", "saved", and "error" events, if you are letting the module save the file for you, the file object will contain two additional properties: base, the new base name given to the file, and pathName, the full path at which the uploaded file was saved.ĭata has been received from the client. Note: encoding is either "text" if the file is being transmitted as plain text or "octet" if it is being transmitted using an ArrayBuffer. Both components have a nearly identical API. event.file An object containing the file's name, mtime, encoding, meta, success, bytesLoaded, and id. Socket.io is a Javascript library for web apps that allows real-time communication between clients and servers.It has two parts: a client-side library that runs in the browser, and a server-side library for node.js.The client has started the upload process, and the server is now processing the request. instance.removeListener("type", callback).Instances of SocketIOFileUpload implement Node's EventEmitter interface. addEventListener ( "error", function ( data ) Events In this recipe, we will use Socket.IO to upload a file to our local filesystem and then send a message to the client to display the image when it is done uploading. The client-side interface is inside the SocketIOFileUpload namespace. Socket.IO allows us to upload files in real time and display the uploaded images as needed. instance.uploadValidator(event, callback).instance.dir = "/path/to/upload/directory".Tip Notice that the query token will be handled by a dependency. instance.listenOnArraySubmit(submitButton, input) Open your browser at There you can set: The 'Item ID', used in the path.Since version 0.4, this module also supports monitoring file upload progress. The intended audience are single-page web apps, but other types of Node.JS projects may benefit from this library. instance.listenOnSubmit(submitButton, input) Throughout the process, if their browser supports WebSockets, the user will not submit a single HTTP request.A longer example is available at the bottom of the readme. For the detailed API, continue reading below. connect ( ) var uploader = new SocketIOFileUpload ( socket ) uploader.
