Client socket.io files

Can be used in team with instance. By default Siofu client sends data the server on a different topic depending of the progress of the upload:. If wrapData is set to true, Siofu will use only one topic specified by instance. The following examples are example settings for the client. You can personalise the 'action' and 'message' key by passing a object to wrapData instance.

The settings on the server should be the inverse of the settings on the client. For example, if the client has wrapData. It's also possible to add additional data for strongly typed topic or secure pipeline or acknowledgement :.

If true this will expose some functions used in intern to personalize action on the topic. This is used alongside with wrapData to add custom check or logic before process the file upload. If true you will have access to:.

This means that you can do:. The user has chosen files to upload, through any of the channels you have implemented. If you want to cancel the upload, make your callback return false. This event is fired immediately following the choose event, but once per file. If you want to cancel the upload for this individual file, make your callback return false. Part of the file has been loaded from the file system and ready to be transmitted via Socket. This event can be used to make an upload progress bar.

You can compute the percent progress via event. We are awaiting a response from the server about whether the upload was successful; when we receive this response, a complete event will be dispatched. If you are using Connect-based middleware like Express, pass this value into the middleware.

If specified, the module will attempt to save uploaded files in this directory. The module will intelligently suffix numbers to the uploaded filenames until name conflicts are resolved. It will also sanitize the filename to help prevent attacks. The last-modified time of the file might be retained from the upload. If this is of high importance to you, I recommend performing some tests, and if it does not meet your needs, submit an issue or a pull request.

Use these UNIX permissions when saving the uploaded file. Defaults to The maximum file size, in bytes, to write to the disk. If file data is received from the client that exceeds this bound, the data will not be written to the disk and an "error" event will be thrown.

Defaults to null , in which no maximum file size is enforced. Note that the other events like "progress", "complete", and "saved" will still be emitted even if the file's maximum allowed size had been exceeded.

However, in those events, event. Whether or not to emit an error event if a progress chunk fails to finish writing. In most cases, the failure is a harmless notification that the file is larger than the internal buffer size, but it could also mean that the file upload triggered an ENOSPC error.

It may be useful to enable this error event if you are concerned about uploads running out of space. The client has started the upload process, and the server is now processing the request. A file has been saved. It is recommended that you check event. Here you can find CDN for various versions. Sign up or log in Sign up using Google. Sign up using Facebook.
