meteorjs image upload / conversion

问题

I need to upload a file to meteor, do some image manipulation on it (image conversion if necessary, generate thumbnail from image ) and then store it in an external image storage server (s3). This should be as fast as possible. Do you have any recommendations for a nodejs image processing library ? also how i can upload a file to meteorjs ?

Thanks

回答1:

I ended up with the following solution:

1) meteor server side route for a custom upload url

__meteor_bootstrap__.app.stack.splice (0, 0, {
    route: '/upload',
    handle: function (req,res, next) {
        //handle upload
    }.future ()
});

2) use formidable nodejs module inside the function for file upload

Easiest solution I have found is using FilePicker.io. It's extremely easy to integrate into your Meteor App and plugs directly into S3.

In my startup (hausor.com) I use https://github.com/CollectionFS/Meteor-CollectionFS and with additional plugins it supports amazon S3 file upload and image scaling/cropping.

I don't think Meteor has any support for uploads; perhaps something is planned in the future. In the meantime, I'd either (assuming you can reading the file with a FileReader or something):

a) insert the file into the mongo and then delete it when it is saved to S3

b) save it up to S3 from the client (not sure if there's a "safe" way to do this.. ie without giving away your credentials, but it could be worth exploring).

c) [if you can't use a FileReader] use an iframe or something to POST to an external server you can control that does handle uploads and then communicate with it from the meteor server.

Kindly check one of my answer here : File upload and download using meteor

I am using busboy for file upload and just use fs = Npm.require("fs") for file writing: Just put these inside busboy:, the save to is the path where you uploaded, simple us APACHE or file hosting and use other port on it..

file.pipe(fs.createWriteStream(saveTo))
