node.js - How do I stream large files over ssh in Node? -

i'm trying stream cat command using ssh2 module hangs @ point of execution. i'm executing cat there.txt there.txt around 10 mb or so.

for example:

local = fs.createwritestream('here.txt'); conn.exec('cat there.txt', function(err, stream) {      if (err) throw err;      stream.pipe(local).on('finish, function() { console.log('done'); }); } 

this stops @ 1 point. i've piped stream local stdout, , hangs after while. in actual code, pipe through bunch of other transform streams think better transferring files local system first (the files may larger 200mb).

try out createreadstream serving huge files:

fs.exists(correctfilepath, function(exists) {   if (exists) {     var readstream = fs.createreadstream(correctfilepath);      console.log("about serve " + correctfilepath);      res.writehead(200);     readstream.setencoding("binary");      readstream.on("data", function (chunk) {         res.write(chunk, "binary");     });      readstream.on("end", function () {         console.log("served file " + correctfilepath);         res.end();     });      readstream.on('error', function(err) {         res.write(err + "\n");         res.end();         return;     });   } else {     res.writehead(404);     res.write("no data\n");     res.end();   } });
