node.js - NodeJS File Creation as an Object? -


i dont want save file locally, want create file object uploaded through api. 

    var request = require("request");     var fs = require("fs");      var arr = [      [4, 56, 7, 3, 345],      [34, 5, 2, 5, 7]        ];      var r = requests.post("https://slack.com/api/files.upload", function(err, res,body){        console.log(body)''      }       var form = r.form();      form.append('token', token)      form.append("filename", filename)      form.append('file', new buffer(arr));

i want know if possible not save file locally , add in file data form submitted through api?

yes, can pipe file directly request without saving value. however, depends on data coming , how can access it. when fs.createreadstream('<filepath>') you're creating readstream pass request part of form data. request uses stream read file , pass through resource requested.

the below code, take file accessible server , pass through request desired endpoint. 

var request = require('request'); var fs = require('fs');  var formdata = {   token: token,   filename: filename,   file: fs.createreadstream('<filepath>'); };  request({   method: 'post',   url: 'https://slack.com/api/files.upload',   form: formdata }, function(err, res, body) {    console.log(json.stringify(body, null, 2)); });
