javascript - meteor.js and npm require fs -

i confused, need use fs package meteor.js fw.

from meteor version 0.6> need use npm.require this:

var fs = npm.require('fs'); 

but when error appear: npm not defined

how solve it? tried mrt add npm hm...

btw: have /root/packages/npm

edit code in both client/server side folder moved block server

var fs; if(meteor.isserver) {   fs = meteor.require('fs'); }  fs.writefile(path + name,...  getting error: cannot call method writefile of undefined 

solved solved error wraping whole content meteor.isserver {... if someoen explain me curiosity why not work above?

you need add package.js in app or smart package explicitly specifies dependency via npm.depends before can use npm.require. don't need npm.depends or smart package if using built-in npm package such fs, still need make sure using on server-side , not client side.

for example, check out package.js file meteor package pulls in sharejs: https://github.com/mizzao/meteor-sharejs/blob/master/sharejs-ace/package.js
