How can I deploy node modules in a Meteor app on meteor.com?

Question

I have an application that uses the node twit module that is available via

npm install twit

I deployed the node module locally from .meteor/local/build/server/

So, it is visible at .meteor/local/build/server/node_modules/twit

I tried installing it at project root but the project did not find the module. Which led me to the above solution which works.

My application now runs fine locally. I am able to run and do everything and can interact with Twitter from my Meteor server side or client side depending on what I want to do. No crashes.

When I deploy to meteor.com through the command

meteor deploy [appname] --password

The application deploys successfully.

When I attempt to access the (app at anonistream.meteor.com)[anonistream.meteor.com] from a browser it fails and the logs contain this error.

Does anyone have any suggestions on how this might be accomplished?

Answer 1

As of Meteor 6.0, now we need to use Npm.require() instead. Additionally, we need to declare the module as global variables, since Meteor now has file-level scope.

  var path = Npm.require('path');
  var fs = Npm.require('fs');
  var base = path.resolve('.');
  var isBundle = fs.existsSync(base + '/bundle');
  var modulePath = base + (isBundle ? '/bundle/static' : '/public') + '/node_modules';
  MODULE_NAME = Npm.require(modulePath + '/MODULE_NAME'); // NOTE, this is going to be a global variable

finally, I wrote like this. it works both in local and meteor sever. thx Ian :D

install npm module inside "app/public":

    app/public# npm install MODULE_NAME

inside app/server/server.js:

Meteor.startup(function () {
    var require = __meteor_bootstrap__.require;
    var path = require('path');
    var base = path.resolve('.');
    var isBundle = path.existsSync(base + '/bundle');
    var modulePath = base + (isBundle ? '/bundle/static' : '/public') + '/node_modules';

    var MODULE_NAME = require(modulePath + '/MODULE_NAME');
});
