Tool for packaging Meteor apps for Sandstorm.io

Introduction

Sandstorm is a platform for personal clouds that makes installing apps to your personal server as easy as installing apps to your phone.

Meteor is a revolutionary web app framework. Sandstorm's own UI is built using Meteor, and Meteor is also a great way to build Sandstorm apps.

This package provides a tool, meteor-spk, which wraps Sandstorm's normal spk tool as well as Meteor's tools in order to easily package Meteor apps to run on Sandstorm.

Installing the tool

Prerequisites

Currently, this tool only works on Linux. We may port to Mac OSX in the future.

You must install Sandstorm locally in order to get the spk tool. The easiest way to do that is:

curl https://install.sandstorm.io | bash

Installing meteor-spk from binaries

1. Download and unpack the binary distribution, e.g.:

   mkdir -p ~/projects/meteor-spk
   cd ~/projects/meteor-spk
   curl https://dl.sandstorm.io/meteor-spk-0.6.0.tar.xz | tar Jxf -
   cd meteor-spk-0.6.0

2. Add the directory to your $PATH, or symlink the meteor-spk script into a directory in your $PATH, e.g.:

   ln -s $PWD/meteor-spk ~/bin

Packaging your app

To package your existing Meteor app, do the following:

1. Run meteor-spk init in your app's source tree.
2. Open the generated file sandstorm-pkgdef.capnp in a text editor. Read the comments and fill in as appropriate. In particular you will probably want to change the "new instance" action title.
3. (optional) Run meteor-spk dev to run your app in dev mode. For this to work, you must be running a local Sandstorm server and your user account must be a member of the server's group. The tool will connect to that server and temporarily make your app available for testing. When done testing, use ctrl+C in the terminal to stop.
4. Run meteor-spk pack example.spk to create a Sandstorm package file called example.spk. WARNING: You may want to place this file outside of your source directory as otherwise Meteor will think it is part of the app and will include it in the app bundle. This means if you repeatedly run this command your package will keep including itself and become enormous.
5. You can upload your spk to a Sandstorm server using the "Upload App" button in the Sandstorm UI.

Tips

• As of version 0.1.5, meteor-spk uses Mongo 3.0. Mongo 2.x does not work well for Sandstorm apps as it pre-allocates far too much disk space expecting a large database; Mongo 3.x mostly avoids preallocation. The differences should be invisible to your app. Note that apps built with previous versions of meteor-spk can upgrade safely -- old grains will automatically be migrated to Mongo 3 format on their first run.
• If your app uses accounts, add the package kenton:accounts-sandstorm to integrate with Sandstorm's login system. (See also jacksingleton:accounts-sandstorm-dev to fake Sandstorm user info during development, so that you can use Meteor's auto-refreshing dev mode outside of Sandstorm.)
• That said, there is often no need for accounts because instances of your app are already private, viewable only to the owner and people with whom they explicitly shared it. You might as well give all of these users full access, and rely on Sandstorm for protection.
• If your app is document-oriented, you should design it to host only a single document. Users can create multiple instances of your app if they want multiple documents. In fact, it's better that way, because then the instances can be independently shared.
• All of this means that it's often OK to leave autopublish and insecure on! If all users have full access anyway, and the data set is limited to one document, then there's no problem.

Developing meteor-spk

Installing meteor-spk from source

1. Check out this github repository. Note that you must use the --recursive flag to ensure that submodules are cloned as well:

   git clone --recursive https://github.com/sandstorm-io/meteor-spk.git

2. Run make.

3. Add the directory to your $PATH, or symlink the meteor-spk script into a directory in your $PATH, e.g.:

   ln -s $PWD/meteor-spk ~/bin
