A heroku buildpack for Meteor v1+, designed to be as simple and readable as possible.
To use this with your meteor app and heroku:
Set up your app to deploy to heroku with git.
Set this repository as the buildpack URL:
heroku buildpacks:set https://github.com/AdmitHub/meteor-buildpack-horse.git
Add the MongoLab addon:
heroku addons:create mongolab
ROOT_URL environment variable. This is required for bundling and running the app. Either define it explicitly, or enable the Dyno Metadata labs addon to default to
heroku config:set ROOT_URL="https://<appname>.herokuapp.com" # or other URL
Once that's done, you can deploy your app using this build pack any time by pushing to heroku:
git push heroku master
The following are some important environment variables for bundling and running your meteor app on heroku. Depending on your settings, you may need to override these on heroku. See heroku's documentation for how to set these.
ROOT_URL: The root URL for your app, needed for bundling as well as running. If you enable the Dyno Metadata labs addon and
ROOT_URLis undefined, it will default to
MONGO_URL: The URL to mongodb. It not defined, it will default the value of
MONGOHQ_URL(in order). If you don't use mongolab as a regular addon (and none of the fallbacks are defined), you'll need to set this.
METEOR_APP_DIR: The relative path to the root of your meteor app within your git repository (i.e. the path to the directory that contains
.meteor/). The buildpack will look in the root of your repository and
app/subdirectory; if you put your app anywhere else (like
src/), define this variable to tell the buildpack where to look.
BUILDPACK_PRELAUNCH_METEOR: If your app uses packages that need to compile their assets on first run, you may need meteor to launch prior to bundling. If this applies for you, define
BUILDPACK_PRELAUNCH_METEOR=1. Reference issue.
BUILDPACK_VERBOSE=1to enable verbose bash debugging during slug compilation. Only takes effect after the environment variables have been loaded.
BUILDPACK_CLEAR_CACHE: This buildpack stores the meteor installation in the CACHE_DIR to speed up subsequent builds. Set
BUILDPACK_CLEAR_CACHE=1to clear this cache on startup and after build is done.
BUILD_OPTIONS: Set to any additional options you'd like to add to the invocation of
meteor build, for example
NODEJS_PARAMS: additional parameters for running
nodebinary. This can be used eg. for adjusting garbage collector settings by putting
--optimize_for_size --max_old_space_size=460 --gc_interval=100here
The basic buildpack should function correctly for any normal-ish meteor app,
with or without npm-container. For extra steps needed for your particular build,
just add shell scripts to the
extra folder and they will get sourced into the
Extras included in this branch:
MONGO_URLis empty, set it to the value of
ROOT_URLis empty and
HEROKU_APP_NAMEis available, set
This buildpack creates a directory
inside the app checkout, and puts all the binaries and the built app in there.
So it ends up having the usual unixy
subdirectories. Those directories are added to
$COMPILE_DIR/bin etc are great places to put any extra binaries or stuff
if you need to in custom extras.
Please help us add tips and tricks to the wiki for further help, like usage with Dokku or other environments.
There are a gazillian forks and branches of various buildpacks remixing the words "heroku", "buildpack", and "meteor", many of which are abandoned or outdated or broken, and it's really hard to keep them straight.
So this one is the horse one.
