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
-
Set the
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 tohttps://<appname>.herokuapp.com
.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 andROOT_URL
is undefined, it will default tohttps://<appname>.herokuapp.com
).MONGO_URL
: The URL to mongodb. It not defined, it will default the value ofMONGODB_URI
,MONGOLAB_URI
, orMONGOHQ_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 andapp/
subdirectory; if you put your app anywhere else (likesrc/
), 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, defineBUILDPACK_PRELAUNCH_METEOR=1
. Reference issue.BUILDPACK_VERBOSE
: SetBUILDPACK_VERBOSE=1
to enable verbose bash debugging during slug compilation. Only takes effect after the environment variables have been loaded.
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
build.
Extras included in this branch:
mongo_url.sh
: IfMONGO_URL
is empty, set it to the value ofMONGODB_URI
,MONGOLAB_URI
, orMONGOHQ_URL
(in order).root_url.sh
: IfROOT_URL
is empty andHEROKU_APP_NAME
is available, setROOT_URL
tohttps://$HEROKU_APP_NAME.herokuapp.com
phantomjs.sh
: Include phantomjs for use withspiderable
.
This buildpack creates a directory .meteor/heroku_build
($COMPILE_DIR
)
inside the app checkout, and puts all the binaries and the built app in there.
So it ends up having the usual unixy bin/
, lib/
, share
etc
subdirectories. Those directories are added to $PATH
and
$LD_LIBRARY_PATH
appropriately.
So $COMPILE_DIR/bin
etc are great places to put any extra binaries or stuff
if you need to in custom extras.
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.
