heroku-config
Push and pull your Heroku configs to your local environment.
Heavily inspired by ddollar's version, but using the new Heroku cli.
⚠️
Disclaimer
⚠️
Running this code has the potential to delete your configurations if misused.
Specifically, the -o flag will overwrite values at the destination. Only use that if the source has more up to date info and you're feeling brave. Otherwise, this merges configs and is fairly safe. Just thought you should know.
Also, the -c flag will delete values that didn't exist locally when you pushed. Only use it if you know that.
Usage
You can install the package by running
% heroku plugins:install heroku-config
This package includes two commands:
heroku config:pull: Writes the contents ofheroku configinto a local fileheroku config:push: Writes the contents of a local file intoheroku config
Run heroku help config:pull and heroku help config:push to see a full list of flags.
File Format
There's a lot of flexibility when it comes to how you can format your file. Key capitalization can go either way and there can be spacing around the = on one, both, or neither side. There can also be a leading export if you want to use the same file to populate your local environment. Since Heroku runs on linux, variable names must conform to those valid in unix. If you want to use unsupported characters in your var names, run commands with the -e flag. There's also support both unix and windows-style newlines (though only one type per file).
Multiline variables are fine as long as they're surrounded by "
All of the following are valid lines:
#comment
NODE_ENV= test
source =local
job = programming
DB_STRING=mongo://blah@thing.mongo.thing.com:4567
export THING=3
multiline="this can have
as many lines
# comments are still ignored
as it wants"
The following are all invalid lines:
# comment with leading space
bad_key=nono
key with-dash=andspace
multiline='bad because
it uses
single quotes'
Development
You'll need Node version >= 6.0. If you want to match exactly, check out the heroku cli's node version here. I like nvm for managing multiple node versions.
After cloning, follow these instructions to run locally! I welcome pull requests with fixes or new features.

Heroku 是一个商业的Rails主机托管解决方案，提供的是“无需准备的部署服务”，因为操作和扩展都是自动的，无需任何系统管理。虽然相较于其它服务商而言Heroku目前的价格较高。 为适应不断变化的需求，Heroku可以在网格中其它地方启动新的完全独立的dyno，或者关闭那些闲置的dyno。Dyno的启动时间还不到2秒，这足以证明Heroku的平台空前的强大。为了满足更高需求而启动新的dyno实
