Config is a pluggable dynamic config package

Most config in applications are statically configured or include complex logic to load from multiple sources.
|
|
|
|
|
Go Config makes this easy, pluggable and mergeable. You'll never have to deal with config in the same way again.

## Features
|
|
|
|
|
|
|
|
|
|
- **Dynamic Loading** - Load configuration from multiple source as and when needed. Go Config manages watching config sources
|
|
|
|
|
in the background and automatically merges and updates an in memory view.
|
|
|
|
|
|
|
|
|
|
- **Pluggable Sources** - Choose from any number of sources to load and merge config. The backend source is abstracted away into
|
|
|
|
|
a standard format consumed internally and decoded via encoders. Sources can be env vars, flags, file, etcd, k8s configmap, etc.
|
|
|
|
|
|
|
|
|
|
- **Mergeable Config** - If you specify multiple sources of config, regardless of format, they will be merged and presented in
|
|
|
|
|
a single view. This massively simplifies priority order loading and changes based on environment.
|
|
|
|
|
|
|
|
|
|
- **Observe Changes** - Optionally watch the config for changes to specific values. Hot reload your app using Go Config's watcher.
|
|
|
|
|
You don't have to handle ad-hoc hup reloading or whatever else, just keep reading the config and watch for changes if you need
|
|
|
|
|
to be notified.
|
|
|
|
|
|
|
|
|
|
- **Sane Defaults** - In case config loads badly or is completely wiped away for some unknown reason, you can specify fallback
|
|
|
|
|
values when accessing any config values directly. This ensures you'll always be reading some sane default in the event of a problem.
