Blueconfig is schema validator for your config files on production or development environment. Blueconfig merges configs and validates them depending of a pattern called *schema*. Configs can be an object or a file (json, yaml...).

Introducing a configuration schema, blueconfig gives project collaborators more **context** on each setting and enables **validation and early failures** for when configuration goes wrong.

*This is a fork of node-convict 5.x because I had lot of changes todo (more than the workflow of node-convict can process).*

# Why Blueconfig ?

 1) Merge several config in one ;
 2) Support environmental variables and Command-line arguments ;
 2) Validate your config with your schema ;
 3) Customize your schema and your validation (with custom format, type and type converter) ;
 5) Use your own file format (JSON, JSON5, YAML, TOML, XML...) ; *(JSON5 allows comment)*
 6) Only 3 dependancies (Blueconfig 7.0 will have only 2 dependancies).

**Install:** `npm install blueconfig`
