envoi
=====

[](#envoi)

Envoi aims to ease the use and documentation of environment variables (env vars) in PHP applications.

Envoi features:

- a Yaml schema to describe the env vars that may be used to configure an application
- tools to validate env vars against a schema
- a tool to assist in the population of a `.env` file
- a tool which converts a schema to markdown

Envoi sports a console command which validates a `.env` file against a schema (by convention, `.env.yaml`). It also provides checkers that, when invoked early in the start-up phase of an application, will halt an application which doesn't have a complete and valid set of env vars.

### Install

[](#install)

```
composer require linkorb/envoi
```

### Use

[](#use)

#### Env Checkers

[](#env-checkers)

A checker should be invoked as early as possible in the life-cycle of an application. The ideal time is immediately after the environment has been populated with env vars. For example, in a Symfony-based app, the checker should be invoked right after the Dotenv component has loaded the env vars from the various `.env*` files:
