Readme
- 💻 Environment variables. Parses environment variables using your project's package.json name as a default prefix!
- 📁 Nested variables. Environment variable names are split by
__
and transformed into nested objects automatically! - 💯 Zero configuration. Boca works out-of-the-box using sensible defaults with no configuration required!
- 💪 TypeScript. Fully typed and self-documenting!
🚀 Quick Start
Install
# npm
npm i boca
# or yarn
yarn add boca
Import
// ESM / TypeScript
import { $parse } from "boca";
// or CommonJS
const { $parse } = require("boca");
Parse
// process.env = { BOCA_HOST: '0.0.0.0', BOCA_PORT: '3000' }
const config = $parse({ prefix: 'boca' });
console.log(JSON.stringify(config));
// => { "host": "0.0.0.0", "port": 3000 }
📃 Default Values
See options.defaults
.
📤 Default Export
$parse
is also exported as the default member so you can import Boca and parse your
environment variables in one line:
const config = require("boca")();
💪 TypeScript Generics
$parse
supports generics so you can have type definitions for your parsed environment variables:
const config = $parse<{ host: string; port: number }>();
// => config.host and config.port now have type definitions
⚙ Options
You can supply options to $parse
to configure Boca's parsing behaviour.
options.defaults
Any default values that should be used if an environment variable is not found.
options.format
Please see read-env
's documentation on this option as that is the
underlying library used by Boca to parse environment variables.
options.includePrefix
Whether the environment variable name prefix should be included or removed after being parsed by Boca.
By default, this is false (so the prefix is removed).
options.prefix
This is the prefix that will be used to filter out environment variables.
@
characters are removed, and -
and /
characters are replaced with _
to support NPM scoped package names.
For example, if the supplied prefix is @moducate/houston
, Boca will look for environment variables prefixed with MODUCATE_HOUSTON_
.
By default, your project's package.json name or current working directory name is used.
options.sanitize
Please see read-env
's documentation on this option as that is the
underlying library used by Boca to parse environment variables.
options.separator
The separator used to identify and transform nested objects.
If set to false, nested objects are disabled.
By default, the separator for nested objects is
__
.
options.source
The source to read environment variables from.
By default,
process.env
is used.
