🌌 Cosmic

Find and load configuration for your app, based on cosmiconfig, with fallback to environment variables.

⭐ Features

Cosmic, like cosmiconfig, will look for a configuration file:

• a package.json property
• a JSON or YAML, extensionless “rc file”
• an “rc file” with the extensions .json, .yaml, .yml, or .js.
• a .config.js CommonJS module

For example, if the app name is “cosmic”, these files will be searched:

• a cosmic property in package.json
• a .cosmicrc file in JSON or YAML format
• a .cosmicrc.json file
• a .cosmicrc.yaml, .cosmicrc.yml, or .cosmicrc.js file
• a cosmic.config.js file exporting a JS object

Apart from these, it also looks for:

• a cosmic.yaml, cosmic.yml, or cosmic.js file without “rc”
• Environment variables

💡 Usage

Install the package from npm:

npm install @anandchowdhary/cosmic

Import and use:

import { cosmic } from "@anandchowdhary/cosmic";

const config = await cosmic("project"); // {}

Use the config function to fetch a value:

import { cosmic, config } from "@anandchowdhary/cosmic";

await cosmic("project");
const environment = config("nodeEnv");

Clear the cache and fetch configuration available:

import { clearCosmicCache } from "@anandchowdhary/cosmic";

clearCosmicCache();

Sync functions are also available:

import { cosmicSync } from "@anandchowdhary/cosmic";

const config = cosmicSync("project"); // {}
