$ cnpm install @ovotech/config-file 
SYNC missed versions from official npm registry.

Config File

Read a config file, and insert ENV vars where needed.


yarn add @ovotech/config-file


  "db": "db://user:${DB_PASSWORD}/db-name"
import { loadConfigFile } from '@ovotech/config-file';

interface Config {
  db?: string;

const config = loadConfigFile<Config>({ env: process.env, file: 'test.config.json', required: ['db'] });

Running the tests

You can run the tests with:

yarn test

Coding style (linting, etc) tests

Style is maintained with prettier and tslint

yarn lint


Deployment is preferment by lerna automatically on merge / push to master, but you'll need to bump the package version numbers yourself. Only updated packages with newer versions will be pushed to the npm registry.


Have a bug? File an issue with a simple example that reproduces this so we can take a look & confirm.
