@yandex-lms-ext/config
NodeJS application configuration library. It loads your configs as NodeJS modules, not JSONs.
Quick Start
Install package:
npm install @yandex-lms-ext/config
Create config
directory:
project/
config/
default.js
local.js
development.js
testing.js
production.js
Import library and use resulting config object:
import { config } from '@yandex-lms-ext/config';
console.log(config);
Define NODE_ENV
and run script:
NODE_ENV=development node index.js
config
object will include settings from config/default.js
, config/development.js
and config/local.js
.
If there is a conflict of keys, the objects will be expanded, arrays and primitives will be overridden.
Example
default.js
const config = {
logger: {
level: 'info'
},
server: {
port: 80,
ips: ['127.0.0.1']
}
};
module.exports = config;
development.js
const config = {
backend: {
baseUrl: 'https://dev-api.weather.yandex.ru/v1/'
},
static: {
baseUrl: '/static'
}
};
module.exports = config;
local.js
const config = {
backend: {
baseUrl: 'http://127.0.0.1:8090/v1/'
},
server: {
port: 8080,
ips: ['127.0.0.1', '192.168.1.69']
}
};
module.exports = config;
Resulting object:
const config = {
backend: {
baseUrl: 'http://127.0.0.1:8090/v1/'
},
logger: {
level: 'info'
},
server: {
port: 8080,
ips: ['127.0.0.1', '192.168.1.69']
},
static: {
baseUrl: '/static'
}
};
TypeScript integration
You can use this module in TypeScript projects without pain. See example
directory.
One caveat: you will have to describe your configuration manually.
