Inject Config

Inject global config to specific config

How To Use

Deafult global config path will be path.resolve(process.cwd(), './config'), you can change it with env INJECT_CONFIG_PATH.

import { inject } from '@blastz/inject-config';

type RedisConfig = {
  host: string;
  port: number;
};

export const redisConfig = inject<RedisConfig>('redis', {
  host: 'localhost',
  port: 6379,
});

If your globla config is

module.exports = {
  redis: {
    port: 520,
  },
};

When you import config from redis.config.ts the result will be

import { redisConfig } from 'config/redis.config.ts';

console.log(redisConfig);
// => { host: 'localhost', port: 520 }

CAUSTION: when you need to change the global config file path, you need to change env before import inject function.

process.env.INJECT_CONFIG_PATH = '/usr/src/config';

import { inject } from '../src';

Change array merge method

Overwrite the old array config

type ProxyConfig = {
  target: string;
};

const proxiesConfig = inject<ProxyConfig[]>('proxies', [], {
  arrayMerge: (_, sourceArray) => sourceArray,
});

Use in esmodule

Change global config file extension name to .cjs, then update INJECT_CONFIG_PATH to your cjs config file.

CAUSTION: import will execute before all your code, below change will not work

// main.mjs
process.env.INJECT_CONFIG_PATH = './config.cjs';

import appConfig from './app-config.mjs';

Add init-env.mjs to set environment.

// init-env.mjs
process.env.INJECT_CONFIG_PATH = './config.cjs';

// main.mjs
import './init-env.mjs';

import appConfig from './app-config.mjs';
