Environments

With environments, you can define different configurations depending on the environment type your app is currently running.

It is recommended to have 4 types of environments: development, testing, staging, production. After app.launch you can always access the current environment vars via app.env.

all.ts

export = {
  name:'all',
  someVar:'someVar'
}

development.ts

export = {
  name:'develpment',
  db:'mongo://development-url'
}

testing.ts

export = {
  name:'testing',
  db:'mongo://testing-url'
}

If we launch our app.js with NODE_ENV = testing

import {createApp}  from '@appolo/core';
...
let app = await createApp().launch();
var env = app.env;
console.log(env.name,env.someVar,env.db) // 'testing someVar monog://testing-url'

Env Injection#

the env object can be injected to any class.

import {define,initMethod,inject} from '@appolo/inject';

@define()
export class BaseManager {
    @inject() env:IEnv

    private getData(){
        console.log(this.env.name)
    }
}
