koa-initializer

A koa plugin for handling async/sync initializers of your application.

Installation

npm install koa-initializer

When should I use koa-initializer?

You need to add synchronous or asynchronous code, that must be executed before your koa app starts.

API

const initializer = require('koa-initializer');
const Koa         = require('koa');
const app         = new Koa();

// koa v2

initializer(app)
.then(() => {
    //Your application code
});

// koa v3
await initializer(app);
//Your application code

So as you can see initializer returns promise;

Initializer file path and structure

Your app root folder should contain "initializers" folder with initializers files (name of file irrelevant). initializer.js:

'use strict';

module.exports = {
    priority: 800, // Any diapason (bigger number - higher priority, so 1000 goes before 800)
    execute(app) { // Executable function (takes app as parameter)
        //Any synchronous/asynchronous code (asynchronous must return promise)
    }
};
