Easily deploy koa applications to Tencent Cloud's serverless infrastructure using this Serverless Framework Component. Your application will auto-scale, never charge you for idle time, and require little-to-zero administration.

1. Install

$ npm install -g serverless

2. Create

Just create serverless.yml and .env files

$ touch .env # your Tencent API Keys
$ touch app.js
$ touch serverless.yml

Add the access keys of a Tencent CAM Role with AdministratorAccess in the .env file, using this format:

# .env
  • If you don't have a Tencent Cloud account, you could sign up first.

Initialize a new NPM package and install koa:

npm init          # then keep hitting enter
npm i --save koa  # install koa

create your koa app in app.js:

const koa = require('koa')
const app = new koa()

app.use(async (ctx, next) => {
  if (ctx.path !== '/') return next()
  ctx.body = 'Hello from Koa'

// set binary types
// app.binaryTypes = [*/*];

// don't forget to export!
module.exports = app
