Init Egg Project

$ mkdir egg-example && cd egg-example
$ npm init egg --type=simple
$ npm i

Change Egg Config

When cloud funtion executing, only /tmp folder is writable, so we need change the folder of logging for egg.js, then we change the configuration in config/config.default.js as below:

const config = (exports = {
  env: 'prod', // prod is recommended
  rundir: '/tmp',
  logger: {
    dir: '/tmp'

1. Install

Install the Serverless Framework globally:

$ npm install -g serverless

2. Create

In project root, create the following simple boilerplate:

$ touch serverless.yml
$ touch .env           # your Tencent api keys

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.

3. Configure

# serverless.yml

After egg project initialed, it will create app/public directory automatically. But when deploying, because it is empty, so this directory will not be uploaded. So when egg application start up, it will try to create app/public directory, but it can not write to it. So please create empty file .gitkeep in app/public directory.
