### 0. 准备
#### 初始化 Egg 项目
```bash
$ mkdir egg-example && cd egg-example
$ npm init egg --type=simple
$ npm i
```
#### 新增初始化文件
在项目根目录下新建文件 `sls.js`,内容如下:
```js
const { Application } = require('egg');
const app = new Application({
env: 'prod',
});
module.exports = app;
```
#### 修改 Egg 配置
由于云函数在执行时,只有 `/tmp` 可读写的,所以我们需要将 `egg.js` 框架运行尝试的日志写到该目录下,为此需要修改 `config/config.default.js` 中的配置如下:
```js
const config = (exports = {
env: 'prod', // 推荐云函数的 egg 运行环境变量修改为 prod
rundir: '/tmp',
logger: {
dir: '/tmp',
},
});
```
#### 注意事项
由于 `egg` 的 `egg-static` 静态资源插件是默认开启的,所以在启动应用时,会尝试创建 `app/public` 目录,但是云函数执行环境只有 `/tmp` 可读写,所以需要本地创建,并添加 `.gitkeep` 文件(为空就好)。
但是如果你并不想使用静态资源,可以修改 `config/plugin.js` 来禁用它:
```js
module.exports = {
static: {
enable: false,
},
};
```
如果需要开启静态资源功能,并且 public 已经存在,且里面包含静态资源。
此时需要配置 `binaryTypes`,修改 `sls.js` 文件如下:
```js
const { Application } = require('egg');
const app = new Application({
env: 'prod',
});
// 这里可以根据实际情况来配置
// 如果你的站点开启gzip,那么所有返回类型都应该是二进制类型,所以应该是 `app.binaryTypes = ['*/*']`
app.binaryTypes = ['image/*'];
module.exports = app;
```

### 1. 安装
通过 npm 全局安装 [serverless cli](https://github.com/serverless/serverless)
```bash
$ npm install -g serverless
```
### 2. 配置
在项目根目录创建 `serverless.yml` 文件,在其中进行如下配置
```bash
$ touch serverless.yml
```
```yml
# serverless.yml
MyComponent:
component: '@serverless/tencent-egg'
inputs:
region: ap-beijing
functionName: egg-function
code: ./
functionConf:
timeout: 10
memorySize: 128
environment:
variables:
TEST: vale
vpcConfig:
subnetId: ''
vpcId: ''
apigatewayConf:
protocol: https
environment: release
```

### 3. 部署
如您的账号未 [登陆](https://cloud.tencent.com/login) 或 [注册](https://cloud.tencent.com/register) 腾讯云,您可以直接通过 `微信` 扫描命令行中的二维码进行授权登陆和注册。
通过 `sls` 命令进行部署,并可以添加 `--debug` 参数查看部署过程中的信息
```bash
$ sls --debug
DEBUG ─ Resolving the template's static variables.
DEBUG ─ Collecting components from the template.
DEBUG ─ Downloading any NPM components found in the template.
DEBUG ─ Analyzing the template's components dependencies.
DEBUG ─ Creating the template's components graph.
DEBUG ─ Syncing template state.
DEBUG ─ Executing the template's components graph.

```
> 注意: `sls` 是 `serverless` 命令的简写。
### 4. 移除
通过以下命令移除部署的 API 网关和云函数
```bash
$ sls remove --debug
DEBUG ─ Flushing template state and removing all components.
DEBUG ─ Removing function
DEBUG ─ Request id
DEBUG ─ Removed function egg-function successful
DEBUG ─ Removing any previously deployed API. api-cmkhknda
DEBUG ─ Removing any previously deployed service. service-n5m5e8x3

```
### 账号配置(可选)
当前默认支持 CLI 扫描二维码登录,如您希望配置持久的环境变量/秘钥信息,也可以本地创建 `.env` 文件
```bash
$ touch .env # 腾讯云的配置信息
```
在 `.env` 文件中配置腾讯云的 SecretId 和 SecretKey 信息并保存
如果没有腾讯云账号,可以在此 [注册新账号](https://cloud.tencent.com/register)。
如果已有腾讯云账号,可以在 [API 密钥管理](https://console.cloud.tencent.com/cam/capi) 中获取 `SecretId` 和`SecretKey`.
```text
# .env
TENCENT_SECRET_ID=123
TENCENT_SECRET_KEY=123
```
