Serverless Express Tencent Cloud

 

腾讯云 Express 组件

简介

Express 组件通过使用 serverless-tencent 的基础组件如 API 网关组件,SCF 组件等,快速,方便的在腾讯云创建,配置和管理一个 Express 框架。

快速开始

通过 Express 组件,对一个 Express 应用进行完整的创建,配置,部署和删除等操作。支持命令如下:

  1. 安装
  2. 创建
  3. 配置
  4. 部署
  5. 移除

1. 安装

通过 npm 安装 serverless

$ npm install -g serverless

2. 创建

本地创建 serverless.yml 文件:

$ touch serverless.yml

初始化一个新的 npm 包,并安装 Express:

npm init              # 创建后持续回车
npm i --save express  # 安装express

创建一个 app.js文件,并在其中创建您的 Express App:

const express = require('express')
const app = express()

app.get('/', function(req, res) {
  res.send('Hello Express')
})

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

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

3. 配置

在 serverless.yml 中进行如下配置

# serverless.yml

express:
  component: '@serverless/tencent-express'
  inputs:
    region: ap-guangzhou
    runtime: Nodejs8.9

4. 部署

如您的账号未登陆注册腾讯云,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

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

$ touch .env # 腾讯云的配置信息

.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

如果已有腾讯云账号,可以在API 密钥管理中获取 SecretIdSecretKey.

# .env
TENCENT_SECRET_ID=123
TENCENT_SECRET_KEY=123
