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。
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:
通过 npm 安装 serverless
$ npm install -g serverless
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
在 serverless.yml 中进行如下配置
# serverless.yml
express:
component: '@serverless/tencent-express'
inputs:
region: ap-guangzhou
runtime: Nodejs8.9

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

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
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。
如果已有腾讯云账号,可以在API 密钥管理中获取 SecretId
和SecretKey
.
# .env
TENCENT_SECRET_ID=123
TENCENT_SECRET_KEY=123
