快速部署 Express 框架

最近更新时间:2019-11-25 13:03:50

操作场景

Express 组件通过使用 serverless-tencent 的基础组件(如 API 网关组件、SCF 组件等),快速且方便地在腾讯云创建、配置和管理一个 Express 框架。

Serverless Framework + 腾讯云 >>

操作步骤

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,支持的命令如下:

安装

通过 npm 安装 Serverless:

$ npm install -g serverless

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')
})

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

配置

在 serverless.yml 中进行如下配置:

# serverless.yml

express:
  component: '@serverless/tencent-express'
  inputs:
    region: ap-shanghai

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:

$ sls --debug

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/密钥信息,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:

# .env
TENCENT_SECRET_ID=123
TENCENT_SECRET_KEY=123
