适配腾讯云的Serverless Nest组件
简介
Nest 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Nest框架。
快速开始
通过 Nest 组件,对一个 Nest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
通过 npm 安装 serverless、nestjs
$ npm install -g serverless
$ npm install -g @nestjs/cli
2. 创建
本地创建 serverless.yml
文件:
$ touch serverless.yml
初始化一个新的 Nest 项目:
$ nest new mynestjs
创建src/index.ts文件:
import { NestFactory } from '@nestjs/core';
import { AppModule } from './app.module';
import { ExpressAdapter } from '@nestjs/platform-express';
import * as express from 'express';
export const createApp = async (): Promise<express.Express> => {
const expressApp = express();
const adapter = new ExpressAdapter(expressApp);
const app = await NestFactory.create(AppModule, adapter);
app.enableCors();
await app.init();
return expressApp
}
3. 配置
在 serverless.yml 中进行如下配置
# serverless.yml
express:
component: 'serverless-nestjs-for-tencent'
inputs:
region: ap-guangzhou
4. 部署
如您的账号未登陆或注册腾讯云,您可以直接通过微信

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
$ npm run build

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
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
