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
  2. 创建
  3. 配置
  4. 部署
  5. 移除

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

$ npm run build
$ sls --debug

  express: 
    region:              ap-shanghai
    functionName:        ExpressComponent_7xRrrd
    apiGatewayServiceId: service-n0vs2ohb
    url:                 http://service-n0vs2ohb-1300415943.ap-shanghai.apigateway.myqcloud.com/release/

  36s › express › done

部署完毕后,可以在浏览器中访问返回的链接,看到对应的express返回值。

5. 移除

通过以下命令移除部署的存储桶

$ sls remove --debug

  DEBUG ─ Flushing template state and removing all components.
  DEBUG ─ Removed function ExpressComponent_MHrAzr successful
  DEBUG ─ Removing any previously deployed API. api-kf2hxrhc
  DEBUG ─ Removing any previously deployed service. service-4ndfl6pz

  13s › express › done

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

还支持哪些组件?

可以在 Serverless Components repo 中查询更多组件的信息。
